Yes, a macular hole can be repaired, and surgery is successful in closing the hole about 85% of the time on the first attempt. For larger or more stubborn holes, advanced techniques push that closure rate to 95% or higher. Most people see meaningful vision improvement afterward, with average vision improving from roughly 20/100 before surgery to 20/34 a year later.
Whether you need surgery, and how urgently, depends on how far the hole has progressed. Here’s what you should know about the condition, the repair process, and what recovery actually looks like.
How Macular Holes Progress
A macular hole is a small break in the macula, the central part of your retina responsible for sharp, detailed vision. It typically develops when the gel-like substance inside your eye (the vitreous) shrinks with age and tugs on the macula until the tissue tears. The condition progresses through four stages, and the stage determines whether you need treatment right away or can wait.
In stage 1, the fovea (the very center of the macula) starts to lift but hasn’t fully torn. About half of stage 1 holes resolve on their own, so your eye doctor will typically monitor you rather than recommend surgery. If your vision drops significantly and symptoms persist, surgery may be considered even at this early point.
Stage 2 is a full-thickness hole smaller than 400 micrometers. Nearly all stage 2 holes progress to stage 3 without treatment, so surgery is generally recommended here. Stage 3 holes are larger than 400 micrometers and involve partial separation of the vitreous from the retina. Stage 4 holes have complete vitreous separation. Only about 4% to 11% of full-thickness holes close spontaneously, which is why surgery becomes the standard path for stages 2 through 4.
How the Surgery Works
The operation used to repair a macular hole is called a vitrectomy. It’s performed under local anesthesia in most cases, meaning you’re awake but your eye is completely numbed. The surgeon makes tiny incisions in the white of the eye and uses miniature instruments to remove the vitreous gel that’s pulling on your macula.
If the vitreous is still attached to the back of the eye, the surgeon carefully separates it. Then comes a critical step: peeling a thin membrane called the internal limiting membrane (ILM) from the surface of the retina around the hole. Removing this membrane releases tension on the macula and allows the hole to close. Finally, the surgeon fills the eye with a gas bubble. This bubble presses gently against the macula, holding the edges of the hole together while it heals. Your body gradually reabsorbs the gas and replaces it with natural fluid over the following weeks.
The Inverted Flap Technique for Large Holes
For holes larger than 400 micrometers, or holes that failed to close after a first surgery, surgeons can use a variation called the inverted ILM flap technique. Instead of completely removing the membrane, the surgeon peels it partway and folds it over the hole like a flap. This flap acts as a scaffold that encourages retinal cells to grow across the gap and fill in the hole. A meta-analysis of eight studies found this technique achieved a 95% closure rate for large holes, compared to 88% with standard peeling. For extremely large holes (over 1,000 micrometers), every eye treated with the flap technique achieved complete closure.
A Non-Surgical Option for Small Holes
For certain small macular holes where the vitreous is still tugging on the macula, there’s a non-surgical alternative: an injection of an enzyme that dissolves the attachment between the vitreous and the retina. In clinical trials published in the New England Journal of Medicine, this injection closed macular holes in about 41% of treated eyes, compared to roughly 11% in eyes that received a placebo. It also reduced the number of patients who eventually needed surgery. The injection works best for small holes with clear vitreous traction and won’t be appropriate for larger or more advanced holes, but it offers a less invasive first step for the right candidates.
What Recovery Looks Like
Recovery from macular hole surgery is unlike most operations because of one key requirement: positioning. After surgery, you’ll need to keep your head in a face-down position so the gas bubble floats up against the macula at the back of your eye. Some surgeons ask for strict face-down positioning for 50 minutes of every hour, including overnight, for one to two weeks. Others use shorter protocols. The exact duration your surgeon recommends will depend on the size of your hole and the type of gas used.
The gas bubble itself takes time to disappear. A lighter gas (SF6) lasts about 18 days on average. A heavier, longer-acting gas (C3F8) lasts roughly 68 days. During this time, your vision in that eye will be very blurry because you’re essentially looking through a bubble. As the gas reabsorbs, your vision gradually clears from the top of your visual field downward.
One firm restriction: you cannot fly or travel to high altitudes while the gas bubble is in your eye. Changes in air pressure cause the bubble to expand, which can dangerously raise the pressure inside your eye. This restriction lasts until the gas is fully absorbed, so plan accordingly if you have travel commitments.
How Much Vision You Can Expect to Regain
Vision improvement is gradual. In a study tracking patients for a full year, 80% gained at least three lines on the eye chart, which is a noticeable, meaningful change. The average patient went from seeing 20/100 (legally impaired) to 20/34 (close to normal driving vision). No patients in that study had worse vision after surgery than before. Full visual rehabilitation can take up to a year, with quality-of-life scores continuing to improve between three months and twelve months after the procedure.
That said, most people don’t regain perfect 20/20 vision. The amount of improvement depends on how long the hole was present before repair, how large it was, and individual healing factors. Smaller holes caught earlier tend to produce better visual outcomes.
Risks and Side Effects
The most common long-term consequence of vitrectomy is cataract development. In one study, 79% of eyes that still had their natural lens eventually needed cataract surgery within the follow-up period. This is so predictable that some surgeons discuss combining macular hole repair with cataract surgery, particularly in older patients who already have early lens clouding.
Other risks include infection, bleeding, and retinal detachment, though these are uncommon. There’s also a small chance the hole won’t close on the first attempt. If that happens, a second surgery, often using the inverted flap technique, has a high success rate.
Can the Hole Reopen?
Reopening is uncommon but possible. In a large case series of 353 successfully repaired holes, 17 reopened, a rate of about 4.8%. When this happens, repeat surgery is typically effective. Your surgeon will schedule follow-up visits using optical coherence tomography (OCT) scans to confirm the hole has closed and stays closed.
