Background: To analyse the rate of complications associated with Nd YAG posterior capsulotomy. Methods: This prospective clinical study was conducted in Holy Family Hospital over a six-month period. It included five hundred and fifty patients in out door Eye Department, Holy Family Hospital treated with Nd YAG laser capsulotomy due to posterior capsular opacification after cataract surgery. The...

A congenital melanocytic nevus (CMN) is present at birth in approximately 1% of newborn infants. Treating CMN with a single laser without complications is very difficult because of the deep-penetrating nature of the nevus cells in this lesion. A 51-year-old female patient presented with a single 8 cm x 14 cm sized dark brown to black plaque with scar on the left side of face. She received 10 tr...

Demineralized enamel grooves were exposed to an acid gel at pH=5 for 3weeks after irradiation with a KrF excimer laser with a wavelength of 248nm (total energy dose= 172 J/cm2) er with the second harmonic wave of a Q-switched Nd:YAG laser with a wavelength of 532nm (totai energy dose=100JIcm2), The mineral distributions were assessed quantitatively by transversal microradiography. Compared with...

Laser welding is an advance non-traditional and high energy beam welding technique for dissimilar material, which is being increasingly used in industries like automobile, nuclear reactors, aerospace etc. Again it is a very tough task to joining dissimilar materials due to their properties variation. In this present work two dissimilar metals such as copper and AISI 304 stainless steel are take...

Free beam laser endarterectomy (LE) and contact laser endarterectomy (CLE) were compared in 15 arteriosclerotic New Zealand white rabbits. The rabbits underwent balloon catheter trauma to the thoracoabdominal aorta and were fed a 2% cholesterol diet for 18 weeks. Thoracoabdominal exploration was performed under general anesthesia and multiple endarterectomies were performed in each rabbit. Athe...

Epulis fissuratum is a mucosal hyperplasia that result from chronic irritation induced by poorly fitting prosthesis. It pseudotumor sitting in the vestibule of jaw; and composed several layers. This lesion impinges on prosthetic balance requiring pre-prosthetic surgical time. The extent this case makes it impossible to take an accurate impression for performing cicatrisation guiding Total excis...

Received for publication January’ 2009 ... ........................... Purpose. The objective of this study is to compare the frequency of Neodymium YAG laser capsulotomy in eyes receiving silicon foldable posterior chamber intraocular lenses with those receiving acrylic foldable posterior chamber intraocular lenses. Material and Methods. This Comparative study was carried out at Ophthalmology ...

In this paper, tungsten oxide thin films were successfully synthesized by the laser pulse deposition (PLD) method using a pulsed (ND-YAG) and wavelength (1064 nm) on glass substrate at different fluencies. The effect of increasing fluency, optical structural properties WO3 nanoparticle films, was investigated UV-Visible spectrophotometer, X-Ray diffraction (XRD), atomic force microscope (AFM) S...

Background: Previously described methods for removal of tattoos are chemical, mechanical, surgical, termal and laser assited methods. Invention of the Q-switch mode, advanced the laser method, to be one of the most effective methods of tattoo removal. Objective: Comparing the tattoo removal and rate of lymphatic elimination of 3 different wavelengths of Q-switched Nd-YAG laser (532nm, 1064nm, c...
