BACKGROUND AND OBJECTIVE The optimized parameters of femtosecond (fs) lentotomy, an innovative strategy for presbyopia, have been further discussed regarding the safety of the procedure for eyeballs. This article's aim was to prove the safety and feasibility of the fs lentotomy procedure with 50-fs laser pulses. STUDY DESIGN/MATERIALS AND METHODS This was an experimental study in which the sa...
PURPOSE To discuss intraoperative and postoperative femtosecond laser-assisted LASIK flap complications and their management. METHODS Review of published literature. RESULTS Flap creation is a critical step in LASIK. The femtosecond laser has improved the overall predictability and safety of the lamellar incision, but complications can still occur during or after flap creation. Although man...
Laser beams for guide star generation are a potential hazard for aircraft. At the MMT telescope located on Mt. Hopkins in Southern Arizona, a constellation of five Rayleigh guide stars is created with a total of 25 W of projected power at 532 nm wavelength. We report operational results from an automatic system deployed at the MMT that is designed to detect aircraft and shut down the lasers if ...
To evaluate the safety, efficacy, advantages, and limitations of femtosecond laser-assisted cataract surgery through a review of the literature. A PubMed search was conducted using topic-appropriate keywords to screen and select articles. Initial research has shown appropriate safety and efficacy of femtosecond laser-assisted cataract surgery, with improvements in anterior capsulotomy, phacofra...
In this paper, a one-dimensional photonic crystal filter based on the [SiO2/ZrO2] bilayer have been designed for application in safety glasses for working in 350-nm wavelength. High power lasers with low wavelength e.g. 350-nm have very high power which can cause serious damage to the operator’s eyes. In this paper using the transfer matrix method and theoretical calculation in MATLAB software ...
