【摘要】 目的:比较SMILE手术与V4c ICL植入术治疗高度近视患者术后的客观视觉质量。方法:前瞻性对照研究。选取于我院行SMILE手术38例76眼及V4c ICL植入术32例64眼的高度近视患者,并按手术方式分为SMILE手术组及V4c ICL植入术组。术前,术后1wk,1、3、6mo时分别测量所有术眼的屈光度、裸眼视力(UCVA)和最佳矫正视力(BCVA),同时使用双通道客观视觉质量分析系统(OQASⅡ)获得术眼的客观散射指数(OSI)值、斯特列尔比(SR)和调制传递函数(MTF)截止频率。结果:在术后所有随访点,SMILE手术组和V4c ICL植入术组的等效球镜(SE)、UCVA和BCVA均无差异。术后1wk,1mo时,两组患者术后OSI值与术前相比均升高(P<0.01),术后3、6mo时两组OSI值恢复至术前水平且组间无差异。术后1wk两组患者MTF截止频率与术前相比下降(P<0.01),至术后1mo时恢复至术前水平且所有时间点组间均无差异(P>0.05)。结论:SMILE手术及V4c ICL植入术均能获得很好的术后视力及理想的客观视觉质量。更多还原

【Abstract】 AIM: To compare the objective optical quality of high myopic patients between SMILE and V4c ICL implantation.METHODS: This was a prospective control study. Thirty-eight patients underwent SMILE and thirty-two patients underwent V4c ICL implantation with high myopia were chosen for this study. Uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA) and refractive situation were evaluated preoperatively, at 1 wk, 1 mo, 3 mo and 6 mo postoperatively. The objective scattering index(OSI), strehl rate(SR) and modulation transfer function(MTF) cut off frequency were measured by the double-pass optical quality system at the same time.RESULTS: No significant difference of spherical equivalent(SE), UCVA and BCVA was found between SMILE group and V4c ICL implantation group at all time points. At 1 wk and 1 mo after operation, the OSI values of two groups were significantly higher than pre-operation(P<0.01). OSI values of two groups returned to baseline at 3 mo after operation. The MTF cut off frequency of both groups decreased significantly at 1 wk after operation(P<0.05) and recovered to baseline at 1 mo after operation, no significant difference was found between two group at all time points(P>0.05).CONCLUSION: Both SMILE and V4c ICL implantation can obtain good visual acuity and objective optical quality.更多还原
