Systems and devices for shaping human cornea and methods of use thereof

A system for shaping a human cornea of an eye comprising:

• a sapphire applanation window/suction ring (SAWSR) system,
• wherein the SAWSR system comprises a sapphire applanation window/suction ring (SAWSR), a conical holder, an illuminator, and a temperature control,
• wherein the SAWSR system is configured to:
• (i) be positioned on the eye,
• (ii) applanate the human cornea of the eye,
• (iii) generate and position a centration aid, on the eye, and
• (iv) maintain temperature control;
• an optical delivery system,
• wherein the optical delivery system comprises:
• (i) at least one laser,
• wherein the at least one laser is thermally stabilized,
• (ii) a fiber delivery holder,
• wherein the fiber delivery holder is mounted to the SAWSR,
• wherein the fiber delivery holder comprises a plurality of optical fibers,
• wherein the at least one laser is optically coupled to the fiber delivery holder, by being one of:
• 1) optically coupled individually to each fiber, and
• 2) optically coupled to the fiber delivery holder through a plurality of beamlets of light, wherein each of the plurality of beamlets of light is optically focused onto a respective proximal end of each optical fiber of the plurality of optical fibers of the fiber delivery holder;
• and
• (iii) a laser control subsystem,
• wherein the laser control subsystem is configured to display a user interface to:
• 1) at least independently control a power and a temporal waveform of each of the beamlets of light, and
• 2) irradiate the human cornea of the eye over a period of time in accordance with at least one set of treatment patterns, wherein each treatment pattern comprises a plurality of treatment areas,
• wherein each treatment area corresponds to a respective optical fiber delivering a respective beamlet of the plurality of beamlets of light, and
• wherein each treatment area is selected to minimize epithelial modifications,
• wherein each treatment area comprises a shape,
• wherein the shape is selected from the group consisting of:
• rectangular, trapezoidal, elliptical, stadium-shaped, arcuate, overlapping circular, and a combination thereof, and
• wherein each treatment area is organized into a pattern,
• wherein the pattern is selected from the group consisting of:
• trigonal, tetragonal, pentagonal, hexagonal, octagonal, annular, and a combination thereof.
