Abstract
The invention discloses an artificial lens with an iris diaphragm, comprising an optical zone (1) which is transparent at the center, the iris diaphragm (2) surrounding the optical zone (1) and a loop (3); the artificial lens is in an integrated style and is composed of an entire block of material, the material is selected from foldable materials such as hydrophobic acrylic ester, hydrophilic acrylic ester, silica gel, etc. The artificial lens with the iris diaphragm of the invention has soft texture, can be filled or implanted in the eyes by a small incision after being folded; in addition, the artificial lens has high refractive index, thin lens, small incision and slow formation of after cataract and can slowly restore in 2-30 seconds after being implanted, thus cyst membrane is not easy to be damaged; moreover, the artificial lens has the advantages of little astigmia developed in post-operation, quick healing, fast recovery of visual performance and little postoperative treatment; a brown iris, which is the natural color iris of Chinese, can be adopted, and the eye implanted with such an artificial lens looks more natural.
Description
Technical field
The invention belongs to a kind of ophthalmic medical articles for use, relate in particular to a kind of band iris diaphragm intraocular lens.
Background technology
The reason of coloboma of iris or aniridia mainly contains congenital and wound two class factors, mainly shows as to suffer from the eye photophobia, and especially traumatic simple eye aniridia patient, symptom is more obvious.In addition pupil excessive or not fenestra influenced the attractive in appearance of patient.The clinical corneal contact lens that once adopted is corrected, but this method is loaded down with trivial details, especially is not suitable for child and old people and uses.For the aniridia due to wound or factor such as congenital, the patient of pupil diameter＞8mm and coloboma of iris scope＞120 °, the rigid intraocular lens of posterior chamber type band black iris diaphragm who mainly selects for use at present German Morcher company to produce, can be divided into 67A, 67B, 67C, 67D, 67E, 6 types of 67G, China uses the 67G type more at present, its basic parameter is: total length 12.5mm, body 10mm, biconvex, optic diameter 5mm wherein, be ordinary PMMA, peripheral 2.5mm is wide to be the PMMA iridial part of retina of black, optic and iridial part of retina interconnect, and the button loop material also is the PMMA of black, and being two has the fixedly C shape button loop of aperture of suture, A constant 118.1, design anterior chamber depth 4.9.
The rigid intraocular lens's of band black iris diaphragm implantation step comprises: do limbus of corneae tunnel type otch, inject visco-elastic material in the anterior chamber, cut-out of limbus corneae is extended to chord length 10mm, the intraocular lens is implanted in the ciliary groove.Complete aniridia person is fixed fixedly person of need pedestrian worker crystalline lens suture, little scleral flap is done at 1.0～1.2mm place respectively outside 4 o'clock of sclera and 10 o'clock orientation, limbus of corneae, get band polypropylene line length pin, under the scleral flap in 10 o'clock orientation, along slightly being parallel to the oblique inserting needle of iris face, by homonymy sclera, homonymy ciliary groove, lesser ring of Merkel, offside ciliary groove, to the offside scleral flap, go out pin successively.Do limbus of corneae tunnel type otch, in the anterior chamber, inject visco-elastic material, press from both sides out polypropylene line ophthalmic section, cut off, respectively two broken ends of fractured bone are fixed on the aperture of intraocular lens's button loop from the centre with tweezers.Enlarge cut-out of limbus corneae to chord length 10mm, the intraocular lens is implanted in the ciliary groove, and tension polypropylene line two outer ends, bury under scleral flap respectively in scleral surface knotting, fixing, and with toe-in, use the 10-0 nylon suture to sew up cut-out of limbus corneae.
The rigid intraocular lens's of band black iris diaphragm shortcoming comprises: (1) body is big, material is crisp, easy fracture; (2) require otch big, about 10.0mm, the post-operative cornea astigmatism is serious; (3) band black iris diaphragm intraocular lens's optical surface and iris diaphragm diameter reach 10.0mm, if the forward and backward room of ophthalmic insufficient space, implantation process very easily damages cornea, back cyst membrane or vitreous body.This type of intraocular lens is not suitable for implanting congenital microphthalmus patient ophthalmic, this is because intraocular lens's optical surface and iris diaphragm diameter 10.0mm, its pair button loop vertex distance is 12.5mm, is microphthalmia if suffer from eye, and this intraocular lens will be difficult to be fixed on the tram within the eye.(4) optic PMMA and peripheral black PMMA iridial part of retina and non-Unitary, but link together, the adverse events that optic and iridial part of retina break away from found clinically.(5) postoperative complication appears easily: as anterior chamber's inflammatory reaction; Macula lutea generation capsule sample edema; Postoperative secondary glaucoma etc.(6) the original brown iris of black iris and Chinese does not match, and the eyes of implanting this intraocular lens seem blackening, differs too big with nature eye outward appearance.
For the bigger or complete aniridia person of coloboma of iris scope, at present except the rigid intraocular lens of implantation belt iris diaphragm, also comprise after little otch lens capsule bag is implanted into the fan-shaped artificial iris capsular tension ring of multi-disc and implant the foldable artificial crystalline lens, the post-operative cornea astigmatism degree is less relatively, but this operation still has indication narrow range, lens capsule bag to implant shortcomings such as the space is crowded relatively, black PMMA tension link easy fracture.
Summary of the invention
The objective of the invention is: a kind of band iris diaphragm intraocular lens is provided, and its matter is soft, and collapsible back is by little otch injection or implant ophthalmic, and the refractive index height, and crystal is thin, and otch is little, and the formation speed of a back barrier is lower simultaneously, is not easy to damage cyst membrane; The astigmatism that postoperative causes is few, and healing is rapid, and it is fast that visual function recovers, and post surgery treatment is few.
Technical scheme of the present invention is: a kind of band iris diaphragm intraocular lens, it is made up of the transparent optical zone of central authorities, the iris diaphragm that centers on described optical zone and button loop, described intraocular lens is an integral type, is made of a whole block material, and described material is selected from the foldability material.
Below technique scheme is further explained:
1. described material is hydrophobic acrylic acid's ester material.
2. described material is hydrophilic acrylate's material.
3. described material is a silica gel.
4. the transparent optical area diameter of described central authorities is 4-6mm, and described iris diaphragm width is 2-3mm.
5. the transparent optical area diameter of described central authorities is preferably 4.75mm, and described iris diaphragm width is preferred 2.6mm.
6. described intraocular lens's button loop is provided with two suture holes that are used for suture, and two suture holes are separately positioned on two buttons loop.
7. described suture bore dia is 0.4mm.
Peripheral iris every color be brown or black, preferably brown.
Band iris diaphragm intraocular lens of the present invention has overcome the rigid intraocular lens's of band black iris diaphragm shortcoming, and has the following advantages: (1) matter is soft, and collapsible back is injected by little otch or the implantation ophthalmic; (2) in a single day contact with corneal endothelium in operation, the damage of corneal endothelium is littler than rigid crystalline lens; (3) density is lower than rigid crystalline lens, so it is lighter; (4) refractive index height, crystal is thin, and otch is little, and the formation speed of a back barrier is lower simultaneously, implants the back and slowly recovers in second at 2-30, is not easy to damage cyst membrane; (5) astigmatism that causes of postoperative is few, healing rapidly, it is fast that visual function recovers, post surgery treatment is few.(6) brown iris is Chinese's true qualities irises, and the eyes of implanting this intraocular lens seem the comparison nature.
