Advanced corneal cross-linking system with fluorescence dosimetry.

Purpose. This paper describes an advanced system that combines corneal cross-linking with riboflavin with fluorescence dosimetry, the ability to measure riboflavin diffusion within the cornea both before and during UVA treatment. Methods and Results.

Photochemical kinetics of corneal cross-linking with riboflavin.

Purpose: To model the photochemical kinetics of corneal cross-linking with riboflavin (Rf) and confirm the model through measured oxygen concentration experiments under varying energy input conditions by UV-A irradiance and temperature modulation in ex vivo porcine cornea.

Methods: A theoretical model was developed to describe the corneal cross-linking photochemical kinetics of Rf. After instillation with drops of Rf solution in distilled water, de-epithelialized porcine corneas were exposed to 365-nm ultraviolet light (UV-A) under varying irradiance and temperature.

The effects of pulse dye laser double-pass treatment intervals on depth of vessel coagulation.

Background And Objective: Multi-pass treatments with pulse dye lasers (PDLs) are avoided due to perceived side effects. Proper multi-pass techniques allow for deeper vascular injury. New extended PDLs allow use of multi-pass procedures.

Treatment of telangiectasia using the multi-pass technique with the extended pulse width, pulsed dye laser (Cynosure V-Star).

Background: The pulsed dye laser (PDL) has been used for the treatment of facial and leg telangiectasia, where it provides safe and effective treatment. Often, a single treatment with the PDL can provide acceptable vessel clearance. Unfortunately, the hallmark of PDL treatment is transient purpura, which can be cosmetically unacceptable to patients.

Multipass treatment of photodamage using the pulse dye laser.

Background: Pulse dye lasers (PDLs) alter structural proteins in scars and photodamaged skin, in addition to their effects on dermal vasculature. The PDL has become an option in the treatment of photodamage. Although improvements to skin texture are generally modest when compared with ablative resurfacing, PDL offers a treatment with few side effects.

Evaluation of pulse-duration on purpuric threshold using extended pulse pulsed dye laser (cynosure V-star).

Background And Objectives: Pulsed dye lasers (PDL) with extended pulse-durations create new opportunities in the treatment of vascular lesions. Development of extended pulse methods requires understanding of tissue effects of extended pulse-durations. We evaluated tissue effects of extended pulse-duration PDL (EPDL) with cooling.
