To the Editor: The corneal deposits seen in heterozygote granular corneal dystrophy type 2 (GCD2) can be observed in individuals with variable appearances.1 When the deposits are small and at times undetectable, only genetic analysis is effective for the confirmative diagnosis. Many refractive surgeons have adopted genetic testing prior to refractive surgery to verify that their patients are fr...

PURPOSE To investigate the efficacy of mitomycin C (MMC) in preventing haze formation in surface wavefront customized ablations with successful refractive treatment (laser epithelial keratomileusis [LASEK]) and to evaluate the safety of this technique on corneal stroma and endothelium. METHODS This study was a prospective, double-masked, randomized clinical trial involving 52 eyes (30 placebo...

This research focuses on four cases of patients having undergone eximer laser photorefractive surgery who were diagnosed with adenoviral keratoconjunctivitis during the postoperative period and who later developed epidemic keratoconjunctivitis (EKC)-like keratitis. Two of the patients had undergone laser-assisted subepithelial keratectomy (LASEK), one had undergone laser in situ keratomileusis ...

OBJECTIVE To develop corneal morphometric models with refractive error in excimer laser surgery. METHOD A prospective-longitudinal study was conducted on 78 patients (151 eyes) using the LASIK surgical technique, and 56 patients (111 eyes) with myopic astigmatism using ESIRIS (Schwind-Germany) equipment with pendulous microkeratome. The results were analyzed using descriptive statistics. A NI...

The nervous systems of many gastropods contain unusually large neurons . The cell bodies of these giant neurons can be more than 1 mm in diameter, as in the case of the colossal cells of Aplysia (Coggeshall, 1967) . The nucleus represents approximately 30 per cent of the volume of the giant cell body, and in Aplysia californica the amount of nuclear DNA is many thousands of times greater than t...

The aim of the present study was to determine the effect of different concentrations of mitomycin C (MMC) administered intraoperatively during laser-assisted subepithelial keratectomy (LASEK) surgery. A total of 261 patients (496 eyes) were randomly divided into two groups: 0.04% MMC treatment group consisting of 133 patients (245 eyes) and the 0.02% MMC treatment group consisting of 128 patien...

PURPOSE To evaluate the current clinical evidence of safety and efficacy of intraoperative topical application of 0.02% mitomycin C (MMC) used for up to 2 minutes after surface ablation for correction of myopia. METHODS A comprehensive literature search was conducted of Cochrane Library, MEDLINE, and EMBASE to identify relevant trials comparing surface ablation for correction of myopia with a...

Zachowane do dziś przedmioty, które zostały wykonane z bursztynu w Gdańsku drugiej połowie XVIII w., są nieliczne. Niewiele też wiadomo na temat bursztynników tym czasie i ich sytuacji materialnej. Dlatego cenne informacje archiwalne dobytku bursztynowych wyrobów należących wdowy po mistrzu bursztynniku, Johannie Ernście Dentlerze, podstawie inwentarza 1777 r. Dane te, uzupełnione o wiadomości ...
