Long term results of toric intraocular lens implantation for correction of astigmatism in cataract patients with corneal ectasia

Abstract

AbstractPurpose Our purpose was to examine the long‐term efficacy of toric intraocular lens (IOL) implantation in cataract patients with high astigmatism due to corneal ectasia, who underwent phacoemulsification cataract surgery.Methods Seven cases, in which phacoemulsification with toric IOL implantation was used to correct high astigmatism in cataract patients with topographically stable keratoconus or PMD, were reported. Objective and subjective refraction, visual acuity measurement and corneal topography were performed in all cases before and after cataract surgery.Results In all cases, there was a significant improvement in visual acuity, as well as refraction, which remained stable over time. Specifically, in subjective refraction, all patients achieved visual acuity from 7/10 to 9/10 with up to ‐2.50 cyl. Corneal topography also remained stable. Post‐operative follow‐up was 22‐32 months.Conclusion Cataract surgery with toric IOL implantation seems to be safe and effective in correcting astigmatism and improving visual function, in cataract patients with topographically stable keratoconus or PMD.
