Cause After surgery, capsule cells can grow and cloud over, causing vision to become blurry or hazy again.
Solution The YAG laser creates a precise opening in the cloudy capsule, allowing light to pass freely to the retina.
Result Vision improvement occurs the same day. The capsule cannot cloud again — the procedure is performed only once.
During cataract surgery, the surgeon preserves the posterior capsule — a thin transparent membrane — to serve as a platform for the artificial lens. Over time, cells on its surface can proliferate and cause clouding.
PCO occurs in 20–40% of patients within 2–5 years after cataract surgery. This is entirely normal — not a complication, and not a return of the cataract.
If you recognize these symptoms, tell Dr. Benjamin. YAG capsulotomy quickly and completely restores vision.
Preparation Dilating and numbing drops are applied. No special preparation — you may eat and drink normally.
Procedure You sit at the slit lamp. A special contact lens-mirror is placed on the eye. The YAG laser creates an opening in the capsule in 2–5 minutes.
Sensations You will hear gentle clicks and see flashes of light. There is no pain. Most patients describe it as completely painless.
After Vision improves within a few hours. Temporary floaters or spots may appear — resolve within a few days.
Follow-Up In 1–2 weeks — a visit to measure IOP and assess the result.
▸ Anti-inflammatory drops — 3–5 days
▸ If IOP rises — additional drops as prescribed
▸ Your regular drops — continue on the usual schedule
Follow Dr. Benjamin's exact instructions regarding drops after the procedure
Vision may be temporarily blurry from dilating drops. Do not drive — bring a companion. Normal activities are permitted.
Sudden vision loss, increasing pain, redness, or a significant increase in floaters or flashes — symptoms that require immediate evaluation.
