Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 to Figure 2 Top and cross-sectional views of the shaped scleral lens shown. Please also refer to figure 1 and figure 2 , as shown in the figure, a special-shaped scleral mirror, the special-shaped scleral mirror includes an optical zone 1 and a plurality of stabilizing wings 2 radially extending from the optical zone 1, the edges of the stabilizing wings 2 are arc-shaped and connected to Together form edge arc 3.

[0021] In the embodiment of the present invention, the above-mentioned stabilizing wings 2 are preferably three, and are equilaterally arranged. However, the present invention is not limited thereto, and those skilled in the art can set the above-mentioned stabilizers 2 as unequal sides as required, and the number can also be adjusted adaptively.

[0022] When the special-shaped scleral len...

Abstract

The invention discloses a special-shaped sclera lens. The special-shaped sclera lens comprises an optical area and a plurality of stabilizing wings which extend radially outwards from the optical area; the edges of the stabilizing wings are arc-shaped and are connected together to form edge arcs. According to the special-shaped sclera lens disclosed by the invention, the full contact between a lens and a sclera is changed into three-point stable contact, so that the pressure or the adsorption force of the lens on the sclera is greatly reduced, and the lens has enough motion degree during a blinking process. A clearance is reserved among the points of the lens, so that tear exchange is completed during the motion process of the lens, and the health of cornea is kept to the great possible; meanwhile, the eyesight of patients with irregular corneas can be corrected or improved, so that the patients can obtain the capacity of returning to work and living autonomously.

Description

technical field [0001] The invention relates to a scleral lens in the profession of ophthalmology and optometry, in particular to a special-shaped scleral lens. Background technique [0002] In the field of optometry, people who often encounter irregular corneas need to correct or improve their vision. In the face of the needs of these people, the currently available methods are to use soft, rigid or combination of soft and rigid contact lenses or scleral lenses to solve. But the problem is that during the application of soft or combination of soft and hard contact lenses, the safety of the cornea has certain risks due to less lens mobility, poor tear exchange, and contact between the lens and the cornea. The application of scleral lenses is also difficult to fit because of very little tear exchange, and excessive pressure or adsorption on the sclera, and it is difficult for the wearer to wear them continuously for a long time. Moreover, the part outside the limbus of the ...
