Hyperopia Correction Using an Erodible Mask Excimer Laser Delivery System Coupled to an Axicon: Preliminary Results

Abstract

These preliminary results indicate this approach is effective in reducing hyperopia, while its predictability has still to be proved in a larger treatment group with longer follow-up. A cautious approach to this technique is still advisable, especially for higher hyperopic corrections, in view of the large best corrected visual acuity loss seen in two eyes at six months.

Long-Term Efficacy of Photorefractive Keratectomy In Hyperopia Patients

“…The efficacy and reliability of PRK therapy in hypermetropic patients up to +5.00 D were documented in several studies [10][11][12][13][14][15][16][17]. It has been reported that in high hyperopia (˃5.00 D), PRK is a method that has less predictable results associated with higher regressions [18].…”
