OPHTHALMIC LASER SURGICAL SYSTEM AND METHOD FOR WAVEFRONT-GUIDED CORNEAL LENTICULE EXTRACTION FOR VISION CORRECTION
A ophthalmic laser-assisted corneal lenticule extraction procedure that uses wavefront measurements to guide the formation of the corneal lenticule. The wavefront map measured from a free eye using a wavefront aberrometer is registered to the cornea of a docked eye based on comparisons of iris images and corneal markings. The docked-eye cornea-registered wavefront map is then corrected to be consistent with the Munnerlyn formula for the spherical power, and adjusted for any physician adjustments and/or myopia error due to a flat add in the lenticule, using Zernike polynomials. The corrected and adjusted wavefront map is then used to calculate the profiles of the bottom and top lenticule incisions in the applanated cornea, where higher-order components in the wavefront map are distributed to the bottom lenticule incision alone and lower-order components in the wavefront map are distributed to both the bottom and the top lenticule incision.
Methods and systems for cataract surgery using intraocular illumination
A method for cataract surgery includes incising a continuous curvilinear capsulorrhexis (CCC) in an anterior capsule of a lens of an eye, inserting an endoillumination probe into the lens through the CCC, further inserting the endoillumination probe to a location below an equator of the lens and below a nucleus of the lens, tilting the endoillumination probe to laterally aim light emitted from the endoillumination probe behind the nucleus, and chopping the nucleus with a chopper needle of the endoillumination probe. The chopping further includes chopping the nucleus with a phaco tip.

EYE SURGERY METHOD USING SURGICAL CANNULATED INSTRUMENT
An eye surgery method includes incising a cornea of an eye using a blade portion of a surgical cannulated blade instrument to create an opening in the cornea, injecting injectable into an anterior chamber of the eye through the opening by a lumen of the surgical cannulated blade, and stabilizing the eye by engaging an increasing diameter portion of the surgical cannulated blade with the opening.
SYSTEM AND METHOD FOR LASER CORNEAL INCISIONS FOR KERATOPLASTY PROCEDURES
A first image of the eye is generated when the cornea of the eye is exposed to a gas. The cornea is covered with an optic of a patient interface. A second image of the eye with the patient interface over the cornea is generated. In this second image, the patient interface distorts the second image of the eye. One or more of a position or an orientation of the eye is determined in response to the first image and the second image when the patient interface has been placed over the cornea.

LIMITED DEPTH CORNEAL PUNCH
A single-use adjustable depth trephine corneal punch device that allows a goal trephination depth of a donor cornea to be set and cut prior to a surgical procedure for cutting selected portions of an actual patient cornea. The corneal punch includes a punch block having a central well for receiving a donor cornea, a punch top mounted atop the punch block and having a central cylindrical opening coaxially aligned with the well, and means for cutting a selected portion of the donor cornea in the central well, wherein the means for cutting includes a punch blade mounted atop the punch top and through the opening for combined limited rotation less than about 312 degrees and limited axial movement from a reference or “start” point and into juxtaposed relation against the cornea and a limited axial downward movement during rotation wherein to make a shallow cut in the cornea.
