Description
Technical field
This utility model is about the soft artificial intraocular lenses's device of a kind of improved single type, this device can improve the stability of artificial intraocular lenses in capsule, reduce the probability of back capsule muddiness, reduce artificial intraocular lenses's adherent probability between loop and the optics in folding implantation process.
Background technology
The artificial intraocular lenses is a kind of artificial lens that can implant ophthalmic, is used for replacing the mineral crystal that becomes the human eye of muddiness because of the cataract disease, perhaps is used for refractive surgery to correct the vision of human eye.Artificial intraocular lenses's form normally is made up of the support loop of a circular optics and periphery.Optics is to be made by transparent macromolecular material.These macromolecular materials can be hard, also can be soft.Artificial intraocular lenses by hard material is made must could implant ophthalmic by a bigger otch (usually greater than 6 millimeters), so be eliminated substantially in developed country.Artificial intraocular lenses by soft material is made also often is known as collapsible artificial intraocular lenses, can implant ophthalmic by a less otch (from less than 2 millimeters to 3 millimeters) in folding or the back of curling.The flexible material that is used to prepare collapsible artificial intraocular lenses at present mainly is divided into silica gel, several classes such as hydrophilic acrylate's (hydrogel) and hydrophobic acrylic acid's ester.
Press the combination of optics and support loop, soft collapsible artificial intraocular lenses is divided into three-member type and single type usually.For example United States Patent (USP) 5,118, and 452 provide a kind of three-member type artificial intraocular lenses's device, are made up of optics and two the support loops of being made by flexible material of being made by hard material.Three-member type artificial intraocular lenses's processing relative complex is because need be inserted into additional process in the optics supporting loop.And the support loop of being made by hard thermoplastic (such as methyl methacrylate) stress relaxation phenomenon can occur in the life-time service process.In addition, this hard support loop is folding or bending easily in the operation implantation process, can bring difficulty and bring injury to patient's eyes to operation.The soft collapsible artificial intraocular lenses of single type, its optics and support loop are an integral body, are made by same flexible material.The soft collapsible artificial intraocular lenses of early stage single type such as United States Patent (USP) 4,664,666, adopts board-like design, is also referred to as closed support loop design.This board-like design has increased artificial intraocular lenses's cumulative volume, is unfavorable for little otch implant surgery.And the soft collapsible artificial intraocular lenses of up-to-date single type such as United States Patent (USP) 5,716,403, adopts open support loop design.This design is easy to processing and operation is implanted.
But the single type artificial intraocular lenses of the open support loop design of this employing, the active force between its support loop and the capsule is far below three-member type artificial intraocular lenses and board-like artificial intraocular lenses.If the active force that supports between loop and the capsule is low excessively, phenomenons such as the artificial intraocular lenses may rotate within the eye, is offset, inclination influence patient's vision.Some adopts the single type artificial intraocular lenses of open support loop design, such as United States Patent (USP) 5,716,403, supporting even place of loop and optics, adopted the hinge type design, when being subjected to bag pressure and contracting, artificial intraocular lenses's optics can not protrude to the anterior chamber with expectation artificial intraocular lenses's support loop.But, this articulated junction, thickness and width are all little than the neighboring area, have therefore reduced the active force that supports between loop and the capsule more.
Tool is in folding implantation process with the single type artificial intraocular lenses's of open support loop another one problem, and supporting loop may stick on the optics, and can not in time open, even can not open automatically forever, has greatly increased the complexity of operation.
Back capsule muddiness is also referred to as the secondary cataract, is that the artificial intraocular lenses implants a kind of common complication in back.Back capsule muddiness is because cause between the capsule residual lens epithelial cell proliferation is moved to the artificial intraocular lenses behind the cataract operation rear surface and back.Optics the artificial intraocular lenses adopts the sharp right edge, as United States Patent (USP) 6,162,249 and 6,468,306, be proved to be a kind of method that can effectively reduce back capsule muddiness because this design can stop the lens epithelial cell migration between artificial intraocular lenses's the rear surface and back capsule (referring to people's such as Buehl article, Journal ofCataract and Refractive Surgery, 34 volumes, the 1976-1985 page or leaf).This optics with sharp right edge is realized than being easier on the three-member type artificial intraocular lenses, because it is very thin to support loop, and is inserted on the optics.Realize relatively difficulty of sharp right edge on the single type artificial intraocular lenses, because it supports loop and optics is connected as a single entity, and because the support loop is that soft material is made, the broad that need do is thicker.Realize the sharp right edge on the single type artificial intraocular lenses, the edge of optics is thick, and supporting loop will approach, and perhaps square edge step drop is little.If the edge of optics is too thick, can increase artificial intraocular lenses's cumulative volume, strengthen the difficulty of small incision surgery; If it is too thin to support loop, the active force between it and the capsule is not enough, and the artificial intraocular lenses can be built on the sand in capsule; If square edge step drop is too little, the migration that stops the lens epithelial cell is not had effect.
Therefore, a kind of good artificial intraocular lenses's device needs to guarantee the stability of artificial intraocular lenses in capsule, reduces the probability of back capsule muddiness, guarantees that the artificial intraocular lenses can in time open after implanting eyes, can not support the phenomenon that loop and optics bond together.
