Photorefractive keratectomy (PRK) in the military aviator: an aeromedical perspective.

Aviation, space, and environmental medicine, 1996
Refractive surgery to visually rehabilitate refractive errors of the eye continues to evolve at a significant pace and is here to stay. The surgical manipulation of the cornea by carefully planned incisions, as in radial keratotomy, represented the first procedure to evolve for the correction of ametropia and is an area of continued active development ...

Corneal Epithelial Wound Healing After Excimer Laser Photorefractive and Photoastigmatic Keratectomy (PRK and PARK)

Cornea, 1999
This study compared the duration of corneal reepithelialization between photorefractive (PRK) and photoastigmatic (PARK) keratectomy and evaluated the possible correlation of the epithelial healing rate with clinical parameters as well as the refractive outcome.The duration until complete reepithelialization was examined in 33 eyes of 33 patients (14 ...

[Photorefractive keratectomy (PRK). The limits of our knowledge].

Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 1995
The confines of our knowledge with respect to excimer laser photorefractive keratectomy are particularly manifest in two areas: the effects of the excimer on the corneal tissue, especially in the course of the wound healing process; and the optical aberrations caused by the laser treatment through structural alterations in a previously clear cornea ...

Near Point of Accommodation and Convergence after Photorefractive Keratectomy (PRK) for Myopia.

Binocular vision & strabology quarterly, Simms-Romano's, 2016
Near point of convergence (NPC) and near point of accommodation (NPA) were evaluated before and after photorefractive keratectomy (PRK) in normal myopic eyes.In this prospective cross sectional study, NPC and NPA were measured in 120 myopic eyes (60 patients) before and 3 months after PRK.
