微型板层角膜刀与飞秒激光制作角膜瓣对患者视力及角膜瓣厚度的影响

目的：比较微型板层角膜刀与飞秒激光制作角膜瓣对患者视力及角膜瓣厚度的影响。

方法：将2014-06/2015-05期间本院收治的近视屈光手术治疗的患者120例240眼，根据术式不同分为A组(微型板层角膜刀组)60例120眼和B组(飞秒激光组)60例120眼，然后将两组患者治疗后不同时间的视力情况及角膜瓣厚度相关指标进行比较。

结果：治疗后不同时间两组的视力情况差异无统计学意义(均P>0.05)，而治疗后不同时间B组的角膜瓣厚度相关指标均好于A组，差异有统计学意义(均P<0.05)，两组治疗后的评估指标间差异均有统计学意义(均P<0.05)。

结论：飞秒激光制作角膜瓣对患者角膜瓣厚度的影响明显好于微型板层角膜刀，两种治疗方式对视力的影响差异不明显。

Influence of microkeratome and femtosecond laser on vision and corneal flap thickness used in corneal flap making

AIM: To study and compare the influence situation of corneal flap made by microkeratome and femtosecond laser for the vision and corneal flap thickness in patients.

METHODS: Totally 120 patients(240 eyes)with myopic refractive surgery in our hospital from June 2014 to May 2015 were randomly divided into Group A(microkeratome group)with 60 cases(120 eyes)and Group B(femtosecond laser group)with 60 cases(120 eyes). Then the vision situation and corneal flap thickness indexes of two groups at different time after the treatment were compared.

RESULTS: The vision situation between the two groups at different time after the treatment all had no significant differences(all P>0.05), while the corneal flap thickness related indexes of Group B at different time after the treatment were all better than those of Group A(all P<0.05). The evaluation indexes of two groups after the treatment all had significant differences(all P<0.05).

CONCLUSION: The indexes of corneal flap made by femtosecond laser are better than those of microkeratome, and the influence of two methods for the vision is no obvious.
