Abstract
The invention discloses a novel rigid gas permeable cornea contact lens, comprising a peripheral arc of the lens. The lens is characterized in that the inner rim of the peripheral arc of the contact lens is provided with two symmetric stable pterions or three stable pterions, wherein the distance of inner top end and outer top end of the stable pterion is between 0.2 and 7mm; the inside arc surface of the stable pterion can be a conical arc with an arch bottom angle of between 20 and 40 degrees; the inside arc surface of the stable pterion can be a spherical arc with the radius of curvature of between 6 and 25mm; the inside arc surface of the stable pterion can be a non-spherical arc, the difference of curvature radiuses of the starting point and the finishing point of the non-spherical arc is between 0 and 1mm, and the curvature radius of the starting/finishing point is between 6 and 25mm; and the inside arc of the stable pterion can be single arc or multi-arc which is a single multi-arc or combined multi-arc of the conical arc, the spherical arc or the non-spherical arc. The structure of the lens improves the stability and the centralization of various lenses in cornea, so that various cornea contact lenses can achieve the state that the comfort state is more comfortable, and the eyesight is more perfect.

Hard corneal contact lens is compared with soft contact lens, has both improved oxygen permeability, guarantees the fastness of material again, and has good wettability and resistance to settling.It has stood domestic and international ophthalmologist, oculist clinical verification for many years to control, the corrective therapy effect of juvenile true myopia and keratoconus, and has obtained certainly.At present, hard corneal contact lens only places the conjunctiva chamber of canthus limbus of sclera scope usually, directly is close to lower tarsal conjunctiva and cornea, because there is the desirable not to the utmost situation in the location of various hard corneal contact lenses on cornea in the scrambling of people's cornea.
Summary of the invention
The objective of the invention is at the problems referred to above, propose a kind of novel rigid air-permeable cornea contact lens, changed the location of various hard corneal contact lenses on cornea ideal situation not to the utmost, strengthened stability and the placed in the middle disposition of various eyeglasses at cornea.
Technical scheme of the present invention is:
A kind of novel rigid air-permeable cornea contact lens comprises the circumference arc district of eyeglass, and it is characterized in that: the inward flange in the circumference arc district of described novel rigid contact lens is provided with stable pterion or three stable pterions of two symmetries; The interior outer end of described stable pterion end apart from 0.2-7mm; The inboard cambered surface of the concave surface of described stabilizer is conical surface arc, spherical arc or aspheric surface arc.
Described three stable pterions equidistantly or not are equally spaced along the inward flange in circumference arc district; Described each stable pterion is the 1/6-1/3 of inward flange.
The inboard cambered surface of described stabilizer is that the base angle of conical surface arc is 20 °-40 °.
The inboard cambered surface of described stabilizer is a spherical arc, radius-of-curvature 6-25mm.
The inboard cambered surface of described stabilizer is the aspheric surface arc, and the absolute difference of the radius-of-curvature of aspheric surface arc starting point and terminal point is 0-1mm, starting point radius-of-curvature 6-25mm, terminal point radius-of-curvature 6-25mm.
The inboard cambered surface of described stabilizer is single arc or multi sphere, and described multi sphere is the single multi sphere or the combination multi sphere of conical surface arc, spherical arc or aspheric surface arc.
Described stabilizer is arc, trapezoidal or rectangle.
Described stabilizer utilizes mode bonding or cutting to connect.
Described eyeglass kind is used eyeglass after comprising hard corneal contact lens, Ortho-K, keratoconus eyeglass, scleroscope and operation on cornea.
The arc district, neighboring of described stabilizer is curved in fillet and the convex surface.
Beneficial effect of the present invention:
The present invention is using behind hard corneal contact lens, Ortho-K, keratoconus eyeglass, scleroscope and the operation on cornea on the corresponding edge of eyeglass, make the arc of two symmetries, trapezoidal or rectangular curved surface, changed because the scrambling of people's cornea, cause the desirable not to the utmost situation in the location of various hard corneal contact lenses on cornea, this curved surface has increased stability and the placed in the middle disposition of various eyeglasses at cornea, allow the join suitable state of various contact lenss on cornea reach betterly, eyesight also reaches optimal state.
