Cross sectional study This study was carried out at the out-patient department of Ophthalmology Dow University of Health Science [OJHA campus] , Karachi Pakistan from January 2011 to June 2011. Total of 691 patients were included in the study. The testing and examination protocol included visual acuity measurement using Snellen and E chart after auto refraction, cycloplegic retinoscopy in children and examination of anterior segment and fundus in all patients. Mean age was 42.11 +/- 17.35 years. Males were 323 and females were 368 in number. The most frequent refractive error was Myopia which was found in 153 [22.1%] patients and the second frequent refractive error was Myopic Astigmatism at a frequency of 148 [21.4%] ; p value was 0.037. Thus Myopia and myopic astigmatism were the most frequent refractive error in age group ranging from 05-75 years. In our study we found Myopia to be the most common refractive error [n=153 22.1%] followed by Myopic Astigmatism [n=148 21.4%] . Myopia and Myopic Astigmatism were seen in males more than females while hypermetropia, hypermetropic astigmatism and mixed astigmatism were seen in more in females as compared to males
