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...

A prismless ultrafast Cr4*:YAG laser has been designed and constructed. Intracavity dispersion in this laser is compensated through the use of double-chirped mirrors, in contrast to previous work, which used fused silica prisms. The resonator design for Kerr lens modelocking has been optimized through the use of numerical simulation programs, based on the ABCD transfer matrix formalism. Pulses ...

Introdução: Na endodontia os lasers de alta potência têm sido utilizados principalmente na desinfecção do sistema canais radiculares em cirurgia parendodôntica.Objetivo: apresentar um caso clínico parendodôntica utilizando o laser Er: YAG e as suas vantagens desvantagens neste emprego.Metodologia: Neste caso, dente 22 foi diagnosticado com abcesso periapical crônico. Realizou-se a acesso prepar...

In order to compare the retinal effects of the frequency-doubled YAG laser (532 nm) with those of argon laser, rabbit eyes were exposed to green YAG laser irradiation and processed for light and electron microscopic study at 24 hr, 2 weeks and 4 weeks. Detailed analysis was conducted on tissue exposed to 7.3 and 7.6 millijoules (mj). Response of the photoreceptors and retinal pigmented epitheli...

Objective. The influence of Coherent Ultrapulse, TruPulse and Erbium: YAG laser skin resurfacing on survival of the skin flaps when performed simultaneously was evaluated. Material and methods. We used twelve female Yucatan minipigs in the study. Skin flaps including paniculus carnosus were raised on the animals’ back. The flaps were sutured into the defect under tension. We designed 4 experime...
