초록
목적: 새롭게 개발된 친수성과 소수성의 특징을 모두 지닌 일체형 비구면 인공수정체 enVista MX60의 술 후 3개월째 임상 결과를기존에 널리 사용되는 일체형 비구면 인공수정체인 AcrySof SN60WF와 TECNIS ZCB00과 비교하였다. 대상과 방법: 동일한 술자에게 수정체유화술 후 위의 세 가지 일체형 비구면 인공수정체 중 하나를 삽입한 62안을 대상으로 수술 3개월후 나안시력, 최대교정시력, 구면렌즈 대응치, 고위수차, 변조전달기능을 측정하여 비교하였다. 결과: 세 가지 인공수정체의 술 후 3개월째 나안시력, 최대교정시력 및 수술 전 목표치와 수술 후 구면렌즈 대응치 간의 차이를 비교한결과, 모두 유의한 차이를 보이지 않았다. 고위 수차의 경우 안구 내 전체 수차, 각막수차 및 안구 내 수차에서 세 군 모두 고위 수차의총합 및 세부 수차의 차이를 보이지 않았다. 결론: 친수성과 소수성의 특징을 모두 지닌 새로운 일체형 비구면 인공수정체인 enVista MX60은 기존에 임상효과가 검증되었던AcrySof SN60WF와 TECNIS ZCB00와 대등한 임상 결과를 보였다.
Abstract
Purpose: To compare the clinical 3 months postoperative results of three different 1-piece aspheric intraocular lenses (IOLs): AcrySof IQ SN60WF (Alcon Laboratories, INC, Fort Worth, TX), TECNIS 1-piece ZCB00 (AMO Inc., Santa Ana,CA) and the newly developed enVista MX60 (Bausch & Lomb, Rochester, NY). Methods: In a total of 62 eyes, 1 of the 3 1-piece aspheric IOLs, AcrySof IQ SN60WF, TECNIS 1-piece ZCB00 or enVista MX60 was implanted after cataract extraction. Best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), and spherical equivalent were assessed 3 months postoperatively. Total spherical aberration, high order aberration, and modulation transfer function were analyzed. Results: There were no significant differences of UCVA, BCVA, the accuracy of postoperative refractive power, and modulation transfer function among the 3 IOLs. Higher order aberrations of the entire eye and internal optics showed almost no significant differences. Conclusions: The newly developed IOL, enVista MX60, showed equivalent clinical outcomes as both AcrySof IQ SN60WF and TECNIS 1-piece ZCB00.
