초록
목적: 다초점 비구면 인공수정체인 Acri.Lisa 366D를 삽입한 환자들의 시각 및 광학적 단기 임상 결과를 알아보고자 하였다. 대상과 방법: Acri.Lisa 366D를 양안에 삽입한 20명 40안을 대상으로 수술 1주, 1개월, 3개월에 근거리 및 원거리 시력, 굴절 오차, 대비감도, 웨이브프론트 수차를 측정하였고, 시기능 설문조사를 시행하여 환자 만족도에 대해 조사하였다. 결과: 술 후 1개월째 나안시력은 근거리 0.09±0.14, 중간거리 0.29±0.17, 원거리 0.11±0.12였고 6개월째에 큰 변화는 없었다. 웨이브프론트 수차는 전체수차 0.66±0.29였고 고위수차는 0.24±0.08이었다. 시기능 설문조사 결과는 총점 3,127점±354였고 근거리 시력 244점±36, 원거리 시력 256±21, 운전기능 221±42였다. 결론: Acri.LISA 366D 다초점 인공수정체는 우수한 원거리, 중간거리 및 근거리 시력교정 및 대비감도를 보이고 백내장 술 후 환자의 만족도를 높여 노안 교정에도 유용하리라 생각된다.
Abstract
Purpose: To evaluate near, intermediate, and distant vision, optical quality, and patient satisfaction with Acri.LISA aspheric diffractive multifocal IOL. Methods: Forty eyes of 20 patients received phacoemulsification and implantation of Acri.LISA IOL. Visual acuity was measured postoperatively at 1 week, 1 month, and 6 months. Contrast sensitivity, wavefront aberration, and visual function via questionnaire were measured at postoperative 1 month. Results: Uncorrected near, intermediate, and distanct visual acuity at 1 month were 0.09±0.14, 0.29±0.17 and 0.11±0.12, respectively. At 6 months, similar visual acuity results were measured. Total and higher-order wavefront aberration values were 0.66±0.29 and 0.24±0.08, respectively. Photopic contrast sensitivity at 1.5, 3, 6, 12, and 18 cycles/degree were 1.38±0.32, 1.73±0.24, 1.75±0.21, 1.33±0.18, and 0.77±23, respectively, and mesopic contrast sensitivity values were 1.37±0.27, 1.72±0.16, 1.63±0.14, 1.01±0.19, and 0.50±0.22. Total subjective visual function score was 3,127±354, near work was 244±36, distance work was 256±21, and night driving was 221±42. Conclusions: The Acri.LISA 366D multifocal IOL can be effective for improving patient satisfaction after cataract surgery as well as for presbyopia correction.
