The Effect of Capsulorhexis Size On Changes In The Anterior Chamber Depth And Iridocorneal Angle In Post Phacoemulsification Patient With Intraocular Lens Implantation

Abstract

Introduction: In several studies stated that cataract surgery is the most common surgical procedure performed in daily medical practice throughout the world. The success of cataract surgery is greatly influenced by several factors including continuous curvilinear capsulorhexis. From the existing literature to date, not much has been studied about the effect of capsular hexis size on components of the anterior segment of the eyeball such as BMD and iridocorneal angle in patients who have undergone phacoemulsification surgery, for this reason researchers are interested in researching it. Methodology: This study was conducted on 88 patients with aged related cataracts who underwent phacoemulsification surgery with intraocular lens implantation using consecutive sampling. Divided into two groups with small and large capsulorhexis sizes. Changes in anterior chamber depth and iridocorneal angle before and after surgery were compared between groups. Results: In the comparison of the two groups there was a significant difference in the average anterior chamber depth between before and after surgery with p <0.001, but the results of comparison of anterior chamber depth between groups did not obtain significant results with p = 0.573 (p > 0, 05). For the iridiocorneal angle, there were also significant differences on the nasal and temporal sides before and after with p <0.05, but the comparison between groups of small rhexis diameter and large changes in the iridocorneal angle was not significant with p>0.05. Conclusion: Phacoemulsification surgery with a large rhexis diameter resulted in a shallower chamber depth and narrower iridocorneal angle when compared to patients with a smaller rhexis diameter although it was not statistically significant
