Femtosecond laser-assisted cataract surgery provides surgeons an exciting new option to potentially improve patient outcomes and safety. Over the past 2 years, 4 unique laser platforms have been introduced into the marketplace. The introduction of this new technology has been accompanied by a host of new clinical, logistical, and financial challenges for surgeons. This article describes the evo...

After the invention of lasers, in the past 50 years progress made in laser-based display technology has been very promising, with commercial products awaiting release to the mass market. Compact laser systems, such as edge-emitting diodes, vertical-cavity surface-emitting lasers, and optically pumped semiconductor lasers, are suitable candidates for laser-based displays. Laser speckle is an imp...

In recent years, femtosecond lasers matured from sensitive research setups to turnkey systems for an increasing number of applications. Now that running an ultra-short pulse laser system needs no longer a specialized scientist, safety issues become more crucial. Ultrashort laser pulses have extremely high peak powers and even scattered radiation may possess severe risks to the unprotected eye. ...

In order to model the thermal effect of laser exposure of the iris during laser corneal surgery, we simulated the temperature increase in porcine cadaver iris. The simulation data for the 60 kHz FS60 Laser showed that the temperature increased up to 1.23°C and 2.45°C (at laser pulse energy 1 and 2 [micro sign]J, respectively) by the 24 second procedure time. Calculated temperature profiles show...

Several laser and non-laser refractive surgical procedures have been used to modify the shape of the cornea and correct myopia, hyperopia, astigmatism, and presbyopia. Introduction of the excimer laser to reshape the cornea has resulted in remarkable developments in the correction of these refractive errors. Combined with other advanced ophthalmological instruments, laser refractive eye surgery...

Background and Objectives: The most recent technological breakthroughs incorporated in the latest generation of Variable Square Pulse (VSP) Er:YAG dental lasers involve two additional features: SSP (Super Short Pulse) mode for extremely fine and minimally invasive laser ablation; and MAX mode for maximum optical drilling speeds. The objective of this study was to make a comparison between the t...

PURPOSE High-Performance System (HPS) laser photo vaporization of the prostate (PVP) is a widely used procedure nowadays. The safety and efficacy of the procedure has been affirmed in general patients with benign prostatic hyperplasia (BPH), but data on the safety and efficacy in specific situations, such as in patients with a large prostate, patients taking anticoagulant or 5-alpha reductase i...

We describe a case of modified femtosecond laser settings for cataract extraction in a patient with a posterior chamber phakic intraocular lens (PIOL), to avoid incomplete treatment patterns and treatment displacement. Modification of laser settings (increased depth for the capsulotomy, increased vertical spot spacing for the capsulotomy and increased anterior and posterior capsule safety margi...

This paper introduces the world’s first laser profile measurement system for the refractory lining of hot torpedo ladles, the LaCam®. The torpedo measuring system allows immersion of a laser head into a hot torpedo ladle with surrounding temperatures of more than 1,000°C. Benefits include improved safety, increased ladle availability and capacity, extended refractory life, and cost savings in e...
