Abstract:AIM:To study the wearing crowd distribution and the compliance of lens wearing·METHODS: Retrospective case investigated research.Clinical data of 454 patients with optometry of rigid gas permeable contact lens(RGPCL) from February,2008 to December,2008 were investigated.Patients with RGPCL were reviewed to study age,gender,refractive state,wearing purpose as well as the compliance of lens wearing for the first time·RESULTS: Of the 454 RGPCL wearers,the proportion of male to female was 1∶2.66;Respondents,according to age,were divided into 10-12 years group with 45 casses(9.9%),13-18 years group 243 cases(53.5%)and >18 years group 166 cases(36.6%),in which 13-18 years had the highest proportion;57.5% of patients wearing RGPCL aimed to control myopia development,51.5% of patients for correcting high myopia or hyperopia,41.2% of patients for wearing convenience;The average review time was less than 3 months in 68 cases(15.0%),3-6 months(including 6 months)in 98 cases(21.6%),7-9 months in 26 cases(5.7%),more than 9 months in 50 cases(11.0%),never to check in 212 cases(46.7%)·CONCLUSION: 13-18 age is the main stage of wearing RGP lens,to control the progress of myopia is the main purpose of the wearers.The compliance of wearing RGPCL is effected by reasons of uncomfortable wear,tedious wearing process.Wearers of all ages have no significant difference in compliance,education needs to be further strengthened.Women patients wearing propotion is more than men patients,compliance is also significantly higher than male.The survey also show that education of patients have no significant influence on fitting rate and the compliance.
