CORNEAL REFRACTIVE CORRECTION USING A SURFACE TREATMENT AFTER CORNEAL RESHAPING
20220110792 · 2022-04-14 ·

The present disclosure relates to a system for treating a cornea of a human eye using laser radiation. The system includes a laser system and a control system, which is configured to control the laser system for performing (a) a reshaping laser ablation for ablating a portion of a stroma of the cornea; and (b) a laser surface treatment. The laser surface treatment is a substantially optically non-corrective treatment of a reshaped surface portion. The reshaped surface portion represents a corrective or non-corrective reshaping of an anterior surface of the cornea and is formed using the reshaping laser ablation. A maximum ablation depth of the laser surface treatment is less than 5 micrometers or less than 3 micrometers.

An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.

In certain embodiments, an ophthalmic laser ablation system comprises a laser device, liquid remover, and computer. The laser device directs laser radiation towards an eye as a plurality of shots to ablate tissue of the eye according to a treatment pattern. The liquid remover removes liquid from a surface of the tissue of the eye. The computer: determines a moisture maintenance procedure; instructs the liquid remover to remove the liquid from the surface of the tissue at a location of the eye according to the moisture maintenance procedure; and instructs the laser device to ablate the tissue at the location of the eye according to the treatment pattern.

Planning device and method for generating control data for an ophthalmological laser therapy device for structures bridging the cornea in a pressure-reducing manner

A planning device that generates control data for an ophthalmological laser therapy appliance with a laser device and a control unit, includes a first interface for supplying various data and a second interface for transferring the control data to the control unit of the ophthalmological laser therapy appliance, which is embodied to generate control data for a scanning pattern for the ophthalmological laser therapy appliance from the supplied data, by application of which scanning pattern a structure can be produced in the cornea, the limbus, and/or the sclera of a patient's eye. The planning device is embodied to generate from the supplied data, control data for the scanning pattern of this structure and/or a structure for receiving the shunt implant.
