Corneal retention or stabilizing tool

Abstract

Described here is a surgical device that typically is used to releasably hold the cornea of a human eye (and hence that eye) in such a way as to modestly deform the cornea and the eye, to maintain the eye's position for procedures upon the epithilial layer of the cornea, and to allow ease of replacement of an epithilial flap should one be produced. It may be used in combination with an epithilial delaminating tool, or an ocular device inserting tool. The stabilization device permits ready access to and creation of flaps or pockets of epithelium for later introduction of correcting lenses (e.g. using an ocular device insertion tool) or subtractive procedures such as LASIK or LASEK, prior to replacement of epithelium over the corrective lens or over the site of laser induced or surgically-induced corrective procedure.

Description

technical field [0001] The present invention relates to a surgical device typically used to releasably retain the cornea of ​​a human eye (and thus the eye) by moderately deforming the cornea and eye in order to correct the upper The cortex is operated on to keep the eye in place and, if an epithelial flap is created, the flap can be easily repositioned. This surgical device may be used in conjunction with an epithelial delamination tool or a vision device insertion tool. This stabilizing device allows easy access and creation of flaps or pockets of epithelium prior to repositioning of the epithelium on corrective lenses or at the site of laser-induced or surgically-induced corrective procedures for later introduction of corrective Lenses (eg, using a vision device insertion tool) or subtractive procedures, such as LASIK or LASEK. Background technique [0002] Refractive surgery refers to a group of surgical procedures that alter the original optical power or focusing abil...

AI Technical Summary

Problems solved by technology

There are several problems with epikeratophakia: 1) the lens remains cloudy until the parental stromal fibroblasts colonize the lens, which can take several months; 2) until the engrafted epithelium is able to The severed epithelium remains the focus of infection until the incised site grows onto the surface of the lens; and 3) the epithelium that heals onto the surgical site sometimes migrates into the space between the lens and the parent cornea

However, this "bandage" cannot restore the epithelium to its original state, i.e., it cannot preserve the integrity of the epithelium, thereby reducing its clarity, water-impermeability, and barrier function

In turn, the ability of the epithelium to adhere to the stromal surface of the cornea is also impaired
