Problems solved by technology

Because the material of the intraocular lens is generally relatively soft, and each time the intraocular lens is implanted, the operation method is different, the size of different intraocular lenses is different, the size of the pipe of different injectors is different, and the method of curling the intraocular lens is different. The length of time from implantation to implantation is different, so that the rate of natural expansion after implantation of intraocular lens is not high
The above problems are due to the insufficient resilience of the material after the climbing is curled, making it difficult to unfold the climbing. The above problems will also bring a lot of inconvenience to the doctors and patients who are on the operating table, and even lead to the failure of the operation.

Embodiment 1

[0041] Such as figure 1 , figure 2 As shown, this embodiment provides an intraocular lens that is not easy to stick to and climb, including a lens-like body and a support ring 1, at least two support rings 1 are radially extended along the edge of the crystal-like body, and the support ring 1 is embedded with Woven fiber structure 2 or metal foil type material.

[0042] Because the braided fiber structure 2 or metal foil type material is embedded in the support climbing 1 in this technical solution, the resilience of the corresponding part of the intraocular lens can be enhanced, the toughness of the structure can be enhanced, and the resilience of the support climbing 1 is enhanced when the support climbing 1 is unfolded. The possibility of support climbing 1 sticking allows the intraocular lens to unfold smoothly after entering the lens capsular bag, even if different people operate differently, different intraocular lenses have different sizes, different injector tubes ha...

Embodiment 2

[0044] This embodiment is optimized on the basis of the above-mentioned embodiment 1.

[0045] The crystalline body comprises a central optical zone 3 and an annular edge zone 4 located around the central optical zone 3, in which a braided fiber structure 2 or a metal foil type material is embedded.

[0046] It should be noted that the braided fiber structure 2 or the metal foil material can be arranged in one circle along the annular edge region 4 , or in an arc-shaped structure that is less than one circle.

Embodiment 3

[0048] The present invention also provides a method for making an intraocular lens that is not easy to stick to and climb, comprising the following steps:

[0049] S1. Prepare fiber material and intraocular lens material mixture;

[0050] The fiber material is 40% polyurethane fiber;

[0051] The intraocular lens material mixed solution includes the following components in mass content: 30% phenylethyl acrylate, 65% phenylethyl methacrylate, 3% ethylene glycol diacrylate and 2% AIBN;

[0052] S2, weaving 40um 40% polyurethane fibers into sheets to form woven fiber sheets;

[0053] S3, cutting the braided fiber sheet into the shape of an intraocular lens to form a braided fiber structure;

[0054] S4, 1) Cleaning the braided fiber structure: cleaning the braided fiber structure by ultrasonication for 2 minutes with ethanol and deionized water respectively;

[0055] 2) drying the cleaned woven fiber structure: drying the cleaned woven fiber structure at a temperature of 60 degr...

Abstract

The invention relates to the technical field of intraocular lens manufacturing and discloses an intraocular lens not easy to stick and climb and a manufacturing method thereof. The intraocular lens comprises a crystalline body and at least two support climbs. The support climbs extend along the radial direction of the edge of the crystalline body, and a braided fiber structure or a metal foil typematerial is embedded in the support climbs; according to the intraocular lens not prone to sticking and the manufacturing method of the intraocular lens, the resilience force of the corresponding part of the intraocular lens can be enhanced, the toughness of the structure can be enhanced, the resilience force is enhanced when the supporting climb is unfolded, the possibility that the supporting climb is stuck is reduced, and the intraocular lens can be smoothly unfolded after entering a lens bag.

Description

technical field [0001] The invention relates to the technical field of intraocular lens production, in particular to an intraocular lens that is not easy to stick to and a production method thereof. Background technique [0002] During the implantation of the intraocular lens, it is necessary to curl the intraocular lens, put it into the injector, push the push rod of the injector, the intraocular lens enters the thin tube, enters the lens capsular bag, and then needs to climb naturally to complete the implantation of the intraocular lens. Because the material of the intraocular lens is generally relatively soft, and each time the intraocular lens is implanted, the operation method is different, the size of different intraocular lenses is different, the size of the pipe of different injectors is different, and the method of curling the intraocular lens is different. The length of time until implantation is different, so that after the implantation of the artificial lens, the...
