    摘要: There is disclosed herein a system for correcting a refractive condition of an eye having a cornea, the system comprising: a laser subsystem operable to produce a non-ultraviolet, ultrashort pulsed beam having a wavelength in the range of 400nm to 3000nm; a patient interface configured to applanate the cornea during an intrastromal incision, the pulsed beam being directed through the patient interface and into the cornea; a scanner operable to direct the pulsed beam at the eye; and a controller coupled to the laser subsystem and the scanner, the controller configured to: determine an intrastromal incision pattern based on the refractive condition; and direct the scanner to intrastromally incise the pattern in the cornea with the pulsed beam, the refractive condition being corrected by the pattern intrastromally incised in the cornea following de-applanation of the cornea by the patient interface, wherein the pattern has a maximum radius of about 5 mm and a minimum radius of about 1 mm, wherein the pattern has a minimum depth from an anterior surface of the cornea of about 50 microns and a maximum depth of about 50 microns toward the anterior surface from an endothelium of the cornea, and wherein the pattern comprises a group of ring incisions.

    摘要: A method of inserting and securing a corneal implant in engaging and fluid-flow limiting relation to the posterior cornea, such as to treat edema. The method includes securing a corneal implant in fluid flow limiting relation to the posterior cornea through an incision in the eye and securing it in place by a variety of steps such as corneal insertion or laser bonding, and preferably by inserting a removable corneal implant including a central region and a plurality of retention member(s) disposed on the periphery thereof into the eye so as to releaseably and removably engage a portion of the eye and thereby retain the corneal implant in abutting and engaging relation with the posterior cornea. The retention members of the corneal implant may also comprise haptic leg(s) extending from the central region and having a biasing configuration structured to be disposed in contacting relation with the iris and/or iridocorneal angle in biasing relation of the central region against the posterior cornea.
