Aim:The aim of this study is to examine the cylinder power change by comparing the use of eye markings made manually with those aided by an image-guided system (Verion) after LRI (limbal relaxation incision) in cataract surgery for astigmatism correction. Method:Setting: Surgical Suite, Hawaii, USA Design: Retrospective comparative study. Thirty eyes from 30 consecutive patients with cataracts and low corneal astigmatism had LRI during phacoemulsification were included. Fifteen eyes had placement of LRI with eye markings manually and fifteen eyes had LRI with eye markings guided by Verion Image System. The changes in cylinder power were found and the mean of these changes were calculated for comparison. Results:The mean absolute change in cylinder between the groups was 0.78 in the manual group and 0.98 in the Verion group (p=0.63). The mean relative percent change in cylinder was 49.1% and 55.8% in the manual and Verion groups respectively. Conclusion:LRIs made with eye imaging guided system such as Verion compared favorably with manual marking in correcting cylinder in cataract surgery.
