Description

Positioner for artificial lens fixing operation

Technical Field

The invention relates to the technical field of medical instruments, in particular to a positioner for intraocular lens fixation.

Background

Intraocular lens scleral affixation is a common method for implanting intraocular lenses in aphakic capsular bags. Fixation requires that the two haptics of the intraocular lens are positioned symmetrically about the sclera, e.g., at 4 o 'clock and 10 o' clock, and are spaced from the limbus by a distance of 2-3 mm. In addition, with the popularization of astigmatic intraocular lenses, the positioning requirements for implanting intraocular lenses are becoming more and more accurate. If the position or distance is deviated during fixation, the position deviation of the artificial lens, diopter deviation, deformation of the vision of the patient, and the like may occur, and the ciliary body or the retina may be damaged, causing hemorrhage in the eye.

However, in the prior art, the fixation of the intraocular lens is often performed by experience, and the error is large due to various subjective factors, the age of the patient, the degree of limbal senile ring, the degree of fitting, and the like. Especially for children patients, the eyeball changes greatly, and the sclera marking operation cannot be carried out before the operation, so that large errors are easily caused, the accurate judgment of the fixing position of the intraocular lens is influenced, and the operation effect is influenced. To date, no instrument for accurately positioning the position and distance of the corneal or scleral clock has been available in clinic and on the market.
