Abstract
Purpose: To investigate the frequency and structure of a subepithelial fibroplasia of a cornea after photorefractive keratectomy concerning myopia correction.
Methods: 170 patients (337 eyes) with the following refraction anomalies: stationary myopia from 1.5 to 13.0 D with astigmatism from 0.75 to 4.25 D. Frequency of survey in the postoperative period — in 1, 3, 6, 12 months. To all patients Dexamethasone instillation according to the decreasing scheme was carried out. Existence of biomicroscopic signs of any degrees of subepithelial fibroplasias of a cornea, existence and extent of loss of uncorrected visual acuity in comparison with initial, regress of refractive effect of operation were taped. Subjective estimation of quality of vision was made by patients in 1 year after operations.
Results: Subepithelial fibroplasias with intensity 1.0‑2.5 points stopped in whole or in part after additional treatment, were surveyed as clinically significant and made 4,75 % (16 eyes, 9 patients). Terms of their emergence: from 1 to 10 months after operation. At 3 patients (6 eyes) intensity of fibroplasias made 2.0‑2.5 points before treatment and 1.0‑2.5 points after it. To the observation extremity 7 patients from this group had visual complaints, a discomfort in an eye. Indicators of Subjective estimation of quality of vision in patients with clinically significant fibroplasias of a cornea varied from 5 to 2.9 points.
Conclusion: Frequency of clinically significant fibroplasias after photorefractive keratectomy made 4.75 %. After treatment their
intensity made 1.5‑2.5 points only in 4 eyes (2 patients).
