Problems solved by technology

[0004] However, the fixed traction strap needs to be stitched and knotted by hand, and it is difficult to precisely control the pressure and height of the top during the stitching process
Therefore, although it is possible to press and reinforce the posterior sclera, it is still unable to accurately correct the patient's eye axis and accurately change the patient's diopter.

Abstract

The invention provides a posterior scleral staphyloma stent which comprises at least one arc-shaped arm, at least one fixing area and at least one adjustable jacking structure; each arc-shaped arm corresponds to one fixing area and one adjustable jacking structure, and the two ends of each arc-shaped arm are connected with the corresponding fixing area and the corresponding adjustable jacking structure respectively. The posterior scleral staphyloma stent has the advantages that the jacking height of the posterior sclera can be repeatedly and accurately adjusted according to an intraoperative optometry result, the macular region of the retina of a patient is directly jacked to a parallel light focus point, and the problem of ametropia of the patient is corrected while the posterior scleralstaphyloma is treated.

Description

technical field [0001] The invention relates to the technical field of devices used in eye surgery, in particular to a posterior staphyloma support. Background technique [0002] In high myopia, especially pathological myopia, in addition to elongated eye axis, posterior staphyloma may also appear. The reason is that the resistance of the sclera is weakened due to congenital defects or pathological damage. Under normal intraocular pressure or high intraocular pressure, the sclera and uvea bulge outward. Posterior staphyloma may also be accompanied by progressive myopia deepening in adulthood, retinal choroidal atrophy, macular hole, macular retinoschisis, retinal detachment and other pathological manifestations that seriously affect vision. [0003] In the prior art, the posterior sclera reinforcement operation can be used for the treatment of posterior staphyloma, that is, the sclera at the posterior pole of the eyeball is reinforced by pressing materials (allogeneic or au...
