The Lamina Cribrosa (LC) Changes in the Eyes After Laser-Assisted in Situ Keratomileusis (LASIK)

The Lamina Cribrosa (LC) Morphologic Changes in the Eyes After Laser-Assisted in Situ Keratomileusis (LASIK)

The burden of LASIK surgery on optic nerve head (ONH) has been controversial. Until now, the change of retinal nerve fiber layer (RNFL) thickness was used as the indicator of the study. In the present study, the investigators intended to investigate whether the changes of the deep and superficial structures around ONH exist or not using EDI OCT.

Inclusion Criteria:

• the myopic patients who were supposed to undergo LASIK surgery in the Samsung Medical Center

Exclusion Criteria:

• Optic nerve head abnormalities at preoperative examination
• Previous ocular surgical history
