STATEMENT OF PROBLEM The osseointegration of dental implant is related to their composition and surface treatment. Titanium zirconium (TiZr) has been introduced as an alternative to the commercially pure titanium and its alloys as dental implant material, which is attributed to its superior mechanical and biological properties. Surface treatments of TiZr have been introduced to enhance their os...

OBJECTIVE To determine the frequency of raised intraocular pressure (IOP) after Nd: YAG laser posterior capsulotomy and its association with the energy used with raised versus normal intraocular pressure in pseudophakes. STUDY DESIGN Comparative, cross-sectional study. PLACE AND DURATION OF STUDY Ophthalmology Department, PNS Shifa Hospital, Karachi, from August 2008 to February 2009. MET...

Cr-Tm-YAG, Cr-Tm-Ho-YAG, and Er-YAG lasers at 2.01 pm, 2.1 2pm, and 2.94 pm, resp., are compared regarding single-shot and high-repetition rate efficiency. The 2 pm lasers are intrinsically limited at higher operation temperatures, the Er-laser only shows thermal lensing. Th~n (3 mm) Tmand Ho-laser rods allow high repetition rates (30 Hz) and with increasing rod diameters pulse energies up to 1...

BACKGROUND Long-pulsed Nd : YAG laser has been used in treating larger and deep-seated leg veins. OBJECTIVE This study investigated the effectiveness and safety of long-pulsed Nd : YAG laser to treat alae nasae and nasal tip telangiectasia. METHODS Twelve patients were evaluated in a prospective IRB approved study. They had a history of previous unsatisfactory treatments with pulsed dye las...

BACKGROUND According to the high prevalence of myopia in Taiwan, we analyze the adopted cataract extractions, identify predicting factors for postoperative vision, and to assess the incidence of retinal complications after Nd: YAG laser capsulotomy in high myopic eyes. METHODS One hundred and twenty-five eyes, which the axial lengths were longer than 26 mm, following cataract extraction were ...

BACKGROUND Nepalese population with Fitzpatrick skin types III-V has high prevalence of pigmentary disorders and it is a growing cosmetic concern. Q-Switched Neodymium- Doped Yttrium Aluminum Garnet (QS Nd-YAG) laser is an efficacious tool in the treatment of pigment disorders. OBJECTIVE To highlight the efficacy and safety profile of various pigment disorders. METHODS A prospective study d...

introduction: the unprotected eye is extremely sensitive to laser radiation and can be permanently damaged from direct or reflected beams. the area of the eye damaged by laser energy is dependent upon the wavelength of the incident laser beam, duration of exposure and tissue characteristics. this study aims to investigate the effect of intense green light from doubled frequency neodymium-doped ...

introduction: human eye is a sensitive part of human body with no direct protection and due to its lack of protection against the external heat waves, studying the temperature distribution of heat waves on the human eye is of utmost importance. various lasers are widely used in medical applications such as eye surgeries. the most significant issue in the eye surgeries with laser is estimation o...
