To evaluate two-year results of small-incision lenticule extraction (SMILE) for correction of high myopia.
Forty-five eyes of 35 patients with mean spherical equivalent (SE) of -7.10±0.95 D who underwent routine SMILE by a single surgeon and were followed for at least 2 years were analyzed by retrospective chart review. SMILE was performed with a Visumax femtosecond laser (Carl Zeiss Meditec, Jena, Germany). Follow-up intervals were at 1, 6, 12, and 24 months after surgery. Uncorrected and best corrected distance visual acuity (CDVA), corneal wavefront measurements, and all complications were recorded.
After 2 years, 86% of eyes with plano target had an uncorrected distant visual acuity (VA) of 20/20 or better. Two percent of eyes lost 1 line of CDVA, while 32% gained 1 line. The mean SE after 2 years was -0.30±0.50 D. Corneal total high-order aberrations (HOA) increased from 0.43 to 0.92 μm at postoperative 12 months. There were metallic foreign bodies at the corneal interface in 1 eye of 1 patient which caused no decrease in VA.
SMILE for high myopia seems safe and effective in light of two-year follow-up results. The procedure caused a moderate increase in HOA.
评估小切口透镜切除术(SMILE)矫正高度近视的两年效果。
通过回顾性病历审查,分析了35例患者的45只眼,这些患者平均等效球镜度(SE)为-7.10±0.95 D,由一名外科医生进行常规SMILE手术,并随访至少2年。使用Visumax飞秒激光(德国耶拿卡尔蔡司医疗技术公司)进行SMILE手术。术后随访时间为1、6、12和24个月。记录未矫正和最佳矫正远视力(CDVA)、角膜波前测量结果以及所有并发症。
两年后,目标屈光度为平光的眼中,86%的未矫正远视力(VA)达到20/20或更好。2%的眼睛CDVA下降1行,而32%的眼睛CDVA提高1行。两年后的平均SE为-0.30±0.50 D。术后12个月时,角膜总高阶像差(HOA)从0.43增加到0.92μm。1例患者的1只眼中角膜界面有金属异物,未导致视力下降。
根据两年的随访结果,SMILE治疗高度近视似乎安全有效。该手术导致HOA适度增加。
