OBJECTIVE To evaluate safety, efficacy, predictability, stability, complications, and patient satisfaction after implantation of Artisan toric phakic intraocular lenses (TPIOLs) for the correction of myopia or hyperopia with astigmatism. DESIGN Prospective, nonrandomized, comparative (self-controlled) multicenter trial. PARTICIPANTS Seventy eyes of 53(More)
AIMS This study was designed to investigate the therapeutic potential of excimer laser for recurrent painful erosions in patients not suited to treatment with penetrating keratoplasty. METHODS Phototherapeutic keratectomy (PTK) with the excimer laser was performed prospectively on a series of 13 eyes of 12 patients with recurrent corneal erosions in(More)
We studied a family with pattern dystrophy of the retina (PDR) in order to elucidate the clinical course of the disorder, relations between the different forms, and the mode of inheritance. Thirty-nine family members, representing three generations, underwent a thorough ophthalmological examination, with fluorescein angiography whenever a macular(More)
At least 13 independent tRNAVal gene loci were detected in the human genome. Three of these genes were isolated and shown to occur only once in the haploid genome. No further functional tRNA genes are located on the isolated clones. Two tRNAVal genes encode the known major and minor tRNAVal isoacceptors, the third may be a pseudogene because a corresponding(More)
BACKGROUND The treatment of patients with recurrent erosions due to bullous keratopathy is disappointing in cases when penetrating keratoplasty cannot be performed. A trial has been made to prevent recurrent erosions through the smoothing of the cornea with the excimer laser. METHODS Excimer laser phototherapeutic keratectomy (PTK) was performed after(More)
stated in the discussion in the article, dextran has an important role in intraoperative corneal dehydration, reducing corneal thickness and facilitating CXL action in the deeper stroma. Intraoperative pachymetry was performed in some, but not all of our cases and clearly showed progressive thinning of the corneas, which also became more transparent,(More)
