The use of intraocular lenses was a great advance in visual recovery after cataract surgery. Although usually with good biocompatibility, some alterations in the intraocular lens material may occur after implantation. Polymethylmethacrylate was the first intraocular lens material to be used on a large scale and assumed to be inert and well-tolerated. We present a rare case of late opacification...

A 57-year-old male patient visited our clinic for decreased visual acuity in the right eye for 10 days. He denied any trauma history, but recalled that the symptom developed after straining. He had undergone uncomplicated phacoemulsification and posterior chamber intraocular lens (IOL) implantation in the bag of the right eye 11 years ago. The IOL was a three-piece silicone polyimide-haptics de...
متن کاملQuantitative comparison of posterior capsule opacification after polymethylmethacrylate, silicone, and soft acrylic intraocular lens implantation.
OBJECTIVE To quantitatively compare the extent of posterior capsule opacification (PCO) after polymethylmethacrylate (PMMA), silicone, and soft acrylic intraocular lens implantation. PATIENTS AND METHODS A total of 240 eyes from 240 patients undergoing implant surgery were randomized into 3 groups based on the type of lens implanted: PMMA, silicone, and soft acrylic. The density value of PCO ...
