Abstract Details


We report nine keratoconus also cataract patients in which phacoemulcification cataract surgery with foldable acrylic toric intraocular lens implantation was used to offer these patients an optimal result.The purpose of this report is to present results of minimum six months follow up in a case of stable keratoconus and cataract patients which treated with toric intraocular lens implantation.


Cagin Eye Hospital


In this study 9 eyes of 9 patients with keratoconus who underwent cataract surgery using the toric intraocular lens implantation.All patients have stable keratoconus and they are over fifty years old.Follow up time is 6 month. For calculating of the IOL's power Iolmaster (Zeiss),and Alcon toric calculator were used. In all cases SRK T formula was used.We use the Pentacam (Oculus) corneal topographer which provides true net power maps and EKR(equivalent K -readings). During the surgery Verion Digital Marker was used.In the all cases SN6AT model (Alcon) aspheric acrylic IOL's were used.All surgeries were done by two surgeons.


The mean uncorrected visual acuity increased significantly one week after surgery.The mean uncorrected visual acuity was 20/40 or better in %72, corrected visual acuity was 20/40 or better in %86 of eyes.Post operative mean refractive sphere was �.0--1.0 D in %75 and cylinder �.0 with -1.0 D in %65 of eyes.There was not any significant IOL rotation at the post operative period.Intraoperative and postoperative complications were not occured.


Toric IOL implantation in keratoconus patients is an effective option and provide good vision in eyes with stable mild to moderate keratoconus and cataract patients. However modern topographies and formulas significantly contribute to enhance the predictability of the manifest refraction after uneventful cataract surgery
