OBJECTIVE: Photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK)
outcomes were compared at 1, 3, 6, and 12 months after surgery. DESIGN: Retrospective …

ABSTRACT BACKGROUND: A change of corneal topography and haze after excimer laser
photorefractive keratectomy (PRK) can reduce contrast sensitivity and cause glare. Both …

Purpose To compare corneal light scattering after laser in situ keratomileusis and
photorefractive keratectomy in rabbit eyes. Methods For laser in situ keratomileusis, a 5 …

Purpose: To determine whether contrast sensitivity measurement, a more sensitive test of
visual function than visual acuity, better characterizes visual outcomes after laser in situ …

ABSTRACT PURPOSE: To describe variation in surgical and patient management and to
assess their effect on 12-month outcomes of photorefractive keratectomy (PRK). METHODS …

Purpose To evaluate the optical quality after laser in situ keratomileusis (LASIK) or serial
photorefractive keratectomy (PRK) using a double-pass system and to follow the recovery of …

PURPOSE: To report the outcomes of photorefractive keratectomy (PRK) enhancement after
LASIK for patients diagnosed as having hyperopic and myopic refractive errors. METHODS …

I. 100 myopes (-0.25-(8.75) D) divided into 3 groups (I:<-3.0 D, II:-3.0-(-5.75) D, III:-6.0-(-8.75)
D) were examined before and 1, 3, 6 months after photorefractive keratectomy (PRK). As a …

Purpose To evaluate the effects of photorefractive keratectomy (PRK) on the stereopsis of
myopic and hyperopic patients. Setting Farabi Eye Hospital, Tehran, Iran. Design …

ABSTRACT PURPOSE: To study the utility of measurements of contrast sensitivity at
different spatial frequencies as an index of visual recovery following refractive surgery …
