Guiding-into head of artificial crystal having crystal eyes

Abstract

The invention relates to a guiding-into head of an artificial crystal having crystal eyes. The guiding-into head comprises a tubular main body, wherein the tubular main body is provided with a circumferential-direction side wall, a first end, a second end, and a penetrating inner cavity, the first end and the second end are opposite in the longitudinal direction, and the penetrating inner cavity extends from the first end to the second end in the longitudinal direction; a first U-shaped notch in the circumferential-direction side wall extends from the first end to the second end; a second U-shaped notch in the circumferential-direction side wall is opposite to the first U-shaped notch in the circumferential direction, and extends from the first end to the second end; a sheet-like positioning part outwards extends in the radial direction from the circumferential-direction side wall between the first U-shaped notch and the second end, and the longitudinal direction of the sheet-like positioning part is parallel to the longitudinal direction of the tubular main body; and when a user performs observation from the first end to the second end, the first U-shaped notch and the sheet-likepositioning part are aligned in the circumferential direction. Through the adoption of the guiding-into head disclosed by the invention, an operator does not need to manually use implantation tweezersto adjust the position or the reversing state of artificial crystalline lens.

Description

technical field [0001] The invention relates to an introduction head for a phakic intraocular lens, which can provide turning control of the intraocular lens. The invention also relates to an implant device comprising such an introduction head. The invention also relates to a method of loading a phakic intraocular lens into an introducing head. Background technique [0002] A phakic intraocular lens (PR-IOL) is an artificial lens that is surgically implanted into the posterior chamber of the eye (between the iris and the anterior surface of the natural lens) to improve the patient's postoperative corrected vision. The implanted PR-IOL remains in the patient's eye along with the natural lens. [0003] Since the PR-IOL is located between the iris and the anterior surface of the natural lens after implantation, and the anterior surface of the natural lens presents a convex shape that is approximately spherical or aspheric, the PR-IOL after implantation is not allowed to be co...

AI Technical Summary

Problems solved by technology

On the one hand, the PR-IOL squeezed into the patient's eye in this curling manner is not easy to expand; on the other hand, it may not be easy to return to the original free state after deployment because the central optic arch is always in the curled and squeezed state, or it may always be in the Squeezed deformed state, which requires further adjustment and manipulation, increasing the risk of trauma to the patient's eye tissue
