YAG laser capsulotomy is a short clinic procedure that clears a cloudy membrane behind a lens implant after cataract surgery, restoring sharper vision.
Why the capsule becomes cloudy
During cataract surgery the front of the lens capsule is opened, the cloudy lens is removed, and the artificial lens is placed inside the remaining capsule.
Months or years later this capsule can thicken and haze posterior capsule opacification, causing blurred vision and glare similar to a cataract returning.
- Very common and benign change that many people experience over time
- Glasses alone usually cannot overcome the haziness
- Laser creates a clear window in the capsule so light can pass freely
- No incisions are made and recovery is typically rapid
What to expect on the day and afterwards
You sit at a laser machine, often with a special contact lens placed on the eye to help focus the beam, while painless pulses create a neat opening in the capsule.
Vision may be a little blurred and light sensitive for a few hours, but many people notice clearer sight by the next day.
- Pressure lowering drops are sometimes given, and pressure may be checked afterwards
- Floaters can appear temporarily as tiny fragments move in the vitreous
- Serious complications are rare but include raised pressure or retinal problems
- Contact the clinic urgently if you notice worsening pain, redness, or a shadow in vision
