Laser trabeculoplasty has an increasing important role in the management of glaucoma as more emphasis is placed on minimally invasive therapies. In recent years, the following laser trabeculoplasty technologies have been introduced: micropulse laser trabeculoplasty, titanium-sapphire laser trabeculoplasty and pattern scanning trabeculoplasty. These lasers help to reduce the intraocular pressure...

purpose: to compare the safety, efficacy, predictability, stability and complications of wavefront-guided laser-assisted subepithelial keratectomy (lasek) in low myopia, myopic astigmatism and high myopia correction. methods: in his retrospective study, 416 eyes were divided to 3 groups: 159 eyes with low myopia (lm) and mean refractive spherical equivalent (mrse) of -3.68±1.33 (sd) diopter (d)...

PURPOSE OF REVIEW Methods of flap creation have changed over the years from the evolution of the mechanical microkeratome to the introduction of the IntraLase femtosecond laser keratome, both of which have different mechanisms of action to create corneal resections. Previous studies report the advantages and disadvantages of the mechanical microkeratome and the IntraLase femtosecond laser. The ...

Laser sources are nowadays largely adopted in medicine and hence they are widespread in medical environment, where patients are present and the users are not always highly specialized in managing laser sources. This has greatly boosted the attention towards safety issues related to exposure to laser beams and to strictly assess the values of well defined laser radiation standard parameters char...

purpose: to determine if intravitreal injection of triamcinolone acetonide is safe and effective in the treatment of diabetic macular edema unresponsive to prior laser photocoagulation. methods: fifty-four eyes of 38 patients with clinically significant macular edema which had received at least two sessions of laser photocoagulation according to early treatment diabetic retinopathy study guidel...

introduction: basal cell carcinoma (bcc) is the most common cutaneous malignancy. proffered treatment for these lesions is surgery. based on patient’s age, drug allergies, and place of lesions, surgery may not be the best option, and alternative treatments should be considered. pulsed dye laser (pdl) may be a good alternative therapy. the aim of the present study was to determine the effectiven...

Introduction The 308 nm excimer laser is a widely used device throughout the field of dermatology for many diseases including psoriasis. Although the laser has demonstrated clinical efficacy, there is a lack of literature outlining the safety, efficacy, and patient acceptability of the excimer laser. Methods A literature search on PubMed was used with combinations of the terms "excimer", "exc...

BACKGROUND The purpose of this work is to report our experience using the new Z8 laser system for femtosecond laser-assisted cataract surgery (FLACS) and to provide a sample of the performance and safety results using this new technology. METHODS This prospective observational study was performed at the Swiss Eye Research Foundation, Eye Clinic ORASIS, Reinach, Switzerland. Fourteen patients ...
