Background

At present, cataract surgery has entered the era of refractive cataract surgery, for a patient with an astigmatism correcting intraocular lens implanted, because the intraocular lens needs to calculate the axial direction in which the astigmatism correcting intraocular lens needs to be implanted according to the astigmatism size, the axial direction and other parameters of the cornea of the patient, and the accurate astigmatism intraocular lens implantation axial direction can obtain a good astigmatism correcting effect, the axial direction marking needs to be carried out on the cornea of the patient before surgery.

To accurately locate the axis of corneal astigmatism during surgery, it is necessary to accurately locate the axis AB of the astigmatic intraocular lens (through the pupil center point O) prior to surgery, i.e., through the two points labeled A, B to determine the axis AB of the astigmatic intraocular lens. The existing marking method usually uses a 1ml syringe needle, before use, the surface of the cornea is anesthetized, then a narrow light band of a slit lamp is used, the angle of the light band is adjusted to an axial angle, then a thin line is drawn on the peripheral cornea or the corneal scleral margin by using the tip of the 1ml syringe needle, and then a marking pen is used for marking a point A on the cornea on which the corneal epithelium is drawn. Then marking the point B on the opposite side at the position on the opposite side by using a general method, and then checking the marking accuracy by a light band of a slit lamp, or marking a horizontal reference point of 0 and 180 degrees under the slit lamp, and further marking the axial direction of the intraocular lens during the operation.

In the process, the existing cornea marking method has certain problems, the corneal epithelium needs to be scratched by using a syringe needle, and then the marking pen is used for coloring and marking, so that the steps are complicated and the time consumption is long.
