[Analysis of images in the prophylaxis and treatment of complications after kerato-refractive excimer laser surgeries].
A total of 236 eyes of patients with myopia and hypermetropia of different severity degrees after photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) were observed. The densitometry and planimetry analysis of corneal images, obtained through storing them in the computer memory, was used to evaluate postoperatively the corneal condition. Planimetry was used to forecast the time of epithelization and to assess the efficiency of drug therapy. The optic density was found to increase, after excimer-laser surgeries, in all patients and it depended on a type of refraction and its degree. The optic-density dynamics of corneal images also depended on a degree and type of refraction as well as on a type of drug therapy. Hence, densitometry and planimetry, as objective methods used to follow up the patients after keratorefractive excimer-laser surgeries, make it possible to diagnose early enough the presence of complications related with disorders in transparency and healing of the cornea.
