Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To compare conventional v/s accelerated corneal cross linking by measuring contrast sensitivity using LogMAR values in Pelli Robson chart in presence of low to medium intensity glare of brightness acuity tester (BAT) and by comparing higher order aberrations (coma, spherical aberrations, trefoil) using Zernike polynomials in Pentacam topography Timepoint: 1 year | — |
Secondary
| Measure | Time frame |
|---|---|
| Cone location of Keratoconus using Pentacam topography and its effect on contrast sensitivity and HOA. Comparison of demarcation line depth between conventional v/s accelerated corneal cross linking using AS-OCT Timepoint: 1 year | — |
