Vitrectomy

What is a vitrectomy?

A vitrectomy is a microsurgical operation in which the surgeon removes some or all of the vitreous, the clear gel that fills the inside of the eye, in order to reach and repair the retina and macula at the back of the eye. It is used to treat retinal detachment, macular holes, epiretinal membranes, vitreous haemorrhage, complications of diabetic eye disease and eye injuries. The operation is performed by a vitreoretinal surgeon — an ophthalmologist with advanced training in diseases of the retina, macula and vitreous.

Many people first hear the word after a sudden change in vision: new floaters, flashes of light, a dark shadow or curtain across part of the visual field, blurred central sight, or vision that seems blocked by blood or scar tissue inside the eye. Others come to the decision more gradually, after months of distorted reading vision or reduced sharpness from a macular condition. Either way, the questions tend to be the same. Will it hurt? What happens if I wait? How long does recovery take? And what can the operation realistically achieve?

Patients researching vitrectomy in Turkey usually add a further layer of practical questions about travel timing, follow-up visits and how a care pathway works away from home. This page answers the clinical questions first, then the practical ones, because the medicine should drive the plan — not the logistics. Vitrectomy is not one single operation performed the same way for everyone. It is a highly specialised category of eye surgery adapted to the exact condition being treated, which is why understanding your own diagnosis matters more than the name of the procedure.

It also helps to understand vitrectomy less as a single treatment and more as a surgical platform. In one patient, the operation is focused on clearing haemorrhage that blocks vision. In another, it is used to peel a fine membrane from the surface of the macula. In someone with a detached retina, it becomes part of a more complex repair that includes laser treatment and an internal gas or oil support. The steps at the start are similar; what happens once the surgeon is inside the eye depends entirely on the disease.

What is the vitreous?

The vitreous is the transparent, jelly-like substance that fills the central cavity of the eye, sitting between the lens at the front and the retina at the back. In a healthy young eye it is clear and firmly structured, helping to maintain the eye’s shape while letting light pass through undisturbed to the retina. With age, and in certain diseases, it changes. It can liquefy, shrink and pull on the retina; it can fill with blood from fragile or damaged vessels; and it can act as a scaffold for scar tissue that drags on delicate retinal layers. When the vitreous itself has become part of the problem — or when it simply stands between the surgeon and tissue that needs repair — removing it is often the logical first step. The eye does not need the vitreous to function; after surgery, the space fills with fluid the eye produces naturally.

Pars plana vitrectomy meaning

Pars plana vitrectomy means removal of the vitreous through the pars plana, a narrow band in the wall of the eye just behind the coloured iris. This zone matters because it allows instruments to enter the eye without passing through the retina or the lens, which is why it is the standard route for modern vitreoretinal surgery. When your surgeon or your report refers to a pars plana vitrectomy, or simply a PPV, this is the same operation described throughout this page — the name describes the entry route, not a different procedure.

Through these pars plana openings, which are measured in fractions of a millimetre, the surgeon introduces the fine instruments used for the entire operation. The small-incision approach used today often allows the openings to seal on their own, which can support recovery and reduce disruption to surrounding tissue.

Who may need vitrectomy surgery?

Vitrectomy surgery is considered when symptoms and examination findings point to a problem inside the eye that cannot be managed adequately with observation, medication or office-based treatment alone. Some patients need urgent surgery — particularly when the retina is detached or at immediate risk. Others reach the operation after a period of careful monitoring, when the degree of visual distortion, bleeding, traction or structural damage makes surgery the most appropriate next step. The decision always sits on a spectrum from emergency to elective, and knowing where your case sits is one of the most useful things a retinal specialist can tell you.

Common symptoms that lead to evaluation include:

• Sudden or progressive blurred vision
• Floaters, especially if dense or accompanied by bleeding
• Flashes of light
• A shadow, curtain or missing area in the visual field
• Distorted central vision, such as straight lines appearing bent
• Difficulty reading or recognising faces
• Vision loss after an eye injury

Diagnosis starts with a detailed ophthalmic examination. The doctor reviews your symptoms, medical history, prior eye procedures and conditions such as diabetes or severe short-sightedness that increase retinal risk. The eye is then examined with a dilated retinal evaluation to assess the vitreous, retina and macula directly.

Imaging plays a central role in identifying the precise problem and planning treatment. Depending on the case, this may include optical imaging of the macula to detect traction, holes, swelling or membranes; ultrasound when bleeding obscures the view into the eye; retinal photography; and other specialised tests that clarify the cause of visual loss. If the problem relates to diabetes or vascular disease, a broader medical review may form part of the planning, because the health of the whole body affects how the eye heals.

Patient situations that commonly lead to vitrectomy include persistent vitreous haemorrhage that does not clear adequately, retinal detachment, macular hole, an epiretinal membrane causing distortion, complications of diabetic eye disease, retained lens material after cataract surgery, eye trauma, and certain infections or inflammatory conditions inside the eye. The decision is never based on a scan alone. It rests on symptoms, visual function, structural findings, urgency, and an honest assessment of whether surgery can meaningfully help.

Conditions a vitrectomy can treat

Vitrectomy is used across a range of retinal and vitreous disorders. The most common indications include:

• Retinal detachment: when the retina separates from the back wall of the eye, urgent repair may be needed to prevent permanent vision loss. Vitrectomy lets the surgeon relieve traction, reattach the retina and secure it in place.
• Macular hole: a small opening in the central retina causes blurred and distorted central vision. Vitrectomy is commonly used to relieve traction and support closure of the hole.
• Epiretinal membrane: also called macular pucker, this is a layer of scar-like tissue on the macula that wrinkles the retinal surface and distorts vision. The membrane can be peeled away during surgery.
• Vitreous haemorrhage: bleeding into the vitreous blocks light from reaching the retina, causing clouded or darkened vision. Surgery is considered when blood does not clear on its own, or when the retina underneath also needs treatment.
• Diabetic retinopathy complications: advanced diabetic eye disease can produce recurrent bleeding, traction on the retina, scar tissue and tractional retinal detachment, all of which may need surgical management.
• Retinal tears with complex vitreous traction: in selected cases, vitrectomy is used when a tear is difficult to manage by less invasive methods, or when associated changes inside the eye raise the risk of progression.
• Dislocated or retained material inside the eye: including lens fragments after cataract surgery or a dislocated intraocular lens in carefully selected cases.
• Eye trauma: penetrating injury, internal bleeding, retinal damage or foreign material inside the eye may require vitrectomy as part of the repair.
• Certain infections or severe inflammation: in some patients, surgery removes infected or inflammatory material and allows medication to be delivered inside the eye.

Not every patient with these diagnoses needs immediate surgery, and not every retinal problem is treated with vitrectomy. Some conditions respond to office-based retinal treatments such as laser or injections. The key question is always whether removing the vitreous and operating inside the eye is the best way to protect or improve vision in your specific case.

Vitrectomy in retinal detachment

Vitrectomy in retinal detachment is often the core of the repair rather than a preliminary step. Once the vitreous has been removed and the traction pulling on the retina released, the surgeon flattens the detached retina, drains the fluid that has collected beneath it, and applies laser treatment around retinal tears to seal them. A temporary internal support — usually a gas bubble, sometimes silicone oil — is then placed to hold the retina against the wall of the eye while the laser scars mature and the tissue heals. The choice between gas and oil depends on the extent and complexity of the detachment, whether the macula is involved, and factors such as previous surgery or the need to travel. Because a detached retina can progress within days and involve the macula, this is one of the situations in which timing genuinely matters.

Is a vitrectomy the same as retina operation surgery?

Retina operation surgery is a broad label that covers any procedure performed on or around the retina; vitrectomy is one of the most common forms, but not the only one. Some retinal problems are treated with laser alone, some with scleral buckling from the outside of the eye, some with injections, and some with a combination of approaches. If you have been given a diagnosis rather than a procedure name, it is worth understanding the full range of retina surgery options before assuming vitrectomy is the only path — and equally worth understanding why your surgeon has recommended it if they have.

How a vitrectomy is performed

Before surgery, you undergo a detailed retinal assessment and a preoperative review of your overall health. The ophthalmology team confirms the diagnosis, documents your current visual function and explains the specific objective of your operation. If a gas bubble or silicone oil may be used, this is discussed in advance, because it affects postoperative positioning, travel timing and activity restrictions. Your medications are reviewed carefully by the team — including blood thinners, diabetes treatments and anything that may influence anaesthesia or healing — and any adjustments are decided by the treating doctors, not left to guesswork.

The operation usually takes place under local anaesthesia with sedation, or under general anaesthesia, depending on the complexity of the case, your comfort, age and medical factors. The eye is cleaned thoroughly, sterile drapes are placed, and a small device holds the eyelids gently open so you do not need to worry about blinking.

The main steps follow a consistent sequence:

1. The surgeon makes very small openings in the sclera, the white outer wall of the eye, at the pars plana.
2. Through these ports, three fine lines are introduced: one maintains the eye’s internal pressure with sterile fluid, one provides illumination so the retina can be seen clearly, and one carries the working instruments.
3. The vitreous gel is removed in a controlled manner using a precision cutting device designed for intraocular surgery.
4. Blood or debris obscuring the retina is cleared to restore visibility.
5. The underlying problem is treated: membranes or scar tissue may be peeled from the retinal surface with delicate forceps; in a macular hole repair, fine internal layers near the macula may be peeled to relieve traction and improve the chance of closure.
6. Laser treatment may be applied inside the eye to seal retinal tears or treat diseased tissue.
7. If needed, the eye is filled with a temporary support — balanced fluid, a gas bubble or silicone oil — to hold the retina in position while it heals.
8. The small openings either self-seal or are closed with tiny sutures; protective medication may be placed, and the eye is covered with a patch or shield.

The technology involved exists to solve one problem: operating safely in a space that is extremely small and extremely delicate. High-magnification operating microscopes and advanced visualisation systems reveal fine detail. Controlled intraoperative illumination lets the surgeon see the retina from inside the eye. Fine-gauge microsurgical tools support precise dissection and removal of tissue measured in fractions of a millimetre. Imaging before surgery — and in some settings during or after it — confirms the anatomy and guides decisions. For you as a patient, the value of all this is practical rather than promotional: clearer visualisation, more accurate repair, and an approach matched to the anatomy of your disease.

Gas placed in the eye is absorbed by the body over time, at a rate that depends on the type of gas used. Silicone oil is not absorbed; depending on the case, it may need to be removed later in a separate, planned procedure. Your surgeon will tell you before the operation which is likely in your case, because the answer changes what your recovery looks like.

Procedure time varies. A straightforward vitrectomy for a membrane or macular hole typically takes less time than surgery for trauma, severe diabetic traction or a complex retinal detachment. In general, the duration reflects the underlying diagnosis, not the word vitrectomy itself. Most patients go home the same day unless there is a specific reason for hospital observation.

Is a vitrectomy a serious operation?

Yes — it is genuine intraocular surgery on the most delicate tissue in the eye, and it deserves to be taken seriously; at the same time, it is a routine, well-established procedure for experienced vitreoretinal surgeons, performed through tiny openings, usually as day surgery. The seriousness lies less in the operation itself than in what it treats: the conditions that lead to vitrectomy can threaten sight if left unmanaged, which is often the strongest argument for surgery rather than against it. As with any operation, risks exist — including bleeding, infection, raised eye pressure, cataract progression and, in some cases, the need for further surgery — and your surgeon should walk you through the risks that apply to your specific diagnosis before you decide.

Why acting early matters

In retinal disease, timing can directly influence how much vision can be preserved. Some conditions treated with vitrectomy progress quietly over months; others change within hours or days. A retinal detachment can spread until it involves the macula, the part of the retina responsible for fine central vision. Tractional scar tissue from diabetic disease can tighten over time and distort or detach the retina. Persistent blood in the eye delays both the diagnosis and the treatment of whatever caused the bleeding in the first place.

Even when surgery is not an emergency, unnecessary delay can allow more scarring, longer-lasting macular distortion or continued damage from traction. With a macular hole or epiretinal membrane, waiting too long can make visual recovery less complete, because retinal tissue does not always return fully to its original state even after a technically successful repair. In infections or severe inflammation inside the eye, delay can be especially serious.

None of this means every patient should rush to the operating theatre. It means the diagnosis should be established promptly and the urgency graded by a retinal specialist. Once you know whether your case is emergent, urgent or elective, you are in a far stronger position to make decisions — including decisions about where to be treated and whether travel is realistic within your clinical window.

Potential benefits of vitrectomy

The benefits depend on the condition being treated, but the operation is generally performed to preserve vision, improve visual function, or create the access needed to repair the retina directly. It is worth being clear-eyed about what each of these means in practice.

Benefit	What it means for you
Removal of blood or debris from the vitreous	Clears the visual pathway so light can reach the retina, and lets the surgeon evaluate and treat whatever caused the bleeding.
Access to the retina and macula	Allows direct treatment of retinal tears, detachments, membranes, scar tissue or macular holes that cannot be corrected with drops or observation alone.
Relief of traction on delicate retinal tissue	Can reduce distortion, support retinal reattachment and help prevent ongoing structural damage inside the eye.
Preservation of vision	In many cases the primary goal is to protect remaining eyesight and reduce the risk of further loss, particularly when disease is progressing.
Potential improvement in visual quality	Some patients notice clearer, less distorted or more stable vision over time, though the degree of improvement depends on the original condition and the health of the retina before surgery.

Recovery after vitrectomy

Every eye heals at its own pace, and your diagnosis shapes your recovery more than the operation does. Vision is commonly blurred at first — because of postoperative swelling, dilating drops, a gas bubble in the eye, or simply because the retina itself is still healing. Eye drops are prescribed to reduce inflammation and lower infection risk. Some patients must maintain a specific head position for a period of time, particularly after macular hole repair or certain detachment repairs where the gas bubble needs to press against the treated area. The following timeline reflects what many patients experience after vitrectomy.

Time period	What patients can expect
Day 1	Blurred vision, mild irritation, watering, light sensitivity and general awareness of the eye are common. The eye may be patched initially. Instructions for drops, shielding and positioning are reviewed before you leave.
First week	Vision often remains limited, especially if a gas bubble is present. Mild discomfort usually settles. Follow-up visits check healing, eye pressure, inflammation and retinal status.
First month	Many patients gradually resume routine daily activities as advised. Visual recovery may become more noticeable, although this depends heavily on the diagnosis and whether gas or oil was used.
Longer term	Vision may continue to improve over weeks to months. Some patients need further monitoring, additional retinal treatment, cataract management, or a planned second procedure if silicone oil was placed.

How painful is vitrectomy recovery?

Most patients describe the recovery as uncomfortable rather than severely painful: a gritty, scratchy sensation, mild aching, watering and light sensitivity are typical for several days, and these usually settle as the surface of the eye heals. The operation itself is performed under anaesthesia, so you should not feel the surgery as it happens. Marked or worsening pain is not the expected course after vitrectomy, which is one reason follow-up visits are scheduled closely in the first days and weeks — they let the surgeon confirm that eye pressure, inflammation and healing are all behaving as they should.

What not to do after a vitrectomy

The restrictions after a vitrectomy exist to protect the healing retina and, where relevant, to keep a gas bubble or oil doing its job. Your own surgeon’s instructions take priority over any general list, but the common ones are:

• Do not fly or travel to high altitude while a gas bubble remains in the eye — pressure changes can be dangerous. Timing differs by gas type, so this is confirmed individually; the comparison in Flying After Eye Surgery explains why retinal procedures carry stricter flight rules than other eye operations.
• Do not rub or press on the eye, and use the protective shield as instructed, particularly while sleeping.
• Do not abandon the positioning your surgeon prescribed — face-down or side positioning is part of the treatment, not an optional extra.
• Do not lift heavy weights, strain or do vigorous exercise until cleared at follow-up.
• Do not let water, soap, dust or cosmetics get into the eye in the early healing period; swimming is off the list until your surgeon approves it.
• Do not drive until your vision and your surgeon permit it — a gas bubble alone makes driving unsafe.
• Do not have nitrous oxide anaesthesia for any other procedure while gas remains in the eye; the anaesthetic team for any future operation must know a bubble is present.

Can I sleep on my side after vitrectomy surgery?

It depends entirely on where your retinal problem was and whether a gas bubble was placed — which is why this question has no universal answer. If a bubble needs to press against a specific part of the retina, your surgeon will tell you exactly which positions achieve that and which to avoid; for some patients that means face-down positioning, for others a particular side is required, and for others side-sleeping is fine from the start. What matters is that the instruction is followed for the full period prescribed, because positioning is part of what makes the repair hold. If no tamponade was used, sleeping restrictions are usually far lighter.

What influences the outcome

The most important factor in vitrectomy outcomes is the underlying eye condition. Surgery to remove a simple non-clearing haemorrhage has a different outlook from surgery for a complex retinal detachment, advanced diabetic traction or severe trauma. The health of the retina before surgery matters greatly: if the macula has been detached, scarred or chronically distorted, the eye may heal well anatomically while visual recovery remains limited. This distinction — between anatomical success and visual result — is one of the most important things to discuss with your surgeon before the operation.

Timing is the second major factor. Earlier treatment improves the chance of preserving useful vision in many urgent retinal disorders. Diabetes, inflammation, previous eye surgery, glaucoma, high myopia and recurrent retinal disease can all affect both the complexity of the operation and the pace of recovery.

Your own part matters too. Proper use of eye drops, attending every follow-up visit and maintaining any required positioning all influence healing. Patients with an intraocular gas bubble carry specific safety responsibilities, including the flight and anaesthesia restrictions described above, for as long as the gas remains.

Finally, realistic expectations are part of a good outcome. Vitrectomy can be highly effective at correcting the structural problem inside the eye, but visual improvement is not always immediate and not always complete. In some situations, the honest value of surgery is preventing further decline rather than restoring vision to what it once was. A frank discussion of goals, risks, alternatives and expected recovery before treatment is not pessimism — it is the foundation of a decision you can stand behind.

How much does vitrectomy eye surgery cost?

There is no single price for a vitrectomy, because the operation is not a single, uniform procedure. The cost in any country reflects the underlying diagnosis and the complexity it brings: a membrane peel differs from a multi-stage trauma repair; local anaesthesia differs from general anaesthesia; gas tamponade differs from silicone oil, which may add a second, planned operation to remove the oil later. Preoperative imaging, the surgical facility, the surgeon’s time, medications and the number of follow-up visits all sit inside the real cost of care, whether or not they appear as separate lines on an estimate.

The practical advice is the same wherever you are treated: ask for a written treatment plan that states the diagnosis, the planned procedure, the type of anaesthesia, the expected tamponade, and exactly what the quoted figure includes — particularly follow-up visits and any anticipated second procedure. A quote that cannot answer those questions is not yet a quote you can compare.

Coming to Turkey for a vitrectomy: what international patients should plan

A typical international pathway begins before travel, with a review of existing eye reports, scans and medical history so that the surgical team can gauge the diagnosis, the urgency and whether travel is clinically sensible within your treatment window. On arrival, the diagnosis is confirmed with a fresh dilated examination and imaging — retinal findings can change, and no responsible surgeon operates on the basis of old scans alone. The care pathway then usually covers the preoperative assessment, the operation itself, early postoperative checks, and a clear written plan for the follow-up that will continue with an ophthalmologist at home.

The single most important planning point for retinal surgery abroad is tamponade. If a gas bubble is placed in your eye, you cannot fly until it has absorbed, and the timeframe depends on the gas used — so your return flight must be planned around the surgery, not the other way round. Silicone oil does not carry the same flight restriction, but may mean a second procedure later. Build follow-up visits into your stay, arrange a companion if positioning requirements are likely, and make sure your home ophthalmologist receives the full surgical report before you leave.

At Acibadem, care for these conditions is organised around subspecialty ophthalmology, with access to vitreoretinal expertise through dedicated retina and vitreous services, modern diagnostic pathways, and multidisciplinary support when systemic disease is part of the picture — such as diabetes, vascular disease or trauma. Complex or time-sensitive cases can be reviewed across specialist teams, which is particularly relevant for diabetic retinopathy, combined cataract and retinal disease, previous eye surgery or ocular trauma. International patient teams work in multiple languages, helping with consultations, documentation, appointment scheduling and the practical planning around treatment — because eye surgery abroad involves considerably more than the hour spent in theatre.

Is it safe to get eye surgery in Turkey?

Safety in eye surgery is determined by the surgeon’s subspecialty experience, the standards of the facility, the quality of the diagnostic work-up and the reliability of follow-up — not by the country on the map. Turkey has a large, established ophthalmology sector that treats both a substantial domestic population and international patients, and vitreoretinal surgery is a recognised subspecialty within it. The sensible questions to ask are the same you would ask anywhere: is the operation performed by a vitreoretinal surgeon rather than a general ophthalmologist; what imaging will confirm the diagnosis before surgery; how are complications managed; and how will follow-up be handled once you are home. A centre that answers those questions plainly, and is equally plain about what surgery cannot achieve in your case, is telling you something meaningful about how it works.

Moving forward after a vitrectomy recommendation

If you have been told you may need a vitrectomy, the next step is to understand exactly why. The name of the operation is only part of the story. The questions that matter are: what condition is affecting your retina or vitreous, how urgent treatment is, what the surgery is designed to accomplish, and what recovery will involve in your specific case — including whether gas or oil is likely and what that means for positioning and travel. A careful second opinion can be valuable, especially when symptoms are changing quickly or when travel for care is part of the picture.

For many patients, vitrectomy is the direct route to protecting vision, removing what blocks it and repairing retinal disease at its source. The idea of surgery inside the eye is understandably intimidating; a precise diagnosis, an experienced vitreoretinal surgeon and disciplined follow-up are what turn it into a process you can plan for and understand.
