Which vision correction procedure is right for me—LASIK, LASEK, or implantable lenses?

The best option depends on the results of a comprehensive eye examination. We assess your corneal thickness and shape, degree of nearsightedness and astigmatism, dry eye symptoms, pupil size, and retinal health before comparing procedures such as LASIK, LASEK, and implantable collamer lenses (ICLs). At First Samsung Eye Clinic, we recommend surgery only when the examination indicates that it is appropriate for your eyes.
