目的:评估SCHWIND AMARIS准分子激光在LASEK术中矫治远视手术中的有效性,安全性和可预测性。
方法:回顾性研究LASEK术联合使用丝裂霉素C矫治远视患者33例66眼,平均年龄35.42±1.12岁(范围 18~56a)。每位患者予SCHWIND AMARIS准分子激光行LASEK术。术后对其可预测性、安全性、有效性及主观验光情况进行评估,并分析客观验光、裸眼视力、最佳矫正视力及不良反应。
结果:平均屈光度为3.2±1.6D(0~7D),术前及术后平均等效球镜分别为2.34±1.76D(-1.25~7D)及0.30±0.84D(-0.2~0.8D)(P=0.001)。术后6~12mo,平均远视为0.63±0.84D(-1.75~2.76D)。平均散光度为0.68±0.43D(0~2D),61眼(78.2%)和31眼(39.7%)散光度分别在±1D和±0.50D范围内。安全指数和有效性指数分别为1.08和1.6。
结论:应用SCHWIND AMARIS准分子激光联合丝裂霉素C行LASEK术矫治远视具有良好的视觉和屈光结果,而且无严重并发症。

[Abstract]
AIM: To evaluate the efficacy, safety and predictability of laser-assisted sub-epithelial keratectomy(LASEK)for the correction of hyperopia using the SCHWIND AMARIS platform.
METHODS: This retrospective single-surgeon study includes 66 eyes of 33 patients with hyperopia who underwent LASEK with mitomycin C(MMC). The median age of patients was 35.42±1.12y(ranging 18 to 56y). In each patient LASEK was performed using SCHWIND AMARIS excimer laser. Postoperatively clinical outcomes were evaluated in terms of predictability, safety, efficacy, subjective and objective refractions, uncorrected visual acuity(UCVA), best spectacle-corrected visual acuity(BSCVA)and adverse events.
RESULTS: The mean baseline refraction was 3.2±1.6 diopters(D)(ranging 0 to 7 D). The mean pre-operative and postoperative spherical equivalent(SE)were 2.34±1.76(ranging -1.25 to 7 D)and 0.30±0.84(ranging -0.2 to 0.8 D)respectively(P=0.001). The mean hyperopia was 0.63±0.84 D(ranging -1.75 to 2.76 D)6 to 12mo postoperatively. Likewise, the mean astigmatism was 0.68±0.43 D(range 0 to 2 D)with 51(77.3%)and 15(22.7%)eyes within ±1 and ±0.50 D respectively. The safety index and efficacy index were 1.08 and 1.6 respectively.
CONCLUSION:LASEK using SCHWIND AMARIS with MMC yields good visual and refractive results for hyperopia. Moreover, there were no serious complications.
