【摘要】：目的评价Ziemer’s Femto LDV飞秒激光制瓣联合准分子激光角膜原位磨镶术(LASIK)治疗不同屈光度近视的临床疗效。方法将行Femto LDV制瓣的LASIK近视患者203例共401眼按术前屈光度分成3组,A组:-0.5~-6.0 D,284眼;B组:-6.25~-10.0 D,107眼;C组:-10.25~-14 D,10眼。观察术后12个月内其裸眼视力、矫正视力、屈光度及术后并发症的发生。结果虽然3组术后3个月的裸眼视力达0.5以上者均为100%,但1.0以上者分别为100.0%、99.1%及70.0%,其中C组患者显著低于A、B组(P0.05)。而且C组患者术后12个月裸眼视力逐渐出现低于术前的最佳矫正视力的发生率明显高于A、B组(P0.05),但3组的术后最佳矫正视力均无明显下降(P0.05)。术后12个月各组平均屈光度A组为(-0.19±0.43)D,B组(-0.37±0.63)D,C组(-1.02±1.16)D,其中≤±0.5 D的分别为98.9%、83.2%和40.0%(C组明显低于A、B组,P0.05)。所有患者基质床切削区均匀,偏离中心率低,角膜后表面高度差异无统计学意义,泪膜破裂时间、眼压差异均无统计学意义(P0.05),未见严重并发症发生。结论使用Femto LDV制瓣的LASIK对于不同近视度数的患者均有好的治疗效果,术后视力好,预测性高,效果稳定及安全性高等,但对于超高度近视患者术后12个月视力预测性明显低于其他近视患者。
[Abstract]:Objective to evaluate the clinical effect of Ziemer's Femto LDV femtosecond laser flap making combined with excimer laser in situ keratomileusis (LASIKK) in the treatment of myopia with different diopters. Methods 203 patients with LASIK myopia treated with Femto LDV flap were divided into preoperative diopters. The visual acuity was observed in 10 eyes of group C (10% -10.25) and 10 eyes of group C (10 eyes), and the visual acuity of 10 eyes was observed within 12 months after operation. Corrected vision, Results although the uncorrected visual acuity of 3 months after operation was 100 in all the 3 groups, it was 100.099.1% and 70.0% respectively in those with 1.0 or more than 1.0, among which the patients in group C were significantly lower than those in group A (P 0.05), and the patients in group C were 12 years after operation. The incidence of uncorrected visual acuity gradually lower than that of preoperative best corrected visual acuity (BCVA) in group A was significantly higher than that in group A (P 0.05), but there was no significant decrease in postoperative best corrected visual acuity (BCVA) in all three groups. 12 months after operation, the mean diopter of group A was -0.19 卤0.43 卤0.43 卤0.37 卤0.63DC.
