목적: 새로운 굴절교정술 장비인 SCHWIND ATOS femtosecond laser (SCHWIND eye-tech-solutions, Kleinostheim, Germany)를이용한 스마트사이트(SmartSight®)수술의 단기 임상 결과를 보고하고자 한다. 대상과 방법: 2022년 4월부터 9월까지 스마트사이트수술을 받고 3개월 이상 경과 관찰이 가능한 170명 338안의 의무기록을 후향적으로 분석하였다. 수술 전 및 수술 후 1일, 1주, 1개월, 3개월의 시력, 안압 및 굴절 결과를 추적 관찰하였다. 결과: 수술 전 나안시력은 logarithm of minimum angle or resolution 1.26 ± 0.33, 구면렌즈대응치는 -4.52 ± 1.77디옵터였다. 수술3개월 후 나안시력은 0.02 ± 0.04, 구면렌즈대응치는 -0.12 ± 0.22디옵터였다. 수술 3개월 후 굴절교정술의 효율성은 0.99 ± 0.11, 안정성은 1.00 ± 0.05였으며 굴절교정예측도는 ± 0.5디옵터와 ± 1.0디옵터 범위에 대해 각각 97%와 100%였다. 결론: 스마트사이트수술은 굴절교정술의 효율성과 안정성, 예측도 측면에서 만족할 만한 초기 임상 결과를 보였다.
Abstract
Purpose: To evaluate the clinical outcomes of a new refractive corneal lenticule extraction method (SmartSight) using a Schwind ATOS femtosecond laser (Schwind Eye-Tech-Solutions, Kleinostheim, Germany). Methods: The medical records of 338 eyes of 170 patients who underwent SmartSight treatment from April to September 2022 and were followed-up for at least 3 months were retrospectively analyzed. The patients were followed-up at 1 day, 1 week, and 1 and 3 months after operation. Refraction, visual acuity, and intraocular pressure were measured at each visit. Results: Preoperatively, the uncorrected distant visual acuity was 1.26 ± 0.33 logarithm of minimum angle or resolution (logMAR) and the spherical equivalent was -4.52 ± 1.77 diopters. The 3-month, postoperative, uncorrected distant visual acuity was 0.01 ± 0.03 logMAR and the spherical equivalent was -0.12 ± 0.22 diopters. The 3-month data were as follows: efficacy of refractive surgery, 0.99 ± 0.11; safety, 1.00 ± 0.05; predictabilities at ±0.5 and ± 1.0 diopters, 97% and 100%, respectively. Conclusions: Myopic astigmatism correction using the SmartSight method was effective, safe, and predictable in terms of visual outcomes.
