Actual (reported)Hyperopia is one of the commonest refractive errors encountered in ophthalmology practice. Laser in situ keratomileusis (LASIK) has been widely used to correct hyperopia especially with the advent of femtosecond laser technology allowing larger flap creation suitable for peripheral hyperopic ablations with resultant predictable, effective, and safe refractive outcomes. However, the encountered LASIK flap complications encouraged many surgeons to assess efficiency and safety of surface ablation techniques such as photorefractive keratectomy (PRK) to correct hyperopia.

Patients with moderate hyperopia or hyperopic astigmatism were planned to undergo transepithelial PRK using the new single-step StreamLight PRK Technology.
Single-step transepithelial Photorefractive keratectomy (PRK) is a corneal refractive surgical procedure utilized to correct myopia, hyperopia and astigmatism where excimer laser is used in a single step to remove the corneal epithelium followed by stromal laser ablation to correct the patient's refractive error.
