Background: The corneal epithelium plays a vital function in optics of eye. It influences tear film stability and maintains corneal function. topographic corneal epithelial thickness (CET) profile has been utilized in evaluation of corneal diseases such as corneal dystrophy and dryness .
Purpose: To map total corneal and epithelial layer thickness changes following cataract surgery using a spectral domain anterior segment optical coherence tomography AS-OCT.
Materials and Methods: This prospective observational case series was conducted on 60 patients who made phacoemulsification. All patients were imaged preoperatively and up to one month postoperatively with AS-OCT (Optvue-2800 Bayview Drive Fremont, CA 94538, USA). Corneal pachymetry and CET maps were analyzed and correlated with phacoemulsification time and break up time (BUT).
Results: 60 eyes of 60 patients, aged above 20 years ± 10.43sd were imaged Postoperatively, UCVA and BCVA improved after one week and one month postoperative (P
