Visual outcome with superior, superotemporal and temporal incisions used in phacoemulsification surgery - a comparative study
Journal Title: MedPulse -International Medical Journal - Year 2014, Vol 1, Issue 8
Abstract
Introduction: Quality of vision and early rehabilitation are two critical parameters that determine the success of modern cataract surgery. To achieve this, length and location of incision are the most important factors which play crucial role in reducing surgically induced astigmatism and rehabilitation time after surgery. Aims and Objectives: To compare Visual outcome with superior, superotemporal and temporal incisions used in phacoemulsification surgery Materials and Method: This prospective study comprised of 150 patients of cataract operated by using phacoemulsification using superior, superotemporal and temporal incisions. All the patients were divided in three groups containing 50 patients each depending upon the type of incision used. The outcome measures were uncorrected and best corrected visual outcome post operatively. Results: Majority of the cases were having visual acuity (VA) in the range 4/60 - 6/60 preoperatively. The mean uncorrected visual acuity on 40th post-operative day in Group A, B and C was 0.4862±0.2199, 0.5522±0.2386 and 0.5810±0.2102 in decimals. There was no statistically significant difference in the post-operative uncorrected visual acuity at day 40 between Group A, B and C (95% confidence interval) using one way ANOVA test. The BCVA on 40th post-operative day was 6/6 and 6/9 in 30 (60%) in Group A, 33 (66%) cases in Group B and 37 (74%) cases in Group C. There was no statistically significant difference in best corrected visual acuity between Group A, B and C (p=0.6628, p>0.05) using one way ANOVA test. Conclusion: The uncorrected visual acuity was slightly better in the temporal incision group as compared to the superior incision group. Thus the efficacy of superior, superotemporal and temporal incisions in view of post-operative visual rehabilitation is similar.
