Disease relevance of Keratotomy, Radial

• CONCLUSIONS: Severe bacterial endophthalmitis can occur after radial keratotomy surgery, even in the absence of microperforation during the procedure [1].
• Two-incision radial keratotomy for low myopia with astigmatism [2].
• We present two successful cases of epikeratophakia following refractive keratoplasty: one following radial keratotomy for myopia and one following penetrating keratoplasty for keratoconus [3].
• CONCLUSIONS: Nonpreserved ketorolac tromethamine 0.5% ophthalmic solution was significantly more effective than, and as safe as, vehicle in the treatment of postoperative pain associated with radial keratotomy [4].
• As compared to radial keratotomy (RK) in which the postoperative refractive error drifts relentlessly in the hyperopic direction, PRK brings about an initial hyperopic shift followed by regression leading to increasing myopia [5].

High impact information on Keratotomy, Radial

• The Prospective Evaluation of Radial Keratotomy Study is a nine-center clinical trial of a surgical technique to reduce simple myopia by making incisions in the cornea [6].
• Results of the Prospective Evaluation of Radial Keratotomy (PERK) Study 4 years after surgery for myopia. Perk Study Group [6].
• In spite of previous reports of positive results with BAPN, neither BAPN nor penicillamine was found to affect keratometry readings or corneal topography after radial keratotomy [7].
• The inhibition of collagen cross-linkage by beta-aminopropionitrile (BAPN) and D-penicillamine was tested in an attempt to enhance the myopic correction achieved by radial keratotomy [7].
• CONCLUSION: The combined-technique of radial keratotomy, coupled with the Genesis surgical protocol, affords centrifugal incision safety with centripetal incision efficacy [8].

Biological context of Keratotomy, Radial

• In the period after surgical correction of myopia and astigmatism in 30 patients (44 eyes) by radial keratotomy, contrast sensitivity deteriorated slightly [9].
• CONCLUSIONS: The shift toward hyperopia and myopia in an individual suggest that instability of the radial keratotomy wound may be related to local wound healing events that are, in part, related to incision depth [10].
• RESULTS: The most common causes of medical litigation in ophthalmology are related to LASIK surgery, cataract surgery, glaucoma care, radial keratotomy for myopia reduction and failure to diagnose binocular vision anomalies in children and adults in a timely fashion [11].

Anatomical context of Keratotomy, Radial

• The 193-nm ultraviolet beam from an argon fluoride excimer laser was focused on the corneas of rabbits to produce incisions of the type necessary for radial keratotomy [12].

Associations of Keratotomy, Radial with chemical compounds

• Two groups of six rabbits each underwent radial keratotomy in both eyes; one eye of each rabbit was treated with BAPN (33% in white petrolatum) or D-penicillamine (1.5 M in sterile water) three times a day for 6 weeks, while the other eye received only vehicle [7].
• Effect of topical diclofenac solution on discomfort after radial keratotomy [13].
• PURPOSE: To investigate the efficacy and safety of nonpreserved ketorolac tromethamine 0.5% ophthalmic solution in relieving pain following radial keratotomy (RK) [14].
• Efficacy and safety of nonpreserved ketorolac ophthalmic solution in postoperative ocular pain following radial keratotomy [14].
• Radial keratotomy redux [15].

Gene context of Keratotomy, Radial

• Radial keratotomy: analysis of efficacy and predictability in 1,058 consecutive cases. Part II: Predictability [16].
• Extracellular matrix and basement membrane alterations were identified in human corneas after radial keratotomy [17].
• The slit-scan system showed better correlation with the Placido system in the preoperative and postoperative radial keratotomy group (R=0.73) than in the group that included postoperative PRK eyes (R=0.69) [18].
• BACKGROUND: We analyzed retrospectively the refractive and visual results of a cohort of patients who underwent radial keratotomy for myopia 10 years ago [19].
• We performed radial keratotomy using the Fyodorov techniques on 14 Eye Bank eyes [20].

Analytical, diagnostic and therapeutic context of Keratotomy, Radial

• PURPOSE: To evaluate the safety, efficacy, and complications of radial keratotomy (RK) after photorefractive keratectomy (PRK) for myopia [21].
• As the use of radial keratotomy (RK) to correct myopia increases, more patients are having penetrating keratoplasty (PK) [22].
• PURPOSE: To evaluate the results of combining laser in situ keratomileusis (LASIK) and radial keratotomy (RK) for the correction of moderate to high myopia [23].
• SETTING: Rancho Bernardo Eye Center, San Diego, California. METHODS: This retrospective study comprised 86 eyes of 60 consecutive patients who received enhancements to reduce residual myopia (mean 1.30 diopters [D] +/- 0.50 [SD]; range 0.75 to 3.00 D) after primary radial keratotomy (RK) [24].
• Fluorophotometry performed in a second group of animals at varying intervals following radial keratotomy showed no probable physiologically important change in endothelial fluorescein permeability [25].
