Comparison of Clinical Results between 0 Diopter Pseudophakia and Aphakia in High Myopia

ABSTRACT

We have evaluated the outcome of the high myopic patients who had been underwent cataract extraction with 0 diopter posterior chamber intraocular lens (PC IOL)implantation (15 eyes)and without PC IOL implantation (11 eyes), retrospectively.The average axial length was 31.1 mm and the average calculated diopter of PC IOL was +0.48 diopter.The preoperative corrected visual acuity (VA)had no statistically difference between the two groups.But the numbers of eyes that had postoperative corrected VA above 20/40 were 1 of 11 aphakic eyes and 7 of 15 pseudophakic eyes, and had significant difference (p<0.05).The after cataracts were found in 4 eyes of aphakic eyes and 1 eye of 0 diopter pseudophakic eyes.Among of them, 4 eyes of aphakic eyes underwent NdYAG laser posterior capsulotomy and not revealed the retinal detachment.So we thought that PC IOL implantation after cataract extraction in high myopic eyes could improve the visualacuity, decrease the incidence of after cataract and retinal detachment.
