YAG Laser Capsulotomy in Walnut Creek
Cloudy vision returning months or years after cataract surgery? Your cataract has not come back — and the fix takes about three minutes.
YAG laser capsulotomy treats posterior capsule opacification — clouding of the thin membrane that holds your lens implant in place, which can develop months or years after cataract surgery. It is not a returning cataract; a cataract cannot come back. The treatment is a painless in-office laser procedure that takes two to three minutes, requires no incision, needles or stitches, and usually restores clear vision within hours. It is done once per eye and never needs repeating. Medicare and medical insurance cover it.
What has actually happened
During cataract surgery, the clouded natural lens is removed but the clear capsule that held it is deliberately left in place, because it is what holds the new lens implant in the right position. Over time, cells can migrate across the back surface of that capsule and make it hazy. The implant itself stays perfectly clear — you are simply looking through a frosted window in front of it.
This is why the symptoms feel so familiar. Glare, halos around headlights, a gradual dimming, difficulty reading in low light: the same complaints that brought you in for cataract surgery in the first place. Understandably, most patients conclude the cataract has returned. It has not, and the remedy is far simpler than the original operation.
Signs worth mentioning at your next visit
- Vision that was sharp after cataract surgery and has slowly become hazy again
- Increasing glare or starbursts around lights, particularly when driving at night
- Needing more light to read than you did a year ago
- A sense that you are looking through a film or a dirty windscreen
- Reduced contrast — colours and faces looking washed out
These can also be caused by other things, which is why the first step is an examination rather than a booking. Dr. Feiz confirms the capsule is the cause before recommending the laser.
What the procedure involves
- Dilating and numbing drops — about thirty minutes to take effect. No injections.
- A contact lens on the eye — a special lens is rested against the front of the eye to focus the laser precisely. Slightly odd, not painful.
- The laser — two to three minutes. The YAG laser creates a small, precisely sized opening in the centre of the cloudy capsule. You hear faint clicks and see flashes of light. Nothing is cut, and the eye is never opened.
- Pressure check — eye pressure is measured before you leave, since a brief rise is the most common after-effect.
- Steroid drops — you go home with a short course of anti-inflammatory drops to settle the eye. Dr. Feiz will tell you how long to use them.
- Home — someone drives you, because your eye is dilated. Many patients notice clearer vision the same afternoon.
There are no restrictions on activity afterward and no follow-up surgery. Floaters for a few days are normal as fragments of the capsule settle out of the visual axis.
When to have it, and when to wait
The rule is simple: if the vision is good, there is no need to treat. A capsule can look hazy on examination and still not be costing you anything, and in that situation the right answer is to leave it alone and check it again at your next visit. The procedure is worth doing when the haze is actually interfering with what you want to do — reading, driving at night, working — not because it is visible to the examiner.
There is one exception worth knowing about: if there is any chance your lens implant may need to be exchanged or repositioned in future, that is easier to do before the capsule has been opened. Dr. Feiz will raise this if it applies to you.
If you had cataract surgery elsewhere
You do not need to have had your original surgery here. Patients regularly come to Dr. Feiz for YAG capsulotomy after cataract surgery performed by another surgeon, including from practices that have since closed or relocated. Bring whatever records you have, including which lens implant was used if you know it.

Frequently asked questions
Has my cataract come back?
No. A cataract cannot return. The clouded natural lens was removed during your cataract surgery and replaced with an artificial lens implant, and that implant cannot become cloudy. What has happened is that the thin, clear membrane holding the implant in place — the posterior capsule — has become hazy. It is a different structure, and the fix is completely different from cataract surgery.
How common is it?
Very. Posterior capsule opacification develops in a meaningful proportion of patients at some point after cataract surgery, sometimes within months, sometimes after many years. It is considered a normal part of healing rather than a complication, and it happens regardless of how well the original surgery went.
Does the laser hurt?
No. Numbing drops are used, and most patients feel nothing beyond a sense of the lens touching the eye and seeing brief flashes of light. There are no needles, no incision, and no stitches.
How long does it take?
The laser itself takes two to three minutes per eye. Including dilation and a pressure check afterward, budget about an hour and a half at the office.
What is recovery like?
There is essentially none. Vision is often noticeably clearer within hours, sometimes immediately. Dr. Feiz prescribes a short course of anti-inflammatory steroid drops to settle the eye afterward. You may see floaters for a few days as small fragments of capsule settle, which is expected. Most patients return to normal activity the same day, though you will need someone to drive you home because your eye is dilated.
Will I need it done again?
No. The opening created in the capsule is permanent, and the same eye will not need the procedure a second time. If you had cataract surgery in both eyes, each eye may need it at a different time, or one may never need it at all.
What are the risks?
YAG capsulotomy is one of the safest laser procedures in ophthalmology, but it is not risk-free. A brief rise in eye pressure is the most common issue and is checked for before you leave. Uncommonly, patients experience persistent floaters, swelling of the retina, or — rarely — a retinal tear or detachment. Because of that small retinal risk, Dr. Feiz does not recommend the procedure while your vision is still good — if you are seeing well, there is no need to treat.
Is it covered by insurance?
Yes. YAG capsulotomy is medically necessary and is covered by Medicare and medical insurance when the capsule haze is affecting your vision, subject to your deductible and coinsurance. Insurance details →
Can it be done if I have a premium lens implant?
Yes. The procedure works the same way with monofocal, toric, extended-depth-of-focus and full-range lenses. Patients with multifocal implants are sometimes particularly sensitive to capsule haze, because these lenses depend on clear optics to deliver their full range of vision.
