  1.

  2. Purpose • To compare the visual and refractive results and in vivo confocal microscopy findings of patients treated with PRK and LASEK in their fellow eyes.

  3. Methods • The charts of first consecutive 212 patients that underwent LASEK were reviewed retrospectively. • In patients where alcohol assisted epithelial removal failed to create a regular epithelial flap, the procedure was converted to PRK by scraping the residual epithelium using a beaver blade.

  4. Methods • The patients operated with PRK in their one eye and Lasek in their fellow eye are included in the study. • All procedures were carried out using Nidek EC CXII excimer laser system. • The corneal morphology were evaluated with in vivo confocal microscopy (Nidek Confoscan 3) at the last visit of the patients.

  5. Results • 34 eyes of 17 patients were included in our study. • 5 patients were male and 12 patients were female. • Mean patient age was 30.4±8.1 years. • Mean follow-up time was 15.9±11 months. • Confocal microscopy were performed on 9 patients (18 eyes) 22.7±11 months after the operation.

  6. Results Mean Spheric equivalent

  7. Results Mean Snellen Visual Acuity * Last visit:16 months

  8. Results Invivo Confocal Microscopy

  9. Conclusion • LASEK performed eyes has higher UCVA at postoperative 3rd month • Visual and refractive results in both techniques is similar at postoperative 9thand 16thmonth. • In vivo confocal microscopy did not demonstrate any morphological differences in eyes treated with both techniques. • Failure in epithelial flap preperation in Lasek surgery does not alter refractive outcome and does not make any effect on corneal morphology.
