PURPOSE
To observe the first 24-hour (h) outcomes of the small incision lenticule extraction procedure (SMILE) for myopia and myopic astigmatism.
METHODS
Fifty-three eyes (27 patients) scheduled for SMILE were followed immediately (0 h), 2, 4, 6, and 24 h after SMILE. Uncorrected visual acuity (UCVA), conjunctival congestion, pain level, and corneal edema, thickness, and densitometry were recorded.
RESULTS
At 2 h after SMILE, 15.1% of eyes had ≤0.1 LogMAR UCVA; this increased to 62.3%, 98.1%, and 100% at 4, 6, and 24 h, respectively. Some eyes (33.96%) had mild corneal edema immediately after surgery. No 6 h postoperative edema was observed. In the first 24 h after SMILE, corneal thickness gradually decreased. Postoperative corneal densitometry values were significantly higher than preoperative values but gradually decreased during the first postoperative 24 h.
CONCLUSIONS
In the first postoperative 24 h, UCVA and corneal status (edema and densitometry) improved quickly.
目的
观察飞秒激光小切口基质透镜切除术（SMILE）治疗近视及近视散光的最初24小时的效果。
方法
对计划接受SMILE手术的53只眼（27例患者）在SMILE术后即刻（0小时）、2小时、4小时、6小时和24小时进行随访。记录裸眼视力（UCVA）、结膜充血、疼痛程度以及角膜水肿、厚度和密度测量值。
结果
SMILE术后2小时，15.1%的眼UCVA≤0.1 LogMAR；在4小时、6小时和24小时时分别增至62.3%、98.1%和100%。部分眼（33.96%）术后即刻出现轻度角膜水肿。术后6小时未观察到水肿。SMILE术后的最初24小时内，角膜厚度逐渐降低。术后角膜密度测量值显著高于术前值，但在术后最初24小时内逐渐降低。
结论
术后最初24小时内，UCVA和角膜状态（水肿和密度测量）迅速改善。
