BACKGROUND The aim of this study was to perform the first femtosecond laser cuts with a new prototype femtosecond laser, in vivo and to evaluate its safety, stability and efficacy. METHODS A LASIK cut was performed with a prototype 200 kHz femtosecond laser in both eyes of nine patients and one eye of two patients (20 individual eyes in total). A complete ophthalmic examination was performed ...

PURPOSE To evaluate the efficacy and safety of sustained-delivery fluocinolone acetonide (FAc) intravitreal implant for diabetic macular edema (DME). PATIENTS AND METHODS Prospective study in patients with DME insufficiently responsive to laser and anti-vascular endothelial growth factor (anti-VEGF). Patients with history of rise of intraocular pressure after intravitreal corticosteroids were...

Purpose. To evaluate the long-term efficacy, accuracy, stability, and safety of hyperopic laser in situ keratomileusis (LASIK) using a 213 nm wavelength solid-state laser. Methods. This prospective noncomparative case series consisted of 34 eyes of 17 patients which underwent hyperopic LASIK using a 213 nm solid-state laser (Pulzar Z1, CustomVis) at an outpatient refractive surgery center in Ma...

PURPOSE The evaluation of the safety, efficacy, and long-term stability of LASIK procedures utilizing novel platform comprising a femtosecond and excimer laser and multiple networked diagnostics. SETTING Private clinical ophthalmology practice. PATIENTS AND METHODS In consecutive cases of myopic LASIK procedure with a novel refractive platform (FS200 Femtosecond and EX500 Excimer Laser), 19...

BACKGROUND AND OBJECTIVE Innovations in lasers, light and radiofrequency devices have allowed for improved therapeutic efficacy and safety and the ability to treat patients with an ever-increasing number of medical and aesthetic indications. Safety remains a primary concern and the timely communication of complications and their management is vital to insure that treatments be as safe as possib...

A systematic review of the 2.1 mu holmium-YAG laser for gall stone lithotripsy was undertaken. This infrared laser, which can be used endoscopically and percutaneously, has safety advantages over other lasers and has potential as a general purpose vascular and surgical tool. Twenty nine gall stones (mean mass 1.3 g) were fragmented in vitro using pulse energies of 114 to 159 mJ/pulse at 5 Hz wi...

A prospective controlled randomized trial was performed in order to assess the effectiveness and safety of photodynamic therapy versus laser resection in 31 patients with partial or complete tracheobronchial obstruction due to inoperable non-small cell lung cancer. Fourteen patients received dihaematoporphyrin ether and argon dye laser photoradiation, and 17 patients received Nd-YAG laser resec...

PURPOSE To evaluate the efficacy and safety of topographically guided excimer laser photoablation to retreat unsuccessful myopic and hyperopic photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). SETTING Eye Clinic, San Salvatore Hospital, University of L'Aquila, L'Aquila, Italy. METHODS At least 3 months after primary PRK (Group A) or primary LASIK (Group B), 48 eyes...

Abstract The article describes the laser safety classification of a toy for children equipped with aimer/illuminator two radiation sources. Following rules presented in EN 60825-1: 2014 standard, tests and measurements accessible emission were carried out class product was determined to be 3R. It shown that does not comply requirements 62115: 2020 standard Public Health England Guidance. potent...
