Regression after Laser Correction of Hyperopia

D. Mitova, T. MItov, M. Litev

Abstract

Purpose: to analyse causative factors for regress in hyperopic laser vision correction. Materials and methods: Metaanalysis of the literature and retrospective analysis of 20 consecutive cases of recorrection at the St. Petka Eye Clinic Varna in the last year. Correlation with pre- and post- operative Kmax, pachimetry (center/periphery), nuclear sclerosis and dysfunctional lens syndrome, total ablation zone, optical zone, cycloplegic refraction, target refraction, age of the patient was done. Re-correction was done with re-lift in 18 of the patients and with re-cut in two of them. Results: Small optical and total ablation zone showed positive correlation with hyperopic regress, while flap diameter correlates as far it is linked to the total ablation zone. Positive correlation was found in thin corneas and in patients over 50 years of age. Discussion: Based on the analysis of the results, recommendations for operative protocol was elaborated in order to minimize the risk for regression post hyperopic LASIK.
