Appl. No.:

16/172519

Inventors:

- Vancouver, CA
Stephanie Lei-Ching Lin - Brooklyn NY, US

Assignee:

1039578 B.C. Ltd. - Vancouver

International Classification:

A61F 9/00
A61F 9/008

Abstract:

An applicator for applying fluid medicaments to a corneal surface of a patient, after surgery, includes a circular, ring-shaped member. The ring member creates an aperture which extends between parallel planes, with a wall surrounding the aperture as well as upper and lower openings into the aperture. The wall around the aperture is tapered, and there is a hole that extends through the wall. A hollow shaft is connected in fluid communication with the hole in the wall through which a fluid can be injected into the aperture. A bubble of the fluid can then be cradled in the aperture by the wall, and held therein by surface tension across the lower opening of the aperture.An application of the fluid bubble onto the patient's eye requires only contact between the fluid bubble and the eye, with no need for contact between the applicator and the eye.
