摘要
目的通过眼前节光学相干断层扫描仪(AS-OCT)检测,研究白内障超声乳化吸除术后角膜结构的改变。方法选取行3.0mm透明角膜隧道切口白内障超声乳化术的白内障患者61例(90眼),分别于术前,术后2d、1周、1月、3月使用AS-OCT扫描角膜结构,进行角膜各项参数指标测量分析。结果术后2d观察到角膜内切口哆开56眼(62.2%),外切口哆开10眼(11.1%),后弹力层脱离27眼(30.0%)。内切口哆开术后1周较术后2d新增15.6%,术后1月较术后1周新增5.6%。后弹力层脱离均发生于切口后唇。无论有无后弹力层脱离,切口最厚处总是位于其后唇。术后各个时间点角膜切口均较术前肿胀(P<0.05),术后3月与术前相比,差异仍有统计学意义(P<0.05)。结论白内障超声乳化吸除术后会引起角膜结构的各种变化,AS-OCT能清晰观察并定量分析这些情况。
Objective To evaluate the corneal structure change after phacoemulsification by anterior segment optical coherence tomography （AS-OCT）. Methods Phacoemulsifieation with 3.0 mm clear corneal tunnel incision were performed in 61 cataract patients （90 eyes）. Corneal structure were scanned with the AS-OCT preoperatively, 2 d, 1 week, 1 month, and 3 months postoperatively respectively, and the parameters were analyzed statistically. Results Gaping at the endothelial side of the wound in 56 eyes （62.2%）, gaping at the epithelial side in 10 eyes （11.1%）, and Descemet＇s membrane detachment in 27 eyes （30.0%） were observed 2 d postoperatively. 15.6% more of the eyes had gap at the endothelial side at I week postoperative, and 5.6% more at 1 month postoperative. Descemet＇s membrane detachment happened after incision lip in all of the eyes. The thickest site of incisional cornea was located before incision lip in all of the eyes. The incisional corneal thicknesses at variable postoperative time points were thicker than that of preoperative （P〈0.05）. The incision thickness at 3 months postoperative was still significantly different from that of preoperative （P〈0. 05）. Conclusions The corneal structure changes after phacoemulsification. AS-OCT could provide sensitive and detailed observation and quantitative measurements of the changes.
