초록
목적: 회절-굴절형 후면을 가진 다초점 인공수정체인 OptiVisTM의 임상성적을 알아보고, 회절형 다초점 인공수정체인 AcrySofⓇReSTORⓇ D1과 차이를 알아보았다. 대상과 방법: 백내장 수술 후 OptiVisTM를 삽입한 환자 11명 20안과 AcrySofⓇ ReSTORⓇ D1를 삽입한 환자 10명 20안을 대상으로 술전과 술 후 1주, 1개월, 2개월에 나안 및 교정 근거리, 중간거리, 원거리 시력을 측정하고 중심이탈, 경사도, 대비감도와 고위수차의변화를 분석하였다. 또한 술 후 2개월에 defocus curve를 확인하고, 전반적 환자 만족도를 조사하였다. 결과: OptiVisTM 삽입 후 2개월째 평균 나안시력은 근거리 0.09 ± 0.10, 중간거리 0.11 ± 0.08, 원거리 0.08 ± 0.07이였고, 두 군간의원거리, 근거리 시력은 통계적으로 유의한 차이는 보이지 않았으나 중간거리 시력은 OptiVisTM 군에서 통계적으로 유의하게 높게 나타났다. 중심이탈, 경사도, 대비감도와 고위수차는 두군에서 유의한 차이는 없었다. 결론: OptiVisTM 인공수정체는 원거리 및 근거리 시력 저하 없이 우수한 중간거리 시력교정이 가능하여 높은 만족도를 보였다.
Abstract
Purpose: To evaluate the efficacy of the OptiVisTM Multifocal intraocular lens (IOL) and compare the clinical outcome between OptiVisTM and AcrySofⓇ ReSTORⓇ D1. Methods: We reviewed 20 eyes of 11 patients implanted with OptiVisTM and 20 eyes of 10 patients implanted with AcrySofⓇReSTORⓇ D1. The clinical outcomes of the 2 IOLs were evaluated 1 and 2 months postoperatively and consisted of distant,intermediate, and near visual acuity, depth of focus, contrast sensitivity, wavefront aberration, patient satisfaction, decentration and IOL tilt. Results: Intermediate vision was better in the OptiVisTM group. There were no statistical differences between the 2 groups with respect to distant vision, near vision and wavefront aberration, contrast sensitivity, decentration and IOL tilt. Depth of focus was deeper in the OptiVisTM group at the intermediate visual acuity zone. There were no statistically significant result differences between postoperative 1 and 2 months. Conclusions: The OptiVisTM multifocal IOL provided satisfactory visual acuity at distance, near, and intermediate with no apparent reduction in contrast sensitivity. The IOL can be effective for improving patient satisfaction after cataract surgery as well as correcting presbyopia.
