ANALYSIS OF VISUAL OUTCOME IN CATARACT PATIENTS WITH CORNEAL ASTIGMATISM UNDERGOING CATARACT SURGERY TORIC IOL IMPLANTATION
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 49
Abstract
BACKGROUND Correction of pre-existing corneal astigmatism is a challenge in managing cataract patients as the residual pre-existing astigmatism in the post-operative period compromises the uncorrected visual activity. The toric intraocular lens (IOL) neutralizes the pre-existing anterior corneal astigmatism, with predictable visual outcome of close to hundred percent if there is no associated fundus pathology. MATERIALS AND METHODS This is a cross sectional study and a retrospective analysis of 468 eyes of 434 patients with pre-operative astigmatism of 1.5 D to 6.5 D cylinder. All patients underwent phacoemulsification with acrylic toric IOL implantation (AcrySof Toric IOL). The patients were assessed on 6th day and one-month post-op. The visual outcome was measured using Snellen Visual Acuity Chart (UCVA), refraction done and rotation of the IOL noted if existed. RESULTS Mean UCVA improved to 6/6 nil glasses for distance in 468 number of patients. The mean refractive active medicine reduced from the pre-operative value of 0.6 D to 0.20±0.60 D. CONCLUSION AcrySof toric IOL is an effective tool to correct pre-operative astigmatism in cataract patients expecting spectacle independence for distance.
