The Analysis of Refraction and Accommodation of Extreme Myopia with Cataract after Phacoemulsification and IOL Implantation

Abstract

Abstract:Background: To assess the refractive status of cataract patients with extreme myopia and to measure their accommodative capability after monofocal IOL implantation. Design: Prospective non-randomized study conducted at Tianjin Medical University Eye Centre.Participants: 18 patients with 34 extreme myopic eyes ≥27mm axial length), and 14 patients with 27 non-myopic eyes that had uneventful phacoemulsification and monofocal IOL implantation. Methods:The accommodation amplitude of the two groups was compared pre-and post-operatively using subjective minus-lenses-to-blur method. In the extreme myopic group, the postoperative target refraction was selected to be myopic, and they were evaluated for predicted postoperative spherical power consistency.
