【摘要】：[目的]比较微小切口基质透镜切除术(SMILE)和前弹力层下激光角膜磨镶术(SBK)治疗近视及散光手术前后患者疗效的变化。 [方法]选取我院行SMILE手术和SBK手术的近视患者共29人(分别30只眼和27只眼),对比两组术后1月、3月的屈光度、裸眼视力、最佳矫正视力、对比敏感度和波前像差。前提：两组术前屈光度、最佳矫正视力、各空间频率无眩光及有眩光条件下对比敏感度、总高阶像差、球差的差异均无显著性。 [结果](1)术后1月和3月两组的视力和屈光度数无统计学差异,其有效性、安全性、可预测性、稳定性的差异均无显著性(P0.05。(2)术后月和3月两组在个别空间频率无眩光及有眩光条件下对比敏感度较术前显著降低(P0.05)；SBK组影响的空间频率多于SMILE组。(3)术后1月和3月两组的总高阶像差、球差均较术前显著增大，但SMILE组高阶像差和球差较SBK组小(P0.05)。 [结论]SMILE及SBK矫正近视和散光均安全有效。SMILE组术后个别空间频率的对比敏感度优于SBK组。SMILE组较SBK组更少地引入高阶像差,尤其是球差。SMILE组术后患者视觉质量更好。
[Abstract]:[objective] to compare the effect of mini-incision matrix lens resection (Smile) and anterior elastic layer laser keratomileusis (SBK) on myopia and astigmatism. [methods] A total of 29 myopia patients (30 eyes and 27 eyes) who underwent Smile and SBK were selected. The diopter, uncorrected visual acuity, best corrected visual acuity, contrast sensitivity and wavefront aberration were compared between the two groups at 1 month and 3 months after operation. Premise: there were no significant differences in preoperative refraction, best corrected visual acuity, no glare in each spatial frequency and contrast sensitivity, total high-order aberration and spherical aberration in the two groups under the condition of glare. [results] (1) there was no significant difference in visual acuity and diopter between the two groups at one month and three months after operation. There was no significant difference in stability between the two groups (P0.05. (2) the contrast sensitivity of the two groups under the condition of no glare and no glare in individual spatial frequency was significantly lower than that before operation (P0.05). (3) the total high order aberration and spherical aberration in SBK group were significantly higher than those in preoperative group, but higher order aberration and spherical aberration in Smile group were smaller than those in SBK group (P0.05). [conclusion] Smile and SBK are safe and effective in correcting myopia and astigmatism. The contrast sensitivity of individual spatial frequency in SMILE group is better than that in SBK group, especially in SMILE group. The visual quality of SMILE group is better than that of SBK group.
