A clinical study to evaluate the results after toric intraocular lens implantation in cases of corneal astigmatism

Journal Title: Medical Journal Armed Forces - Year 2018, Vol 74, Issue 2

Abstract

Backgroud: Modern day cataract surgery aims at a spectacle free vision which becomes difficult in cases with pre-operative astigmatism more than 1.5 D. Implantation of toric intra-ocular lenses (IOL) after phacoemulsification in such eyes is one of the ways to counteract this problem. Methods: Thirty eyes with pre-operative astigmatism between 1.5 D and 4.5 D were implanted with toric IOLs following uneventful phaco-emulsification. The estimation of the axis of implantation of this toric IOL included calculating the surgically induced astigmatism (SIA) of the surgeon. Results: Post-operatively, 20 (66.67%) patients had a visual acuity 6/9 or better and 17 (57%) had a visual acuity of 6/6 at 12 weeks. The mean postoperative uncorrected visual acuity (UCVA) was 0.12  0.15 at 12 weeks. The difference between means of preoperative best corrected visual acuity (BCVA) LogMAR and postoperative UCVA at 12 wk LogMAR was found to be statistically significant at p = 0.001. Mean (SD) scores of pre-op astigmatism of study group was 2.20 (0.67) and residual astigmatism was 0.32 (0.44). Conclusions: The difference between means of pre-op astigmatism and residual astigmatism in the study group was significant at p = 0.001 with 95% CI 2.22 to 1.50. This significant difference was because of the toric IOL implantation.
