Intraocular lens pittings

This 75 year-old diabetic woman underwent right phacoemulsification and implant 2 years ago. Post-operatively, her vision declined to counting fingers due to opacity of the posterior lens surface. Her ophthalmologist attempted YAG laser but failed to create significant lens clearing. Instead, some lens pittings were created.

Two options are available to improve her vision. Posterior lens polishing and if this fails, lens exchange.

Pittings of the lens from YAG laser. Some but insufficient clearing

of the central posterior lenticular opacity.
