Summary
In the last 30 years the rise of refractive surgery and the hope of permanently correcting ametropia, especially myopia, has developed and progressed greatly[1,2,3]. Rigid gas permeable (RGP) lenses are the most commonly prescribed contact lens to post-refractive surgery patients due to their high oxygen transmissibility, tear exchange properties, exceptional movement and excellent optical properties[24]. Their highest success rate is when fitted to corneas with a curvature no less than 38 D.25, 26. To fit a patient with a rigid gas permeable contact lens post-refractive surgery, it is best to wait until all corneal edema has subsided This usually occurs after a period of 3-6 months[6, 24, 29, 30]. Due to the central pooling between the posterior lens surface and the anterior surface of the cornea a very high plus powered tear lens is formed resulting in a very high minus powered over refraction[5, 24]
