Abstract

The invention discloses a marker pen for implanting an astigmatism correction type intraocular lens. The marker pen comprises a pen body, a coloring part and a cutting part, wherein dye is contained in the pen body; the coloring part is arranged at the end part of the pen body, so that the dye flows out from the coloring part; and the cutting part is arranged at the front end of the coloring part.A medical worker can complete cutting operation of corneal epithelium and the clear and fine marking operation of marking points A and B by independently using the marking pen, and does not need to cut the corneal epithelium by using a syringe needle and then perform coloring marking by using the marking pen, so that the operation steps of implanting the astigmatism correction type intraocular lens are simplified, and the operation time is shortened.

Description

technical field [0001] The invention relates to the technical field of cataract treatment, in particular to a marking pen used for astigmatism correction intraocular lens implantation. Background technique [0002] At present, cataract surgery has entered the era of refractive cataract surgery. For patients who are implanted with astigmatism-correcting intraocular lens, since the intraocular lens needs to be calculated according to the patient's corneal astigmatism size, axial direction and other parameters, the cost of astigmatism-correcting intraocular lens implantation Axial, accurate astigmatism intraocular lens implanted in the axial direction can obtain a good astigmatism correction effect, so it is necessary to mark the axial direction on the patient's cornea before the operation. [0003] In order to accurately locate the axial position of corneal astigmatism during the operation, it is necessary to accurately locate the axial line AB of the astigmatic intraocular le...
