An epiretinal membrane operation removes scar tissue that has formed on your retina. This scar tissue can wrinkle the macula (the central part of your retina responsible for sharp, detailed vision), causing blurred or distorted sight. The procedure, called a vitrectomy, involves removing the jelly inside your eye and carefully peeling away the membrane. Surgeons perform this operation under local anaesthetic, and it typically takes 45 minutes to an hour.
This article walks you through everything you need to know about epiretinal membrane surgery. You’ll learn when the operation is necessary, how to decide if it’s right for you, what happens during the procedure, and what recovery looks like. We’ll also cover success rates, potential risks, and typical costs. By the end, you’ll have clear, practical information to help you make an informed decision about your eye health.
Why epiretinal membrane surgery is done
Your surgeon recommends an epiretinal membrane operation when the scar tissue causes significant visual problems that interfere with your daily activities. The membrane wrinkles your macula, which leads to blurred or distorted central vision. You might struggle to read, drive, recognise faces, or perform tasks requiring fine detail. While some people develop mild membranes that cause minimal symptoms, surgery becomes necessary when vision deteriorates enough to affect your quality of life.
When symptoms affect your daily life
Surgery targets the visual distortion and blurriness that stop you from functioning normally. Straight lines may appear wavy, and you might notice your central vision becoming progressively worse over time. Your ophthalmologist will assess whether your symptoms are severe enough to warrant the procedure. Not everyone with an epiretinal membrane needs surgery. If you experience only minor distortion and can still perform daily tasks comfortably, watchful waiting might be appropriate. However, once the membrane significantly impacts your ability to read, work, or drive safely, surgery becomes the only effective treatment option to prevent further deterioration and restore visual function.
Surgery aims to remove the membrane before it causes permanent, irreversible damage to your retina.
How to decide if surgery is right for you
You need to weigh several factors before committing to an epiretinal membrane operation. Your decision should centre on how much the membrane affects your vision and whether the benefits of surgery outweigh the potential risks. Your ophthalmologist will perform tests, including optical coherence tomography (OCT) scans, to measure the membrane’s thickness and assess how much it distorts your macula. These results, combined with your reported symptoms, guide the recommendation.
Assessing your visual symptoms
Consider whether your distorted or blurred vision stops you from completing everyday tasks. Ask yourself if you struggle to read books, newspapers, or phone screens, or if driving has become difficult or unsafe. Many people tolerate mild distortion without surgery, particularly if their symptoms remain stable over time. However, if your vision continues to deteriorate or you find yourself avoiding activities you once enjoyed, surgery offers the only path to improvement. Your quality of life matters most in this decision.
Surgery becomes appropriate when visual symptoms significantly interfere with your independence and daily functioning.
Weighing the benefits against risks
Balance the potential improvement in vision against surgical risks like infection, retinal detachment, or cataract development. Most patients experience meaningful visual improvement, with studies showing around 50 per cent better vision on average after surgery. Your age, overall eye health, and whether you still have your natural lens all influence your individual risk profile. Discuss these factors openly with your surgeon to reach an informed decision that aligns with your personal circumstances and expectations.
What to expect during the operation
Your epiretinal membrane operation takes place in hospital and typically lasts 45 minutes to one hour. The surgeon performs a vitrectomy, which means removing the jelly-like vitreous from inside your eye. This creates space to access and peel away the scar tissue from your macula. You remain awake throughout the procedure, and the surgical team monitors you closely to ensure your comfort and safety.
The anaesthesia and preparation
The surgeon administers local anaesthetic to numb your eye, which takes approximately five minutes. You stay awake during the operation, but you won’t feel pain. The anaesthetic blocks sensation while allowing you to remain comfortable and alert. Because you’re conscious, you must stay completely still throughout the procedure. The surgical team will remind you of this and support you in maintaining position.
Staying still during surgery ensures the surgeon can work safely and precisely on your delicate retinal tissue.
The surgical steps
The surgeon uses microsurgical instruments (typically 23-gauge) to remove the vitreous gel through tiny incisions. These incisions are so small they require no stitches. Next, the surgeon carefully peels the epiretinal membrane from your macula’s surface, often removing the inner limiting membrane underneath to ensure complete scar tissue removal. At the end, the surgeon may inject a small air or gas bubble into your eye to support healing. You might also receive a steroid injection, which causes temporary black spots in your vision for about a week. The air bubble appears as a black wobbly line that gradually shrinks and disappears within five days.
Recovery timeline and aftercare
Your recovery from an epiretinal membrane operation requires patience, as vision improves gradually over weeks to months rather than immediately. Expect your eyesight to be worse than before surgery in the first few days. The air bubble, steroid injection (causing black dots), and swelling from membrane removal all contribute to reduced vision initially. Most people notice meaningful improvement starting around two weeks after the procedure, with vision continuing to stabilise for up to twelve months.
Positioning and immediate restrictions
Your surgeon may require you to maintain a face-down position for one to five days after surgery if gas was used. This positioning allows the gas bubble to press against your macula and support healing. You can hire specialised equipment to make this position more comfortable. Avoid heavy lifting, swimming, and strenuous exercise for the first three weeks. You can read, watch television, and walk, but these activities might feel uncomfortable while the air bubble and black dots remain present. If gas was used, you must not fly or travel to high altitudes until your surgeon confirms the bubble has completely absorbed, as pressure changes could cause dangerous increases in eye pressure.
Your surgeon will provide a medical alert bracelet warning against nitrous oxide anaesthesia while gas remains in your eye.
Vision recovery timeline
Vision recovery follows a predictable but gradual pattern. The air bubble typically disappears within five days, and the black dots from steroids resolve within a week. You’ll notice the most significant visual improvement during the first six weeks, though your eye continues healing for months afterwards. Your surgeon schedules regular follow-up appointments to monitor your progress and watch for complications. Once your macula has healed sufficiently, usually after several months, you can get new glasses prescribed to optimise your vision. Most patients report reduced distortion and clearer central vision compared to before surgery, even if the improvement seems slow initially.
Risks, success rates and surgery costs
Your epiretinal membrane operation carries potential risks, though serious complications remain rare. Understanding these risks, expected outcomes, and typical costs helps you make an informed decision about proceeding with surgery. Most patients achieve meaningful visual improvement, but you need realistic expectations about both the benefits and potential downsides of the procedure.
Common risks and complications
The most common complication involves cataract development, which affects nearly all patients who still have their natural lens. Cataracts typically develop faster after vitrectomy, often requiring additional surgery within one to two years. Retinal tears occur in a small percentage of patients during or after surgery, though your surgeon inspects carefully for these and treats them immediately with laser or freezing therapy if found. Other risks include infection (endophthalmitis), which affects roughly one in 2,000 patients, retinal detachment (approximately one in 100 cases), increased eye pressure, and bleeding inside the eye. Your surgeon monitors you closely after the operation to detect and address any complications early.
Serious complications like infection and retinal detachment remain uncommon, but prompt treatment becomes critical if they occur.
Success rates and visual outcomes
Studies show patients typically achieve around 50 per cent improvement in vision following surgery. However, individual results vary considerably based on how severe your membrane was before the operation and how long it existed. You might notice significant reduction in distortion even if your vision chart reading improves only modestly. Most patients report improved quality of life after surgery, with better ability to read, drive, and recognise faces. The membrane regrows in fewer than five per cent of cases, requiring repeat surgery.
Surgery costs in Australia
Epiretinal membrane operation costs typically range from $3,000 to $6,000 per eye depending on your surgeon’s fees, hospital charges, and anaesthetist costs. Private health insurance usually covers most of these expenses, though you should confirm your level of coverage before booking surgery. Many practices offer no-gap or known-gap arrangements for insured patients, meaning you pay little to nothing out of pocket. Medicare provides rebates for medically necessary vitrectomy procedures, reducing your overall financial burden.
Next steps
Your epiretinal membrane operation offers the only effective way to restore vision compromised by macular scar tissue. Now that you understand the procedure, recovery timeline, and expected outcomes, you can make an informed decision with your ophthalmologist. Schedule a comprehensive assessment to determine whether surgery suits your specific situation and visual needs. Your surgeon will review your OCT scans, assess the membrane’s impact, and discuss realistic expectations.
