Study of Accuracy of Corneal Flap Thickness using Femtosecond Laser Technology
George Adel Aziz;
Abstract
LASIK is the most popular surgery to correct the refractive errors nowadays, which is proved to be safe, effective and well predictable.
US pachymetry is considered the gold standard method for measuring CCT. Ultrasonic pachymetry while useful, it is less than ideal for intraoperative measurements during LASIK.
The Integrated optical pachymetry is a convenient and useful feature of the EX500 excimer laser.
It is important to produce a uniform flap with a narrow deviation from the intended thickness. In our study we aimed to measure the accuracy of Allegretto WaveLight® FS200 (Alcon Laboratories, Fort Worth, TX, USA) in creation of flap with different thicknesses measured by intraoperative optical pachymetry integrated with the EX500 Platform.
Sixty eyes of 30 myopic patients were included in our study , the patients were operated in Al Watani Eye hospital by 2 different surgeons from June 2017 till December 2017.
The patients were distributed randomly on the three studied groups. Group A with flap thickness 100um , Group B with flap thickness 110um and Group C with flap thickness 120um.
