中小学生配戴角膜塑形镜安全性的临床观察

Clinical observation on the safety of primary and middle school students wearing orthokeratology

目的观察中小学生配戴角膜塑形镜的安全性。方法研究对象为2011年1月—2016年1月在我院验配角膜塑形镜的中小学生近视患者356例(712只眼),要求配戴者严格按照要求准时复诊,配戴时间为2年,分析其在配戴角膜塑形镜2年间角膜并发症的发生情况。结果 356例(712只眼)被观察者戴镜1个月、6个月、1年、2年发生角膜上皮损伤的眼数分别为162只眼(22.8%)、112只眼(15.7%)、71只眼(10.0%)、41只眼(5.8%)。戴镜后出现的角膜损伤多为Ⅱ级及Ⅱ级以下的角膜损伤,且在戴镜1个月多见,此后逐渐减少,其中在戴镜1个月出现的5例Ⅲ级的角膜上皮损伤的病例为镜片不慎掉地致镜片划伤,清洁不净所致,而且所有角膜损伤都经及时对症治疗痊愈。结论在规范使用及定期复查前提下,长期配戴角膜塑形镜有较高的安全性。

OBJECTIVE To observe the safety of primary and secondary school students wearing Ortho-K CL.METHODS The study subjects included356cases(712eyes)of myopia who were treated with orthokeratology in our hospital from January2011to January2016.The wearers were required to return to the clinic on time according to the requirements.The wearing duration was2years.The incidence of corneal complications during2years of wearing Ortho-K CL was analyzed.RESULTS Among the356cases(712eyes),these who suffered corneal epithelial damage1month,6months,1year,and2years after wearing Ortho-K CL were162eyes(22.8%),112eyes(15.7%),71eyes(10.0%)and41eyes(5.8%)respectively.They were mostly corneal injury of grade II and below,and were mostly happened one month after wearing glasses,and gradually decreased afterwards.The case of5cases of grade III corneal epithelial injury that occurred in one month of wearing glasses was caused by inappropriately cleaned lens after flopping to the ground accidentally.And all corneal injuries were cured by timely treatment.CONCLUSIONS The long-term wear of Ortho-K CL in a scientific and standard way would not lead to serious corneal complications,in other words,it was safe and reliable.
