Problems solved by technology

(2) Severe post-developmental disorder occurs
(4) Difficulty in preoperative biometric measurement leads to uncertainty in diopter calculation, making it difficult to achieve the ideal diopter
The refractive results of this treatment method are often unsatisfactory, and there are still fibrosis and recurrent disorders caused by the severe postoperative inflammatory response.
It also makes surgery difficult for the replacement intraocular lens that needs to be replaced, and increases the risk of capsular bag damage

Abstract

The invention mainly relates to the technical field of ophthalmic intraocular lenses, in particular to a comprehensive intraocular lens implant for congenital cataract. The comprehensive intraocular lens implant comprises an adjustable intracapsular ring and a common intraocular lens assembled on the adjustable intracapsular ring, the adjustable intracapsular ring comprises an annular body and a boss used for assembling an intraocular lens, the boss is arranged on the inner side face of the annular body, and the annular body is of a closed-loop structure or a C-shaped open-loop structure. Theadjustable intracapsular ring is specially designed and has certain thickness, shape and elasticity, the outline and elasticity of the infant capsular bag after the natural crystalline lens is removedcan be kept, and capsular bag contraction caused by no natural crystalline lens is prevented. The intracapsular ring not only can generate corresponding size change along with the growth of the infant capsular bag to prevent migration of epithelial cells, but also can be used for fixing an intraocular lens implanted in the later period, and convenience is provided for secondary implantation of the intraocular lens in the capsular bag.

Description

technical field [0001] The invention mainly relates to the technical field of ophthalmic intraocular lens, and more specifically relates to a comprehensive intraocular lens implant for congenital cataract. Background technique [0002] The most basic function of the human eye is to transmit light through the cornea, the most transparent refraction part in the front of the eye, and then gather it on the retina after being imaged by the natural lens to achieve visual function. The quality of the focused image depends on many factors, including the size and shape of the eye and the transparency of the cornea and natural lens. Aging, heredity, abnormal immunity and metabolism, trauma and other reasons cause the metabolic disorder of the natural lens, which leads to the denaturation of the natural lens protein. This phenomenon is called cataract in medicine. The most effective way to treat cataracts is to remove the natural lens surgically and replace it with an artificial lens....
