Cataract surgery with toric intraocular lens implantation in keratoconus: a case report.

Abstract:

PURPOSE:We report 2 cases in which cataract extraction with a foldable acrylic toric intraocular lens (IOL) implantation was used to correct (irregular) corneal astigmatism in patients with keratoconus and cataract. METHODS:Case 1 was a 78-year-old man with cataract and keratoconus in the left eye. He underwent phacoemulsification with a toric IOL [Acrysof SN60T9; cylinder power: 6.0 diopters (D)] implantation. Case 2 was a 64-year-old woman with bilateral cataract and keratoconus. She underwent phacoemulsification with toric IOL implantation in the right (Acrysof SN60T9; cylinder power: 6.0 D) and left eyes (Acrysof SN60T5; cylinder power: 3.0 D). Postoperative follow-up in both cases was 6 months. RESULTS:In case 1, the uncorrected visual acuity increased from 20/400 to 20/50. The refractive cylinder decreased from -6.0 to -1.5 D, which is a reduction of 75%. In case 2, the uncorrected visual acuity increased from 20/400 to 20/130 in the right eye and from 20/400 to 20/30 in the left eye. Refractive astigmatism decreased by 70% in both eyes. No IOL misalignment or other complications occurred. CONCLUSIONS:Cataract extraction with toric IOL implantation can be used to correct (irregular) astigmatism and to improve visual functioning in patients with mild to moderate amounts of stable keratoconus and cataract.
