PURPOSE To evaluate the safety, selectivity, and healing of retinal lesions created using a continuous line scanning laser. METHODS A 532-nm Nd:YAG laser (PASCAL) with retinal beam diameters of 40 μm and 66 μm was applied to 60 eyes of 30 Dutch-belted rabbits. Retinal exposure duration varied from 15 μs to 60 μs. Lesions were acutely assessed by ophthalmoscopy and fluorescein angiography. Ret...

Light amplification by stimulated emission of radiation (laser) sources has many advantages for use in high-data-rate optical wireless communications (OWCs). In particular, the low-cost and high-bandwidth properties laser sources, such as vertical-cavity surface-emitting lasers (VCSELs), make them attractive future indoor OWCs. order to be integrated into networks, should conform eye safety reg...

Laser systems and other energy sources for home use are being developed and will have an exponential growth in the coming years. It is in the field of laser hair removal and hair regrowth where these lasers and intense pulsed light systems for home use are gaining most ground. There are few studies supporting their efficacy and safety and there are still no long term studies. Currently these sy...

This paper explores the technical feasibility of five functions of driving assistance systems to contribute to road traffic safety, to reach stated EU road traffic safety targets. Enabling technologies, their maturity level and development path, with a view on possible large-scale implementation, are addressed. State-of-the-art and potential of enabling technologies like positioning, radar, las...

The retinal damage effects induced by transitional near-infrared (NIR) lasers have been investigated for years. However, the damage threshold dependence on exposure duration has not been revealed. In this paper, the in-vivo retinal damage ED50 thresholds were determined in chinchilla grey rabbits for 1319 nm laser radiation for exposure durations from 0.1 s to 10 s. The incident corneal irradia...

PURPOSE To investigate the safety, efficacy, and stability of photorefractive keratectomy (PRK) performed with a newly developed solid-state laser after 1-year follow-up. METHODS The all-solid-state, Q-switched, frequency-shifted laser (LaserSoft; Katana Technologies, Berlin, Germany) with a Gaussian spot diameter of 0.2 mm and repetition rate of 1 kHz was used. Eleven eyes of six patients we...

AIM To report the visual and clinical outcomes of a pilot study of subthreshold diode micropulse (SDM) laser photocoagulation for clinically significant diabetic macular oedema (CSMO). METHODS The results of infrared (810 nm) SDM laser photocoagulation for CSMO were retrospectively reviewed in 95 eyes of 69 consecutive patients with mild to moderate non-proliferative diabetic retinopathy. The...

PURPOSE The main aim of this study was to compare the efficacy, safety, and predictability of femtosecond laser-assisted in situ keratomileusis performed by two different laser suites in the treatment of myopia for up to 6 months. METHODS In this two-site retrospective nonrandomized study, myopic eyes that underwent laser-assisted in situ keratomileusis using IntraLase FS 60 kHz formed group ...

Ophthalmology was the first medical specialty to adopt lasers right after their invention more than 50 years ago, and they gradually revolutionized ocular imaging, diagnostics, therapy, and surgery. Challenging precision, safety, and selectivity requirements for ocular therapeutic and surgical procedures keep advancing the laser technologies, which in turn continue enabling novel applications f...

Cataract surgery is the most common surgical procedure and femtosecond laser assisted cataract surgery (FLACS) has gained increased popularity. FLACS requires the application of a suction device to stabilize the laser head and focus the laser beam accurately. This may cause a significant escalation in intra-ocular pressure (IOP), which poses potential risks for patients undergoing cataract surg...
