Study Of Visual And Refractive Outcomes In Patients Undergoing Limbal Relaxing Incision During Clear Corneal Phacoemulsification Surgery With Foldable Intra Ocular Lens

Limbal Relaxing Incision During Clear Corneal Phacoemulsification Surgery With Foldable Intra Ocular Lens

Abstract

Background: Phacoemulsification requires a smaller incision, few or no stitches are needed and the patient's recovery time is usually shorter when using a foldable IOL. Limbal Relaxing Incisions, or LRIs, are partial thickness corneal incisions strategically placed to reduce or eliminate pre-existing astigmatism during cataract surgery or refractive lens exchange surgery. Present study was aimed to evaluate the visual and refractive outcome in patients undergoing limbal relaxing incision during clear corneal phacoemulsification surgery with foldable intra ocular lens. Material And Methods: Present study was single-center, prospective, observational study, conducted in patients of age more than 18-75 years, with clear cornea and regular astigmatism on keratometry, with preoperative astigmatism more than or equal to 0.5D on keratometry, fit for phacoemulsification cataract surgery with foldable IOL. Result: A total of 44 eyes of 44 patients who for cataract phacoemulsification surgery, mean age of the patient was 56.98 ± 05.98 years. Refractive acceptance preoperatively was 0.50 D to 2.0 D. On slit lamp examination showed most common Cataract Nucleus grade is NS 3 with PSC preoperatively. We observed improved diopteric difference by automated keratometry on postoperative 90th day as compared to preoperative values. Majority of patients had Preop Keratometric Difference (K1-K2) of 1.5 D, all required LRI Incisions length of 4 clock hours (60°).The difference between the visual acuity preoperatively and post operatively was found to be statistically significant with a p<0.01 by employing the statistical test Analysis of Variance (ANOVA). Visual outcome a change after limb relaxing incisions statistically significant. Keratometry changes preop and postop is statistically significant with p value <0.001. Conclusion: Visual and refractive outcome changes as improved best corrected visual acuity (BCVA), decrease in Corneal Astigmatism was noted in patients undergoing limbal relaxing incision during clear corneal phacoemulsification surgery with foldable intra ocular lens [Sahare H Natl J Integr Res Med, 2021; 12(6): 09-15, Published on 26/01/2022]
