Abstract
Devices, systems, surgical kits and methods for corneal surgery, preferably using femto-laser assisted, corneal tattooing. The corneal tattoos are formed with one or more viscous opaque substances such as pasty substances of different colors to match eye colors of different patients.
Claims24
A method of performing corneal tattoo surgery:
- selecting an incision location, size and depth for a corneal flap or pocket;
- then
- transmitting laser pulses to a lens of an eye of a patient to generate the corneal flap, channel or pocket;
- then
- applying a corneal tattoo substance to a corneal layer and/or corneal tissue to form a corneal tattoo.
2 more elements
A surgical tool for corneal tattooing, comprising:
- a handle with a shaft that is attached to a corneal applicator, the corneal applicator sized and configured to push against an exposed internal corneal layer of a cornea to distribute a viscous, opaque corneal tattoo substance.
A surgical kit or set of components for treating an eye, comprising:
- a surgical tool with a corneal applicator;
- and
- at least one container of a medical grade corneal tattoo substance, wherein the corneal tattoo substance is formulated to be opaque and viscous.
A femtosecond laser surgical system for eye treatments, comprising:
- a femtosecond laser;
- a controller in communication with the laser, the controller comprising or in communication with a corneal tattoo module, wherein the corneal tattoo module allows a user to select laser inputs including a corneal channel depth between 100 and 300 μm;
- and
- a display having a user interface in communication with the controller, wherein the user interface allows a user to overlay a virtual ring over an image of an eye of a patient to identify a desired a ring size of an internal corneal layer in-line with a region of an iris over a pupil.
