Purpose:
Laser assisted subepithelial keratomileusis(LASEK), along with Laser assisted in situ keratomileusis(LASIK) and Photorefractive keratectomy(PRK) is a widely used technique for correcting high myopia. The safety of LASIK and PRK has been reported by many researchers, but that of LASEK is yet to be researched. In order to investigate its safety, we used specular microscope before and after the LASEK procedure
Setting:
: St. Mary’s Hospital, Seoul, Korea
Methods:
22 patients(44 eyes) who underwent LASEK between January 2009 and December 2009 were included in this study. Parameters included corneal endothelial cell density(CD), coefficient of variation of the cell area(CV), and percentage of hexagonal cells(6A) which were all obtained by a specular microscope(Noncon ROBO sp 8000, Konan, Japan) before and 12months after the LASEK.
Results:
Preoperative CD and postoperative CD were 3131±202 cells/mm2 and 3070±179 cells/mm2, respectively, which was not statistically significant. Preoperative CV and postoperative CV were 34.8±5.0% and 32.5±7.1%, respectively. Preoperative 6A and postoperative 6A were 53.6±12.0% and 53.8±13.9%, respectively. Furthermore, correlation between change in corneal endothelial cell and degree of myopia correction was not statistically significant.
Conclusions:
The results showed that LASEK is safe for correction of myopia.
