dye laser

a system of highly selective laser destruction of skin blemishes using various dyes at wavelengths at the longer oxygenated hemoglobin absorption peaks to overcome interference from overlying melanin.

dye laser

A laser with wavelengths of 510 nm for green and 577 nm–600 nm for yellow, whose energy reacts with various dyes and, modified by a tunable crystal, is applied in pulses, used primarily to manage skin lesions.

Patient care

Care involves giving general emotional support, explanations, and answering questions regarding the procedure. The equipment is checked, and all rules are observed. The needs of the surgeon are anticipated, and the procedure is recorded in the laser log.
