  • Treatment with tear plugs/lacrimal plug closure

    Since most tears leave the eye through the tear ducts to the nose except for evaporation from the surface of the eye, this method closes the tear ducts to reduce tear outflow and to allow sufficient tears to accumulate on the surface of the eye. We use two types of plugs in our clinic.

    Superflex Plug
    (1)Superflex Plug

    superflex plug is a good reviews product that is superior in better fit, more retainability and grater patient comfort. It has a wide range (0.4mm to~1.1mm) so it is comfortable with various lacrimal point size of each patient.
    Medical device approval number: 21200ZY00283000


    They are punctal plugs which are made from biocompatible material, atelocollagen. They are liquid at first, but it solidifies due to body temperature. Since they are liquid, they are easy to fill the tear block, but once they change into gel, it blocks your tear duct with less irritation. *The major component is water soluble collagen. It will eventually melt into your body.

    Punctal Plug F
    (3)Punctal Plug F

    The head of plug is designed to be hypodermic shape so that it makes easier for doctors to insert an object without measuring a size of lacrimal punctum. Besides, the plug is preliminarily set at an inserter in order to make it easier to put an inset in lacrimal point and reduce a possible risk of being buried.

  • Warm compress (Eye Hot)

    Warm compress (Eye Hot)

    Eye Hot emits red light and heat to help the meibomian glands produce oil. This will help reduce eye strain. The 0.7-micron wavelength light emitted by Eye Hot penetrates the skin more quickly than near infrared rays, warming the eyelids quickly.

  • Ophthalmic needle

    Ophthalmic needle

    This is the needle used during the tear flow test. It is suitable for inserting at the entrance of the tear duct and cleaning.
