Ophthalmic Dry Eye Diagnosis Equipment MDX DEA-100

Scope of application: This product is used for the treatment of dry eye patients mainly with meibomian gland dysfunction.Dry eye is a chronic ocular surface disease caused by multiple factors. It is caused by abnormalities in the quality, quantity, and dynamics of tears, leading to instability of the tear film or imbalance of the ocular microenvironment.

It is often accompanied by ocular inflammatory reactions, tissue damage, and neurological abnormalities, resulting in various discomfort symptoms and/or visual function disorders in the eyes. The core mechanism of dry eye is the high osmotic pressure of tears, which is also one of the characteristics of dry eye.

The high osmotic pressure of tears can directly or indirectly cause inflammation and damage to the ocular surface. The tear film is mainly composed of lipid layer, aqueous layer, and mucin layer.

Through tear dynamics (including blinking, etc.), tears are distributed on the ocular surface and finally expelled from the eye. Therefore, maintaining the stability of the tear film, preventing excessive evaporation of tears, and maintaining the fluidity of the ocular surface fluid are fundamental measures for dry eye treatment.

• The constant temperature fumigation therapy device has the following functions: constant temperature hot fumigation, constant temperature cold fumigation, and drug introduction.

• The temperature range for constant temperature cold fumigation is 7 ℃ to 15 ℃, with an error of ± 2 ℃.

• The constant temperature fumigation and drug conductivity temperature range from 40 ℃ to 44 ℃, with an error of ± 1 ℃.

• When the temperature of the spray port of the therapeutic apparatus exceeds 45 ℃ or is lower than 6 ℃, the therapeutic apparatus will have safety protection and prompt sound.

• The working time can be set in four time levels: 15 minutes, 20 minutes, 25 minutes, and 30 minutes, with an error of ± 30s.

• Anti dry burning protection function, when there is no liquid in the steaming pot, it cannot be heated; At the same time, when the nebulization box is short of water, the therapeutic device has an automatic shutdown function.

Mechanism of hot compress therapy:

      The function of dilating blood vessels, improving local blood circulation, promoting local metabolism, and facilitating the absorption of inflammation. Hot compress restores the fluidity of the increased viscosity of the eyelid ester, facilitating its excretion and improving or restoring the function of the meibomian gland. The conventional hot compress method uses local heating to restore the fluidity of the increased viscosity of the eyelid ester, which is beneficial for the discharge to improve or restore the function of the meibomian gland and treat meibomian gland dysfunction (MGD).

Mechanism of cold compress therapy:

There are receptors on the ocular surface that can sense cold stimuli, and dry eye patients may experience ocular surface damage and reduced corneal sensitivity, leading to a decrease in basal tear secretion and blink frequency. Cold compress can achieve local cooling, increase basal tear secretion, and thus improve dry eye symptoms.
