Abstract Details


To evaluate the changes in relative pachymetry and asphericity after myopic excimer laser refractive surgery


Kudret Eye Hospital


he Intralase femtosecond laser (AMO Inc, Irvine, CA) was used to create the flap in all eyes that underwent LASIK. All eyes underwent LASIK with Zeiss MEL-80 excimer laser for the correction of myopia or myopic astigmatism. 32 eyes of 16 patients were included in the study. The minimum required follow-up was 6 months after LASIK. Each eye was evaluated by Scheimpflug camera imaging (Pentacam, Wetzlar, Germany). Relative pachymetry and asphericity values were analyzed and compared.


The mean relative pachymeter significantly decreased from -0.8 ± 0.2 (0.1 to -0.9) µm before surgery and -3.4 ±1.1 µm after surgery. The mean asphericity with q value was significantly increased from -0.17 ± 0.11 preoperatively to 0.38 ± 0.39 postoperatively . There was a significant correlation between the achived correction and decrease in relative pachymeter and also between inrease in asphericity.


The relative pachymeter decreases and the asphericity increases after myopic refractive excimer laser surgery. FINANCIAL DISCLOSURE?: No
