Description

Special cornea protector for upper eyelid ptosis correction

Technical Field

The utility model relates to the technical field of cornea protectors, in particular to a cornea protector special for upper eyelid ptosis correction.

Background

In life, the transparent part of the outer layer front part of the eyeball wall. Is circular, occupies one sixth of the outer layer area, is about 1 mm thick, and is mainly composed of avascular connective tissue. The front part slightly protrudes and is bent like a sphere, and has a refraction effect. The cornea contains abundant sensory nerve endings, and any minor irritation, injury or inflammation can cause pain and tear. If the cornea is tapped with cotton, a protective response of eyelid closure, known as corneal reflection, is caused. The junction of the cornea and sclera is called the limbus. The blood vessels of the limbus and the aqueous humor in the eyeball supply corneal nutrition. The curvature of the normal cornea is uniform for each radial line and therefore the refractive index is the same. If the curvature is not uniform, refractive anomalies, known as astigmatism, are caused.

The protection device is needed to be used for cornea after the ptosis correction operation, so that the cornea is prevented from being recovered after the operation under the influence of strong light stimulation, and the cornea protection lens is generally used for cornea protection in the traditional manner, so that the strong light stimulation can be reduced, and the effective protection can be provided.

As disclosed in chinese patent No. CN201310593512.9, the disposable cornea protective lens for ophthalmic surgery comprises a smooth lens surface and a lens inner surface, wherein the lens surface and the lens inner surface are integrally connected to form an arc-shaped lens body, and a cotton sheet for blocking light from entering the pupil is wrapped in an interlayer between the lens surface and the lens inner surface; the disposable cornea protecting lens for the ophthalmic surgery, disclosed by the utility model, is safe and sanitary and has an obvious effect by shading by utilizing the cotton sheets in the lens, and can reduce the stimulation of an operative light source to a patient; the arc lens is similar to the shape of human eye mask, and can be stably attached to cornea.

However, the cornea protective lens is inconvenient to damage and replace when being used for a long time, thereby bringing inconvenience to people.
