Abstract

Introduction: Myopia is one of the most common types of refractive errors is that it is much more common in recent years .The aim of this study was to evaluate the results and Effectiveness of Refractive surgery photorefractive keratectomy (PRK tissue saving) to correct the myopia persons above 20 years suffering from refractive errors and corneal thickness less than refractive error and operated by Technolas  217 p device is on have been.

Methods: The study included 29 patients (15 female and 14 male) with an average of 58 eye myopia greater than -1.25 and patients with corneal opacity and lens, keratoconus and collagen, vascular diseases and ectasia removed examination with corrected visual acuity less than 20/25 and IOP higher than 21 mmHg were excluded from the study. Average myopia, astigmatism, pachymetry, keratometry and best corrected visual acuity was measured before surgery and six months after measured again.

Results: In this study, the mean age of the patients was 26.56 ±0.51 After surgery, myopia and astigmatism values are significantly decreased (p <.001) and average amount of myopia, astigmatism, pachymetry and keratometry respectively + 0.18 ± 0.06, -0.31 ± 0.03, 458.48 ± 38.9, 40.50 ± 0.23, respectively. All patients had best corrected visual acuity of 20/20 and also no statistically significant difference between male and female.

Conclusion: Photorefractive keratectomy surgery (PRK tissue saving) using Technolas  217 p for myopic patients with low corneal thickness of refractive error is very convenient. This study suggests that tissue-saving surgery for patients with low corneal thickness of refractive error, according to the results to be appropriate. This type of surgery can be offered to patients with similar conditions.
