摘要
目的探讨硬性透气性角膜接触镜（RGPCL）矫正成人超高度近视的临床效果。方法回顾性病例研究。选择在湖南省人民医院眼视光医学中心验配RGPCL的24例（43眼）成人超高度近视患者，根据其屈光度、角膜地形图、角膜曲率和配适情况选择合适的RGPCL镜片。戴镜后7d、1个月、3个月、6个月观察配戴RGPCL时的矫正视力、不良反应和并发症。采用卡方检验和非参数检验对数据进行分析。结果框架眼镜最佳矫正视力平均为4．62-0．15，≥4．9者1眼，占2％：配戴RGPCL后最佳矫正视力平均为4．77-0．16，94．9者16眼，占37％，差异有统计学意义（x^2=16．496，P〈0．05）；与戴镜后7d相比，戴镜后1个月舒适度指标总积分及异物感、视力波动、痒、刺痛、干涩、充血症状的积分均下降，差异均有统计学意义（x^2=63．948、63．823、39．168、6．459、57．733、44．164、39．420，P均〈0．05）。与戴镜后1个月相比，戴镜后3个月总积分、异物感、视力波动、充血症状积分持续下降，差异均有统计学意义（x^2=35．536、22．484、11．537、16．229，P均〈0．05）；痒、刺痛、干涩症状积分与戴镜后1个月差异无统计学意义（x^2=0．000、1．184、1．398，P均〉0．05）。镜片配适中心定位好，活动度良好，未见角结膜严重并发症。结论RGPCL矫正成人超高度近视可明显提高其矫正视力，能有效提高患者的视觉质量和生活质量。
Objective To investigate the effect of using rigid gas-permeable contact lens （RGPCL） for severe myopia. Methods This was a retrospective case study. Twenty-four adults （43 eyes） with severe myopia were fitted with RGPCLs based on their subjective refractions, corneal topography, corneal curvatures and diagnostic fitting. The corrected visual acuity, adverse reactions and complications were observed 7 days, 1 month, 3 months and 6 months after the start of wearing the lenses. Data were analyzed using a chi-square test and non-parameter test. Results Corrected visual acuity with RGPCLs was 4.77±0.16, which was better than that with spectacles （4.62±0.15）. The result was statistically significant （X2=16.496, P〈0.05）. The pan score, foreign body sensation scores, unstable vision, itching, pain, dryness, and hyperemia changed significantly from 7 days to 1 month after RGPCL wear （X2=63.948, 63.823, 39.168, 6.459, 57.733, 44.164, 39.420, P〈0.05）. Compared with 1 month after RGPCL wear, the pan score, foreign body sensation scores, unstable vision, and hyperemia continued to decrease after 3 months （XZ=35.536, 22.484, 11.537, 16.229, P〈0.05）, while no statistical difference was found for itching, pain, or dryness （X^2=0.000, 1.184, 1.398, P〈05）. In general, the patients felt comfortable and there were no serious complications. Conclusion RGPCLs are a safe and effective approach to improve visual acuity for severe myopia in adults. RGPCLs are superior to spectacles for providing optical corrections and corrected visual acuity.
