Achieving Ammetropia in Patients with Cataract & Astigmatisme.
Ophthalmol Update Jan ;13(4):304-7.

Objectives: To assess and document the refractive correction of astigmatism in cases of cataract. with astigmatism after Toric IOL implantation. Study Design: Interventional study. Place & Duration: Department of Ophthalmology CMH Rawalpindi. Patients & Methods: Our study included 40 eyes of 23 patients, who had cataract with corneal astigmatism ranging from 1.5 to 6.0 diopters. Visual acuities, IOP, keratometric readings, documentation of steep meridian, pachymetry and corneal topography was done to rule out progressive keratoconus and other corneal ectatic conditions. Phaco-emulsification was done by a clear corneal incision and a Toric IOL was implanted using the Acrysof Toric IOL Calculator. This study group was followed up for 06 months. Results: Post operative astigmatism was assessed after 1st week, 1st month and after 06 months. After the surgery, visual acuities improved significantly in all patients. Astigmatism was definitely reduced in all the patients. The amount of astigmatism which was observed at the end of 06 months was negligible and almost unnoticeable by the patients. Conclusion: Our study shows that Toric IOL Implants help to achieve good vision and reduced dependency on spectacles in about 75% of cases. The Toric IOL implants showed good rotational stability. If IOL rotation occurs within the first week, it can be re-positioned and give the due results in a refractive disorder. Although it is seldom required if placed correctly in the first instance.
