1. Pain response and symptoms in photorefractive keratectomy: mechanical de-epithelization compared with transepithelial ablation
RESUMO Objetivo: Comparar a dor e o desconforto da cera tectomia fotorefrativa mecânica vs transepitelial. Métodos: Este estudo comparativo prospectivo incluiu 190 olhos de 95 pacientes com hipermetropia, astigmatismo e miopia que foram submetidos a ceratectomia fotorefrativa mecânica em um olho e ceratectomia fotorefrativa transepithelial no olho contr

2. Laser topoguiado como tratamento de ectasia pós lasik
RESUMO O laser in situ keratomileusis (LASIK) é o método cirúrgico refrativo mais realizado no mundo com excelentes resultados, porém tal método não é isento de riscos. A ectasia pós LASIK é uma complicação grave e se caracteriza por um aumento progressivo da curvatura e afinamento da córnea, resultando em astigmatismo irregular e diminuição da

3. Estudo comparativo entre a ceratectomia fotorrefrativa e a ceratomileusis in situ a laser guiadas pela análise de frente de onda / Comparative study between wavefront-guided photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK)
PURPOSE: To compare clinical results of two wavefront-guided treatments, photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK), for low to moderate myopia correction, with or without astigmatism. SETTING: Refractive Surgery Service, General Hospital, University Of São Paulo, São Paulo, Brazil. METHODS: Prospective randomized study of 7

4. Análise dos resultados de ceratectomia fotorrefrativa com mitomicina C e LASIK para correção miópica. / Analysis of photorefractive keratectomy with mitomycin C and LASIK results for myopic correction.
Objetivos: Comparar os resultados de acuidade visual, refração estática, aberrometria e sensibilidade ao contraste em olhos com miopia moderada submetidos à ceratectomia fotorrefrativa (PRK) com mitomicina C (MMC) ou à ceratomileuse assistida por excimer laser in situ (LASIK) em cirurgias guiadas por frente de onda durante acompanhamento de um ano.

5. Comparative study between photorefractive keratectomy (PRK) and butterfly laser-assisted subepithelial keratectomy (BLASEK) / Estudo comparativo entre a ceratectomia fotorrefrativa (PRK) e a ceratectomia subepitelial borboleta assistida a laser (LASEK borboleta)
PURPOSE: Comparatively evaluate the results of two techniques of surface excimer laser refractive surgery, photorefractive keratectomy (PRK) and butterfly laser-assisted subepithelial keratectomy (BLASEK). SETTING: Sadalla Amin Ghanem Eye Hospital, Joinville, Santa Catarina, Brazil. METHODS: This is a prospective, randomized and double-masked study including

6. LASIK X PRK após cirurgia de descolamento de retina
OBJETIVO: Comparar os resultados obtidos pelas técnicas de "laser in situ keratomileusis" (LASIK) e "photorefractive keratectomy" (PRK) na correção de miopia e astigmatismo em olhos previamente submetidos à cirurgia de descolamento de retina (DR) com "buckle" escleral. MÉTODOS: Vinte e cinco olhos de 22 pacientes com alterações refracionais significat

8. Refractive and visual results and patient satisfaction after excimer laser photorefractive keratectomy for myopia.
A study of excimer laser photorefractive keratectomy was performed on 108 patients. Variation in individual refractive outcome was noted, particularly for the higher levels of correction. At 12 months, of those with up to 3 dioptres of myopia, 93% were within 1 dioptre of emmetropia, 100% achieved an acuity of 6/12 unaided, 69% were very pleased with their r

9. Role of epithelial hyperplasia in regression following photorefractive keratectomy.
AIM--To determine the relation between epithelial hyperplasia and regression of effect after photorefractive keratectomy (PRK). METHODS--Seventy unilaterally treated patients with PRK were examined. All eyes had been treated with the Summit excimer laser 27 (SD 7) months previously with zone diameters of 4.1 to 5.0 mm. The untreated fellow eyes served as con

10. Excimer retreatment for scarring and regression after photorefractive keratectomy for myopia.
AIMS/BACKGROUND--Scarring associated with regression of refractive effect can occur after photorefractive keratectomy (PRK) for myopia. The experience of treating these complications is reported. METHODS--Eighteen of 285 eyes (6.3%) were retreated with the excimer laser. Age, sex, preoperative primary treatment keratometry, pre-primary treatment, pre-retreat

11. Excimer laser photorefractive keratectomy for patients with contact lens intolerance caused by dry eye.
AIMS/BACKGROUND: To evaluate epithelial wound healing and visual outcome of excimer laser photorefractive keratectomy (PRK) performed on high myopic eyes with contact lens intolerance due to dry eye. METHODS: PRK was performed on two groups of patients with non-Sjogren's dry eye: group A (-6 D to -9.5 D, 11 patients, 17 eyes) and group B (-11.5 D to -19.5 D,

12. Expression of cellular fibronectin and tenascin in the rabbit cornea after excimer laser photorefractive keratectomy: a 12 month study.
An indirect immunohistochemical technique was used to monitor the expression of cellular fibronectin (cFN) and tenascin (TN) in the rabbit cornea after photorefractive keratectomy (PRK) in a 1 year follow up study. Rabbits received a 5.0 D myopic PRK, and were killed 3 days, 1, 3, 6, or 12 months after the operation. In most corneas, secondary epithelial def
