Post-operatively, the patients were reviewed at day 1, week 1, week 6 for the same parameters.Statistics:Quantitative variables: Paired and unpaired t-test.Qualitative variables: Chi square test.A P-value of < 0.05 was considered statistically significant.Results: Inter-group comparisons of post-operative change in ACD at 1-week post-op (P-value< 0.001) and 6-week post-op (P-value< 0.001) were statistically significant when compared to the pre-op values. The mean spherical equivalent in group I was 0.27± 0.26 d and that in group II was 1± 0.32 d at 1-week post-op. The mean spherical equivalent in group I was 0.23± 0.20 d, while that in group II was 0.85± 0.64 d at 6-week post-op. This difference was statistically significant both at 1-week post-op (P-value=0.002) and 6-week post-op (P-value< 0.001).Conclusion: Post-phacoemulsification, the ACD is more after peribulbar anesthesia as compared to topical anesthesia. Post-op refractive outcome is better with the use of topical anesthesia.Keywords: phacoemulsification, topical anesthesia, peribulbar anesthesia, ACD, MSE |
