Abstract:   (14410 Views)
PTK (Phototherapeutic Keratectomy) is the use of laser in corneal diseases. We can replace PTK for many other invasive procedures. The objective of this study is the assessment of this procedure in several cases in our practice. This investigation was a retrospective study, which was conducted based on comparison of 11 eyes with corneal eschars, induced by recurrent corneal erosions, pterygium surgery, corneal dystrophies and trachoma from 1994 to 1995. The mean age of cases was 32 years. The mean augmentation rate in hyperopia after one month was 1.5 diopter, and after one year it was 1 diopter. Although in two cases, the cylinder more than one diopter was induced, the mean rate for it was not increased significantly. One patient with recurrent erosion, who had not replied to any treatment, had no any complaint during one year follow up. During the follow up procedure, there were no any cases of vision loss among the patients.
