Description
Technical field
This utility model relates to an optometry technical field, particularly relates to eyeglass in a kind of cornea.
Background technology
Keratoconus is that one is characterized with keratectasia, causes Central corneal portion forwardly convex in conical and generation height
Spend irregular myopic astigmatism and the constitutional corneal degeneration disease of different inpairment of vision.The easy blinding of this ophthalmic diseases, and morbidity
Rate is higher；There will be acute corneal edema late period, form cicatrix or perforation of cornea, vision is badly damaged.
There are three kinds of Therapeutic Method at present: the first is to wear RGP glasses；The second is corneal cross-linking art；The third is angle
Film transplantation.But these three Therapeutic Method is all difficult to reach to make the degree of patient satisfaction from principle.Control for existing these three
Treatment method, treatment costly, and it also requires long-term Drug therapy；The most still do not reach preferably
Curative effect, the vision of patient can not get improving.
Treatment is so that keratoconus obtains good curative effect with the following method: first doing a thickness with femtosecond laser is
The cornea flap of 150 microns, does not do trimming, and the base of a fruit of cornea flap is positioned at the offside of cone, and a length of 2 millimeters of the base of a fruit, width is 5 millimeters；
Then with iris repositor, inter-lamination of cornea is separated, and by eyeglass implant angle film interlayer in cornea；Finally adjust lens position, depending on
Situation closes cornea base of a fruit wound.But the eyeglass not matched with this new technique on market so that the person that has keratoconus without
Method makes to correct in this way.
To sum up, how producing the eyeglass matched with this technology is that those skilled in the art's technology urgently to be resolved hurrily is asked
Topic.
