Pdt assisted vision correction and scar prevention

摘要: A method and formulation are disclosed for improving the results of corneal refractive surgery, generally reducing post-operative scarring arising from other traumas. In vision examples, after completion a procedure, including Photorefractive Keratotomy (PRK) or Laser-In-Situ Keratomileusis (LASIK), photosensitizer precursor is applied to treatment site. After allowing sufficient time photosensitizers accumulate among proliferating cells that occur as result ablation, radiation appropriate activate administered The thus activated destroy only those cells. this way, tissue eliminated cornea maintains shape created during surgery. As result, instances regression need follow-up treatments, minimized. This also useful preventing post-surgical can lead problems such haze. Likewise formulations, presented here, suitable scarring, trauma cased in general. For scars, topically attach cells,
