摘要

目的:比较飞秒辅助LASIK与人工晶状体植入术矫正高度近视的疗效、安全性和稳定性。方法:采用非随机对照前瞻性连续介入研究。纳入2016年1月至2017年1月在索哈格大学附属医院眼科门诊就诊的40例高度近视(≥- 6ds)患者74只眼。根据近视程度、角膜厚度和角膜断层扫描将患者分为两组。第一组20例(34眼)行植入术，第二组40例(40眼)行飞秒辅助LASIK手术。结果:第一组(ICL组)术前UCVA为(1.90±0.29)，术后UCVA为(0.27±0.21)，p值<0.000*。BCVA术前为(0.526±0.272)，BCVA术后为(0.217±0.128)，p值<0.001*，说明BCVA术后优于术前预期。球面误差由术前的(-13.576±3.945)降至术后的(-0.0385±0.821)，p值<0.000*。柱形误差术前为(-1.134±0.617)，术后为(-0.352±0.250)，p值<0.000*。术前球面等效为(-15.173±4.079)，术后球面等效为(-0.269±0.787)，p值<0.000*。术前厚测为(518.153±22.981)，术后厚测为(521±22.304)，p值<0.140。第二组(飞秒辅助LASIK)术前UCVA为(1.42±0.27)，术后UCVA为(0.366±0.21)，p值<0.000*。BCVA术前术后无明显差异。术前球面误差为(-8.398±1.733)，术后球面误差为(-0.796±1.186)，p值<0.000*。术前圆柱误差平均值(1.648±0.838)校正为(-0.765±0.423)，p值< 0.005。术前球面等效为(-9.213±1.899)，术后球面等效为(-0.935±1.11)，p值<0.000*。术前厚测为(535.111±26.33)，术后厚测为(419.88±43.063)，p值<0.000*。结论:对于高度近视患者，植入式晶体与飞秒辅助LASIK均具有较高的疗效和安全性，但植入式晶体的稳定性更好。

COMPARISON OF CLINICAL OUTCOMES AFTER FEMTOSECOND ASSISTED LASER IN SITU KERATOMILEUSISAND IMPLANTABLE COLLAMER LENS IMPLANTATION FOR CORRECTION OF HIGH MYOPIA

Purpose: To compare efficacy, safety and stability of Femtosecond assisted LASIK and implantable collamer lens implantation in correction of high myopia. Methods: This study was nonrandomized comparative prospective consecutive interventional study. It included 74 eyes with high myopia (≥ -6 Ds) of 40 patients attended to the outpatient ophthalmic clinic of Sohag university hospitals from the period from Jan.2016 to Jan.2017. The patients were divided into two groups depending on: Degree of myopia, corneal thickness and corneal tomography. The first group (34 eyes) of 20 patients were subjected to implantable collamer lenses implantation and the second group (40 eyes) of 40 patients were subjected to femtosecond assisted LASIK. Results: Group one (ICL group) showed UCVA preoperative was (1.90±0.29) and UCVA postoperative was (0.27±0.21) with (p-value<0.000*). BCVA preoperative was (0.526±0.272) and that of BCVA postoperative was (0.217±0.128) with (p-value<0.001*), which means that BCVA postoperative was better than what was expected from the BCVA preoperative. Spherical error decreased from (-13.576±3.945) preoperative to (-0.0385±0.821) postoperative with (p-value<0.000*).Cylindrical error preoperative was (-1.134±0.617) and postoperative was (-0.352±0.250) with (p-value<0.000*).Spherical equivalent preoperative was (-15.173± 4.079) and that of postoperative was (-0.269±0.787) with (p-value<0.000*). Pachymetry preoperative was (518.153±22.981) and postoperative was (521± 22.304) with (p-value <0.140). Group two (Femtosecond assisted LASIK) UCVA preoperative was (1.42±0.27) and UCVA postoperative was (0.366±0.21) with (p-value<0.000*).There wasnt significant difference between BCVA preoperative and postoperative. Spherical error preoperative was (-8.398±1.733) and postoperative (-0.796±1.186) with (p-value<0.000*). Cylinder error mean value preoperative was (1.648±0.838) corrected to (-0.765±0.423) with (p-value< 0.005). Spherical equivalent preoperative was (-9.213±1.899) and that of postoperative is (-0.935±1.11) with (p-value<0.000*). Pachymetry preoperative was (535.111±26.33) and postoperative (419.88± 43.063) with (pvalue<0.000*). Conclusion: Both implantable collamer lens and Femtosecond assisted LASIK proved high efficacy and safety but implantable collamer lens showed more stability for high myopic patients.
