Problems solved by technology

For a long time, the usual means of medical treatment or surgical treatment in clinical medicine, because they cannot restore the normal state of the tissue structure, the long-term effect is not ideal
The application of the applicant's previous patent application (application number: 2004100109388) has effectively improved the long-term therapeutic effect of glaucoma, but due to the two-layer thin ring sheet of the expansion ring The ring area on the inner side of the peripheral wall is larger. After being placed in the anterior chamber angle of the eye, the contact area between the two thin ring sheets and the cornea is larger. The corneal endothelial edema is likely to be caused by long-term friction of the cornea.

Embodiment Construction

[0010] The following embodiments in conjunction with the accompanying drawings will further illustrate the structure of the present invention.

[0011] refer to figure 1 , 2 , a dilating ring for treating glaucoma is a ring body with an outwardly opening annular groove (1) on the peripheral wall, and the outer edge of the side edge of the said annular groove (1) is in contact with the iris The diameter is larger than the diameter of the outer edge of the other side that is in contact with the cornea, and 10-15 radial through holes (2) are evenly distributed along the circumferential direction at the bottom of the annular groove (1).

[0012] The expansion ring can be made of elastic silicone gel, hydrogel or titanium alloy material.

[0013] refer to image 3 , using the expansion ring of the present invention to treat glaucoma, make a 3 mm long transverse tunnel-shaped incision on the cornea 6 at a point 1mm12 away from the edge of the cornea 6, and use a holder to send th...

Abstract

The expanding ring for treating glaucoma is one ring with annual outward opened notch in the peripheral wall and several radial through holes in the bottom of the annual notch. The expanding ring is set inside the iridocorneal angle so as to expand the closed or narrowed iridocorneal angle, to restore the normal state and function of the iridocorneal angle and to exhaust aqueous humor fluently. The expanding ring has excellent long term effect of treating glaucoma.

Description

technical field [0001] The invention belongs to ophthalmic medical equipment, in particular to an expansion ring specially used for treating glaucoma. Background technique [0002] Glaucoma is one of the common diseases in ophthalmology, and it is also the main cause of blindness. Patients often suffer from blindness due to progressive aggravation. For a long time, the usual means of drug therapy or surgical treatment in clinical medicine, because the normal state of the tissue structure cannot be restored, the long-term effect is not ideal. The application of the applicant's previous patent application (application number: 2004100109388) <Expansion ring dedicated to the treatment of glaucoma> has effectively improved the long-term therapeutic effect of glaucoma, but due to the two-layer thin ring sheet of the expansion ring The ring area on the inner side of the peripheral wall is relatively large. After being placed in the anterior chamber angle of the eye, the two-...
