Capsulorhexis apparatus

Abstract

The present invention provides a capsulorhexis apparatus for incising the anterior capsule covering a crystalline lens by being inserted into an incised portion of the cornea, the capsulorhexis apparatus comprising: an anterior capsule incision part which has a closed curve shape, is inserted into an incised portion of the incised cornea to thus circularly incise the anterior capsule positioned in the lower portion of the cornea, and generates heat by using high frequency vibration in order to incise the anterior capsule; a body part which is externally exposed when the anterior capsule incision part incises the anterior capsule while the anterior capsule incision part slidingly moves, and is internally inserted when the anterior capsule incision part does not incise the anterior capsule; and a button part which is formed in one surface of the body part and slidingly moves the anterior capsule incision part on the inside of the body part. Accordingly, the present invention can precisely circularly incise the front surface of the anterior capsule covering a crystalline lens, thus being capable of preventing revision surgery caused by surgery failure, and enabling surgery to be safe and easy.

Description

technical field [0001] The present invention relates to a capsulorhexis apparatus, and more particularly, to a capsulorhexis apparatus capable of making clean and precise circular cuts to the anterior surface of the anterior capsule that covers the lens of the eyeball. Background technique [0002] Referring to the background technology of patent document KR 2010-0016724, the eye (or eyeball 1) as a part of the body is an organ that ensures a clear field of view by sensing the intensity and wavelength of light, and as figure 1 As shown, the eye (or eyeball 1 ) includes a cornea 20, a colorless transparent lens 30, an iris 40 and a retina (not shown). The cornea 20 is formed to cover the exterior of the sclera 10 and is formed of transparent avascular tissue so as to refract light. The lens 30 functions as a lens of a camera. The iris 40 contains pigments that determine the color of the pupil, and the iris 40 functions as an aperture for adjusting the amount of light enteri...

AI Technical Summary

Problems solved by technology

[0007] Therefore, by using such conventional cutting tools, it is difficult to cleanly and precisely cut the lens capsule 50 to an appropriate size and shape (in particular, a circle), and in severe cases, the anterior capsule may be radially dissected. ruptures, and the intraocular lens (not shown) may not be implanted properly, resulting in endophthalmitis or requiring reoperation to replace the intraocular lens

[0008] Moreover, because the anterior surface of the lens capsule 50 needs to be moved very carefully many times while cutting the anterior surface of the lens capsule 50, the procedure is very difficult and time consuming.
