【摘要】：目的评估使用3 a的FEMTO-LDV飞秒激光制瓣的稳定性。方法随机选取2010年10月和2013年5月行飞秒激光制瓣的LASIK患者各60眼,根据手术时间分为2010年组和2013年组,通过对2组患者飞秒激光所制角膜瓣的精确性、一致性、重复性进行对比分析来监测设备的稳定性。结果 2010年组、2013年组制瓣前角膜中央厚度分别为428.5～592.0(534.6±32.1)μm、495.0～618.0(539.9±25.3)μm,2010年组、2013年组所制角膜瓣厚度分别为64.0～108.0(89.1±9.1)μm、66.5～108.5(89.4±8.7)μm,两组间制瓣前角膜中央厚度及所制角膜瓣厚度比较,差异均无统计学意义(均为P0.05)。实际角膜瓣厚度与预设值之间的差值2010年组、2013年组分别为(-0.93±9.14)μm、(-0.63±8.84)μm,2组实际角膜瓣厚度与预设值之间的差值比较,差异无统计学意义(P=0.855)。在偏差±20μm以内的2010年组、2013年组患者分别为58眼、57眼,占各组总例数的96.67%和95.00%。结论不同阶段飞秒激光设备制作的角膜瓣保持了较好的精确性、一致性和重复性,设备稳定性保持良好。
[Abstract]:Objective to evaluate the stability of 3 years FEMTO-LDV femtosecond laser flap. Methods 60 eyes of LASIK patients who received femtosecond laser flap in October 2010 and May 2013 were randomly divided into 2010 group and 2013 group according to the operation time. The accuracy and consistency of corneal flap made by femtosecond laser in two groups were compared. Repeatability is compared to monitor the stability of the equipment. Results in the 2010 group, the central corneal thickness of the prevalvated cornea in the 2013 group was 428.559 2.0 渭 m, 534.6 卤32.1 渭 m, respectively. There was no significant difference in the central corneal thickness and the corneal flap thickness between the two groups (P 0.05). In the 2010 group, the corneal flap thickness in the 2013 group was 64.0 渭 m, 108.0 渭 m, 89.1 卤9.1) 渭 m, respectively (89.4 卤8.7) 渭 m. There was no significant difference between the two groups in the central corneal thickness and the corneal flap thickness (P 0.05). The difference between the actual corneal flap thickness and the preset value in the 2010 group and 2013 group was -0.93 卤9.14 渭 m and 0.63 卤8.84 渭 m respectively. There was no significant difference between the actual corneal flap thickness and the preset value in the 2013 group. In the 2010 group with deviations within 卤20 渭 m, 58 eyes and 57 eyes were in 2013, accounting for 96.67% and 95.00% of the total cases in each group. Conclusion the corneal flap produced by femtosecond laser at different stages has good accuracy, consistency and repeatability, and the stability of the device is good.
