목적 : To present the clinical outcomes of Small Incision Lenticule Extraction including visual quality analysis in patients with myopia in Korea.
방법 : Medical record of 228 eyes of 116 patients who got SMILE (Small Incision Lenticule Extraction) operation from May 2014 to Feb 2015 in HanGil Eye Hospital LASIK center was analyzed retrospectively. The patients were followed up at 1 day, 1 week, 1 month, 3 months after the operation and visual acuity, intraocular pressure, visual quality assessed using Optical Quality Analysis System II (OQAS IIⓇ, Visiometrics, Castelldefels, Barcelona, Spain) were measured at each visit. Every value was analyzed and compared with preoperative values.
결과 : The subject was 228 eye of 116 patients with 26.84 ± 6.44 years old in average. At the 3rd postoperative months, the uncorrected distant visual acuity was 0.02 ± 0.04 in LogMAR, the postoperative IOP was 11.65 ± 2.49 mmHg and OSI score was 0.85 ± 0.43. The efficacy of refractive surgery was 0.97 ± 0.11, the safety was 0.99 ± 0.10, and predictability was 99.56% and 100.00% at the range of ±0.5 diopter and ± 1.0 diopter each. Suction loss happened in one eye and converted into photorefractive keratectomy. One eye received PRK due to remnant myopia observed 1 month after the operation.
결론 : SMILE operation showed favorable clinical outcome in terms of efficacy, safety and predictability. Intraocular pressure and visual quality had improved gradually throughout 3 months of the postoperative period. PRK (Photorefractive Keratectomy) can be a good treatment option in cases of incomplete SMILE operation or postoperative myopic regression.
