Intravital surgery system for scanning type laser operation of hot forming cornea

Abstract

A scanning laser operation system for the thermo-shaping operation of cornea on living body is composed of a scanning laser source, an adaptive locating system, a safte parameter testing system, a therapeutic effect testing system, and a controller.

Description

technical field [0001] The invention relates to a system in the technical field of biomedical engineering, in particular to a living body operation system for scanning laser keratoplasty. Background technique [0002] As people's understanding of hyperopia continues to deepen and the number of hyperopic people continues to grow, the treatment of hyperopia is becoming more and more a hot spot in the field of ophthalmology. There are several methods for the treatment of hyperopia, including excimer laser refractive keratotomy, excimer laser in situ keratomileusis, laser thermoplasty, clear lens extraction combined with intraocular lens implantation, automatic lamellar Keratoplasty, Keratotomy, Lasso and more. Among them, laser keratoplasty is the use of laser light to irradiate the cornea, so that the corneal collagen fibers are heated and contracted, and the refractive power of the cornea is changed to treat ametropia. Since laser thermoplasty is a non-invasive treatment us...

AI Technical Summary

Problems solved by technology

Although this system reduces the time-consuming of laser keratoplasty, reduces corneal epithelial damage and corneal infection, and improves the accuracy of the action site compared with the early contact beam fiber probe, but because the system is still only able to Produces a limited photocondensation point, so the formed shrinkage ring is still unpredictable

Therefore, there is still the defect that the stability and predictability of the treatment effect are relatively poor.
