DISTURBANCE OF BLOOD-OCULAR BARRIERS AFTER IMPLANTATION OF POSTERIOR CHAMBER INTRAOCULAR LENS

Abstract

Cataract surgery techniques have improved dramatically ir the past decade. The availability of foldable IOLs and new-generation instrumentation have led to significant refinements in small-incision surgery and improved out-comes.

Although the safety of cataract surgery continues to improve, a physiologic postoperative inflammatory reaction occurs after each small incision cataract surgery. This inflammation is related to such factors as the surgical technique. steroidal and NSAID ad biomaterial of IOL. This postoperative inflammation may cause sight threatening complications as posterior capsule fibrosis, CME or keratopathy.

This study evaluated disturbance in blood-ocular barriers by fluorescein angiography after phacoemulsification and implantation of PMMA or acrylic foldable IOL.

This study was performed on thirty eyes of twenty nine patients of cataract. The studied sample was divided into two groups, the firs: group included I5 eyes which were subjected to planned phacoemulsification with implantation of acrylic foldable IOL in-the-bag. The second group included I5 eyes which were subjected to phac0emulsification with implantation of PMMA IOL in-the-bag.

The age of the studied group ranged from 28 to 70 years with a mean

52.033 + 11.79. the age ranged from 28 to 70 years in the first group and from 38 to 68 in the second group.
