Surgical contact lens system with a patient contact lens
In certain embodiments, a surgical contact lens system for ophthalmic treatment with a laser beam includes a patient contact lens and a surgical contact lens. The patient contact lens reduces one or more refractive errors of the eye and has a concave surface and a convex surface. The concave surface is to be disposed outwardly from a cornea of an eye. The surgical contact lens has an eye end to be disposed outwardly from the convex surface of the patient contact lens. The surgical contact lens includes a frame and an optical component coupled to the frame. The patient contact lens reduces pressure from the surgical contact lens to reduce corneal folding of a posterior surface of the cornea. The optical component of the surgical contact lens and the patient contact lens transmit the laser beam to treat the eye.
