Problems solved by technology

[0005] As an improved accommodative intraocular lens, although the thickness of the lens can be adjusted, but because the degree of change is relatively small, the vision correction effect is not obvious, and it can only be reflected in the movement of Qin's suspensory ligament. Two-dimensional movement, so the range of its accommodation power is relatively narrow, so it can only be applied to patients over 45 years old whose eyeball's own accommodation power is weakened

Embodiment Construction

[0077] Among them, 1) the shapes, sizes, proportions, angles, and quantities shown in the drawings are only schematic, so some changes may occur. 2) The drawings are shown based on the viewer's line of sight, so the directions and positions described in the drawings may change in various ways depending on the position of the viewer. 3) Even when the reference numbers are different, the same reference symbols may be used for the same parts.

[0078] 4) In the case of using terms such as "comprising, equipped with, consisting of", unless terms such as "only ~" are used at the same time, other parts may be added. 5) When described in the singular form, it may also be interpreted as the plural form. 6) Regarding the comparison of shape, size, and positional relationship, etc., even if it is not described in the form of "approximately, substantially", etc., it should be interpreted as including a general error range.

[0079] 7) Even when terms such as "after ~, before ~, next, s...

Abstract

The invention discloses an intraocular lens which can improve the refractive power change of the lens by receiving the movement of the suspension ligament of the fraxini. The present invention, as an intraocular lens inserted into a capsular bag, comprises an optical part and a tactile part, and the optical part comprises an anterior membrane, a posterior membrane, and an internal space. The optical portion receives external motion through the tactile portion and changes its shape. The optical portion can obtain an additional adjustment force by means of a curvature difference between the inner side surfaces of the front and rear films, thereby providing a lens having a wider refractive power range.

Description

technical field [0001] One embodiment of the present invention relates to an intraocular lens fitted within a capsular sac. Background technique [0002] As a treatment method for ophthalmic diseases in which the lens is abnormal, such as cataracts, artificial intraocular lenses are inserted into the corresponding space after removing the contents of the lens (lens) inside the capsular bag (capsular sac). (intraocular lens) surgery. [0003] By inserting an intraocular lens, the artificial lens can be used instead of the natural lens to provide the patient with clear vision without clouding. The problem with existing intraocular lens insertion procedures is that after the procedure the anterior and posterior capsules of the capsular sac stick to each other, losing the ability to transmit the relaxation and contraction of the Zonule of Zinn. The original function of adjusting the thickness of the lens. [0004] That is, after the operation, the patient's eyes cannot active...
