Posterior capsular opacification, also known as after cataract develops in 33 % of patients after uneventful cataract surgery. Nd-YAG Laser capsulotomy is the treatment of choice for PCO and is routinely performed by the general ophthalmologist on an OPD basis. Endophthalmitis, although a rare complication after Nd-YAG Laser capsulotomy, has been reported in the literature. We report a case of ...

An infrared high-brightness light source based on supercontinuum generation through a SF6 photonic crystal fiber seeded by a Cr(4+):YAG femtosecond oscillator is developed for high resolution multiplex spectroscopy in the 1.5 μm region. Moreover, a multiplex high resolution approach based on a Cr(4+):YAG frequency comb enables to probe large spectral domains, with simultaneous sensitive measure...

OBJECTIVE To report recurrent herpetic keratouveitis following YAG laser peripheral iridotomy. METHODS Case report. RESULTS A 64-year-old woman with a history of dendritic keratitis underwent Nd:YAG laser peripheral iridotomy and developed geographic epithelial keratitis with stromal keratouveitis. Culture of a corneal swab grew herpes simplex virus type I. Keratouveitis subsided with acycl...

Ten eyes of nine patients were treated for very disturbing vitreous floaters with the technique of Nd-YAG laser vitreolysis. The Scanning Laser Ophthalmoscope (SLO) was used to objectivate the position, the size and the motility of the vitreous floaters with respect to the patient's visual axis, which can be precisely located with the SLO. With this technique it was possible to define more prec...

Al2O3-YAG-ZrO2 eutectic ceramic rods of 5 mm in diameter were grown by micro-pulling down technique. The seeding and the solidification rate affect microstructure, morphology, crystallography, thermal stress solidified ceramics. ternary through zirconia (111) seed had inhomogeneous irregular cellular microstructures. At stationary stable regime, microstructure spacing (λ) depends on pulling (v)...

Background: Although cryotherapy has been reported as atechnique for depigmenting residual pigmented patches inpatients with universal vitiligo, Q-switched Nd-YAG lasershave not yet been used for this purpose. The aim of this studywas to compare the efficacy of cryotherapy with that of 532nmQ-switched Nd-YAG laser therapy for depigmentation in patientswith universal vitiligo.Method: Six adult p...

OBJECTIVE Becker's nevus (BN) is a benign cutaneous hamartoma. Although different types of lasers have been used to treat the pigmentary part of BN, to date, no definite treatment modality has been determined. The objective of this study is to evaluate the efficacy and safety of erbium: yttrium aluminum garnet (Er: YAG) laser treatment among Saudi patients with BN. PATIENTS AND METHODS A seri...

Er-YAG laser irradiation has been claimed to improve the adhesive properties of dentin. We tested the hypothesis that dentin adhesion is affected by Er-YAG laser conditioning. Superficial or deep dentin from human molars was: (a) acid-etched with 35% H3PO4; (b) irradiated with an Er-YAG laser (KaVo) at 2 Hz and 180 mJ, with water-cooling; and (c) laser- and acid-etched. Single Bond (3M ESPE) an...
