Abstract Details


To evaluate epithelial thickness profile changes following myopic transepithelial surface ablation


SynsLaser Clinic, Oslo, Norway


Nineteen eyes of 19 patients were retrospectively recruited. Epithelial thickness mapping was obtained with a spectral-domain optical coherence tomography (Optovue Inc., Fremont, CA) preoperatively, as well as at 1 month and 3 months postoperatively. The central 2 mm area (Zc), the mean epithelial thickness between 2-5 mm zone (Z2-5), and between 5-6 mm zone (Z5-6) were analyzed.


Compared to preoperative values, the epithelial thickness remained the same at 1 month postoperatively (p>0.05). There was a thickening of 2.30±2.76, 3.82±2.14, and 4.74±2.21 µm respectively (p<0.05) at 3 months postoperatively.


The remodeling of the epithelial thickness profile changes after myopic transepithelial surface ablation happened between 1 and 3 months postoperatively. FINANCIAL INTEREST: NONE
