Accidental retinal laser injuries are easily diagnosed when there are known laser sources, typical macular injuries, and visual deficits consistent with retinal findings. Decisions are more difficult when retinal findings are subtle or absent, despite reported visual problems and somatic complaints. Inaccurate diagnosis of an ocular laser injury can precipitate a costly, lengthy sequence of med...

purpose : to assess the outcomes of laser in situ keratomileusis (lasik) in patients with multiple sclerosis (ms) methods : 15 eyes of 8 patients with ms (2 men and 6 women) who referred for myopia treatment (with or without astigmatism) were undergone lasik. after refractive and visual acuity examinations, topographic and pachymetry screening, intraocular pressure (iop) measurement, biomicrosc...

introduction: tooth pain and sensitization are the two main causes of discomfort after periodontal flap surgery. effects of low level laser therapy for reducing pain have already been established; these kinds of lasers have been used for tooth desensitization as well. this controlled blind study sought to compare tooth pain and sensitization after 660nm laser irradiation in a split mouth and al...

patient with diabetes, you should remember that cataract surgery may make diabetic retinopathy worse. Eyes with mild to moderate non-proliferative diabetic retinopathy at the time of surgery are considered less at risk. Those with severe non-proliferative and proliferative diabetic retinopathy have a higher risk of progressive disease.1 Clinically significant macular oedema (CSMO) present at th...

Introduction: To present and assess a newly designed autoclavable, reusable tube shield for an endotracheal tube (ETT) during laser laryngeal surgery.   Materials and Methods: This study included patients scheduled for endolaryngeal laser surgery. A carbonated stainless-steel hemisphere shield (~1.5×0.6 mm) connected to a silk thread passing through a hole in its middle near upper edge was ...

The history of refractive eye surgery is recent, but has seen rapid advancement. Older technologies, such as radial keratectomy, had the problem of overcorrection and epithelial complications. Newer technologies, such as photorefractive keratectomy, laser-assisted in-situ keratomileusis (LASIK) and laser-assisted subepithelial keratomileusis (LASEK), which require the use of laser, has revoluti...

Objective: To describe results of barrier laser photocoagulation in preventing progression of recurrent retinal detachment. Methodology: Prospective review of five patients with recurrent retinal detachment confined to the peripheral inferior retina. Three rows of barrier argon laser photocoagulation of moderate intensity white burns were performed. Patients were observed carefully after laser ...

INTRODUCTION To evaluate the vitreoretinal complications in myopes after Visian implantable collamer lenses (ICL) implantation. MATERIALS AND METHODS This is a retrospective, observational, non-comparative clinical study that evaluated 617 consecutive myopes who underwent ICL implantation at the Department of Refractive Surgery, Yemen Magrabi Hospital, Sana'a, Yemen between July 2006 and May ...

PURPOSE To evaluate the effectiveness of laser photocoagulation as adjuvant therapy in the treatment of large macular holes. METHODS A randomized clinical trial. Thirty-one eyes from 29 subjects with idiopathic macular holes of diameters larger than 400 microm were randomized into a laser group and a control group. All eyes underwent vitrectomy with peeling of the internal limiting membrane. ...

In femtosecond laser ophthalmic surgery tissue dissection is achieved by photodisruption based on laser induced optical breakdown. In order to minimize collateral damage to the eye laser surgery systems should be optimized towards the lowest possible energy threshold for photodisruption. However, optical aberrations of the eye and the laser system distort the irradiance distribution from an ide...
