Many methods for such correction are available today, such as spectacles or contact lenses. However, correction with glasses cannot provide patients with optimal visual acuity, while correction with contact lenses is difficult for individuals to tolerate,9 especially for the elderly, while cataracts are the most commonly occurring. death,

た構造物は存在しない。One of the major problems in intraocular vision correction is the development of intraocular prosthetic lenses or lenticules suitable for implantation in both the anterior and posterior chambers of the eye. Today, there are no structures suitable for implantation within the anterior and posterior chambers of the eye without any pre- or post-operative complications.

補綴レンズを利用することが可能となる。On the other hand, the issue is of utmost importance. This is because the ability to provide a "universal" lenticule suitable for implantation in both the anterior and posterior chambers of the eye would improve the strategy chosen by the surgeon and reported by the physiological state of the eye to be operated on. Accordingly, the same model of prosthetic lens can be used to perform surgical procedures.

(980, Vol. 22, M4, p. 429). However, the intraocular lens implant has substantial drawbacks, namely, obstruction of structures due to the angle of the anterior ocular lens, causing ulcer formation at the angle of the anterior chamber and during prolonged post-operative treatment. There is the problem of the aforementioned complications that appear as.

（ソ連国発明証第８５８，８１９号）。One or more intraocular prosthetic lenses are known in modern ophthalmology, consisting of an optical lens body and three support members held therein, each of which has a fan-shaped shape. The remaining two members are located on the same side of the lens body which is diametrically opposed to the sector-shaped member (USSR Invention Certificate No. 858,819).

This lens includes an optical lens body and a three-dimensional lens held therein.
an intraocular prosthetic lens comprising two support members, one of the support members being loop-shaped, while the other two (rlA) members are held in the lens body on the ipsilateral side thereof,
two support members located on the same side of the lens body are shaped as two arcuate curved portions facing each other;
The space end portion of the portion is arranged symmetrically with respect to a plane passing through the midpoint between the lens body and the loop-shaped member, and the arcuate part is curved toward the back surface of the lens body.

As is clear from FIG. 1, the arcuate member 3 is located on the side of the lens body diametrically opposite to the loop-shaped member 4, and is further fixed to the lens body 2 at one of their two ends by known means. ing. The arcuate elements 3 are curved towards each other 9 and their spatial ends are arranged symmetrically with respect to a plane passing through the midpoint of the lens body 2 and the loop-shaped element 4. In addition, the arcuate member 3 is curved somewhat backwards towards the dorsal surface of the lens body and can be further quickly curved during surgery to adapt to the radius of curvature of the patient's capsular membrane. can.

平行になるように更に湾曲している。FIG. 3 is a side view of an intraocular lens substantially similar to the lens shown in FIGS. 1 and 2, which shows the end of the loop-shaped member 4' and the extreme end of the arcuate member 3'. The only difference is that the two separated ends are on the same virtual circumference having its center at the center of the lens body 2. As is clear from FIG. 3, the portion 5 of the arcuate member and the portion 6 of the loop-shaped portion, close to said end, are further curved parallel to the main surface of the lens body.

前眼房に持ってくる。While grasping the lens so that the loop-shaped member 4 faces upward, the intraocular lens is implanted using support piece forceps. The lower parts of the support members 3 are then placed in the direction of the anterior chamber, thus causing the lens to move further downwards, and the support members 4 are brought below the upper end of the capsular incision and then in the superior angle of the anterior chamber. Bring the active part of the forceps that grips the lens into the anterior chamber of the eye so that it is placed inside.

Regarding the pupil (4,5~5.Qnn) that is moderately dilated, the implanted lens is placed so that the loop-shaped support member faces downward.
On the other hand, grasp it using support piece forceps so that the arcuate member faces upward. The lens was then inserted into the anterior chamber using forceps so that the loop-shaped member passed through the pupil and under the inferior part of the cornea. The forceps carrying the lens are then moved downward so as to press the loop-shaped member onto the ciliary body a1, and then the forceps are removed. Furthermore, the operation is carried out using two micro-supporting pieces with rounded ends.
