Abstract
Objective To investigate the effect of long-term wearing rigid contact lenses on the stability of tear film. Methods Eighty ( one hundred sixty eyes) patients were randomly divided into four groups:Group one,Long-term wearing RGP ( twenty patients,forty eyes);Group two,Long-term wearing orthokeratology lenses at night ( twenty-two patients,forty-four eyes);Group three,Long-term wearing soft contact lenses ( twenty patients,forty eyes); Normal control,low myopia patients without a history of wearing contact lenses (eighteen patients,thirty-six eyes). Patients’ vision,Schirmer I test, break-up time ( BUT) of tear film,conjunctival impression cytology ( CIC) ,and tear film fern experiments were performed before wearing lenses,wearing for one month,wearing for six month,wearing for one year,wearing for two years,respective-ly. Results The results of Schirmer I test and break-up time ( BUT) of tear film in each experimental group were re-duced as compared with normal control group. The difference was statistically significant (P<0. 05). After long-term wear-ing contact lenses,the conjunctival goblet cells was decreased in all experimental groups,and can not form a good ferning phenomenon. Conclusions Long-term wearing contact lenses can result in decreasing the stability of tear film and re-duce tear secretion.关键词
