For eyes with thin corneas that not suitable for LASIK, surface ablation is a very well proven alternative technique for laser vision correction. In surface laser treatment there is no need to create a permanent flap in the deeper corneal layer. Instead only the epithelial (skin) layer is removed, then the excimer laser ablation is applied underneath. Epi-LASIK, LASEK and PRK are 3 different methods of preparing the epithelium for surface laser treatment, Dr Lim is very experienced in performing all 3 procedures and will recommend the most appropriate procedure.
