Background and Objectives: Eyes are the most important organ of human body which is responsible for the vision. enable individual to see, the ability to perceive image which provides information about vision, and enables many photo response functions that are not dependent on vision. The aim of this study is to compare the effect of central corneal thickness on myopic, hyperopic, astigmatic and emmetropes of different age groups. The study involves 60 subjects i.e myopia more than (<-8.0 D), hyperopia more than (< +4.0 D), and astigmatism more than (<-3 D).
METHODOLOGY: TThe central corneal thickness was measured with pachymeter and keratometer than all the
data entered in Microsoft excel for statistical analysis. Study design will be descriptive cross sectional study design and use proposive sampling technique. Age group will be taken between 15 to 30 years. Exclusion criteria are keratoconus,mentally retared patients, nystagmus, corneal wrapage and wrinkling. Duration of study includes Oct 2020 to May 2021.This study is conducted in Madinah teaching Hospital and Allied Hospital FSD. RESULTS: There was no significant difference between the myopic and hyperopic and emmetropic eyes of different age groups.
CONCLUSION: We assume that there is no correlation was found of central corneal thickness on different types of refractive error.
