Abstract
FIELD: medicine. SUBSTANCE: artificial eye lens has optical and carcass parts made on the basis of methacrylate, and these components were taken at the following ratio, wt.-%: 2,2-dimethoxy-2-phenylacetophenone 0.1-1.1; oligoethermethacrylate 28-58, and oligourethanmethacrylate - the rest. Optically clear solid artificial eye lens were prepared after photohardning of material. Variant of an artificial lens containing the following components: methylcarbitol methacrylic ester of the formulaand 10 groups of CH-CHin oligoethermethacrylate. These components were taken at the following ratio, mas.-%: 2,2-dimethoxy-2-phenylacetophenone 0.1-1.1; oligoethermethacrylate 0.5-5.0; methylcarbitol methacrylic ester 28-80, and oligourethanmethacrylate - the rest. Optically clear elastic lens were prepared after photohardening. Lens were able to twist and recover its form. Lens shows small specific gravity, active property, etc. EFFECT: enhanced quality of lens.

и 10 групп CH2 - CH2 в олигоэфирметакрилате, при этом все вышеуказанные компоненты взяты в следующем соотношении, мас.%: 2,2-диметокси-2-фенилацетофенон 0,1-1,1, олигоэфирметакрилат 0,5-5,0, метакриловый эфир метилкарбитола 28-80, олигоуретанметакрилат - остальное. После светоотверждения получаем оптически прозрачный, эластичный, способный к восстановлению первоначальной формы после кратковременной формы деформации, необходимой для имплантации, искусственный хрусталик.The invention relates to medicine, and specifically to ophthalmology. An object of the invention is the creation of a reactive artificial lens with a small specific gravity, the ability to curl and restore a previously given shape. To achieve this, the artificial lens of the eye, containing the optical and supporting parts based on methacrylate, according to the invention contains components in the following ratio, wt. %: 2,2-dimethoxy-2-phenylacetophenone 0.1-1.1, oligoester methacrylate 28-58, oligourethane methacrylate - the rest. After light curing, we get an optically transparent, hard artificial eye lens. There is a variant of the artificial lens, in which it additionally contains: methacrylic ester of methylcarbitol
and 10 groups of CH 2 - CH 2 in oligoester methacrylate, with all the above components taken in the following ratio, wt.%: 2,2-dimethoxy-2-phenylacetophenone 0.1-1.1, oligoester methacrylate 0.5-5.0 , methylcarbitol methacrylic ester 28-80, oligourethane methacrylate - the rest. After light curing, we get an optically transparent, elastic, capable of restoring its original form after a short-term form of deformation necessary for implantation.
