Detailed Description

An embodiment of a non-contact orthokeratology device of the present invention is further described with reference to fig. 1.

A non-contact cornea shaping device is composed of two semi-soft elastic sheets 1, two buffer sheets 2, a sliding buckle 3 and a connecting belt 4, wherein the curvatures of the inner side surfaces of the two elastic sheets 1 are far smaller than the curvatures of the front surfaces of corresponding eyeballs, and the curvatures of the inner side surfaces of the elastic sheets 1 are increased along with the increase of pressure applied to the elastic sheets 1, so that the pressure is formed on the diagonal membrane through an eyelid. Aiming at objects with different eye distances, the fastener on the semi-soft connecting belt 4 can be slid to drive the buffer sheet 2 and the elastic sheet 1 to slide simultaneously until the elastic sheet 1 is just opposite to the eyeball of the wearing object. Since the eye socket depth of different wearing objects is different, the elastic sheet 1 may not be in contact with the eyeball of the wearing object, and the thickness of the buffer sheet 2 can be increased or reduced until the elastic sheet 1 is in firm contact with the eyeball. The elastic sheet 1, the buffer sheet 2, the connecting belt 4, the sliding buckle 3 and the like are all wrapped on the binding belt 50, and a zipper is arranged at the central axis position inside the binding belt 50, so that the left and right positions and the front and back positions of the elastic sheet 1 can be opened and adjusted at any time. The binding band 50 is provided with an elastic band 51 at the middle part, the back part of the elastic band 51 is connected with a nylon hasp 52, and the nylon hasp 52 passes through a hasp ring 53 to form a reciprocating motion and can be fixed on a certain size so as to adapt to wearers with different head circumference. When the elastic piece is worn by a wearer, the curvature of the cornea of the eyeball does not need to be measured by an eyeball curvature measuring instrument, the wearer wears the elastic piece in advance according to the comfort degree of the wearer, the vision level is recorded before wearing the elastic piece, the vision level is measured again after wearing the elastic piece for one night, then the next night wearing is determined according to the vision improvement degree, the pressure is increased or reduced (namely, the curvature of the elastic piece 1 is correspondingly increased or reduced), when the vision is not improved much after wearing the elastic piece for the first night, the pressure is increased at the next night, after the elastic piece is adapted for a plurality of days, the wearer basically can master the proper pressure, the corresponding vision improvement level is obtained, and the wearer continuously wears the elastic piece under the pressure. With the change of the corneal curvature, after the vision of the wearer is continuously improved, the wearer can continuously adjust the pressure by himself or herself, and the pressure is slowly reduced. When the integrated external corneal reshaping device is worn for a long time, the curvature of eyeballs can be slowly changed, and the device has positive significance for correcting the corneal curvature of pseudomyopia patients and primary and secondary school students in the growth and development stage, and has the opportunity of curing the pseudomyopia.
