LASEK may be safe in highly myopic eyes

PRAGUE — Using a specular microscope both preoperatively and postoperatively to study corneal endothelial cell density and other parameters, researchers found that LASEK is safe for correcting high myopia.
The poster study was presented at the winter meeting of the European Society of Cataract and Refractive Surgeons. Sung Kun Chung, MD, PhD, examined 44 eyes of 22 patients who underwent LASEK from January 2009 to December 2009 at St. Mary's Hospital in Seoul, Korea.
The Noncon Robo SP 8000 specular microscope (Konan Medical) was used to determine corneal endothelial cell density, coefficient of variation of the cell area, and percentage of hexagonal cells before surgery and 12 months after surgery.
Preoperative and postoperative corneal endothelial cell densities were 3131 ± 202 cells/mm2 and 3070 ± 179 cells/mm2, respectively; the difference was not statistically significant. The preop and postop coefficients of variation were 34.8 ± 5.0% and 32.5 ± 7.1%, respectively. The preop and postop percentages of hexagonal cells were 53.6 ± 12.0% and 53.8 ± 13.9%, respectively.
"Correlation between change in corneal endothelial cell and degree of myopia correction was not statistically significant," Dr. Chung said.
