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] like figure 1 , figure 2 As shown, the present embodiment provides an intraocular lens that is not easy to stick and climb, including a lens-like main body and a supporting plate 1. At least two supporting plates 1 extend radially along the edge of the crystal-like main body. Woven fibre structure 2 or metal foil type material.

[0042] Because the braided fiber structure 2 or metal foil-type material is embedded in the support plate 1 in this technical solution, the resilience of the corresponding part of the intraocular lens can be enhanced, and the toughness of the structure can be enhanced, so that when the support plate 1 is unfolded, the resilience is enhanced and reduced. The possibility of sticking to the support 1 allows the intraocular lens to be unfolded smoothly after entering the lens capsular bag, even if different people have different operating techniques, different IOL sizes, different bolus tubes, and curled IOLs. Different methods, different length...

Embodiment 2

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

[0045] The crystal-like body includes a central optical zone 3 and an annular edge zone 4 around the central optical zone 3, and the annular edge zone 4 is embedded with a woven fiber structure 2 or a metal foil type material.

[0046] It should be noted that the woven fiber structure 2 or the metal foil type material can be arranged in a circle along the annular edge region 4, and can also be arranged in an arc-shaped structure with 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, comprising the following steps:

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

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

[0051] The intraocular lens material mixture comprises the following components by mass content: 30% of phenethyl acrylate, 65% of phenethyl methacrylate, 3% of ethylene glycol diacrylate and 2% of AIBN;

[0052] S2. Weaving 40um 40% polyurethane fiber into a sheet to form a woven fiber sheet;

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

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

[0055] 2) drying and cleaning the braided fiber structure: drying the cleaned braided fiber structure at a temperature of 60 degrees to obtain ...

Abstract

The invention relates to the technical field of intraocular lens production, and discloses an intraocular lens that is not easy to stick to and a manufacturing method thereof. The intraocular lens includes a crystal-shaped main body and a support bracket, and the support bracket is radially extended along the edge of the crystal-shaped main body. At least two, the braided fiber structure or metal foil type material is embedded in the support; the invention provides a kind of intraocular lens that is not easy to stick to climbing and its manufacturing method, which can enhance the resilience of the corresponding parts of the intraocular lens, and can strengthen the structure The toughness increases the rebound force when the support rod is deployed, reduces the possibility of the support rod sticking, and enables the intraocular lens to expand smoothly after entering the lens capsular bag.

Description

technical field [0001] The invention relates to the technical field of intraocular lens manufacturing, in particular to an intraocular lens that is not easy to stick and a method for manufacturing the same. Background technique [0002] In the process of intraocular lens implantation, the intraocular lens needs to be curled, put into the injector, push the push rod of the injector, the intraocular lens is passed through the thin tube, into the lens capsular bag, and then needs to be unfolded naturally, and the intraocular lens implantation is completed. Because the material of the intraocular lens is generally soft, and each time the intraocular lens is implanted, the operation method is different, the size of the intraocular lens is different, the size of the bolus tube is different, and the method of curling the intraocular lens is different. The length of time to implantation varies, so that the rate of natural expansion of intraocular lenses after implantation is not hig...
