• Photorefractive keratectomy for low-to-moderate myopia and astigmatism with a small-beam, tracker-directed excimer laser [1].
• We describe three patients with high myopia, 13.0 to 20.0 diopters (D), who had typical myopic macular hemorrhages 1 to 6 months after photorefractive keratectomy (PRK) [2].
• PURPOSE: To evaluate photorefractive keratectomy (PRK) in pediatric patients who fail traditional methods of treatment for myopic anisometropic amblyopia and high myopia [3].
• PURPOSE: To evaluate the ablation centration after photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) for high myopia and to assess the association between decentration and best corrected visual acuity (BCVA), glare, monocular diplopia, and halo phenomenon [4].
• We analyzed cases of subclinical keratoconus, central island, photorefractive keratectomy for myopia, and hyperopia correction with arcuate keratotomy [5].

Chemical compound and disease context of Keratectomy, Laser

• Paraformaldehyde-induced keratitis after photorefractive keratectomy [11].
• Eight eyes of 8 patients with compound myopic astigmatism were treated with excimer laser photorefractive keratectomy (PRK) using a hand-held ablatable mask in conjunction with the Summit excimer laser [12].
• Three patients (4 eyes) who had corneal haze of grade 2 or more underwent repeated photorefractive keratectomy and one patient (2 eyes) with steroid-induced ocular hypertension underwent trabeculectomies [13].

Biological context of Keratectomy, Laser

• SETTING: Department of Ophthalmology, Yonsei University College of Medicine, Seoul, Korea. METHODS: Myopic photorefractive keratectomy (PRK) with a 100 microm deep ablation was performed in Sprague Dawley rats killed 6, 12, 24, 48, 72, and 96 hours after the procedure [14].
• RESULTS: Keratocyte apoptosis, mediated through the release of cytokines such as soluble Fas ligand and interleukin-1 from the injured epithelium, occurs following refractive surgical procedures like photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) [15].
• Seven patients whose strabismus worsened after photorefractive keratectomy or laser in-situ keratomileusis for correction of myopia underwent orthoptic evaluation before and after refractive surgery, as well as after corrective strabismus surgery [16].

Anatomical context of Keratectomy, Laser

• OBJECTIVE: To investigate whether 193-nm excimer laser photorefractive keratectomy for the correction of myopia can determine in vivo changes in the human corneal endothelium 3 and 12 months after surgery [17].
• Central and peripheral endothelial cell changes after excimer laser photorefractive keratectomy for myopia [18].
• CONCLUSIONS: Diclofenac reduces prostaglandin E2 levels but not leukocyte infiltration in the cornea following photorefractive keratectomy and thus may be useful clinically to reduce postsurgical pain [19].
• Motivated by the alterations seen in the corneal matrix composition after photorefractive keratectomy and the migration of corneal keratocytes seen following this procedure, the locomotor response of corneal stromal fibroblasts to various extracellular matrix proteins was determined [20].
• Using ethanol applied over an 8.5-mm-diameter area for 20 seconds, the epithelium was detached and photorefractive keratectomy (PRK) was performed [21].

Associations of Keratectomy, Laser with chemical compounds

• INTERVENTION: Photorefractive keratectomy treatments with a Summit Omnimed excimer laser (6-mm) [22].
• Late corneal perforation after photorefractive keratectomy associated with topical diclofenac: involvement of matrix metalloproteinases [23].
• BACKGROUND: Replacing the gas argon fluoride (193 nm) excimer laser with a solid-state laser source in the far-ultraviolet spectrum region would eliminate the hazards of a gas laser and would reduce its size, which is desirable for photorefractive keratectomy [24].
• PURPOSE: To evaluate the refractive results of excimer laser photorefractive keratectomy (PRK) performed on normal, sighted myopic eyes; to assess the role of postoperative topical steroid treatment in patients with PRK; and to study the regression of effect [25].
• Dilute topical proparacaine for pain relief after photorefractive keratectomy [26].

Gene context of Keratectomy, Laser

• Release of TGF-beta 1 and VEGF in tears following photorefractive keratectomy [27].

• Functional outcome and satisfaction after photorefractive keratectomy. Part 2: survey of 690 patients [30].
• We present 13 patients (eight male, five female, mean age 36 years) in whom sumatriptan, a highly selective 5-HT1B/1D agonist that is normally used as a specific anti-migraine drug, was used for the treatment of pain following photorefractive keratectomy (PRK) [31].

Analytical, diagnostic and therapeutic context of Keratectomy, Laser
