목적: 수정체 전낭절개 확장이 백내장 수술 후 인공수정체의 회전에 미치는 영향을 인공수정체의 종류에 따라 비교해보고 영향을 주는 인자들에 대해 분석해보고자 한다. 대상과 방법: 2009년 3월부터 2010년 12월까지 SN60WF, ZA9003, MI60, XL Stabi ZO의 네 가지 인공수정체를 삽입한 128명 151안을 대상으로 전향적으로 연구하였다. 전낭수축 방지를 위해 수정체낭원형절개를 일부 확장시키거나 수술 중 전낭이 의도하지 않게 일부 확장된 64안을 대상으로 하였다. 수술 당일과 1주일 후 산동후 전안부 촬영으로 인공수정체 회전을 평가하였다. 결과: 인공수정체의 회전은 네 가지 인공수정체간에 유의한 차이를 보이지 않았다. 수정체낭원형절개 확장한 군과 수정체낭원형절개 확장하지 않은 군 간에도 유의한 차이를 보이진 않았다. 나이와 인공수정체 회전 간에 양의 상관관계가 있었으며, 안축장, 전방깊이와 부피 등은 인공수정체 회전에 영향을 주지 않았다. 결론: 수정체 전낭절개의 일부 확장이 백내장 수술 후 인공수정체 회전에 영향을 주지 않았으며, 네 가지 재질과 디자인을 가진 인공수정체 모두 난시교정렌즈에 적용될 수 있을 것으로 생각한다.
Abstract
Purpose: To evaluate the effects of anterior capsulotomy extension on the rotational stability of four different types of intraocular lenses (IOLs) and to analyze factors influencing IOL rotation. Methods: The present single-center prospective study was comprised of 128 cataract patients (151 eyes) who underwent cataract surgery and received AcrySof IQ SN60WF, Tecnis ZA9003, Akreos MI60, or Zeiss XL Stabi ZO from March 2010 to December 2010. Sixty-four eyes received an anterior capsulotomy extension which was unintentionally created or performed using Vannas scissors after capsulorrhexis to prevent anterior capsular contracture. After pupil dilation, a digital retroillumination image of the IOL was taken on the operative day and 7 days postoperatively. Results: There was no statistically significant difference in IOL rotation between the 4 types of IOL (p > 0.05). The anterior capsulotomy extension group (2.72±2.42°) and the non-extension group (3.24±2.16°) did not show statistically significant differences in IOL rotation (p > 0.05). A positive correlation was observed between age and IOL rotation. Axial length, anterior chamber depth, and anterior chamber volume did not affect the degree of rotation. Conclusions: Among the 4 types of IOLs, there was no significant difference in rotational stability. Anterior capsulotomy extension to prevent anterior capsular contracture is not likely to significantly affect the rotational stability of IOLs; the 4 different types of IOL were stable in the eye and suitable as toric IOLs for correction of astigmatism.
