Abstract

AIMS Aim of the study is to compare biometry and keratometry values in low and high myopia MATERIAL AND METHODS A sample of 50 patients were selected aged between (6 to 60) years in Silchar Medical college and Hospital and divided into two equal groups of low and high degree of myopia. Only myopic patients and those giving consent were included, patients those who had undergone ocular surgery were excluded. After proper ocular examination keratometry and A-scan biometry were measured from both the eyes of each patient. RESULTS The range of refraction did not differ very much between the two eyes. No significant difference was found between low and high degree of myopia in corneal curvature. Patients with high myopia were found to have longer axial length(P<0.0001) as compared to low myopic patients. CONCLUSION Axial length has a lot more effect on degree of myopia than corneal curvature
