Our colleagues from around the world, agree on when not to do LASIK, like when the cornea is very steep or very flat. In the early days, PRK was very painful and vision was not good. Khanna performs the safest and most technologically advanced methods of refractive laser surgery, including the ultra precise Wave Print, 3D Active Trak and Variable Spot Scanning used to correct near-sightedness, far-sightedness and astigmatisms. He does surgery on patients from all over the United States. With dvanced surface ablation there is minimal pain and most patients resume work in 3-4 days. In those cases we feel strongly that advanced surface ablation or (PRK) would be the preferred procedure. This procedure involves sculpting the cornea at the surface.V. Chilled BSS is used to cool the cornea.A bandage soft contact lens, is placed afterwards to maintain comfort in the eye. Khanna is an Internationally recognized top LASIK and refractive vision care specialist. The underlying Bowman's membrane (the micro-thin second tissue layer of the cornea that lies just below the epithelium, or outer layer) is exposed. This is done by removing the epithelium, (the film-like protective outer layer of the cornea) using a special instrument called Amoils epithelial scrubber. Although recovery is usually longer than with LASIK, patients are very happy with their vision. Oral vitamin C along with steroidal and non-steroidal, anti-inflammatory drops are prescribed. Mitomycin C may be applied if indicated. His offices are located at Santa Monica and Westlake Village in Southern California.This information has been shared at seminars, meetings and now, even on webmail.In patients with corneal thickness below a certain minimum, performing LASIK would be unwise, because the "foundation" may not go back to its original stability. Dr.Laser pulses with variable spot size and variable repetition rate are applied in a blended large zone. Patients are asked to wear dark U.
