Pulsed intense light to treat dry eye syndrome

Intense Pulsed Light (IPL) is the therapeutic tool implemented in the treatment of dry eye, characterized by the emission of waves of 500-1200nm in the region of the upper and lower eyelids. Dry eye is a recurring complaint in ophthalmology offices and has an impact on the patient's quality of life. It results from dysfunction of the meibomian glands, duct obstruction, and quantitative and qualitative changes in glandular secretion. It is manifested by dryness and irritation, foreign body sensation, burning, tearing, and eye fatigue. The available treatments are short term palliative with unsatisfactory results. To determine through a literature review, the benefit of using intense pulsed light for dry eye treatment. Methodology: We searched the Cochrane database, PubMed, Embase, Scopus, Web of Science, and Google Scholar (gray literature) using the keywords for an independent, blinded, peer-reviewed selection of articles to be met following pre-established criteria. Studies evaluated the use of IPL in patients with dry eye, despite the benefit found, focus on the objective and subjective assessment of the eye more frequently. Evidence-based clinical guidelines are required for the use of intense pulsed light in the treatment of Meibomian Gland Dysfunction (MGD), as well as a device and algorithm for indications of therapeutic use.
