目的：比较有晶状体后房型人工晶状体植入术(PPCIOL)与飞秒激光LASIK术治疗高度近视对术后视觉质量的影响。

方法：回顾性分析研究。随机选择我院2015-06/2017-06收治的83例166眼高度近视患者，按治疗方式不同分为两组，A组予以PPCIOL治疗，B组予以飞秒激光LASIK术治疗。比较两组患者有效性指数、安全性指数、视力和屈光度、高阶像差变化、对比敏感度值和并发症发生情况。

结果：两组患者有效性指数比较差异无统计学意义(P>0.05)，A组安全性指数高于B组(P<0.05)。术后两组患者UCVA和BCVA视力≥1.0眼数均增加，屈光度均下降(P>0.05)。与术前比较， 术后A组明视、暗视无眩光和有眩光对比敏感度值差异无统计学意义(P>0.05)； 与A组比较， 术后B组明视、暗视无眩光和有眩光对比敏感度值均下降，组间和组内比较差异有统计学意义(P<0.05)。两组患者并发症发生情况比较无差异(P>0.05)。

结论：PPCIOL和飞秒激光LASIK术均可有效矫正高度近视患者视力，但PPCIOL对高阶像差和对比敏感度的影响较小，在术后视觉质量方面更有优势。

METHODS: Randomly selected 83 patients with 168 eyes with high myopia from 2015-06/2017-06 in our hospital, they were divided into two groups according to the treatment. Group A was treated with PPCIOL, and group B was treated with femtosecond laser LASIK. The efficacy index, safety index, visual acuity and diopter, high-order aberration changes, contrast sensitivity values, and complications in both group were compared.

RESULTS: There was no significant difference in the efficacy index between the two groups(P>0.05), and the safety index of group A was higher than that of group B(P<0.05). The number of patients with UCVA and BCVA greater ≥1.0 after surgery in both groups were increased, while the diopter decreased, and the difference between the two groups was not statistically significant(P>0.05). Compared with preoperative, there was no significant difference in the contrast sensitivity between the visual acuity, scotopic glare and glare in group A(P>0.05). Compared with group A, the visual sensitivity, glare-free glare and glare contrast sensitivity values of group B decreased, and the differences between groups and groups were statistically significant(P<0.05). There was no significant difference in the incidence of complications between the two groups(P>0.05).

CONCLUSION: PPCIOL and femtosecond laser LASIK can effectively correct the vision of patients with high myopia, but PPCIOL has less influence on high-order aberrations and contrast sensitivity, and has more advantages in postoperative visual quality.
