Convex Contact Probe for the Delivery of Laser Energy

摘要

Systems, devices, and methods for treating a glaucomatous eye are provided. Embodiments may provide a treatment probe for treating an eye of a patient. The treatment probe may have an elongate body with a contact surface at a distal end of the elongate body. A treatment fiber or light source may be housed in the treatment probe and may be configured to direct treatment energy from the contact surface. The contact surface may be configured to couple to a surface of the eye to deliver the energy into the target area. In many embodiments the contact surface may have a convex configuration with a rounded outer shape and edge that facilitates the sweeping of the probe surface across the eye during treatment delivery. In some embodiments the probe may be swept in arc motions while delivering treatment energy to the eye.

主权项

1. A laser treatment method for an eye, the eye having a pars plana posterior to a pars plicata and a pre-laser treatment intraocular pressure, the method comprising:
providing a treatment probe for treating the eye of the patient, the treatment probe including:
an elongate body defining a handle having a proximal end and a distal end;a contact member mounted to the distal end of the handle, the contact member including a convex contact surface configured for slidingly engaging a surface of the eye; anda treatment fiber extending along the elongate body and configured for delivering a treatment laser to the eye from a distal end of the treatment fiber, the distal end of the treatment fiber protruding distally of the convex contact surface; placing the convex contact surface of the treatment probe on the surface of the eye of the patient; sliding the convex contact surface of the probe across the surface of the eye along a treatment region of the eye that is posterior to the limbus of the eye; and delivering the treatment laser to the treatment region of the eye while sliding the convex contact surface of the probe across the surface of the eye.
