TLDR
Topography patterns after PRK are identifiable, time dependent, and may affect clinical outcomes, and the optical zone contour is defined quantitatively for both laser techniques and optical results in the future.About:

Photorefractive keratectomy versus laser in situ keratomileusis for moderate to high myopia: A randomized prospective study
Peter S. Hersh,Stephen F. Brint,Robert K. Maloney,Daniel S. Durrie,Michael Gordon,Marc Michelson,Vance Thompson,Ralph B Berkeley,Oliver D. Schein,Roger F. Steinert +9 more
TL;DR: There is a greater tendency toward undercorrection in LASIK eyes using the specific laser and nomogram in this study, but the scatter in achieved versus attempted correction is similar, suggesting little difference in the accuracy of the two procedures.

Effect of pupillary dilation on corneal optical aberrations after Photorefractive keratectomy
Carlos E. Martinez,Raymond A. Applegate,Stephen D. Klyce,Marguerite B. McDonald,Jan P. Medina,Howard C. Howland +5 more
TL;DR: The analysis shows that the increase in aberrations measured for simulated night vision (7-mm pupil) supports the use of large treatment zones to reduce visual disturbances such as glare and halos and the correlation of these data with visual performance in clinical trials provide the basis for understanding patient complaints.
Journal ArticleDOI
Night Vision Disturbances After Corneal Refractive Surgery
TL;DR: There are no gold-standard clinical tests available to measure glare disability, contrast sensitivity, or image degradations after refractive surgery, so standardization is essential for objective measurement and follow-up to further understand the effects of these surgeries on the optical system and thus, hopefully, allow for modification of techniques to decrease or eliminate post-refractive vision disturbances.

Laser in situ keratomileusis for moderate and high myopia and myopic astigmatism
TL;DR: The LASIK method showed stability of manifest refraction and adequate uncorrected central visual acuity in a large percentage of patients with myopia up to -15.00 D and satisfactory patient satisfaction of the spherical (toric) groups at 12 months.

Gold,Bernard A. Milstein +24 more
TL;DR: Photorefractive keratectomy appears effective for myopic corrections of -1.50 to -6.00 D, although some patients require between 6 months and 1 year to attain their best postoperative uncorrected visual acuity and some may require from 1 to 2 years for stabilization of refraction.

Photorefractive keratectomy: A technique for laser refractive surgery
TL;DR: Conditions for one such procedure, photorefractive keratectomy, the direct reshaping of the cornea's central optical zone using tissue ablation with far ultraviolet radiation is described and a method of achieving better beam uniformity using beam integration by rotation is demonstrated.

Centering corneal surgical procedures.
Hiroshi Uozato,David L. Guyton +1 more
TL;DR: Proper centering requires the patient to fixate on a point that is coaxial with the surgeon's sighting eye, and the cornea is marked at the point in line with the center of the patient's entrance pupil, ignoring the corneal light reflex.

Computer-assisted corneal topography. High-resolution graphic presentation and analysis of keratoscopy.
TL;DR: A computer-based analysis system was developed to assist in the clinical interpretation of keratoscope images, and deviations from sphericity are displayed in graphic form to aid in the recognition of abnormalities, and surface powers are presented in tabular form.

Classification of Normal Corneal Topography Based on Computer-Assisted Videokeratography
TL;DR: There was a statistically significant difference among patterns for ker atometric astigmatism, but not for spherical equivalent refraction, mean keratometric power, or age of subject.
