Introduction The incidence of ectasia following refractive surgery is unclear. This review
sought to determine the worldwide rates of ectasia after photorefractive keratectomy (PRK) …

PURPOSE: To analyze the epidemiologic features of ectasia after excimer laser corneal
refractive surgery, to identify risk factors for its development, and to devise a screening …

Corneal surface laser ablation procedures for the correction of refractive error have enjoyed
a resurgence of interest, especially in patients with a possible increased risk of …

Purpose: To compare the postoperative biomechanical properties of the cornea after
photorefractive keratectomy (PRK) and after laser in situ keratomileusis (LASIK) in eyes with …

Surgical correction of refractive errors is becoming increasingly popular. In the 1990s, the
excimer laser revolutionized the field of corneal refractive surgery with PRK and LASIK, and …

PURPOSE: To study the role of the Pentacam (Oculus), Orbscan II (Bausch & Lomb), and
WaveScan (Visx) in evaluating topographic features identified as risk factors for ectasia after …

Purpose: To evaluate the outcome of treatment of mild to moderate keratoconus with
photorefractive keratectomy (PRK) and computed videokeratography for customized …

Purpose: To assess the safety and complication rate of sub-Bowman's keratomileusis (SBK)
in 3009 eyes. Methods: The flaps were created using the IntraLase femtosecond laser, and …

Background Corneal ectasia after photorefractive keratectomy (PRK) has only been
occasionally reported, and its incidence has not been assessed. Methods In a retrospective …

PURPOSE: To evaluate long-term outcomes after photorefractive keratectomy (PRK).
METHODS: A retrospective follow-up study of patients who received PRK at 5.0-to 6.5-mm …
