摘要
目的探讨经上皮准分子激光角膜切削术治疗近视的临床疗效。方法以汕尾市第二人民医院2013-01—2016-06间收治的120例近视患者为例,根据眼屈光度不同分为两组,均行经上皮准分子激光角膜切削术治疗。观察组70例患者屈光度为-6.25^-10.00D,对照组50例患者为≥-10.25D。观察两组患者术后发生并发症的情况,随访半年,就两组患者视力、屈光度、角膜上皮下基质浑浊变化情况进行比较。结果观察组患者并发症发生率4.29%与对照组的10.00%比较,差异无统计学意义(P>0.05)。随访半年发现,观察组患者达到最佳矫正视力的为64例,屈光度均在预期矫正度以内的57例,角膜上皮下基质浑浊在0~0.5级的70例,均显著优于对照组,差异有统计学意义(P<0.05)。观察组患者治疗后满意度评分(92.2±6.8)分,显著高于对照组的(84.3±11.0)分,差异有统计学意义(P<0.05)。结论经上皮准分子激光角膜切削术治疗近视的效果较好,但针对屈光度≥-10.25D的患者疗效不如-6.25^-10.00D的患者。
Objective To investigate the clinical effect of epithelial excimer laser keratectomy for myopia. Methods 120 patients with myopia in the hospital from January,2013 to June,2016 were divided into two groups according to the different diopter of the eyes. Diopter of 70 patients of the observation group was-6. 25 ^-10. 00 D,and 50 patients of the control group was≥-10. 25 D.The complications of the two groups were observed. After six months＇ follow-up,the visual acuity,refractive index and the changes of corneal stroma opacity of the two groups were compared. Results The complication rate of the observation group is 4. 29% compared with 10. 00% of the control group. The difference is not statistically significant（ P〉0. 05）. After half year＇s follow-up,64 patients in the observation group reached the best corrected visual acuity,57 cases have diopter in the expected correction degree,and 70 cases have corneal opacity under the grade 0 ~ 0. 5. The observation group is significantly better than the control group,and the difference is statistically significant（ P〈0. 05）. Satisfaction score of patients in the observation group after treatment is（ 92. 2 ± 6. 8）points,which is significantly higher than the control group（ 84. 3 ± 11. 0） points. The difference is statistically significant（ P〈0. 05）. Conclusion Transepithelial photorefractive keratectomy for myopia is better,but the effect of the patients with diopter≥-10. 25 D is less than that of-6. 25 ^-10. 00 D patients.
