长期配戴角膜塑形镜对角膜内皮细胞的影响观察

目的：评价近视眼患者长期配戴角膜塑形镜后不同时期角膜内皮细胞密度和形态的情况。方法：用非接触型角膜内皮显微镜对22例（44眼）配戴角膜塑形镜者，在戴镜前、戴镜后1年及2年作角膜内皮细胞照相观察。结果：戴镜前、戴镜后1年及2年角膜内皮细胞密度分别为（3228±168）个／mm2、（3192±172）个／mm2及（3178...

Observation of the Influence to corneal endothelial cell from long- term wearing orthokeratology Lenses

Objective： To evaluate the comeal endothelial cell density and morphological changes by periods after longterm wearing Orthokeratology Lenses. Method：22 patients （44 eyes） wore orthokeratology lenses were graphically recorded and observed by Non - contact Specular Microscope at the time of before wear, 1 year after wear and 2 years after wear. Results：The coroeal endotheliaf cell density at each time point were （3228 ± 168） cells/mm2 （before wear）, （ 3192 ±172 ） cells/mm2 （ 1 year after wear ） and （ 3178 ± 181 ） cells / mm2 （ 2 years after wear } （ P 〉 0. 05 ）. Conclusion： For slight and medium myopia patients, using orthokeratology lenses which made of Highly Oxygen - permeable material for comea moulding have no influence to corneal endothelial cell density and morphology, o rthokeratology lenses wearing is a safe way for myopia correction.
