A Clinical Study on Cataract Surgery in High Myopia: Pseudophakia and Aphakia

ABSTRACT

Anthors have evaluated postoperative visual outcome and complications on 60 high myopic patients who had underwent extracapsular cataract extraction (ECCE) with or without posterior chamber intraocular lens (PC IOL) implantation, retrospectively. The average axial length of eyeballs of patients underwent only ECCE and ECCE with PC IOL were 30.7 mm and 27.04 mm, respectively. Corrected visual acuity was improved in 56 eyes (91.5%) after cataract sugery. 19 eyes (63.6%) out of 30 aphakia and 11 eyes(36.2%) out of 30 pseudophakia showed better than 20/40 and this difference was statistically significant (p< 0.05). Posterior capsular opacity and cystoid macular edema (CME) were founf in 7 eyes (23.3%) and in 2 eyes (6.6%) of 30 aphakia, while those were in 2 eyes (6.6%) and 1 eye (3.3.%) of 30 pseudophakia, respectively. However, these complications did not decrease a visual acuity and there was no retinal detachment in both aphakia and pseudophakia, with these resuls, it was founf that the clinical results of ECCE with PC IOL was more effective in visual improvement and prevention of posterior capsular opacity than only ECCE for high myopic patients.
