Refractive surgeries are designed to alter the corneal curvature or change the lens power to allow light rays to focus on or near the retina, thus improving vision. Currently, the most commonly performed refractive surgery is called LASIK, for correction of myopia, hyperopia and astigmatism. The Hong Kong Sanatorium & Hospital is the first hospital in Hong Kong to employ LASIK surgery techniques.

Refractive Surgeries on Cornea:

• Radial Keratotomy (RK)
• Laser-assisted In-situ Keratomileusis (LASIK)
• Photo Refractive Keratectomy (PRK)
• Laser Sub-Epithelial Keratomileusis (LASEK)
• Epithelial Laser-assisted In-situ Keratomileusis (Epi-LASIK)
• Implantation of Intra-Corneal Ring (ICR)
• Conductive Keratoplasty (CK)
