title: [Changes in corneal topography after photorefractive keratectomy in myopia and their elimination].
abstract: Topographic disorders in the cornea, regression of the refraction effect, and subepithelial corneal opacities are characteristic complications of photorefraction keratectomy. Disorders in corneal topography are early haze, asymmetrical haze, and optic zone decentration. Disorders in topography lead to decrease in visual acuity, numerous optic effects (monocular doubling, aureola, blurred image, etc.). Methods for these complications control by means of transepithelial ablation, which is carried out with due consideration for the data of topographic examinations under pseudofluorescence control, normalizes corneal topography in the majority of cases, notably increases visual acuity, decreases doubling, etc. No side effects were observed after transepithelial phototherapeutic keratectomy for a period of up to 12 months.
