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 [0001] The invention belongs to an ophthalmic medical product, in particular to an intraocular lens with an iris septum. Background technique [0002] The causes of iris defect or aniridia mainly include congenital and traumatic factors, mainly manifested as photophobia in the affected eye, especially in patients with traumatic monocular aniridia, the symptoms are more obvious. In addition, the pupil is too large or not round, which also affects the appearance of the patient. Clinically, contact lenses have been used for correction, but this method is cumbersome, especially not suitable for children and the elderly. For patients with aniridia, pupil diameter > 8 mm, and iris defect range > 120° caused by trauma or congenital factors, the posterior chamber hard intraocular lens with black iris septum produced by Morcher Company in Germany is mainly used, which can be divided into 67A, 67B, 67C, 67D, 67E, and 67G 6 types. At present, 67G type is mostly u...
