Monovision LASIK的临床研究

目的:研究Monovision LASIK的临床疗效。方法:回顾性分析来我院接受LASIK手术屈光不正的患者110例(220眼),年龄40岁以上,术后随访1a,术后接受问卷评估。分析术前及术后1a的裸眼视力(远视力、近视力)、屈光等数据,结合问卷评估结果进行统计学分析。结果:78例接受Monovision LASIK手术,32例患者接受双眼完全矫正手术。Monovision组和完全矫正组患者术后裸眼远视力分别为1.21±0.13,1.19±0.15,两者比较统计学上差异无显著性(P=0.35)。Monovision组术后裸眼近视力(0.68±0.25)好于完全矫正组(0.43±0.21,P=0.04),两组术后屈光参差分别为1.41±0.26D,0.12±0·11D,两两比较统计学上具有显著性差异(P=0.03)。术后满意度Monovision组与完全矫正组分别为87%与85%,统计学上无显著性差异(P=0.65)。术后驾车、行走、运动等不戴镜分别为91.5%,97.2%,差异无统计学意义(P=0.55)。术后近距离工作从不佩戴老视眼镜分别为48.6%,15.6%(P=0.03),差异具有统计学意义。结论:Monovision LASIK是一种矫治老视的有效方法。

Clinical research on monovision LASIK

AIM:To evaluate the clinical effects of monovision after laser in situ keratomileusis (LASIK). ·METHODS: A retrospective study on 110 patients (220 eyes, age > 40 years), who had LASIK with a follow-up one year, were done. All patients were asked to complete a questionnaire. Data including uncorrected visual acuity, refractions combined with the results of questionnaires were analyzed statistically. ·RESULTS: In 78 patients accepted monovision LASIK, 32 patients accepted full correction. Uncorrected visual acuity of monovision group and full correction group were 1.21±0.13 and 1.19±0.15. There was no significant difference between them (P=0.35). Uncorrected near visual acuity of monovision group (0.68±0.25) was better than that of full correction group (0.43±0.21,P=0.04). Anisometropia of monovision group and full correction group were 1.41±0.26D and 0.12±0.11D, the difference had statistical signify (P=0.03). Satisfaction rate of two groups were 87% and 85%(P=0.65). Never need for Distance Glasses of two groups were 91.5% and 97.2%, the difference was not statistically significant (P=0.55). Never need for near Glasses of two groups were 48.6% and 15.6%, and there was no statistically significant difference (P=0.03).·CONCLUSION: Monovision LASIK is a viable solution to correcting presbyopia.
