Pulse for treating meibomian gland dysfunction, modulation method and treatment method

Abstract

The invention discloses a pulse for treating meibomian gland dysfunction, a modulation method and a treatment method. The pulse for treating meibomian gland dysfunction comprises pulse clusters with the energy range of 5-15 J / cm<2>, each 0.5 J / cm<2> pulse cluster is a gear, 21 gears are arranged in total, the gears of the pulse clusters can be adjusted, the wavelength range of the pulse clusters is 580 nm-1200 nm, and the pulse width of the pulse cluster is shorter than the thermal relaxation time of the target tissue. The pulse has the beneficial effects that 21 gears are adjustable, the energy in the range not only ensures the effective treatment, but also gives consideration to the use safety of patients, is suitable for patients of different age groups, can meet the requirements of people with different skin types and different endurance capacities, wavelength suitable for human body absorption is reserved through light filtering, a plurality of pulses are arranged in each pulse cluster and can be adjusted, pulse width and pulse intervals can be adjusted and are not fixed, peak power of the pulses is adjustable, the pulse width is flexible and accords with the heat absorption effect of a focus, and comfort and safety are both considered while the treatment effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of meibomian gland dysfunction treatment, in particular to a pulse, modulation method and treatment method for meibomian gland dysfunction treatment. Background technique [0002] The meibomian glands, located in the middle layer of the eyelid, secrete a lipid substance that prevents tears from evaporating too quickly. Meibomian gland dysfunction (MGD) is a group of chronic and diffuse meibomian gland abnormalities, mainly manifested as terminal duct obstruction, qualitative or quantitative changes in lipids, etc., eventually causing changes in tear film stability, resulting in ocular inflammation, Ocular surface cell damage and irritation discomfort, severe cases may affect corneal damage. Meibomian gland dysfunction is the main cause of evaporative dry eye. With the increase in the use of electronic products, the increase in myopia and cataract surgery, and the aging population, the prevalence of dry eye...

AI Technical Summary

Problems solved by technology

However, the number of pulses of this light pulse dry eye treatment instrument is relatively small, and the energy is relatively large, mainly concentrated in the epidermis, and the energy that penetrates into the deep meibomian glands is less, or the epidermis absorbs too much energy after penetrating into the meibomian glands causing discomfort or even a risk of burns to the patient
