简要总结

To evaluate the visual and refractive outcomes after an intraocular lens (IOL) implantation in pediatric eyes with cataract and preexisting corneal astigmatism

详细描述

This single-center, single-blinded, prospective, randomized controlled trial was performed at two sites of Kazakh Eye Research Institute.

Children with pediatric cataract and corneal astigmatism were included and randomized to two groups for pediatric cataract surgery with toric and non-toric intraocular lens (IOL) implantation. The uncorrected and corrected distance visual acuity, near visual acuity, keratometry data, and residual astigmatism were evaluated.

The purpose of this study is to evaluate the visual and refractive outcomes after a toric IOL implantation in pediatric eyes with cataract and preexisting corneal astigmatism.
