Clinical Results of 500 Cases of Intraocular Lens Implantation(I)

ABSTRACT

From May, 1985 to July, 1986, 500 cases of intraocular lenses were implanted, and all 500 cases had been followed up for more than 2 months. The results were as follows 1. In the 500 cases of intraocular lens implantation, the number of patients were 318 men and 115 women. Patient's age was largely distributed to fifth decade in men and fourth decade in women. 2. IOL power ranged from +13.5D to +23.0D in PCL and ranged from +12.5D to +20.0D in ACL. The most frequently used IOL poeer was +19.5D in PCL and +18.0D in ACL. 3. Postoperative corrective vision with IOL was improved up to 0.8 or better in 446 cases(89.2%). 4. During operation, some complications were developed and those were posterior capsular rupture in 19 cases(3.8%), hyphema in 15 cases(3.0%), Descemet's membrane stripping in 2 cases(0.4%), and corneal edema in 1 case(0.2%). More frequently developed postoperative complications were clinical cystoid macular edema in 26 cases(5.2%), secondary glaucoma in 18 cases(3.6%), and distorted pupil in 13 cases(2.6%). 5. Postoperative corrective vision lower than 0.4 was observed in 22 cases(4.4 %), and the causes were diabetic retinopathy, cystoid macular edema, vitreous opacity, congenital cataract, phacoanaphylactic uveitis, endophthalmitis, amblyopia, optic nerve atrophy, corneal opacity, glaucoma, hypertensive retinopathy, and others.
