Abstract

In our study of total 25 patients undergoing cataract surgery (Phacoemulsification with Foldable IOL) with high myopia with IOL power ranging from -7D to 13D and Axial length ranging from 25.72mm to 35.02mm, IOL power calculation was done by using Barrett’s Universal II formula. Patients with high myopia are known to have a refractive surprise post cataract surgery due to large ACD (anterior chamber depth), resulting to variation on ELP (Effective lens position), causing postoperative Hyperopic refractive shift. The outcomes in our study were achieved with target myopia (residual refraction) of -0.5Dto -2.0D. Monovision in patients who were suitable was planned after dominance test to ensure spectacle independence. In our study 84% patients had SE (spherical equivalent) between -0.5D to -1.0D and 14% were between -1.0D to -2.0D. Hence optimizing IOL power is an important factor to improve patient’s satisfaction in high myopia cases.
