Eligibility

Inclusion criteria

Inclusion criteria: • Worsening of uncorrected distance visual acuity (UDVA) or best corrected distance visual acuity (BDVA) of > 0.50 Snellen lines • Increase of manifest spherical or cylindrical refractive error of > 0.50 Diopter • Increase in steepest keratometry value (on Sim K or Manual) by >=1D • Increase in mean K reading >= 1â??D • Reduction of the thinnest point at corneal optical coherence tomography (OCT) pachymetry >=10â??μm

Exclusion criteria

Exclusion criteria: • Thin corneas ( Corneal pachymetry at thinnest point • Prior herpetic infection because it may result in viral reactivation • Concurrent infection • Severe corneal scarring or opacification • History of poor epithelial wound healing • Severe ocular surface disease ( moderate to severe dry eyes Schirmer test I • Autoimmune disorders • Pregnant and nursing mother • Previous intraocular and corneal surgery • Glaucoma or IOP higher than 24mmHg
