Endothelial keratoplasties have become the surgical procedure of choice over full thickness penetrating keratoplasty for corneal decompensation because of endothelial dysfunction.
A retrospective data review was performed from February 2016 to April 2017 for all the patients who underwent endothelial keratoplasty in a tertiary care center for Indian Armed Forces.
A total of 161 corneal transplants were performed; endothelial keratoplasties accounted for 34 (21.1%) transplants. Most common indication was pseudophakic/aphakic bullous keratopathy followed by Ahmed glaucoma valve-related corneal decompensation and Fuchs' corneal dystrophy, respectively. Mean preoperative corneal thickness was 845.96 ± 106.9 microns. Mean lenticule thickness was 131.55 ± 42.47 microns with microkeratome for descemet stripping automated endothelial keratoplasty (DSAEK) and 174 ± 70.4 microns manually for descemet stripping endothelial keratoplasty (DSEK). Mean preoperative best-corrected visual acuity (BCVA) was 1.65 LogMAR (Snellen equivalent in meters 2/60 approx) which significantly improved to 0.82 LogMAR (Snellen equivalent in meters 6/36 approx) after surgery. In the DSAEK group, BCVA improved from 1.61 to 0.7 LogMAR, whereas in the DSEK group, the visual acuity improved from 1.7 to 0.94 LogMAR at one-month postoperative period. Postoperatively, two patients had graft detachment and had to undergo repeat DSAEK.
Study results suggest the similar trends in our tertiary care hospital as in other most advanced ophthalmic centers around the world for adoption of newer techniques of lamellar corneal transplants and their outcomes.
由于内皮功能障碍,内皮角膜移植术已成为角膜失代偿时优于全层穿透性角膜移植术的手术选择。
对2016年2月至2017年4月在一家为印度武装部队服务的三级医疗中心接受内皮角膜移植术的所有患者进行回顾性数据审查。
共进行了161例角膜移植;内皮角膜移植术占34例(21.1%)。最常见的适应证分别是人工晶状体眼/无晶状体眼大泡性角膜病变、其次是与艾哈迈德青光眼阀相关的角膜失代偿和富克斯角膜营养不良。术前平均角膜厚度为845.96±106.9微米。对于基质内剥离自动内皮角膜移植术(DSAEK),使用微型角膜刀时平均植片厚度为131.55±42.47微米,对于基质内剥离内皮角膜移植术(DSEK),手动操作时平均植片厚度为174±70.4微米。术前平均最佳矫正视力(BCVA)为1.65 LogMAR(约相当于2/60米的斯内伦视力),术后显著提高至0.82 LogMAR(约相当于6/36米的斯内伦视力)。在DSAEK组中,BCVA从1.61提高到0.7 LogMAR,而在DSEK组中,术后1个月时视力从1.7提高到0.94 LogMAR。术后,两名患者发生植片脱离,不得不再次接受DSAEK手术。
研究结果表明,在我们的三级医疗中心,采用板层角膜移植新技术及其效果的趋势与世界其他最先进的眼科中心相似。
