Comparison of VERION Image-guided System withManual Marking in Limbal Relaxing Incision toReduce Astigmatism in Eyes with Cataract

Introduction: To compare the results of Verion system with manual marking in the reduction of astigmatism in eyes with cataract and low to moderate astigmatism by forming limbal relaxing incisions (LRIs).Methods: Thirty-eight eyes of 22 patients who had undergone standard phacoemulsification surgery and limbal relaxing incision for astigmatic correction with the help of image-guided system (Verion) were compared retrospectively with 40 eyes of 24 patients, who had undergone standard phacoemulsification surgery and limbal relaxing incision for astigmatic correction with manual marking.Results: There was no significant difference between two groups concerning the mean 1st and 6th month postoperative un-corrected visual acuity (UCVA), best-corrected visual acuity (BCVA), spherical and cylindrical values (p-values, 0.054, 0.068, 0.946, 0.957, 0.971, 0.947, 0.254 and 0.195, respectively). Even though the mean postoperative 1st-month and 6th-month cylindrical values of the second group were higher than those of the first group, the difference was not significant statistically.Discussion and Conclusion: LRIs performed during cataract surgery are efficient in reduction of low to moderate astigma-tism. LRIs performed with Verion system seem to be not different significantly from LRIs performed with manual marking in the reduction of astigmatism during cataract surgery.
