Embodiment 1

[0043] Such as figure 1 As shown, the replaceable multi-component multifunctional intraocular lens system described in this embodiment includes a basic lens assembly 1 and a replaceable functional lens assembly 2, and the components are connected by a snap-fit ​​structure (slot and buckle) .

[0044] The clamping groove 3 is arranged on the edge of the basic lens assembly 1, forming an angle of 90 degrees (perpendicular) to the plane of the lens assembly, and the clamping groove is trapezoidal.

[0045] The buckle 4 is arranged on the edge of the functional lens assembly 2 and forms an angle of 180 degrees (parallel) with the plane of the lens assembly. The buckle is trapezoidal and protrudes 2 mm outward.

[0046] The material of the basic lens assembly 1 is hydrophobic polyacrylate, including a lens body and two fixed haptics, the haptics are C-shaped, the span is 12 mm, and the haptic angle is 10 degrees. The lens body is 8mm in diameter and the central optic zone is 5.5m...

Embodiment 2

[0049] Compared with Embodiment 1, this embodiment differs in that the number of functional lens assemblies is two, and the functional lens assemblies are connected through the same engaging structure, such as image 3 shown.

Embodiment 3

[0051] Compared with Embodiment 1, this embodiment differs in that:

[0052] 1. The slot 3 and the buckle 4 are bonded by an adhesive to enhance the connection and fixing effect between the lens components.

[0053] 2. The card slot 3 is L-shaped, which is more convenient for assembly operation.

[0054] 3. The functional lens assembly 2 is made of hydrophobic polyacrylate.

[0055] 4. The functional lens assembly 2 has a positioning mark, specifically a colored mark located outside the central optical part and close to the buckle.

[0056] 5. The functional lens assembly 2 is a multi-focus assembly, and its function can provide patients with clear long-distance and short-distance vision at the same time.

Abstract

The invention provides a replaceable and multifunctional multi-assembly artificial lens system. The replaceable and multifunctional multi-assembly artificial lens system comprises a basic lens assembly and at least one replaceable functional lens assembly. All the assemblies are connected and fixed through clamping structures. The basic lens assembly has the main function of supporting the whole artificial lens system. The functional lens assemblies have the functions of correcting shortsightedness, farsightedness and astigmatism, improving night vision, correcting high-order phase difference and treating macular degeneration or achieving beautifying and shaping.

Description

technical field [0001] The present invention relates to intraocular lenses and, in particular, to replaceable multi-component multifunctional intraocular lens systems. Background technique [0002] After more than half a century of development, intraocular lens (IOL) implantation has become a routine method for the treatment of lens diseases such as cataract. The original lens is removed by means of extracapsular extraction or phacoemulsification, and then an IOL that can replace the refractive function of the original lens is implanted, so that the patient regains vision. With the continuous improvement of cataract surgery technology and IOL manufacturing technology, the treatment effect of IOL implantation has also put forward higher and higher requirements, from the initial limited to regaining vision, it has gradually developed into the hope of obtaining a more comprehensive and better treatment. vision, even restoring the level of vision seen in healthy young adults. ...
