Purpose:
The study aimed to evaluate in vivo the corneal structure after refractive surgery and monitor morphologic and morphometric changes in the post-operative period.
Material And Methods:
The study included 35 eyes (25 patients) who underwent LASIK correction of myopia. The structure of the cornea was evaluated in vivo using a scanning slit confocal microscope. Each cornea was examined before, 2, 4 and 8 weeks after procedure. The keratocyte density was evaluated morphometrically in the anterior and posterior corneal stroma.
Results:
Before surgery the keratocyte density in the anterior stroma ranged from 900 to 1200/mm2, while in the posterior stroma it ranged from 600 to 950/mm2. 8 weeks after LASIK the keratocyte density in anterior stroma ranged from 695 to 1048/mm2 and in posterior stroma from 565 to 935/mm2.
Conclusions:
After LASIK the keratocyte density decreases in anterior stroma while in posterior stoma it is constant.
