Abstract
The utility model relates to an intraocular lens for the ophthalmology, in particular to a posterior chamber intraocular lens with sutures. The posterior chamber intraocular lens with the sutures comprises an intraocular lens optics portion and two intraocular lens loops connected with the intraocular lens optics portion. The tail portions of the intraocular lens loops are respectively provided with a threading hole, the polypropylene sutures penetrate into the threading holes, and the two ends of each polypropylene suture are provided with long straight needles respectively. According to the posterior chamber intraocular lens with the sutures, fixation of the ciliary groove sutures of the posterior chamber intraocular lens is more convenient and faster to operate; due to the facts that the polypropylene sutures penetrate into the tail portions of the intraocular lens loops and the two ends of each polypropylene suture are provided with the long straight needles respectively, the sutures and the intraocular lens loops do not need to be knotted in the operation process, the sutures do not get loose and fall after the operation, the intraocular lens does not move, the postoperation effect is good, and benefits are brought to patients.
Description
technical field
This utility model relates to the artificial intraocular lenses of ophthalmic, particularly a kind of posterior chamber intraocular lens that carries suture.
Background technology
In clinical ophthalmology work, for cyst membrane after the postoperative cyst membrane without issue of traumatic cataract, postcataract, break and cannot implant artificial intraocular lenses in pouch, need to be at ciliary groove implant intraocular lens.When fixing artificial intraocular lenses, conventional suture and artificial intraocular lenses's loop breaks into toe-in, sew up and be fixed on ciliary groove sclera again, but because suture is more sliding, the toe-in on suture and artificial intraocular lenses's loop usually easily gets loose after surgery, causes artificial intraocular lenses to be shifted, after some artificial intraocular lenses's displacement, even fall into vitreous chamber, usually need row operation for the second time to adjust position of intraocular lens, affect surgical effect, to patient, bring unnecessary misery.
Utility model content
The purpose of this utility model is to overcome existing deficiency in prior art, and a kind of posterior chamber intraocular lens that carries suture is provided, and to solve postoperative suture and artificial intraocular lenses's loop easily gets loose, causes the problem of crystal displacement.
In order to realize above-mentioned utility model object, this utility model provides following technical scheme:
A kind of posterior chamber intraocular lens that carries suture, comprise intraocular lens optic portion and two artificial intraocular lenses's loops that are connected with intraocular lens optic portion, the afterbody of described artificial intraocular lenses's loop is respectively provided with a through wires hole, in through wires hole, be installed with prolene suture, the two ends of described prolene suture are all with long staight needle.
In the above-mentioned posterior chamber intraocular lens that carries suture, the afterbody of described artificial intraocular lenses's loop is fusiformis, and afterbody central authorities have through wires hole.
In the above-mentioned posterior chamber intraocular lens that carries suture, described through wires hole is slotted eye.
compared with prior art, the beneficial effects of the utility model:this utility model is by posterior chamber intraocular lens ciliary groove suture fixation faster and more convenient operation, because the afterbody of artificial intraocular lenses's loop is installed with prolene suture, and the two ends of prolene suture are all with long staight needle, in operation process, suture and artificial intraocular lenses's loop are without tiing a knot again, postoperative suture can not get loose, artificial intraocular lenses can not be shifted, and postoperative effect is good, to patient, brings glad tidings.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of embodiment;
Labelling in figure: 1-intraocular lens optic portion, 2-artificial intraocular lenses loop, 3-through wires hole, 4-suture, the long staight needle of 5-.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
In order to make object, technical scheme and the advantage of utility model clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, and be not used in restriction this utility model.
embodiment 1
As shown in Figure 1, the present embodiment carries the posterior chamber intraocular lens of suture, comprise intraocular lens optic portion 1 and two artificial intraocular lenses's loops 2 that are connected with intraocular lens optic portion 1, the afterbody of described artificial intraocular lenses's loop 2 is respectively provided with a through wires hole 3, in through wires hole 3, be installed with prolene suture 4, the two ends of described prolene suture 4 are all with long staight needle 5.
The use procedure of the present embodiment:
(1) patient adopts 2% lignocaine and 0.75% bupivacaine mixed liquid to do retrobulbar nerve block anesthesia.
(2) limbus of corneae place, Rhizoma Atractylodis Macrocephalae eye top makes 5. 5～6. 0 mm fixation through scleral tunnels incisions, and anterior chamber injects viscoelastic agent, can locate to cut off conjunctiva at 1 and 7.As shown in Figure 2, two artificial intraocular lenses's loops 2 (being respectively artificial intraocular lenses's loop 2A, artificial intraocular lenses's loop 2B) that the present embodiment intraocular lens optic portion 1 connects, be connected to the top and bottom of intraocular lens optic portion 1, the afterbody of two artificial intraocular lenses's loops 2 is all installed with prolene suture 4(and is respectively prolene suture 4A, prolene suture 4B), the two ends of prolene suture 4 A are all respectively long staight needle 5A, long staight needle 5B with long staight needle 5().Particularly, during operation, prolene suture 4A through artificial intraocular lenses's loop 2A, the two ends of this prolene suture 4A are respectively with long staight needle 5 (long staight needle 5A, long staight needle 5B), the long staight needle 5A that left end is wherein connected is through otch, through under anterior chamber, lesser ring of Merkel and iris, from the scleral surface elongation Gong Yuan 1mm of 7 positions, pass, other one piece long staight needle 5B same method passes from sclera, import artificial intraocular lenses to ciliary groove, tighten up suture, knotting, toe-in is imbedded in sclera, adjusted crystal positions.
(3) pass the prolene suture 4B of artificial intraocular lenses's loop 2B, the two ends of this prolene suture 4B are respectively with long staight needle 5 (long staight needle 5C, long staight needle 5D), operation process in same step (2) is similar, long staight needle 5 passes from the scleral surface elongation Gong Yuan 1mm of 1 position, the same fixing suspention of method line, artificial intraocular lenses's suspension completes, and finally injects Carbachol miotic, make pupil retraction 3～4mm size, suction displacement anterior chamber adhered elastomer after pupil fourth contact.
