ILASIK Step by Step: The Femtosecond Flap, the Excimer Laser and the Minutes in Between

The waiting room is quiet in the way waiting rooms are when everyone has left their glasses at home. A man in his late thirties is squinting at a laminated card the nurse handed him, not because he can read it, but because squinting is what he has done for twenty-five years. He has watched three videos about laser eye surgery. He still cannot picture the part where the lights go out.

That gap between what the brochures show and what the eye actually experiences is the reason this explainer exists. The ilasik procedure steps are short, precise and, for most people, stranger than they are painful. Two different lasers do two different jobs, and the few minutes between them are where the surgeon does the most careful work of the day.

What follows is a walk through each stage, what the evidence says about comfort and recovery, and the questions worth asking before you lie down under the machine.

What ILASIK actually means, and the ilasik procedure steps in one picture

Start with the word itself, because it causes more confusion than any laser. LASIK stands for laser-assisted in situ keratomileusis, a phrase that simply means reshaping the cornea, the clear front window of the eye, with a laser after lifting a thin protective layer. The letter in front marks a particular version: a trademarked label for LASIK in which a femtosecond laser makes the flap instead of a mechanical blade, and the reshaping laser is guided by a wavefront map of your individual eye. In plain terms, it is bladeless, custom-mapped LASIK. The Mayo Clinic describes both the femtosecond flap and wavefront guidance as standard options within modern LASIK rather than a separate operation.

Because the steps are the same whichever label a surgeon uses, the table below is the whole procedure at a glance. Each row is expanded later in the article.

Stage	What happens	What you typically notice
Mapping	Corneal thickness, shape and wavefront measurements	Bright targets, a chin rest, several minutes per test
Preparation	Numbing drops, cleaning, eyelid holder placed	Pressure from the holder, no sharp sensation
Femtosecond flap	Laser creates a hinged layer inside the cornea	Suction ring, vision dims or goes dark for seconds
The minutes between	Flap lifted, laser platforms switched	Blurry light, the surgeon talking you through
Excimer reshaping	Ultraviolet laser sculpts the exposed tissue	Clicking sound, faint odor, blinking light to fixate
Flap repositioned	Flap laid back, smoothed, no stitches	Cool drops, watery eyes, hazy vision

The Mayo Clinic notes that the whole sequence for both eyes is usually completed in 30 minutes or less. The laser time inside that window is measured in seconds.

How does LASIK reshape the cornea? The mechanism in plain words

Think of the cornea as the eye’s fixed front lens. Roughly two thirds of the eye’s focusing power comes from its curve, and when that curve is slightly too steep, too flat or unevenly shaped, light lands in front of, behind or smeared across the retina. That is nearsightedness, farsightedness and astigmatism, respectively. Glasses and contact lenses correct the error by adding a lens in front. LASIK corrects it by changing the curve itself.

The correction happens in a layer called the stroma, the thick middle portion of the cornea that sits under a thin surface skin. The excimer laser removes microscopic amounts of stromal tissue in a pattern computed from your measurements. For a nearsighted eye, the center is flattened slightly; for a farsighted eye, the periphery is treated so the center becomes relatively steeper; astigmatism is treated by removing tissue unevenly to even out the curve. Cleveland Clinic and MedlinePlus both describe the amount removed as thinner than a human hair for typical prescriptions.

The reason a flap exists at all is protection and speed of healing. Reshaping directly on the surface, as in an older technique called PRK, means the surface skin must regrow over days and vision recovers more slowly. Lifting a hinged flap, reshaping underneath and laying the flap back allows the surface to be largely intact within hours, which is why LASIK patients often notice improved vision the same day, according to Mayo Clinic guidance.

Wavefront guidance adds one more layer of detail. Instead of programming the laser only from your glasses prescription, the system measures how a beam of light is distorted as it passes through your whole optical system, then aims to correct those subtle irregularities as well as the main error. Whether that translates into better night vision for a given person is something your surgeon should discuss honestly; the evidence is favorable but not uniform.

Before the laser: wavefront mapping, safety checks and numbing drops

The first appointment is often longer than the surgery. A technician measures the thickness of your cornea, because there must be enough tissue left after reshaping to keep the eye structurally sound. Corneal topography, a color map of the curve, looks for hidden irregularities such as early keratoconus, a condition in which the cornea thins and bulges and which rules LASIK out. Pupil size is recorded in dim light. Tear film is assessed, since pre-existing dry eye is one of the most common reasons a team suggests waiting or choosing a different approach, as Mayo Clinic notes.

The wavefront measurement is the step that gives this version its name. You look at a target while a low-intensity light is bounced off the retina and back out through your lens and cornea. Sensors compare the returning wave to a perfect one and produce a fingerprint of your eye’s optical errors. That fingerprint becomes the treatment profile programmed into the excimer laser on the day.

Contact lens wearers are usually asked to stop wearing lenses before these measurements, because lenses temporarily mold the cornea. Cleveland Clinic advises a break beforehand, with the exact length set by your team and longer for rigid lenses. Skipping this step can lead to a treatment based on a distorted map.

On the day, you arrive without eye makeup, lotions or perfume, which can interfere with the laser or increase infection risk. Anesthetic drops numb the surface within a minute or two. Some centers offer a mild oral sedative; that is a decision for the treating team and is not universal. The eyelids are cleaned, a sterile drape is placed, and a small spring device called a speculum holds the lids open. It feels like firm pressure, not pain, and it removes the worry that so many people voice beforehand: you cannot blink at the wrong moment.

Femtosecond laser LASIK: what happens when the flap is made and why the lights dim

A femtosecond laser fires pulses lasting a quadrillionth of a second, so brief that the energy separates tissue without heating it. Millions of tiny bubbles are placed side by side at a precise depth inside the cornea, creating a flat plane with a hinge left at one edge. Johns Hopkins Medicine describes this bladeless method as the standard alternative to the mechanical microkeratome, a small oscillating blade used in earlier LASIK.

Here is the sequence you will feel. A suction ring, a soft circle slightly larger than the cornea, is lowered onto the eye and gently attached. Its job is to hold the eye perfectly still and to flatten the cornea against a clear plate so the laser depth is exact. The suction raises pressure inside the eye briefly, and that pressure is what makes your vision fade to gray or black for a handful of seconds. The Mayo Clinic notes this dimming as expected and temporary. Patients often describe a heavy, dull sensation; sharp pain would be unusual and worth telling the surgeon about immediately.

The laser itself runs for well under a minute per eye. There is a faint tapping or buzzing sound. You will be asked not to move, but you will also be told that the machine tracks your eye, so a small drift is not a disaster. When the pattern is complete, suction is released, vision returns as a bright blur, and the surgeon moves to the second eye or, on some platforms, immediately to the next stage.

Why does the femtosecond approach matter? Flap thickness and shape are more predictable than with a blade, which is why many surgeons prefer it for thinner corneas. That predictability is a matter of surgical planning rather than a guarantee of a better outcome, and your team can explain which factors apply to you.

The minutes in between: lifting the flap and switching lasers

This is the part no brochure lingers on and the part patients most often say surprised them. Depending on the operating room, you may be moved from one laser bed to another, or the bed may swivel between two machines. Either way, there is a pause of a few minutes in which the femtosecond work is done and the excimer work has not begun.

The surgeon uses a fine blunt instrument to separate the last bubbles along the plane and lift the flap on its hinge, folding it back like the cover of a book. You will see the world go soft and watery as the flap moves, then a bright circle of light as the exposed stroma is checked and dried with a small sponge. Most people report this as odd rather than uncomfortable; the surface is fully numb.

Several things are happening that you cannot see. The surgeon confirms the flap edges are clean and the bed is free of debris. The excimer system loads your wavefront profile and checks that the eye on the table matches the eye in the file, often using iris registration, a method that photographs the unique pattern of the colored ring around your pupil and aligns the treatment to it even if the eye has rotated slightly since the measurements. Cleveland Clinic explains that this alignment step is what allows the laser to treat astigmatism on the correct axis.

The surgeon will talk. You will be asked to look at a blinking light, usually red or green, and to keep your gaze fixed on it. This is the single most useful thing you can do during the whole procedure, and it is easier than it sounds because the light is the only sharp thing in view. If you lose it, say so; the laser pauses when the tracker loses your eye.

The excimer laser step: how long does LASIK take once the reshaping starts?

An excimer laser produces cool ultraviolet light that breaks molecular bonds at the very surface of tissue, removing an extraordinarily thin layer with each pulse and leaving what lies beneath untouched. The name comes from the excited gas mixture inside the machine. It does not cut; it vaporizes, one pulse at a time, in a pattern the computer has already drawn from your wavefront map.

The reshaping itself is the shortest stage of the entire day. MedlinePlus and Mayo Clinic both describe the laser time as under a minute per eye for most prescriptions, sometimes only tens of seconds. Higher corrections take longer because more pulses are required. Across the whole visit, from lying down to sitting up, the Mayo Clinic gives 30 minutes or less for both eyes.

You will hear a steady clicking as the pulses fire, and many people notice a faint smell often compared to burnt hair. It is not your eye burning; it is the odor of tissue being vaporized in microscopic amounts, and it disappears as soon as the laser stops. The blinking fixation light may seem to jump or shimmer as the corneal surface changes shape beneath it. That is expected.

Modern platforms track eye position hundreds of times per second and shift the beam to follow small movements. If you move beyond what the tracker can follow, the laser stops automatically and the surgeon resumes when you are steady. Knowing this in advance helps, because the fear of ruining the surgery with a flinch is one of the most common anxieties reported before the procedure, and the machine is built precisely so that a flinch does not do that.

When the pulses finish, the surgeon rinses the bed with sterile fluid and reaches for the flap.

Repositioning the flap and the first hour afterward

The flap is floated back into place on a film of fluid and smoothed outward from the hinge with a wet sponge so that no wrinkles or debris remain. No stitches are used. Within a few minutes the cornea’s own pumping cells draw fluid out of the interface and the flap adheres by suction, which is why you are asked not to rub or squeeze the eye afterward. Johns Hopkins Medicine describes the flap as sealing naturally over the following hours, with full edge healing taking longer.

Drops go in: usually an antibiotic to reduce infection risk and an anti-inflammatory to calm the surface. Your surgeon decides the exact regimen and duration; those are prescribing decisions and vary by person. The speculum comes out. You are helped to sit up, and the first thing most people do is look at the clock on the wall and notice it is a clock, hazy but recognizable.

The surgeon examines the flap under a slit lamp, a microscope with a bright beam, to confirm it is sitting correctly before you leave. You will be given clear plastic shields to tape over the eyes while sleeping for the first several nights, and dark glasses for the ride home. Driving yourself is not possible; the Mayo Clinic advises arranging transport and expecting hazy, watery vision for the rest of the day.

The first few hours can be the least comfortable of the whole experience. Mayo Clinic lists itching, burning, grittiness and light sensitivity as typical once the anesthetic wears off, usually with mild pain at most. Closed eyes and a nap are the standard advice. A follow-up examination is normally scheduled within 1–2 days, when the flap is checked again and vision is measured for the first time.

Who is ILASIK usually for, and who is usually asked to wait?

The eligibility conversation matters more than any single step under the laser, because the best predictor of a smooth outcome is choosing the right eyes to treat. Mayo Clinic and Cleveland Clinic list the typical criteria: adults, usually at least 18 and often older, with a glasses prescription that has been stable for at least a year, corneas thick and regular enough to leave a safe margin, healthy eye surfaces and no active eye disease.

The best age question comes up constantly. Prescriptions tend to drift through the late teens and early twenties, which is why many surgeons prefer to wait until the mid twenties even though the lower legal threshold is younger. At the other end, presbyopia, the normal age-related loss of near focus, begins in the forties. LASIK does not stop it. Someone at 40 with clear distance vision after surgery may still need reading glasses within a few years, a point Mayo Clinic makes explicitly. Some teams offer monovision, correcting one eye for distance and one for near, which suits some people and not others; a contact lens trial is the usual way to find out.

People commonly asked to wait or to consider an alternative include those who are pregnant or breastfeeding, because hormones can temporarily change the cornea and prescription; those with uncontrolled diabetes or autoimmune conditions that affect healing; anyone with significant dry eye or a history of herpes eye infection; people whose corneal maps show thinning or irregularity; and those whose prescription is still changing. Certain occupations or sports with high risk of eye impact may steer a team toward a surface procedure without a flap.

None of these are judgments. They are the screening that separates a predictable outcome from an avoidable problem, and the final call always rests with the surgeon who has your measurements in front of them.

How painful is LASIK surgery? What the evidence says about the day and the days after

The honest answer has two parts, because the procedure and the recovery feel different.

During the procedure, pain is not the dominant sensation. Anesthetic drops numb the corneal surface fully within minutes, and the cornea has no pain fibers deep in the stroma where the reshaping happens. What people describe instead is pressure from the eyelid holder and the suction ring, the brief and disconcerting fade to gray, and a sense of something being done to an eye that cannot blink. Mayo Clinic characterizes discomfort during LASIK as minimal. Anxiety, not pain, is what most surgeons spend their words managing.

Afterward is a different story for the first several hours. As the drops wear off, the disrupted surface cells around the flap edge report in. Mayo Clinic lists burning, itching, a foreign-body or gritty feeling, watering and sensitivity to light as typical, and describes the pain as usually mild. Cleveland Clinic gives a similar picture and notes that most people feel markedly better by the next morning. Sleeping through the worst of it is the standard advice, which is one reason many centers schedule surgery earlier in the day.

Pain that increases rather than settles over the first day, or that returns sharply days later, is not typical and belongs in the red-flag list at the end of this article.

Compared with PRK, the surface technique without a flap, LASIK is generally the more comfortable recovery, since PRK leaves an open surface that takes several days to re-epithelialize. That difference is one of the main reasons LASIK became the more common choice, though PRK remains preferable for some corneas.

What about pain medicine? Teams commonly suggest over-the-counter options for the first evening and prescribe lubricating and anti-inflammatory drops; those choices, and how long to use them, are individual decisions for your prescribing clinician.

LASIK recovery time: what the days and weeks after the ILASIK procedure steps usually look like

Recovery is fast at the start and slow at the finish, and knowing that shape prevents a lot of worry.

The first evening is haze, watering and rest. By the next morning, many people can see well enough to function without glasses, though vision often fluctuates through the day. Mayo Clinic notes that vision may be blurry or hazy for a day or two and that many people return to work within 1–2 days. The first follow-up visit falls in that window and confirms the flap is in place.

The first week is about protecting the flap. No rubbing. Shields at night. No eye makeup. No swimming, hot tubs or dusty environments, with Mayo Clinic advising a wait of a couple of weeks or more before water exposure; your team sets the exact interval. Showering is fine with care to keep soap and direct spray out of the eyes. Screens are allowed, though they dry the surface, so frequent lubricating drops are the norm.

The first month brings the classic side effects. Dry eye is the most common, because the flap cut interrupts corneal nerves that trigger tear production; they regrow over months. Mayo Clinic says dryness can persist for up to 6 months in some people. Glare, halos around lights and reduced contrast at night are also common early and usually improve as the cornea smooths and swelling resolves.

Vision stabilization takes longer than most expect. Mayo Clinic gives 2–3 months for final visual results to settle, and surgeons generally will not judge whether an enhancement, a small second treatment, is warranted until then. Follow-up visits are typically scheduled at intervals across that period.

Contact sports and activities with a risk of eye impact are usually restricted for several weeks, longer for high-impact sports. The flap gains strength over months, though it never regains the full tensile strength of the untouched cornea, which is why eye protection remains sensible long term.

What is the fail rate for LASIK? Risks, retreatments and the alternatives

The phrase fail rate does not map neatly onto how eye surgeons think, so it helps to separate three different things: complications, side effects and under- or over-correction.

Complications are events such as flap problems, infection or inflammation under the flap. The NHS and Mayo Clinic both describe serious complications as uncommon, and complications leading to permanent vision loss as rare. Femtosecond flaps have reduced some blade-related flap problems, though they introduce their own rare issues such as gas bubbles or light sensitivity in the early weeks. Ectasia, a progressive bulging of a weakened cornea, is the most serious late complication and is the reason so much attention is paid to corneal thickness and topography at screening.

Side effects are expected and usually temporary: dry eye, glare, halos, fluctuating vision. In a minority they persist beyond the typical window and become a genuine quality-of-life issue. Anyone with significant dry eye before surgery is at higher risk, which is why honest reporting of symptoms at the screening visit matters.

Under- or over-correction means the laser removed slightly less or more than intended, or the eye healed in a way that left residual error. The usual response, once vision has stabilized, is an enhancement. The NHS notes that a proportion of people need a further procedure to fine-tune the result; whether that applies to you depends on your prescription and healing and is something your surgeon can discuss without promising a number.

Alternatives exist and are not second-best. PRK reshapes the surface without a flap, useful for thinner corneas or high-impact occupations, at the cost of a slower, sorer recovery. SMILE, a lenticule extraction technique in which a femtosecond laser cuts a small lens-shaped piece of tissue that is removed through a tiny incision, avoids a large flap. Implantable lenses are options for very high prescriptions. Glasses and contact lenses remain perfectly reasonable choices, and no reputable team will suggest otherwise.

What people often get wrong about ILASIK

The laser removes the flap. It does not. The femtosecond laser creates a hinged layer that is folded back and replaced; nothing is thrown away except the microscopic tissue vaporized by the excimer laser underneath. The flap remains part of your cornea permanently.

You have to hold perfectly still or the laser will cut in the wrong place. Modern platforms track the eye many times per second and pause automatically if you move beyond a set limit. Fixating on the light helps, but the system is designed around the reality that eyes move.

Bladeless means painless, and blade means painful. Neither is true. Anesthetic drops make both approaches essentially painless during the procedure. The femtosecond flap offers more predictable thickness, which is a planning advantage, not a comfort one.

The results are permanent so you will never need glasses. The corneal reshaping is permanent, but the eye keeps aging. Presbyopia arrives in the forties regardless, and Mayo Clinic notes that cataracts and other age-related changes proceed as they would have. Some people also experience slow regression of the correction over years.

Wavefront-guided treatment guarantees perfect night vision. Wavefront mapping aims to reduce higher-order aberrations that contribute to halos, and evidence suggests it helps some people. It does not eliminate night symptoms for everyone, and early glare is expected regardless of platform.

Dry eye after LASIK is just a nuisance. For most it fades over months as nerves regrow. For a minority it is persistent and genuinely affects daily life, which is why teams screen for it and why anyone with existing dry eye deserves a frank conversation before booking.

If you can see the next morning, you are healed. Vision often looks good early, but the flap edge is still knitting and the cornea is still settling for weeks. Mayo Clinic’s 2–3 month stabilization window is when results are actually judged.

Questions to ask your care team before the ilasik procedure steps begin

A good consultation should leave you with fewer questions than you arrived with, but only if you bring the right ones. These are the questions experienced surgeons tend to welcome.

• What did my corneal thickness and topography show, and how much tissue would remain after treatment? Is there anything on the map that gives you pause?
• Do my measurements suggest I am a better candidate for LASIK, PRK, a lenticule extraction technique or a lens-based option, and why?
• How dry are my eyes right now on your tests, and how would you expect that to change in the months after surgery?
• Will you use wavefront-guided or wavefront-optimized treatment for my eyes, and what difference does that make for someone with my prescription and pupil size?
• How many procedures like mine do you personally perform, and how do you handle the situation if the flap is not ideal on the day?
• What is your policy on enhancements if my vision is under- or over-corrected once it stabilizes, and how long do you wait before deciding?
• I am in my forties: what should I expect about reading vision, and is a monovision trial in contact lenses worth doing first?
• Which drops will I use, for how long, and who do I call on a weekend if something feels wrong?
• What activities are off limits, and for how long, given my job and sports?
• What would make you cancel on the day of surgery?

Write the answers down, or bring someone who will. Anesthetic drops and nerves make for poor memory, and the details about follow-up timing and restrictions are exactly the ones that matter most in the first week. If a team seems reluctant to discuss alternatives or risks in plain language, that reluctance is itself useful information.

When to call your doctor: red-flag signs after LASIK

Most of what you feel in the first day is expected: burning, grittiness, watering, light sensitivity and blur that comes and goes. The signs below are different. They are uncommon, but they are the reasons your team gives you an out-of-hours number, and they warrant a same-day call rather than waiting for the scheduled visit.

• Pain that worsens after the first few hours instead of easing, or severe pain at any point, particularly if it wakes you or is not relieved by rest and the drops you were given.
• A sudden drop in vision in either eye after it had been improving, or vision that becomes markedly worse than the day before.
• Increasing redness, especially with a yellow or white discharge, which can signal infection.
• A sensation that something has shifted or wrinkled on the eye, or new distortion, doubling or waviness in one eye, which can indicate a flap that has moved or developed folds. This is more likely after rubbing or an impact and needs prompt examination.
• New floaters, flashes of light or a curtain or shadow across part of your vision. These are not typical of LASIK itself but signal a retinal problem that needs urgent assessment, and people with high nearsightedness carry a higher baseline risk.
• Any direct blow to the eye in the weeks after surgery, even if it feels fine afterward.
• Light sensitivity that intensifies over days rather than fading, or an eye that becomes increasingly difficult to open.

Mayo Clinic and Cleveland Clinic both advise contacting the surgical team promptly for worsening symptoms, and going to an emergency department if the team cannot be reached and vision is deteriorating or pain is severe. Do not remove a flap shield to inspect the eye yourself, and do not put in any drops that were not prescribed for you.

Every decision about what to do next, from adjusting drops to lifting and repositioning a flap, sits with the treating surgeon. Your job in the first weeks is simply to notice, and to call.

Frequently asked questions

How painful is LASIK surgery on the day?

Pain during LASIK is minimal for most people because anesthetic drops fully numb the corneal surface. What you feel is pressure from the eyelid holder and suction ring, a brief dimming of vision, and the oddness of not being able to blink. Mayo Clinic describes the discomfort as slight. The gritty, burning sensation arrives a few hours later as the drops wear off and usually settles overnight.

How long does LASIK take from start to finish?

Both eyes are usually completed in 30 minutes or less, according to Mayo Clinic. Within that, the femtosecond flap takes well under a minute per eye and the excimer reshaping often takes only tens of seconds. Most of the time is spent on positioning, drops, checking the flap and switching between the two laser platforms. Expect to be at the center for a couple of hours including preparation and the post-procedure check.

Is femtosecond laser LASIK safer than the blade method?

The femtosecond laser produces flaps of more predictable thickness and shape than a mechanical blade, which reduces certain flap-related complications and helps surgical planning for thinner corneas. It introduces its own rare issues, such as temporary light sensitivity in the early weeks. Neither method is painful during the procedure, and overall outcomes depend far more on careful candidate selection than on how the flap is made.

Is LASIK worth it at 40?

That depends on what you want it to fix. LASIK can correct distance vision at 40 as it can at 30, but presbyopia, the normal loss of near focus, begins around that age and continues regardless of surgery. Mayo Clinic notes that reading glasses may still be needed. Some teams offer monovision or suggest a contact lens trial first. The decision is individual and belongs with you and your surgeon.

What is the fail rate for LASIK?

There is no single fail rate because the term mixes different things. Serious complications are described as uncommon by the NHS and Mayo Clinic, and permanent vision loss as rare. Temporary side effects such as dry eye and halos are common. Some people end up slightly under- or over-corrected and are offered an enhancement once vision stabilizes. Your surgeon can discuss the risks that apply to your specific measurements.

At what age is it best to get LASIK?

Most guidance sets a minimum of 18, and many surgeons prefer the mid twenties, because prescriptions often keep changing through the early twenties and Mayo Clinic advises a stable prescription for at least a year before surgery. There is no single ideal age; the practical sweet spot for many is after the prescription has settled and before presbyopia complicates expectations in the forties.

What is the typical LASIK recovery time before I can work and drive?

Many people return to work and, once their surgeon confirms vision meets the legal standard at the first follow-up, resume driving within 1–2 days, according to Mayo Clinic. Vision often fluctuates over the first weeks, dry eye and halos are common early, and final results are judged at 2–3 months. Swimming, eye makeup and contact sports are usually restricted for longer, with your team setting the exact intervals.

Why does my vision go black during the flap step?

The suction ring that holds the eye steady for the femtosecond laser raises pressure inside the eye for a few seconds. That temporary pressure interrupts blood flow to the retina briefly, so vision dims or goes dark. It returns as soon as suction is released. Surgeons warn patients about this in advance because it is startling, but it is an expected part of the flap stage rather than a complication.

Can the flap move or come loose after LASIK?

The flap adheres by natural suction within minutes and gains strength over weeks, but it can be displaced by rubbing or a direct blow, especially in the first days. That is why shields are worn at night and rubbing is off limits. Sudden distortion, a feeling that something has shifted, or a drop in vision after an impact should prompt a same-day call to your surgical team.

What are the alternatives if I am not a good candidate for LASIK?

PRK reshapes the corneal surface without a flap and suits thinner corneas or high-impact occupations, with a slower and sorer recovery. Lenticule extraction techniques remove a small lens-shaped piece of tissue through a tiny incision. Implantable lenses are options for very high prescriptions. Glasses and contact lenses remain entirely reasonable choices, and a good team will explain which option fits your measurements and goals.
