佩戴角膜塑形镜后出现视力波动的原因分析

Cause analysis of vision fluctuation after wearing orthokeratology lens

目的探讨佩戴角膜塑形镜后出现视力波动的原因,并对相关危险因素进行统计分析,以实施针对性的干预措施。方法选取2017年5月至2019年5月于本院就诊的因近视而佩戴夜戴型角膜塑形镜的300例患者,通过查阅病历、跟踪随访等方式找出配戴角膜塑形镜后出现视力波动的原因,对相关危险因素进行单因素和多因素Logistic回归分析。结果300例佩戴角膜塑形镜患者中出现视力波动的患者41例,发生率为13.7%,患者角膜上皮损伤、镜片偏位、眼轴增长、戴镜时间≥6 h、镜片超期及镜片配适异常及调节异常是发生视力波动的独立危险因素。结论初期应严格选择合适的角膜塑形镜及佩戴后应严格定期复查、及时更换镜片以免影响长期的佩戴效果。

Objective To investigate the causes of vision fluctuations after wearing orthokeratology lenses,and provide targeted intervention measures.Methods 300 children who were treated at the our hospital from May 2017 to May 2019 were selected who were wearing night-wearing orthokeratology due to myopia,and the causes of visual acuity fluctuations after wearing orthokeratology lenses were found out by reviewing medical records and follow-up,and univariate and multivariate Logistic regression analysis was performed on the relevant risk factors.Results Among the 300 orthokeratology patients,41 cases had vision fluctuations,the incidence rate was 13.7%.Corneal epithelial damage,lens deviation,eye axis lengthening,lens wearing time≥6 h,lens expiration,and abnormal lens fit and adjustment were independent risk factors for vision fluctuations.Conclusion Strictly select the appropriate one at the initial stage ortho keratoplasty lenses and after wearing should be reviewed regularly and the lenses should be replaced in time to avoid affecting the long-term wearing effect.
