方法：收集我院2018-10/11的白内障日间手术的患者149例149眼，完成白内障超声乳化摘除联合人工晶状体植入术，观察患者术眼术前、术后2h，1d，1wk的BCVA和眼压并进行术前术后的对比，在裂隙灯下观察其角膜水肿情况、是否有人工晶状体脱位和其他并发症，对术前和术后高眼压率、低眼压率进行比较。

结果：术眼术前与术后2h BCVA，术后2h与术后1d BCVA，术后1d与术后1wk的BCVA均有差异(P<0.05)，呈逐渐改善的趋势。患者术眼术前与术后2h，1d眼压均无差异(P>0.05)，但术后1wk的眼压均低于术前、术后2h，1d的眼压(P<0.05)。术后2h出现高眼压的比例高于术前、术后1d，1wk。术后1wk未发现患者出现眼部并发症。

结论：白内障日间手术患者术后1wk视力、眼压和角膜水肿均恢复良好，在术后2h容易出现高眼压，进行视力、眼压和裂隙灯显微镜检查，较为安全，可对出现高眼压的患者作对症处理。

METHODS: We collected cataract patients receiving day surgery from October to November 2018. They underwent phacoemulsification combined with intraocular lens(IOL)implantation. 149 patients(149 eyes)were included. Before the surgery, and 2h, 1d, 1wk after the surgery, we measured and compared their best corrected visual acuity(BCVA)and IOP, observing whether they had the corneal edema, IOL dislocation or other complications with slit lampmicroscope. We also compared the percentage of high IOP, low IOP before and after surgery.

RESULTS: BCVA before and 2h after surgery, BCVA 2h and 1d after surgery, and BCVA 1d and 1wk after surgery were statistically different, showing a gradually improving trend(P<0.05). There was no significant difference between IOP before surgery and 2h after surgery or 1d after surgery(P>0.05), but the IOP 1wk after surgery was lower than that before surgery, 2h after surgery and 1d after surgery(P<0.05). The percentage of high IOP 2h after surgery was significantly higher than that before surgery, 1d after surgery and 1wk after surgery. No ocular complication was found 1wk after surgery.

CONCLUSION: The visual acuity, IOP and corneal edema of the patients recovered 1wk after day cataract surgery, and high IOP was easy to happen 2h after surgery. Visual acuity, IOP and slit lamp microscope examination were safe, and corresponding treatment could be given to patients with high IOP.
