Abstract Details


To evaluate biomechanical and confocal microscopy (CM) changes in myopia and correlate with corneal thickness


Dr Rajendra Prasad Centre for Ophthalmic Sciences, AIIMS, New Delhi, India


Prospective evaluation of 204 eyes (102 patients) with myopia ≥ 0.5 D planned for laser refractive surgery. Eyes were divided on basis of thinnest pachymetry (CT) -group I: CT ≤500 μm, group II: CT >500 μm. Corneal hysteresis (CH), corneal resistance factor (CRF) and CM findings were evaluated.


Mean age was 22.78 ± 2.43 years. 57 eyes had CT ≤500 μm and 147 eyes had CT >500 μm. Group I had significantly lesser midstromal keratocyte density (SKD) (p=0.01), CH (p=0.01) and CRF (p=0.004) than group II. Corneal biomechanics (CH and CRF) significantly correlated with CT (r=0.45 & 0.36, p<0.001) and anterior SKD (r=0.4, p<0.001). There was poor correlation between magnitude of refractive error and CT


Thinner corneas (≤500 μm) have suboptimal corneal biomechanics and keratocyte density as compared to thicker corneas
