Retinal Detachment Surgery

Introduction

If you have been told that you have a retinal detachment and need surgery, you are facing one of the few true emergencies in eye care. It is completely natural to feel anxious. The retina is the thin layer of light-sensitive tissue at the back of your eye, and when it pulls away from the supporting tissue beneath it, your sight is at risk. The good news is that modern retinal detachment surgery is highly developed, and when it is done promptly, the retina can be successfully reattached in most cases.

This article is written for people who have just been diagnosed with a retinal tear or detachment, or who have been told surgery is being planned. It explains what retinal detachment surgery is, the different surgical approaches your eye surgeon may use, how to prepare, what happens during the operation, what recovery typically looks like, and what vision results you may expect. It also covers the special role of head positioning after surgery, the risks involved, and longer-term care of your eyes.

Retinal detachment surgery is performed by an ophthalmologist with specialised training in diseases of the retina and vitreous — often called a vitreoretinal surgeon. The right choice of operation depends on the type of detachment, its location, how much of the retina has come away, and whether the central part of the retina (the macula) is still attached.

What Is Retinal Detachment Surgery?

Retinal detachment surgery is an operation to reattach the retina to the inner wall of the eye. The retina sits against a supporting layer called the retinal pigment epithelium, which provides it with oxygen and nutrients. When the retina lifts away, those nourishing connections are lost, and the retinal cells begin to die. Without treatment, this leads to permanent loss of vision in the affected area, and often to blindness in that eye.

To understand the surgery, it helps to understand the three main types of detachment, because the surgical approach depends on which type is present.

• Rhegmatogenous detachment is the most common form. It happens when a tear or hole develops in the retina and fluid from inside the eye passes through the tear, lifting the retina off its base. This often follows shrinkage of the jelly-like vitreous gel that fills the eye.
• Tractional detachment occurs when scar tissue on the retinal surface contracts and physically pulls the retina away from the wall of the eye. This is most commonly seen in advanced diabetic eye disease.
• Exudative detachment happens when fluid builds up beneath the retina without any tear, usually because of inflammation, vascular disease, or a tumour. This form is often treated by addressing the underlying cause rather than by surgery alone.

The goal of retinal detachment surgery is to close any retinal breaks, drain or absorb the fluid that has collected beneath the retina, reattach the retina against the eye wall, and reduce the risk of another detachment. Different surgical techniques achieve these goals in different ways, and surgeons sometimes combine techniques in the same operation.

Why Is Retinal Detachment Surgery Performed?

Surgery is performed because, in nearly all cases, a fully developed retinal detachment will not heal on its own. The longer the retina remains detached, the more permanent damage occurs to the light-sensing cells. Surgery is therefore aimed at preserving as much vision as possible and preventing further loss.

Your eye surgeon may recommend surgery if:

• A part of the retina has separated from the eye wall.
• You have a retinal tear with fluid already collecting beneath the retina.
• The macula — the small central area responsible for sharp, detailed vision — is threatened or has already detached.
• You have a tractional detachment caused by diabetic scar tissue that is pulling on the retina.
• A small retinal tear cannot be safely sealed by laser or freezing treatment alone.

Whether the macula is still attached at the time of surgery is one of the most important factors influencing the result. When the macula is still on (“mac-on”), surgery is usually performed as soon as practical to keep it that way. When the macula has already detached (“mac-off”), surgery is still important to reattach the retina and prevent further loss, but central vision may not return to what it was before.

Who Is a Candidate?

Most people with a fresh rhegmatogenous detachment are candidates for surgery. Your surgeon will examine your retina in detail and consider several factors before deciding which approach is most suitable. These include:

• The type of detachment (rhegmatogenous, tractional, or exudative).
• The number, size, and location of any retinal tears.
• How much of the retina is detached and whether the macula is involved.
• How long the retina has been detached.
• The clarity of the front of your eye, particularly the cornea and the lens.
• Whether you have had previous eye surgery, such as cataract surgery.
• Your ability to maintain specific head positions after surgery, which matters for some techniques.
• Your overall health and ability to tolerate the chosen type of anaesthesia.

People with conditions that make positioning difficult, who cannot travel for air, or who have certain other eye conditions may be guided towards one approach over another. The surgeon will discuss the trade-offs with you.

Alternatives to Surgery

For a fully developed retinal detachment, surgery is generally the only effective treatment. However, certain earlier stages of retinal disease are managed without an operation in the operating theatre.

Laser Photocoagulation

If you have a retinal tear but the retina has not yet detached, or there is only a very small amount of fluid around the tear, laser treatment may be enough. The laser creates a series of small burns around the tear, which scar down and seal the retina to the wall of the eye. This is usually done in the clinic in a single visit, without an incision.

Cryotherapy (Freezing Treatment)

Cryotherapy uses a freezing probe applied to the outside of the eye to create a similar scar around a retinal tear. It is used when laser is not practical — for example, when the tear is in a location difficult to reach with laser or when the view of the retina is poor.

Observation

Some retinal changes, such as long-standing flat tears or lattice degeneration without symptoms, are sometimes simply monitored. This depends on your surgeon’s judgement of the risk.

There are three main surgical techniques used to repair retinal detachment. Your surgeon may use one of them, or sometimes combine two — for example, scleral buckle with vitrectomy. Each approach has situations in which it is favoured, and the choice depends on the features of your detachment.

Pneumatic Retinopexy

Pneumatic retinopexy is the least invasive of the three approaches. It is usually done under local anaesthesia in a treatment room rather than the main operating theatre.

The surgeon injects a small bubble of expanding gas into the vitreous cavity of the eye. The gas bubble rises within the eye and pushes the detached retina back against the eye wall. With the retina in place, the surgeon then seals the retinal tear with laser or cryotherapy. As the body absorbs the gas over the following weeks, the seal holds the retina in position permanently.

Pneumatic retinopexy is generally considered for selected cases where there is a single tear or a small group of tears in the upper part of the retina, the eye has not had previous major surgery, and the patient can reliably maintain a specific head position for several days. It avoids cuts to the eye wall, but it depends heavily on the patient’s ability to follow positioning instructions.

Scleral Buckle Surgery

Scleral buckle surgery is a long-established technique. It is usually performed in the operating theatre under local or general anaesthesia.

The surgeon places a thin band of silicone — the buckle — around the outside of the eye, beneath the conjunctiva (the thin transparent membrane on the surface of the eye). The buckle gently indents the wall of the eye inwards, bringing it closer to the detached retina. This relieves the pulling forces on the retinal tear and helps the retina settle back into place. The tear itself is then sealed with cryotherapy or laser. Sometimes fluid trapped beneath the retina is drained through a tiny opening in the eye wall.

The silicone band stays in place permanently. It is not visible from the outside once the eye has healed. Scleral buckle is often favoured in younger patients whose vitreous gel is still firmly attached, in detachments with tears in the lower part of the retina, and in eyes with their natural lens still in place.

Pars Plana Vitrectomy

Pars plana vitrectomy is now the most widely performed retinal detachment operation in many centres, particularly for complex or large detachments. It is performed in the operating theatre, usually under local anaesthesia with sedation, or sometimes under general anaesthesia.

The surgeon makes three very small openings in the white of the eye (the sclera), in an area called the pars plana that lies safely behind the lens and in front of the retina. Through these openings, fine instruments and a light source are inserted into the eye. The vitreous gel is carefully removed, which releases any traction on the retina. The surgeon then drains the fluid from beneath the retina, flattens the retina back against the wall of the eye, and seals all the retinal tears with laser.

To hold the retina in place while the laser scars form, the surgeon fills the eye with one of the following:

• A long-acting gas bubble, which the body absorbs over a few weeks. This is the most common choice.
• Silicone oil, which stays in the eye for several months. Silicone oil is generally used for more complex detachments, recurrent detachments, or when the patient cannot maintain head positioning or travel by air. A second, smaller operation is needed later to remove the oil.

Vitrectomy can be combined with a scleral buckle in selected cases. The operation typically takes between one and two hours.

Preparing for Retinal Detachment Surgery

Because retinal detachment is time-sensitive, preparation often happens quickly — sometimes within hours of diagnosis. Even so, certain steps will be taken before surgery.

• Detailed eye examination. Your surgeon will perform a dilated examination using a specialised lens to map the location and extent of any tears and the detachment. Optical coherence tomography (OCT) and ultrasound of the eye may be used, particularly if there is bleeding or another reason the retina is hard to see.
• Anaesthetic assessment. You will be asked about your medical history, allergies, medications, and any previous reactions to anaesthesia. Blood thinners may need to be adjusted under the guidance of the doctor who prescribed them.
• Fasting. If you are having sedation or general anaesthesia, you will be asked not to eat or drink for a set number of hours before surgery.
• Eye drops. Drops may be started to dilate the pupil and to reduce the risk of infection.
• Practical planning. Because vision in the operated eye will be reduced for some time and head positioning may be needed, it helps to arrange for someone to accompany you home and to assist with daily tasks for the first days after surgery.

Your surgeon will explain which surgical approach is planned, why it has been chosen for your particular situation, and what positioning will be required afterwards.

What Happens During Surgery

The exact steps depend on the chosen technique, but a few elements are common to all retinal detachment operations.

You will be positioned lying down on the operating table, with the area around the eye cleaned and draped. The eye is held open with a small instrument so you do not need to worry about blinking. Local anaesthesia is the most common choice; you will not see the operation, and the eye will feel numb. If sedation is given, you will feel relaxed and may drift off but typically remain rousable. Under general anaesthesia, you will be fully asleep.

During pneumatic retinopexy, the surgeon performs a careful injection of gas through a single small puncture, then applies laser or cryotherapy to seal the tear. The whole procedure usually takes well under an hour.

During scleral buckle surgery, the surgeon works on the outside of the eye, placing the silicone band, sealing the tear with cold treatment or laser, and sometimes draining subretinal fluid. The conjunctiva is then closed with fine dissolvable stitches.

During pars plana vitrectomy, the surgeon works through three tiny ports in the wall of the eye. The vitreous gel is removed, the retina is examined in detail, fluid is drained, tears are sealed, and the eye is filled with gas or silicone oil. The ports are usually self-sealing and do not need stitches.

At the end of the operation, an eye shield is placed to protect the eye, and you are taken to a recovery area before going to a ward or being discharged later that day, depending on the operation and local practice.

Recovery and Healing

Recovery from retinal detachment surgery is gradual, and patience is needed. Healing in the back of the eye is slower than in many other tissues, and improvement in vision often continues over several months.

The First Days

In the first days after surgery, the operated eye will feel uncomfortable, gritty, or sore, but severe pain is unusual. The eye will look red, and the lids may be swollen. Vision will be blurry, and if a gas bubble has been placed in the eye, you will see a dark, shifting line or bubble in your field of view. You will be given eye drops — usually a combination of antibiotic and anti-inflammatory drops — to use for several weeks.

Head Positioning

If your surgery involved a gas bubble or silicone oil, head positioning is one of the most important parts of recovery. The bubble floats to the highest point inside the eye, so the surgeon will ask you to position your head so that the bubble rests directly over the area where the retinal tear has been sealed. This may mean keeping your head face down, or turned to a particular side, for most of the day and night for a number of days.

Air Travel and Altitude

If your eye contains a gas bubble, you must not fly in an aeroplane, travel to high altitudes, or have certain types of anaesthesia gas until the bubble has fully absorbed. The change in atmospheric pressure can cause the bubble to expand and raise the pressure inside the eye dangerously. The bubble usually clears within two to eight weeks, depending on the type of gas used. Your surgeon will tell you when it is safe to fly again. Silicone oil does not expand with altitude, so flying is permitted with oil in place.

Timeline for Vision

Most people see a gradual improvement over weeks to months:

• In the first one to two weeks, vision is blurry and dominated by the gas bubble or by oil.
• Over four to eight weeks, vision typically stabilises as the gas absorbs and the eye settles.
• Over three to six months, further improvement in sharpness and contrast often continues.
• Final visual results may not be known for six months or longer.

Follow-up visits are an essential part of recovery. The surgeon will examine the retina, check the pressure inside the eye, and adjust drops as needed.

Activity

You will be advised to avoid heavy lifting, vigorous exercise, and rubbing the eye in the early weeks. Most people can return to light daily activities within a week or two, but reading, screen use, and driving depend on how the operated eye is recovering and whether you rely on the other eye for vision in the meantime.

Risks and Complications

Retinal detachment surgery is generally safe, but as with any operation on the eye, there are risks. Your surgeon will discuss these with you in the context of your particular situation.

• Recurrent or persistent detachment. The retina may not fully reattach, or may detach again, requiring further surgery. This is more likely in complex or long-standing detachments and in eyes that develop scar tissue (proliferative vitreoretinopathy).
• Cataract. Vitrectomy almost always accelerates cataract formation in eyes that still have their natural lens, often within a year or two. Cataract surgery may be needed later.
• Raised pressure inside the eye. This can occur in the early period after surgery, particularly with gas or silicone oil. It is usually managed with drops but occasionally needs further treatment.
• Bleeding inside the eye.
• Infection inside the eye (endophthalmitis). This is a rare but serious complication that needs urgent treatment.
• Double vision. Particularly after scleral buckle surgery, the way the eye muscles move can change, sometimes resulting in double vision that may need separate treatment.
• Refractive change. The prescription of glasses or contact lenses often changes after surgery, especially with a scleral buckle in place.
• Choroidal effusion or haemorrhage. Rare collections of fluid or blood beneath the retina that may resolve on their own or need treatment.
• Silicone oil complications. If oil is used, it may cause changes in the cornea, glaucoma, or other issues, which is why it is generally removed once the retina has stabilised.

Reported reattachment success rates vary by detachment type, technique, and complexity. In straightforward cases, the retina is successfully reattached with a single surgery in a high proportion of patients, and overall reattachment after one or more operations is achieved in the great majority. Visual recovery, however, does not always match the anatomical success. How well you see afterwards depends most strongly on whether the macula was attached at the time of surgery and how long the retina had been detached.

Life After Retinal Detachment Surgery

Once the retina has been reattached and the eye has settled, life after surgery focuses on visual rehabilitation, follow-up, and protecting both eyes for the long term.

Vision and Adaptation

If the macula was attached at the time of surgery, central vision is often preserved well, though minor changes in sharpness or contrast may remain. If the macula had detached, central vision may be permanently affected, and adapting to this is part of recovery. Some people benefit from a refraction check several months after surgery and may need a change in glasses. Magnifiers and low-vision support can help if central vision is reduced.

Follow-up Schedule

You will see your surgeon frequently in the first weeks, then less often as the eye stabilises. Long-term review is important because the other eye is also at higher risk of detachment, and an early tear in the fellow eye can usually be treated with laser before it progresses.

Watching for Warning Signs in Either Eye

It helps to know which symptoms suggest a new retinal tear or detachment, in either the operated or the fellow eye. These are:

• A sudden increase in floaters, especially a shower of dark spots.
• New flashes of light, particularly at the edge of vision.
• A shadow, curtain, or veil appearing across part of your vision.
• A sudden drop in vision.

Protecting Your Eyes

General eye care after retinal detachment surgery includes:

• Wearing protective eyewear during contact sports, high-impact activities, or work with flying debris.
• Managing diabetes, blood pressure, and other conditions that affect the retina.
• Attending the eye examinations recommended by your surgeon, and informing any future eye care professional that you have had retinal detachment surgery.
• Avoiding heavy eye rubbing.

Retinal Detachment Surgery in Children

Retinal detachment in children is much less common than in adults, but it does occur, and the causes are different. In children, retinal detachment is more often related to trauma, retinopathy of prematurity in babies born early, congenital conditions of the eye, or inherited retinal diseases such as Stickler syndrome and familial exudative vitreoretinopathy. The retina in children may have been abnormal from birth, which influences both the surgical approach and the visual outcome.

The principles of surgery are the same — sealing tears, draining subretinal fluid, and supporting the retina — but the technical challenges are greater. The vitreous gel is more firmly attached, scar tissue is more likely to develop, and children cannot reliably maintain head positioning. Surgery in children is usually performed under general anaesthesia by a vitreoretinal surgeon with experience in paediatric retinal disease.

Children who have had surgery for retinal detachment need careful long-term follow-up, both to monitor the operated eye and to detect any problems in the other eye. Vision rehabilitation, including support at school if needed, is an important part of long-term care.

Frequently Asked Questions

Is retinal detachment surgery urgent?

Yes. Once the retina has detached, the longer it remains separated from its supporting layer, the more damage occurs to the light-sensing cells. Surgery is generally performed as soon as practical. When the macula is still attached, surgeons aim to operate quickly to keep it that way. When the macula has already detached, surgery is still important but the timing window is slightly more flexible.

Will my vision fully return after surgery?

Visual recovery depends on several factors, especially whether the macula was attached at the time of surgery and how long the retina had been detached. When the macula was still attached, many people regain close to their previous vision. When the macula had detached, some loss of central sharpness or distortion often remains. Vision usually keeps improving for months after surgery.

How is retinal detachment surgery done?

It depends on the technique. Pneumatic retinopexy uses a gas bubble injected into the eye to push the retina back, combined with laser or freezing of the tear. Scleral buckle places a silicone band around the outside of the eye to support the tear from outside. Vitrectomy uses tiny instruments inside the eye to remove the vitreous gel, drain the fluid, seal the tears, and fill the eye with gas or oil. Sometimes two techniques are combined.

How long will I need to keep my head in a special position?

This depends on the location of the retinal tear and the technique used. Positioning is generally needed for several days to a week or two, often longer in the daytime and through the night for the first few days. Your surgeon will tell you exactly which position to use and for how long. Specialised cushions and equipment can help make this more comfortable.

Why can I not fly after surgery?

If a gas bubble has been placed inside your eye, the lower air pressure at altitude causes the gas to expand. This can dangerously raise the pressure inside the eye and damage vision. Flying must be avoided until the bubble has fully absorbed, which takes between two and eight weeks depending on the gas used. If silicone oil has been used instead of gas, flying is generally allowed.

Will I need cataract surgery later?

After vitrectomy, cataract development is very common in eyes that still have their natural lens, often within a year or two. Cataract surgery can be performed once the retina has stabilised and is usually a separate, planned operation. After pneumatic retinopexy or scleral buckle, cataract is less strongly accelerated.

Can the retina detach again?

Yes. A small proportion of operations need to be repeated because the retina does not fully reattach the first time or because scar tissue causes it to lift again. The other eye is also at increased risk of developing a tear or detachment over time, which is why long-term follow-up is recommended and why new flashes, floaters, or a shadow in either eye should be checked promptly.

What activities can I do during recovery?

In the early weeks, gentle daily activities are usually fine, but heavy lifting, vigorous exercise, swimming, and rubbing the eye are avoided. Driving depends on the vision in your operated eye and your other eye and is a question to discuss with your surgeon. Reading and screen use do not harm the eye but may be tiring while the eye recovers.

Is the surgery painful?

The surgery itself is not painful because the eye is numbed by local anaesthetic, often with sedation, or you are asleep under general anaesthesia. In the first days afterwards, the eye is sore, gritty, and sensitive to light, but severe pain is unusual and would be reported to the surgeon promptly.

Conclusion

Retinal detachment is one of the few true emergencies in eye care, but it is also a condition for which surgical treatment is well developed and frequently successful. The choice of surgery — pneumatic retinopexy, scleral buckle, pars plana vitrectomy, or a combination — depends on the type of detachment, the location of any tears, and individual eye factors. Each approach has the same goal: to close retinal breaks, settle the retina back against the eye wall, and protect vision.

Recovery is gradual and asks for patience, particularly around head positioning, eye drops, and the slow timeline of visual improvement. Long-term care matters too — for the operated eye, for the fellow eye, and for any underlying conditions that affect the retina. With prompt surgery, careful follow-up, and awareness of the warning signs of new tears, many people preserve useful vision and continue with normal life after retinal detachment surgery.
