The present disclosure describes an optical probe for applying a laser light to at least the flat portion of the ciliary body and optionally other areas, such as the trabecular mesh, the ciliary crown and / or the ciliary sulcus of the eye, the present invention relates to methods, such as for treating glaucoma, reducing intraocular pressure (IOP), improving the outflow of aqueous humor from the eye, and / or reducing the accumulation of aqueous humor within the eye. The optical probe may be adapted for simultaneous treatment of a plurality of different regions, tissues, or eye bodies of the eye, or for sequential treatment of a plurality of different regions, tissues, or eye bodies of the eye.

The utility model provides a lens capsular bag anchoring device. The lens capsular bag anchoring device comprises an anchoring body and an anchoring arm. The anchoring body is in an M shape, the two anchoring arms are connected to the two opposite ends of the anchoring body respectively, and fixing rings are arranged at the ends, away from the anchoring body, of the anchoring arms. In the operation process, a suture is used for knotting at the V-shaped tip end of the anchoring body, and the other end of the suture penetrates out of the sclera of the ciliary sulcus and is knotted outside the eye to be fixed between sclera layers. The middle V-shaped portion of the anchoring body is arranged in front of an anterior capsule, the two protrusions at the upper end of the M shape pull the edge of an anterior capsule ring, the anchoring arm is implanted into a capsule bag, the equator of the capsule bag is jacked, pressed and pulled, the crystal capsule bag is made to restore the shape, and when an operation is finished, the anchoring arm can be permanently fixed to the sclera, and the IOL and the capsule bag are prevented from deviating together. Secondly, for a patient with dislocation of the IOL-capsular complex, the IOL-capsular complex can be pulled to the normal position through the anchoring device and fixed to the sclera.

The utility model provides an ophthalmologic operation needle which comprises a needle body, and a needle tip is arranged at one end of the needle body. A needle hole is formed in the needle tip and penetrates through the needle body in the length direction of the needle body, and the diameter of the needle hole ranges from 0.01 mm to 0.08 mm. According to the ophthalmologic operation needle, the central needle hole is formed in the needle point, and a 10-0 or 8-0 polypropylene suture can penetrate through the needle hole in the diameter range, so that after the needle point penetrates into an eye, the suture can penetrate through an IOL bag to be knotted and fixed with an IOL loop, and the long needle can exit in situ without penetrating through the eyeball wall on the other side. For a patient with IOL deviation, IOL bag complex deviation or only need to perform IOL unilateral loop ciliary sulcus fixation, a needle hole is formed in the tip end of the long needle, and after threading, the IOL is introduced into the eye through a needle tip. According to the three-piece type IOL, a suture line can be knotted and fixed to an IOL loop, and a long needle retreats along the original path. For a one-piece IOL, a long needle with an 8-0 suture can penetrate through the loop of the IOL, the polypropylene suture is left on the loop of the IOL, and the broken end is subjected to electrocoagulation knotting, so that operation steps are reduced, and wounds are reduced.

A lens for use in an intraocular lens system for treating age-related macular degeneration (AMD), the lens including an anterior surface, a posterior surface, and a plurality of haptics configured to align the anterior light-converging intraocular lens with an optical axis of the eye. The plurality of haptics may have a symmetrical design and comprising ciliary-sulcus-engaging surfaces configure to position the lens within in a ciliary sulcus of an eye. At least one of the anterior surface and the posterior surface may be rendered as aspherical surfaces selected to induce spherical aberration while minimizing optical aberration and thereby provide for a continuum of retinal images to be focused at an area macula of a retina of the eye between two retinal eccentricities.

An artificial lens capsule is provided for use during cataract surgery or in cases of aphakia (absence of lens) or posterior capsule rupture (PCR). A common complication during cataract surgery is the rupture of the posterior capsule, preventing the placement of a monofocal intraocular lens in the lens capsule due to inadequate support. Typically, a 3-piece, long haptic intraocular lens can be placed in the ciliary sulcus or capsule if the monofocal intraocular lens is sufficient. However, for placing a toric (astigmatism correcting) or presbyopia-correcting intraocular lens (multifocal), there are currently no options for a 3-piece sulcus-fixated lens. The artificial capsule disclosed herein can be inserted and supported by the anterior capsular rim or sutured into the sclera if capsular support is inadequate. This provides a stable region for placing a single-piece toric or presbyopia-correcting intraocular lens, thereby enhancing the options for lens placement in cases of inadequate capsular support. The device can also be a reservoir for other future intraocular and / or drug-eluting devices.

The present application relates to a kind of intelligent auxiliary prescription systems of lens eye intraocular lens, comprising: haptics landing line acquisition module, obtain the three-dimensional structure data of anterior chamber and posterior chamber, construct 3D topographic map of ciliary sulcus area by AI three-dimensional image semantics analysis, obtain the best fitting ciliary sulcus line by fitting, with the best fitting ciliary sulcus line as reference, calculate and obtain haptics landing line;Ideal haptics determination module, according to the lateral depth difference between each point on haptics landing line, obtain the ideal haptics position combination sequence of intraocular lens;Crystal matching module, obtain the inventory data of crystal, based on the arch height prediction range and ideal haptics position combination sequence obtained in advance, obtain the best matching intraocular lens and its implant rotation position scheme from the crystal inventory.Compared with prior art, the present application has the advantages of high accuracy of crystal size matching, meeting the stability requirements of crystal implantation, more accurately guiding how to rotate and adjust arch height of crystal and optimizing crystal prescription process.
