Thickness and immunohistochemistry of LASIK flaps created by different femtosecond lasers in eye-bank corneas

Abstract

All 3 assessed femtosecond lasers provided predictable LASIK flap thickness. The mean stromal keratocyte apoptosis number was low in all groups.

Corneal Lenticule Creation Using a New Solid-State Femtosecond Laser Measured by Spectral Domain OCT in a Porcine Eye Model

“…The intended CT was the same for all eyes and showed no significant overall deviation in any group except for group 1. Similar results with excellent agreement of intended and measured cap thickness are shown by Reinstein et al 19 and Zhao et al 20 using the Visumax laser platform (Carl Zeiss Meditec) or for LASIK flaps with a deviation of less than 10 µm in eye bank corneas, 15 but some of those studies show a similar deviation but with a lower SD than in our data. A study by Colombo-Barboza was able to show a higher deviation from the intended measures for LASIK flaps but was significant at only 2 of 20 points measured, 21 and Parafita-Fernandez et al 22 had significantly thicker flaps than intended.…”
