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,≥4.9者16眼,占37％,差异有统计学意义(x2=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(x2=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(x2=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(x2=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 (x2=35.536,22.484,11.537,16.229,P＜0.05),while no statistical difference was found for itching,pain,or dryness (x2=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.
