목적: 굴절성 비구면 다초점 인공수정체(Lentis MplusⓇ LS-313)를 삽입한 환자들의 시각적 및 광학적 임상결과를 알아보고자 하였다. 대상과 방법: Lentis MplusⓇ LS-313를 삽입한 53명 68안을 대상으로 술 후 1일, 2주, 1∙3∙6개월에 나안 원거리∙중간거리∙근거리시력, 굴절오차 및 술 후 3개월에 Optical Quality Analysis System Ⅱ (OQAS II)를 이용한 시기능 검사, 고위수차를 측정하였으며만족도 설문조사를 시행하였다. 결과: 술 후 6개월째 평균 나안시력은 원거리 0.06 ± 0.07, 중간거리 63 cm 0.18 ± 0.14, 중간거리 100 cm 0.15 ± 0.13, 근거리0.11 ± 0.10 (logMAR)이었다. OQAS II 검사상 평균 객관적 산란지수(Objective scatter index, OSI)는 1.20 ± 0.69, 변조전달기능(MTF cut off value)은 34.15 ± 9.53 cpd, Strehl 비율은 0.17 ± 0.05이었고 위조절력은 3.09 ± 0.25D였다. 고위수차는 5 mm 0.61± 0.14, 6 mm 1.07 ± 0.20이었다. 술 후 82%에서 만족하였고 71%가 추천하였으며 야간시력장애 호소는 24%였다. 결론: Lentis MplusⓇ LS-313는 우수한 원거리, 중간거리 및 근거리 시력을 보였고 높은 만족도를 보여서 백내장과 노안을 같이 교정할 수 있는 유용한 인공수정체로 생각한다.
Abstract
Purpose: To evaluate the clinical outcomes of patients with refractive aspheric multifocal intraocular lens (IOL) (Lentis Mplus®LS-313) implantation. Methods: Sixty-eight eyes of 53 patients received refractive aspheric multifocal IOL implantation. Uncorrected visual acuity(UCVA) at a long distanc, as well as intermediate and near distances were measured on the first day, after two weeks, and duringthe first, third and sixth months postoperatively. Optical quality was evaluated using the Optical Quality Analysis System II(OQAS II). High-order aberrations (HOA) and patient satisfaction questionnaires were evaluated at three months post-operation. Results: At the six-month postoperative visit, the mean UCVA at a long, two intermediate (63 cm, 100 cm) and a near distancewere 0.06 ± 0.07, 0.18 ± 0.14, 0.15 ± 0.13 and 0.11 ± 0.10 log MAR, respectively. The means of the objective scatter index, modulationtransfer function (MTF) cut off value, Strehl ratio and pseudo-accommodation range measured by OQAS II were 1.20 ±0.69, 34.15 ± 9.53 cdp, 0.17 ± 0.05 and 3.09 ± 0.25 D, respectively. HOA of 5 mm and 6 mm were each 0.61 ± 0.14 and 1.07 ±0.20, respectively. Eighty-two percent of patients were satisfied with the postoperative results, and 71% of the patients reportedthat they would recommend the procedure to others, while 24% of patients reported moderate or severe visual disturbance atnight. Conclusions: Implantation of the refractive aspheric multifocal IOLs in patients with cataracts provided excellent distant, intermediate,and near visual outcomes and high patient satisfaction as well as presbyopia correction.
