Abstract

The focusing system of eye is composed of several refracting structures which include cornea, aqueous humor, crystalline lens and vitreous humor. The overall refractive state of eye is determined by four components: Corneal power, anterior chamber depth, crystalline lens power and axial length. A state of emmetropia during development of eyeball is therefore the result of harmonious interplay of these components. Refractive error represents a mismatch between the eye’s focal length and its axial length. In this study, in simple myopic eyes with refractive error correction, we have done the biometry to know any correlation between biometric measures and degree of refractive error. Mean axial length in myopic was about 24.35±0.85 mm, which was more than the emmetropic eye and we found that there was a positive correlation between degree of myopia and axial length .In myopia we found deep anterior chamber and mean was 3.59 ± 0.28, p* = < 0.03 which indicates that there is positive correlation between degree of myopia and anterior chamber depth.

Keywords: Emmetropia, ammetropia, myopia, hypermetropia, astigmatism, keratometry,  a-scan, axial length, biometric measure, fundoscopy.
