目的研究飞秒激光小切口基质透镜取出术(small incision lenticule extraction,SMILE)治疗近视性屈光参差的治疗效果。方法采用回顾性研究,近视患者19例30只眼,采用SMILE矫正,记录术前,术后1天,术后1周,术后1、3、6个月的裸眼视力、最佳矫正视力、屈光度、屈光参差程度进行对比研究。结果 30只眼术后裸眼视力均显著提高,术后1天、1周、1个月裸眼视力呈逐渐上升趋势(P<0.05),而术后1、3、6个月裸眼视力稳定,差异均无统计学意义(P>0.05);所有患者,按近视程度较高眼及近视程度较低眼分别统计,术后1天,1周,1、3、6个月的双眼裸眼视力之间无统计学差异(P>0.05);术后3只眼最佳矫正视力提高一行,未出现最佳矫正视力下降的情况;所有患者术后屈光参差均得到有效矫正,术后1天,1周,1、3、6个月同一患者的近视程度较高眼与近视程度较低眼的屈光度无统计学差异(P>0.05);术后双眼屈光度差值平均为(0.40±0.27)D。结论 SMILE治疗近视性屈光参差术后视力好、屈光状态稳定、不受术前双眼近视程度差异的影响,是一种安全、有效、稳定性好的屈光参差矫正方法。
Objective To study the therapeutic effect of small incision lenticule extraction (SMILE) for treatment of myopic anisometropia. Methods A retrospective study was conducted in 19 eyes of 30 patients with myopia. SMILE was used for correction. The preoperative and postoperative 1 day, postoperative 1 week, postoperative 1, 3 and 6 months postoperative uncorrected visual acuity, best corrected visual acuity, Diopter, anisometropia degree of contrast study. Results The uncorrected visual acuity was significantly increased in all 30 eyes. The uncorrected visual acuity was gradually increased at 1 day, 1 week and 1 month after operation (P <0.05), while visual acuity was stable at 1, 3, and 6 months after operation (P> 0.05). All the patients were statistically analyzed according to the degree of myopia and the degree of myopia. The visual acuity of uncorrected visual acuity of the eyes after 1 day, 1 week, 1, 3 and 6 months No significant difference (P> 0.05); 3 eyes of best corrected visual acuity increased by one line, did not appear the best corrected visual acuity decreased; all patients with anisometropia have been effectively corrected, 1 day after surgery, 1 There was no significant difference in the refraction of the eye in the same patient at 1, 3, and 6 months (P> 0.05). The average difference of binocular refractive power was (0.40 ± 0.27) D after operation. Conclusions SMILE is a safe, effective and stable method of correcting anisometropia with good visual acuity and stable refractive condition, which is not affected by the difference of myopia before operation in myopic anisometropia.
