【摘要】: 目的:从视觉质量的角度评价融合分离手术治疗中年近视患者的疗效。 方法:选取年龄35~45岁的近视患者100例,等效球镜为-2.00D~-12.00D,术前最佳矫正视力≥1.0。随机分为两组:50例施行常规的LASIK为对照组(A组);50例施行融合分离手术(在LASIK中应用monovision方式;即主导眼全矫正视远,非主导眼低矫视近)为治疗组(B组)。分别测量两组患者手术前后单眼调节幅度的变化,测量术前双眼戴镜及术后半个月、1个月、3个月双眼裸眼远视力、近视力、立体视、对比敏感度,并在术后3个月对所有患者进行主观视觉质量及满意度问卷调查。行两组间及组内的比较及分析。 结果:(1)两组间术后各时间点双眼远视力无统计学差异(P0.05);两组间术后各时间点双眼近视力有统计学差异(P0.05)。(2)两组间各时间点双眼对比敏感度无统计学差异(P0.05),术后半个月各频率段两组均有下降,至术后1~3个月逐渐恢复,达到或超过术前水平。(3)两组间术后各时间点立体视无统计学差异(P0.05),术后半个月两组立体视均有下降趋势,术后1~3个月逐渐恢复,但仍低于术前。(4)B组术后半个月主导眼及非主导眼调节幅度较术前有明显的下降(P0.05),此后逐渐恢复,至术后1~3个月时仍低于术前(P0.05)。(5)所有患者术后均无视物变形及色觉改变或失真。术后3个月A组有10例患者(22.7%)需戴阅读眼镜,而B组患者均不需戴阅读眼镜;术后3个月患者视远满意度两组无统计学差异(P0.05);视近满意度两组有统计学差异(P0.05)。 结论:融合分离手术治疗中年患者近视疗效明显,优于常规LASIK手术,进一步提高了患者的视觉质量。
[Abstract]:Objective: to evaluate the efficacy of fusion separation surgery in the treatment of middle-aged myopia from the point of view of visual quality. Methods: 100 myopia patients aged 35 ~ 45 years were selected. The equivalent spherical lens was -2.00 DX -12.00 D.The preoperative best corrected visual acuity (BCVA) was 1.0 or better. Two groups of 50 cases were randomly divided into two groups: control group (n = 50) and control group (group A, n = 50) were treated with fusion and separation surgery (monovision mode was used in LASIK; that is, total correction of far distance in dominant eye, low corrected vision of non-dominant eye) was performed in group B as treatment group. The changes of the amplitude of monocular adjustment before and after operation were measured in both groups. The distance visual acuity, near vision, stereopsis, contrast sensitivity were measured before and after operation, half a month, 1 month, 3 months after operation. The subjective visual quality and satisfaction were investigated 3 months after operation. Comparison and analysis were made between the two groups and within groups. Results: (1) there was no significant difference in distant visual acuity between the two groups at each time point after operation (P 0.05); there was a significant difference in the near visual acuity between the two groups (P < 0.05); there was no significant difference in the contrast sensitivity between the two groups at different time points (P 0.05); there was no significant difference in the contrast sensitivity between the two groups (P 0.05), but there was no significant difference between the two groups (P < 0.05). The frequency of each month decreased in both groups. By 1 ~ 3 months after operation, there was no significant difference in stereopsis between the two groups (P < 0.05). The stereopsis of the two groups had a downward trend at half a month after operation, and gradually recovered 1 ~ 3 months after operation. But the adjustment amplitude of dominant eye and non-dominant eye in group B was significantly lower than that in group B (P 0.05), and then recovered gradually, and was still lower than that in group B 1 ~ 3 months after operation (P 0.05) all the patients ignored the distortion of objects and the change or distortion of color perception after operation. Three months after operation, 10 patients in group A need to wear reading glasses, while none in group B need to wear reading glasses, but there is no significant difference in distant satisfaction between the two groups at 3 months after operation (P 0.05), and there is a statistical difference between the two groups in the degree of near vision satisfaction (P 0.05). Conclusion: fusion separation surgery is more effective than conventional LASIK in the treatment of myopia in middle aged patients, and further improves the visual quality of the patients.
