BACKGROUND The purpose of this study was to evaluate the safety and efficacy of ultraviolet A irradiation cross-linking on completion for cases of high myopic laser-assisted in situ keratomileusis (LASIK). METHODS Forty-three consecutive LASIK cases treated with femtosecond laser flap and the WaveLight excimer platform were evaluated perioperatively for uncorrected visual acuity, best correct...

A 74-year-old man presented to the ophthalmology outpatient clinic with reduced visual acuity and increasing haziness of vision in his left eye over several months. Seven years previously he had undergone uneventful cataract surgery with phacoemulsification and insertion of a posterior chamber lens (+14.5 dioptres Alcon MA60BM, 6.0 mm optic) in the same eye. There had been no postoperative comp...

PURPOSE To evaluate macular function by focal electroretinography and fluorescein angiography (FA) in patients with neovascular age-related macular degeneration submitted to verteporfin photodynamic therapy (VPT). METHODS Prospective study involving 22 patients with age-related macular degeneration and predominantly classic subfoveal neovascular membrane, in non consecutive series, treated wi...

BACKGROUND This paper reports population-based data on the prevalence and causes of visual impairment among children and adults in Botucatu, Brazil. METHODS A population-based cross-sectional study was conducted involving a random start point and then systematic sampling of an urban Brazilian population in the city of Botucatu. There were approximately 3,300 individuals aged 1 to 91 years who...

PURPOSE Diabetic macular edema can be refractory to multiple treatment modalities. Although there have been anecdotal reports of ranibizumab showing efficacy when other modalities provided limited benefit, little has been published on treatment for refractory diabetic macular edema. This study sought to investigate this observation further. METHODS Retrospective chart review. RESULTS Thirty...

AIM To assess the refractive outcome of clear lensectomy combined with piggyback intraocular lens implantation in highly hyperopic patients. METHODS This case review included 19 eyes of 10 patients with high hyperopia and axial length less than 21mm. Intraocular lens power was calculated for emmetropia using the Holladay II formula in 17 eyes, and SRK/T formula in 2 eyes following clear lens ...

OBJECTIVE To evaluate the safety, efficacy, predictability, and long-term stability of the Artisan Phakic Intraocular Lens (Ophtec BV, Groningen, the Netherlands) for the correction of high myopia. METHODS Prospective analysis of 26 eyes from 15 patients who underwent placement of the Artisan lens for the correction of high and extreme myopia. The mean (SD) preoperative spherical equivalent w...

PURPOSE The aim of this study is to assess whether eye dominance may change after cataract surgery. METHODS This is a prospective case series. Cataract surgery candidates were examined prior to surgery for best-corrected visual acuity, eye dominance, and handedness. Patients with ocular conditions that may affect visual acuity were excluded from the study. A month following surgery, best-corr...

PURPOSE To evaluate the efficacy and safety of laser-assisted subepithelial keratectomy (LASEK) for the treatment of myopia and astigmatism (low, moderate and high). MATERIAL AND METHODS Laser-assisted subepithelial keratectomy was performed by 3 surgeons in 45 eyes using an INPRO Gauss Excimer laser (31 eyes) or a NIDEK EC-5000 Excimer Laser (14 eyes). The mean follow-up is 9 months (3-15 mo...

purpose : to evaluate the effectiveness of intravitreal triamcinolone acetonide on visual acuity and macular thickness using optical coherence tomography in macular edema associated with nonischemic central retinal vein occlusion (crvo). design : a prospective interventional case series. patients & methods : twenty eyes of 25 patients with nonischemic crvo and macular edema with visual acuity o...
