Intraocular lenses: visual results and complications. A comparative study.

The visual results, and the complications, in 100 consecutive Copeland lens implantations combined with intracapsular cataract extraction, are compared with 100 age matched intracapsular cataract extractions without intraocular lens implantations. The visual results are not significantly different (Tables I and II). Patient satisfaction was excellent. The complications, likewise, are not significantly different (Tables III and IV). There were only two dislocations and one implant corneal touch that can definitely be attributed to the presence of an intraocular lens. The dislocations, although a nuisance, left no residual damage. Cystoid macular edema was no more frequent than without implantation. There were no retrolental membranes causing impairment of vision, no late anterior chamber hemorrhages from lens iris chafing or pressure and no lens related glaucoma. Iritis was insignificant and easily controlled with steroids in the few cases observed.
