Description
Technical Field
The invention relates to the technical field of medical treatment, in particular to an integrated veterinary intraocular lens.
Background
The lens is arranged in front of the vitreous body, is connected with the ciliary body by the zonules of the lens, is in a biconvex lens shape and is rich in elasticity. The lens is a biconvex transparent tissue, which is fixedly suspended behind the iris in front of the vitreous body by zonules. The crystal is an important component of an eyeball curved light system and is the only refraction interstitium with the adjusting capacity, and the adjusting capacity of the crystal is gradually reduced along with the increase of the age to form the phenomenon of presbyopia. The curvature radius of the front part of the crystalline lens is 10mm, the curvature radius of the back part of the crystalline lens is about 6mm, the front and back diameters of the crystalline lens are 4-5mm, and the diameter of the crystalline lens is 9 mm;
the main components of human crystals are protein and water, which can cause fogging or clouding due to aging, and the fogging crystals can block light and images from being projected onto the retina. The phenomenon of crystal atomization can be caused by eye damage, certain diseases and even certain drug treatments; according to statistics, more than 90% of cataract cases are also caused by the essential aging process of human beings, namely, the eye crystals become turbid and then the vision is affected, the mechanism is not clear, and the drug treatment has not been developed in a breakthrough manner so far. The only truly effective treatment for cataracts is surgical treatment, which involves removing the lens that has become opaque and replacing it with an artificial lens, known as an intraocular lens. Intraocular lens implantation is the most effective means for treating cataract, and thousands of cataract patients obtain good vision through the safe and effective surgical method; according to the position of placement, the artificial lens is divided into an anterior chamber fixed type artificial lens, an iris fixed type artificial lens and a posterior chamber fixed type artificial lens. Generally, the optimum placement of the intraocular lens is within the capsular bag of the natural lens, i.e., the location of the posterior chamber-fixated intraocular lens.
Hard intraocular lenses and foldable intraocular lenses are classified according to hardness. The hard intraocular lens cannot be folded, and an incision (about 6 mm) with the same size as the optical part of the lens is needed to implant the lens into the eye. In order to adapt to the progress of the operation, the material of the artificial lens is gradually improved, the foldable artificial lens appears, the foldable artificial lens can be folded in half and even curled, the foldable artificial lens is implanted through an implantation forceps or an implantation device, and after the foldable artificial lens enters the eye, the foldable artificial lens can be automatically unfolded and supported at a designated position
The artificial lens is also called artificial lens, is a precise optical component which is implanted into eyes through operation to replace the removed self-turbid lens, and is equivalent to replacing a lens;
as with human, pets also experience lens aging with increasing age, and at present, special veterinary lenses are difficult to see in the market, and for this reason we propose a veterinary intraocular lens.
