stomized toric intraocular lens implantation for correction of extreme corneal astigmatism due to corneal scarring Case report (3583) Total Article Views Authors: R Bassily, J Luck Published Date March 2010 Volume 2010:2 Pages 21 - 24 DOI: http://dx.doi.org/10.2147/OPTO.S9305 R Bassily, J Luck Ophthalmology Department, Royal United Hospital, Combe Park, Bath, UK Abstract: A 76-year-old woman presented with decreased visual function due to cataract formation. Twenty-five years prior she developed right sided corneal ulceration that left her with 10.8 diopters (D) of irregular astigmatism at 71.8° (steep axis). Her uncorrected visual acuity was 6/24 and could only ever wear a balanced lens due to the high cylindrical error. Cataract surgery was planned with a custom designed toric intraocular lens (IOL) with +16.0 D sphere inserted via a wound at the steep axis of corneal astigmatism. Postoperative refraction was -0.75/+1.50 × 177° with a visual acuity of 6/9 that has remained unchanged at six-week follow-up with no IOL rotation. This case demonstrates the value of high power toric IOLs for the correction of pathological corneal astigmatism.
