Brief Summary
|
1.Medical college students of KMCH IHSR will be undertaken as subjects for the prospective cross-sectional study and they will be screened for any refractive errors in their eyes. 2.Visual acuity testing will be done for patients using Snellen’s Chart for distant vision and Jaeger’s Chart for near vision, following detailed examination of eye to rule out causes of visual impairment other than refractive errors. 3. A pre-framed questionnaire will be made to answer by the students to identify any risk factors associated and feedback will be obtained. 4.Students who have difficulty reading 6/6 and N/6 will be evaluated under an auto-refractometer, and after cycloplegic instillation they will be examined under a streak retinoscope, followed by slit lamp examination and indirect ophthalmoscope examination to rule out other defects in the anterior and posterior segment, respectively. 5.Following appropriate protocol, ensuring quality control, and assessing through standard calibrated instruments, refractive error findings will be recorded and categorized. Data will be collected and recorded with the help of various statistical tools. 6.Through maintaining confidentiality and following ethical principles, the data will be collected from the patient population and made to analyze, categorize according to varying refractive errors. 7.Refractive errors like myopia, hypermetropia, and astigmatism will be segregated in groups. A proportion of these uncorrected refractive errors among the medical college students will be reported. |
