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...

Telephony is an Internet application that has the potential to radically alter the telecommunications environment. This application may a ect traditional regulatory structures, subsidy structures, business models, etc. Today, users can transmit telephone-like voice tra c over the Internet at zero incremental price, unlike circuit switched telephony, which has a per-minute incremental price. Whi...

INTRODUCTION The Q-switched 1064-nm laser is associated with rapid vaporization and thermal expansion stresses leading to skin mechanical damage and is typically used for correction of exogenous and endogenous deep pigmentation. Giving the common place of fractional, infrared-domain milliseconds non-ablative lasers in aesthetic dermatology, a novel non-ablative fractional Q-switched 1,064-nm la...

A single-transverse-mode Q-switched Nd-glass laser, which can operate over a variable number of longitudinal modes, has been used to investigate the influence of the temporal nature of the laser pulse on the multiphoton ionization probability of xenon atoms. For a seven-mode laser pulse, the number of ions formed is increased by several orders of magnitude over that produced by a single-longitu...

A 75-year-old woman with corneal argyrosis was treated by a Q-switched Nd-YAG laser iridotomy after acute angle closure glaucoma. Each laser shot caused clearance of the argyrotic deposits anterior to the iridotomy site. The same effect was seen when a preventive iridotomy was performed in the other eye. The areas of clear cornea remained unchanged for a follow-up period of eight months.

Correspondence Intralenticular haemorrhage complicating pulsed laser iridotomy SIR, The pulsed laser has recently been described as a 'non-surgical' means of producing a peripheral iridotomy. The complications of this procedure have been reviewed' and include iritis, pigment dispersion, haemorrhage, transient elevation of intraocular pressure, corneal or lens damage, lack of patency of the irid...
