Corneal Repair Recovery: The Eye Shield, Drop Routine and Why Vision Clears Gradually

The night after surgery, most people notice the same odd thing: the plastic shield taped over one eye feels like the least medical object in the room, yet the surgeon spent more time explaining it than the operation itself. Then comes the paper chart of drops, one column of times, another of bottle caps, and the quiet worry that the world on that side still looks like frosted glass.

Corneal repair recovery is a slow, structured process, whether the operation was a transplant for a scarred or clouded cornea or a stitched repair after an injury. The cornea is the clear front window of the eye, and it has almost no blood vessels, which is why it heals more deliberately than skin. That fact shapes almost everything that follows: the shield, the drops, the months of follow-up.

This explainer walks through what is actually happening under the shield, why the drop routine is not optional, and why an eye that looks unchanged in the mirror can still be doing exactly what it should.

What actually happens during corneal repair, and why the cornea heals slowly

The cornea is a dome of clear tissue about half a millimeter thick, layered like a pastry: a surface skin called the epithelium, a thick middle layer called the stroma, and a single sheet of pump cells at the back called the endothelium. Those pump cells keep the cornea dehydrated enough to stay transparent. When any layer is badly scarred, swollen or torn, light scatters instead of focusing, and vision blurs.

“Corneal repair” covers two broad situations. In a corneal transplant, also called keratoplasty, a surgeon removes the damaged portion and replaces it with donor tissue, either the full thickness of the cornea or just the diseased layer. In a traumatic repair, the surgeon closes a laceration, meaning a cut through the cornea, with sutures finer than a human hair. Mayo Clinic describes the main transplant approaches, from full-thickness penetrating keratoplasty to endothelial procedures that replace only the back layer.

Why so slow afterward? Skin heals quickly because blood carries oxygen, nutrients and repair cells straight to the wound. A healthy cornea has no blood vessels at all; it draws oxygen from the air and nutrients from tears and the fluid behind it. That avascular design is what keeps it transparent, and it is also why the tissue knits together over months rather than days. Stitches placed in the cornea may remain for many months, sometimes longer, because the wound edge cannot reach normal strength any sooner.

Understanding that trade-off helps the rest of recovery make sense. The shield exists because the wound is weak. The drops exist because the eye’s own defenses are limited at the surface. And the gradual clearing of vision is the visible sign of a tissue slowly returning to its precise, glassy geometry.

Who corneal repair is usually for, and who is usually asked to wait

Surgeons typically consider a corneal transplant when the cornea itself is the barrier to sight and cannot be managed with glasses, contact lenses or medication. According to Mayo Clinic and the NHS, common reasons include keratoconus, a condition in which the cornea thins and bulges into a cone shape; Fuchs’ dystrophy, in which the pump cells at the back fail and the cornea swells; scarring from infection or injury; and clouding after previous eye surgery. Traumatic repair, by contrast, is rarely elective. A full-thickness cut needs closing promptly to keep the eye sealed and to reduce infection risk.

Not everyone who qualifies goes ahead immediately. Ophthalmologists often ask people to wait, or to treat something else first, when:

• An active infection or inflammation on the eye surface has not settled, since operating into inflamed tissue raises the chance of graft failure.
• Severe dry eye or eyelid problems would leave a new graft poorly protected; these are usually optimized beforehand.
• Uncontrolled glaucoma, meaning raised pressure inside the eye, could damage a fresh graft and the optic nerve.
• Another eye condition, such as advanced macular disease, means a clear cornea would not translate into useful vision, so the balance of benefit and risk changes.
• A person cannot yet commit to the long follow-up schedule and drop routine, which is a practical rather than a moral judgment.

For the back-layer procedures, surgeons also weigh whether the front of the cornea is healthy enough to keep, since replacing less tissue usually means faster recovery. None of these are fixed rules. The treating team looks at the whole eye, the other eye, general health and daily life before proposing timing, and the decision remains theirs and yours together.

Corneal repair recovery: what the first days usually look like

Most corneal repairs are day procedures under local anesthetic with sedation, or general anesthetic for children and for some traumatic injuries. You go home with the eye padded or shielded and a set of written instructions.

The first 24 to 48 hours tend to feel grittier than painful. The NHS notes that some soreness, a scratchy sensation and watering are expected, and that the eye is often red and the eyelid puffy. Light sensitivity is common, so sunglasses indoors are not vanity. Vision through the operated eye is usually very blurry at this stage, partly from swelling, partly from the antibiotic ointment or thick drops, and partly from the shield itself.

If you had an endothelial transplant, the surgeon places an air or gas bubble inside the eye to press the thin donor layer into position. Mayo Clinic explains that people are asked to lie flat on their back for periods during the first day or two so the bubble floats up against the graft. This is one of the few times in medicine where doing nothing, face up, is the treatment.

The first follow-up visit is typically the next day. The surgeon lifts the shield, checks that the wound is sealed, that pressure inside the eye is acceptable and, for transplants, that the graft is attached. Do not be alarmed if the eye looks worse than you expected under the bright slit lamp; red, watery and swollen is the normal appearance of a healing eye, not a warning sign.

Pain that is severe, escalating or accompanied by nausea is different, and belongs in the red-flag section below. For everything else in the first week, the job is simple and repetitive: shield on when instructed, drops on time, hands off the eye.

Why the eye shield after corneal surgery matters more than it looks

The shield is a perforated plastic cup taped over the closed eye, and its purpose is mechanical rather than medical. A freshly sutured cornea is held together by stitches and by the eye’s internal pressure pressing outward on the wound edges. Until the tissue starts to knit, any inward force is a threat.

Consider what a sleeping person does to their face without knowing it. They roll onto a pillow, rub an itch with a knuckle, or fling an arm across the eyes. Any of these can press on a corneal wound with far more force than the sutures are designed to resist. Surgeons who repair traumatic lacerations sometimes see a second injury caused not by the original accident but by an unconscious rub a few nights later. The shield turns those movements into harmless taps on plastic.

Most instructions follow a pattern, though your surgeon’s version is the one to follow:

• Wear the shield continuously for the first day, until the first check.
• Wear it at night, and often for daytime naps, for a period the surgeon specifies; Cleveland Clinic and Mayo Clinic both describe several weeks of night-time shielding as common after transplant.
• During the day, glasses or sunglasses act as a lighter barrier against dust, wind and accidental contact.
• Tape the shield to cheek and brow, not to the eyelid, and clean it with soap and water daily.

People sometimes stop early because the shield is uncomfortable or because the eye “feels fine.” Feeling fine is not the same as being strong; the cornea has few pain fibers deep in the stroma, so a wound can be fragile without hurting. If the tape irritates your skin, ask the team about hypoallergenic tape or a shield that fits over a glasses frame rather than abandoning it.

The drop routine: what each class of eye drop is actually doing

The chart of drops can look intimidating, but it usually contains just two or three classes of medicine, each with a distinct job. Your prescribing clinician decides which ones, how often and for how long; what follows explains the reasoning, not a schedule.

Antibiotic drops are used for a short period after surgery to lower the risk of bacterial infection while the surface epithelium seals over. The cornea has limited immune defenses, and an infection in a fresh graft or repair is one of the most serious early complications, so these drops are treated as non-negotiable in the first days.

Corticosteroid drops are the workhorse of transplant recovery. They suppress inflammation, and in a graft they also dampen the immune system’s ability to recognize the donor tissue as foreign. Mayo Clinic notes that steroid drops are commonly continued for months, and in some people at low frequency indefinitely, because rejection can occur years after surgery. The dose is usually stepped down slowly rather than stopped, and only the treating team should make those changes.

Lubricating drops, sometimes called artificial tears, keep the surface moist. A newly operated cornea has reduced sensation, which means you may blink less and your tear film may thin. Preservative-free formulations are often suggested when drops are used many times a day.

Some people also receive drops that lower eye pressure, since steroids can raise pressure in susceptible eyes, or dilating drops for comfort in the first days.

A few practical habits make the routine work. Wash hands first. Tilt the head back, pull down the lower lid and drop into the pocket it forms, without touching the bottle tip to the eye. Wait several minutes between different bottles so one does not wash out the other. Close the eye gently rather than squeezing. And tell the team about missed doses honestly; they can only plan around what actually happened.

How long to use eye drops after corneal transplant?

This is the question people ask most, and the honest answer is that it depends on the type of repair, how the eye is behaving and the surgeon’s judgment at each visit. Still, the broad shape of the timeline is fairly consistent across major sources.

Antibiotic drops are typically the shortest course, often finished within the first couple of weeks once the epithelium has healed. Lubricants can be used for as long as the eye feels dry, which for many people is months.

Steroid drops follow a tapering pattern. In the early weeks they are used frequently, then the frequency is reduced step by step as inflammation settles. The NHS describes steroid drops continuing for months after transplant, and Mayo Clinic notes that some people stay on a low-frequency maintenance drop long term to reduce rejection risk. For full-thickness grafts, the taper tends to be longer than for back-layer grafts, because more foreign tissue is present and the wound takes longer to stabilize.

Traumatic repairs without donor tissue usually need steroids for a shorter period, since there is no graft to protect, although scarring and inflammation still have to be controlled.

Drop class	Main purpose	Typical duration pattern
Antibiotic	Lower infection risk while surface heals	Days to a couple of weeks
Corticosteroid	Control inflammation; reduce graft rejection	Months, tapered; sometimes long-term low frequency
Lubricant	Protect a dry, less sensitive surface	As needed, often months
Pressure-lowering	Counter steroid-related pressure rise if it occurs	Only if pressure rises; duration set by clinician

Two cautions. Never stop a steroid drop on your own because the eye looks quiet; rejection episodes often begin precisely when protection lapses. And never restart or increase a drop from an old bottle because the eye feels irritated. Contact the team instead, since irritation, infection and rejection can feel similar from the inside and need different responses.

Why vision clears gradually rather than all at once

People often expect a lens-replacement style result, where cataract surgery can bring sharp vision within days. Corneal repair is a different biology, and the slow clearing has several layers.

Swelling is the first. Surgical handling leaves the cornea waterlogged, and until the pump cells at the back regain their rhythm, the tissue stays hazy. For a back-layer transplant, the donor cells need days to weeks to settle in and begin dehydrating the cornea; Cleveland Clinic notes that vision after these procedures can improve over a few weeks to months.

Surface healing is the second. The epithelium regrows across the wound within days, but its new cells are irregular at first, like fresh paving before it is rolled flat. A smooth surface is what gives a crisp image, and smoothing takes time.

Sutures are the third and often the biggest factor in full-thickness grafts. Stitches placed around a circular graft pull unevenly, and this creates astigmatism, an optical distortion in which the cornea is more curved in one direction than another. Mayo Clinic explains that vision may keep changing until the sutures are removed, which can be many months after surgery, and that full visual recovery can take up to a year or longer. The NHS gives up to 18 months for the final result after a full-thickness transplant.

Finally, the brain adapts. When one eye has been blurry for years, the visual system has learned to lean on the other. As the operated eye clears, the two images have to be re-merged, and some people notice fluctuating focus or mild double vision for a while.

Because of all this, glasses prescribed too early would be wrong within weeks. Most surgeons wait until the cornea has stabilized before measuring for spectacles or contact lenses. The frustration of the in-between period is real, but it is the expected shape of recovery, not a sign that something failed.

Corneal transplant recovery time by procedure type

Not all corneal repairs recover on the same clock. The more tissue replaced and the more sutures used, the longer the road. The ranges below are drawn from patient information published by Mayo Clinic, the NHS and Cleveland Clinic; individual timelines vary, and only your surgeon can say where you sit.

Procedure	What is replaced or repaired	Sutures	Typical time to stable vision
Penetrating keratoplasty (full-thickness graft)	Entire central cornea	Many, often in place for a year or more	Up to 12–18 months
Deep anterior lamellar keratoplasty (DALK)	Front and middle layers; own pump cells kept	Many, similar to full-thickness	Often several months to a year
Endothelial keratoplasty (DSAEK, DMEK)	Back pump-cell layer only	Few or none; gas bubble holds graft	Weeks to a few months
Traumatic laceration repair	Closure of a cut in the person’s own cornea	Depends on wound size	Highly variable; depends on scar position and other injuries

A few points stand out. Endothelial procedures recover fastest largely because they avoid a large sutured wound, and because the person’s own front cornea, with its established nerve supply and surface, stays in place. That speed is one reason surgeons favor them when the disease is limited to the back layer, as in Fuchs’ dystrophy.

DALK keeps the person’s own endothelium, which lowers the lifelong risk of the most serious form of rejection, but the front surface still needs sutures, so the visual timeline resembles a full-thickness graft.

Traumatic repairs are the least predictable. A small, peripheral cut closed cleanly may leave excellent vision; a central laceration with a scar in the line of sight, or damage to the lens or retina behind it, may need further procedures. Surgeons often describe the first repair after trauma as “restoring the eye’s structure,” with visual rehabilitation planned separately once healing shows what is possible.

Stitches, astigmatism and the question of new glasses

Corneal sutures are made of nylon thinner than a strand of hair, and they are usually buried so you cannot feel them. Their removal is one of the pivot points of recovery, so it helps to understand the logic.

Early on, sutures hold the wound together. Over months, scar tissue takes over that role, and the stitches become optional. Because they pull unevenly on the graft, they also shape its curvature, and adjusting them is a tool the surgeon can use. Mayo Clinic describes selective removal or loosening of individual sutures to fine-tune astigmatism as the cornea stabilizes. This is done at the slit lamp with anesthetic drops and usually takes minutes.

The NHS notes that stitches after a full-thickness transplant are commonly left for around a year, sometimes longer, although some are removed earlier if they loosen or irritate. A loose suture matters: it can trap bacteria and cause infection, so a sudden foreign-body sensation weeks or months after surgery should be reported rather than tolerated.

Glasses follow the same timeline. Measuring for spectacles while sutures are still altering the curve produces a prescription that will not fit for long. Most teams wait until refraction has been steady across two or more visits. Even then, a transplanted cornea may leave more astigmatism than glasses can fully correct, and rigid or specialty contact lenses are sometimes suggested as the better optical solution. That is a normal part of the pathway, not a failure of the surgery.

Some people find the wait for glasses the hardest part psychologically, because it is the point where the operation is over yet daily life is still blurred on one side. Interim options, such as a temporary lens for the other eye or simply a balance lens to reduce discomfort, are worth raising with the team.

Corneal graft rejection signs, and how they differ from ordinary irritation

Rejection is the word most people fear after a transplant, so it deserves a precise explanation. Rejection is the immune system recognizing donor tissue as foreign and attacking it. Because the cornea has no blood vessels, it is relatively shielded from immune surveillance compared with a kidney or heart, which is why corneal grafts are often performed without tissue matching. Even so, rejection episodes do occur; Mayo Clinic puts the figure at roughly 10% of cornea transplants, and the risk is higher when the recipient’s cornea has blood vessels growing into it from previous disease.

Two things about rejection are reassuring. It is usually reversible if treated early, typically with more intensive steroid drops prescribed by the treating team. And it rarely happens overnight; it develops over days, which gives a window to act.

The signs are summarized by the memory aid RSVP, used in patient literature from Mayo Clinic and others:

• Redness of the eye, especially if new or worsening.
• Sensitivity to light that is greater than your recent baseline.
• Vision that becomes blurrier than it was a day or two before.
• Pain or aching in or around the eye.

Ordinary irritation from dryness or a loose suture tends to feel gritty and superficial, improves with lubricating drops, and does not steadily blur vision. Rejection tends to feel deeper, comes with a drop in clarity that does not lift after blinking or lubrication, and often wakes you to light sensitivity you did not have yesterday.

Since these overlap, the safe rule is simple: any new combination of redness, light sensitivity, blurring or pain in a transplanted eye is a same-day call, not a wait-and-see. Teams would far rather examine a false alarm than treat a graft a week late. Rejection risk persists for years, so this rule outlives the drop routine.

Everyday life during corneal repair recovery: sleep, washing, screens and exercise

The practical questions arrive on day two, usually in the shower. Guidance varies with the operation, so treat the following as the common pattern described by the NHS and Mayo Clinic, and defer to your own team’s leaflet.

Water and soap are the first concern. Keeping the eye closed while washing hair, or tilting the head back, is usually enough. Swimming is generally off the table for a period; the NHS advises avoiding swimming for at least a month after transplant and until the team confirms the wound is sealed, since pools and open water carry organisms the fresh surface cannot fight.

Sleep is where the shield does its work, as discussed above. Sleeping on the non-operated side, or on your back, reduces accidental pressure. After an endothelial graft, the surgeon may ask for face-up positioning for the first day or two.

Screens, reading and television are safe for the eye; they cannot damage a graft. They are, however, tiring, because the operated eye is blurry and the two eyes are not yet cooperating. Short sessions with breaks are more comfortable, and there is no medical reason to avoid them.

Bending, lifting and exercise carry a different risk: a strain raises pressure inside the eye and can stress a wound. Gentle walking is encouraged from the first days. Mayo Clinic advises avoiding strenuous activity and heavy lifting for a few weeks, and contact sports for longer, often with protective eyewear indefinitely after a full-thickness graft because the wound never regains full original strength.

Driving depends on the vision in the other eye meeting legal standards and on your comfort with depth perception; ask before assuming. Returning to desk work is often possible within a week or two, while dusty or physically demanding jobs need a longer, individually agreed gap. Eye makeup is usually paused until the team says the surface is sealed.

What people often get wrong about corneal repair recovery

Recovery myths spread quickly in waiting rooms and online forums, and several of them can cause real harm.

“If the eye feels fine, the shield and drops can stop.” The cornea has few pain receptors in its deeper layers, so comfort is a poor guide to wound strength or to simmering inflammation. Rejection episodes and pressure rises are frequently painless early on. The schedule exists because sensation is unreliable.

“Blurry vision at three months means the graft failed.” As the NHS and Mayo Clinic both note, vision after a full-thickness transplant can take a year or more to stabilize, and it often fluctuates as sutures are adjusted. Failure is diagnosed by the surgeon at the slit lamp, not by how the world looks from the sofa.

“Donor tissue has to match my blood type or my eye color.” Corneal grafts are usually not tissue-matched, because the cornea’s lack of blood vessels gives it immune privilege. Eye color comes from the iris behind the cornea and is unaffected.

“Once the drops are finished, rejection is no longer a risk.” Rejection can occur years later, particularly after illness, another eye procedure or a lapse in maintenance drops. The RSVP warning signs stay relevant for life.

“Reading or screens will strain the graft.” Using the eye does not harm it. Rubbing it does.

“A transplanted cornea is as strong as the original.” A healed full-thickness wound remains weaker than intact tissue, which is why lifelong eye protection during sports and hazardous work is standard advice.

“Corneal repair fixes the whole eye.” The cornea is the window; the lens, retina and optic nerve behind it also have to be healthy for clear sight. Surgeons assess this beforehand and explain what a clear cornea can realistically deliver in each individual eye.

Questions to ask your care team before and after corneal repair

Good questions make follow-up visits shorter and safer, because they surface the details that written leaflets cannot personalize. Consider bringing a short list, and a companion to help remember the answers.

• Which type of repair did I have, and how does that change my expected timeline for vision and for suture removal?
• How long should I wear the shield at night, and what should I do if the tape irritates my skin?
• Which drops am I using, what is each one for, and in what order should I use them when two are due at the same time?
• What should I do if I miss a dose, or if a bottle runs out before my next appointment?
• Do I need to lie in a particular position, and for how long?
• When can I wash my hair normally, swim, return to work, drive, and resume exercise?
• What does a rejection episode look like for my type of graft, and who do I call outside clinic hours?
• Will my eye pressure be checked, and what symptoms of raised pressure should I watch for?
• When will I be measured for glasses or contact lenses, and is specialty lens fitting likely?
• Are there activities I should avoid permanently, such as contact sports without eye protection?
• If the graft were to fail, what would the options be?
• How do my other conditions, such as diabetes, glaucoma or dry eye, affect this recovery?

Write down the answers in your own words and read them back; misunderstandings about drop order and shield duration are among the most common reasons for avoidable problems. If two members of the team give slightly different advice, ask which applies to you rather than choosing the more convenient version.

Finally, ask how to reach the team quickly. Many units provide a direct line for post-operative patients, and knowing the number before you need it removes a real barrier to calling early.

When to call your doctor: red-flag signs after corneal repair

Most of recovery is uneventful, but a small number of problems need attention within hours, not days. Contact your eye surgery team the same day, or attend an emergency department if you cannot reach them, for any of the following, which are drawn from patient guidance published by Mayo Clinic, the NHS and MedlinePlus:

• Sudden or worsening loss of vision in the operated eye, especially if it was clearer the day before.
• Increasing pain, or pain that is not eased by the comfort measures you were given; severe eye pain with nausea or vomiting can signal a sharp rise in eye pressure.
• New or increasing redness, particularly combined with light sensitivity or blurring, which together form the RSVP pattern of possible graft rejection.
• Thick, yellow or green discharge, or the eyelids stuck shut in the morning with more than the expected light crusting.
• Any blow, poke or rub to the eye, even if it does not hurt, because a wound can open without pain.
• A sudden feeling of something in the eye weeks or months after surgery, which may be a loose or broken suture.
• A new shower of floating spots, flashes of light or a curtain across part of the vision, which can indicate a retinal problem behind the cornea.
• Fever with a painful, red eye.

Call sooner rather than later if you are unsure. Post-operative teams expect these calls and would rather see a quiet eye than miss an infection, a pressure spike or an early rejection, all of which are far easier to manage in the first day or two than after a week.

Do not put any drops into the eye beyond your prescribed routine while waiting to be seen, do not remove a suture yourself, and keep the shield on if there has been any impact. Bring your drop bottles and your written schedule to the appointment; they tell the team more than memory can.

Frequently asked questions

How long does corneal repair recovery take overall?

Typically weeks to many months, depending on the procedure. Back-layer transplants often stabilize within weeks to a few months, while full-thickness grafts can take up to a year or longer for final vision, with the NHS quoting up to 18 months. Traumatic repairs vary widely. Your surgeon’s assessment at each visit is the only reliable guide to your own timeline.

How long do I wear the eye shield after corneal surgery?

Continuously until the first post-operative check, then usually at night and during naps for a period your surgeon specifies, commonly several weeks after transplant. The shield prevents accidental rubbing or pressure on a wound that cannot yet resist force. Follow your own team’s instruction rather than a general figure, and keep using it even when the eye feels comfortable.

How long to use eye drops after corneal transplant?

Antibiotic drops are usually brief, often finished within a couple of weeks. Steroid drops are tapered over months and, in some people, continued at low frequency long term to reduce rejection risk. Lubricants are used as needed, often for months. Only the prescribing clinician should change the schedule; stopping steroids early is a common trigger for rejection episodes.

Why is my vision still blurry weeks after a corneal transplant?

Because the cornea is still swollen, the surface is still smoothing, and sutures are still shaping its curvature. Mayo Clinic notes vision may keep changing until stitches are removed, which can be many months after surgery. Persistent blur at this stage is expected, not a sign of failure, but any sudden worsening should be reported the same day.

What are the corneal graft rejection signs I should watch for?

Redness, sensitivity to light, blurred vision and pain, remembered as RSVP. Rejection usually develops over days, and Mayo Clinic reports it affects roughly 10% of transplants. It is often reversible if treated early with intensified steroid drops prescribed by the team, so any new combination of these symptoms in a transplanted eye warrants a same-day call.

What is the corneal transplant recovery time for DMEK compared with a full-thickness graft?

DMEK and DSAEK replace only the back layer, use few or no sutures, and commonly clear within weeks to a few months. Full-thickness penetrating keratoplasty involves a large sutured wound and can take 12–18 months to stabilize. The trade-off is that endothelial procedures suit only conditions confined to the back layer, such as Fuchs’ dystrophy.

Can I use screens, read or watch television during recovery?

Yes. Using the eye does not damage a graft or a repaired cornea; only pressure and rubbing do. Screens may feel tiring because the operated eye is blurry and the two eyes are not yet working together, so shorter sessions with breaks are more comfortable. There is no medical requirement to rest the eye from visual tasks.

When can I swim, exercise or lift heavy objects after corneal repair?

Gentle walking is usually encouraged from the first days. Strenuous exercise and heavy lifting are commonly paused for a few weeks because straining raises eye pressure. The NHS advises no swimming for at least a month and until the wound is confirmed sealed. Contact sports generally need protective eyewear long term after full-thickness surgery. Ask your team for your specific dates.

When will I get glasses after a corneal transplant?

Usually only after the cornea has stabilized, often after sutures have been adjusted or removed, because the prescription keeps shifting until then. This can be many months after surgery. Some people are better served by rigid or specialty contact lenses, since a transplanted cornea may leave astigmatism that glasses cannot fully correct. Interim options for comfort can be discussed.

Does a repaired or transplanted cornea ever return to full strength?

Not entirely. A healed full-thickness wound remains weaker than intact corneal tissue, which is why surgeons advise permanent eye protection for sports and hazardous work and why a blow to the eye years later should still be assessed promptly. Endothelial grafts, which avoid a large sutured wound, leave the front cornea’s original strength largely intact.
