SUMMARY Intraocular lens (IOL) implantation is now accepted as the most effective means of aphakic correction in selected patients undergoing cataract surgery. In terms of final rehabilitation, however, complications such as comeal oedema, retinal detachment, and cystoid macular oedema remain problematic. Results of prospective concurrent trials of IOL implantation performed at the Wilmer Institute are presented, with particular reference to the posterior chamber intraocular lens and with specific emphasis on postoperative complications.As the second leading cause ofblindness in the United States cataract constitutes an important public health problem.
IIncreasingly sophisticated modes of operative instrumentation, along with earlier and more effective visual rehabilitation, have served to stimulate an increase in the rate of cataract surgery: of 640000 cataract operations performed in the United States in 1982 over 70% were associated with intraocular lens implantation.2 In the most recent 6-month interval of the FDA study the posterior chamber lens accounted for 48% of all intraocular lenses implanted and the anterior chamber lens, 45%.4 The purpose of this report is to present our personal experience with posterior chamber intraocular lens implantation, particularly with reference to postoperative complications such as corneal oedema, retinal detachment, and cystoid macular oedema. Results have been evaluated in the context of the broader Wilmer intraocular lens experience, comparing current methods with previously utilised techniques.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
