Patients enlisted for phacoemulsification cataract surgery with coexisting<br>astigmatism were recruited and divided into two groups. Eyes that<br>underwent cataract surgery with limbal relaxing incisions (cataract LRI group)<br>and eyes that underwent cataract surgery only (control group). All patients<br>underwent a comprehensive baseline ophthalmic examination that included<br>uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA),<br>manifest refraction, anterior segment slit – lamp examination, 90 D examination<br>of fundus, keratometry and ultrasound biometry. Patients were evaluated at 1st<br>day, 1st month and 3rd month postoperatively Post-operative examination<br>included BCVA, anterior segment slit-lamp microscopy and keratometry. The<br>data thus obtained was analyzed on SPSS 17.<br>Results: A total of 50 eyes (29 right eyes and 21 left eyes) of 44 patients were<br>included in the study. Mean patients age was 61 yrs ± 11.3 yrs (range: 30 to 80)<br>in the LRI group and 57 yrs ± 11.8 yrs (range 30 to 80) in the control group. Data<br>analysis demonstrated statistically significant reduction in the mean postoperative<br>astigmatism in the LRI eyes from 1.78 ± 0.81 D@125° (range: 0.75 to<br>3.70 D) preoperatively to 0.73 ± 0.71 D @ 130° (range: 0.0 to 2.70) in the 3rd<br>postoperative month as compared to control group from 1.28 ± 0.41 D @ 145°<br>(range: 0.75 to 1.97 D) preoperatively to 1.17 ± 0.57 D @ 144° (range: 0.10 to<br>2.30) p-value 0.021. There were no intraoperative complications or postoperative<br>subjective complaints (such as halo or glare) in our patients.<br>Conclusion: Limbal relaxing incisions performed during phacoemulsification<br>surgery appear to be safe and effective procedure to reduce pre-existing corneal<br>astigmatism.<br>Key Words: Limbal relaxing incision, Phacoemulsification, Astigmatism.</p> ER -
