Abstract: According to certain embodiments, an ophthalmic surgical system for treating presbyopia comprises controllable components and a computer. The controllable components comprise a light source that generates a light beam and a scanner that directs a focal point of the light beam. The computer determines an ablation profile to remove tissue from a central region and a peripheral region of a cornea of a first eye of a pair of eyes. The ablation profile is designed to remove tissue from the central region to yield a protrusion to provide for near-vision, and to remove tissue from the peripheral region to correct to emmetropia.

Abstract: In certain embodiments, an ophthalmic surgical system for creating a lenticule in the cornea of an eye comprises controllable components (including a laser source and a scanner) and a computer. The laser source generates a laser beam, and the scanner directs the focal point of the laser beam. The computer determines a lenticule design for the lenticule having a posterior side and an anterior side. Either the posterior side or the anterior side has a central portion and a peripheral portion. The lenticule design is formed using a major lenslet and a minor lenslet, where the major lenslet is designed to correct to emmetropia. The lenticule design is formed by subtracting the minor lenslet from the major lenslet, where the subtraction of the minor lenslet yields the central portion. The computer instructs one or more of the controllable components to create the lenticule.

Abstract: In certain embodiments, an ophthalmic surgical system for ablating tissue of an eye comprises controllable components (such as a light source and a scanner), optical elements, and a computer. The light source generates a light beam comprising pulses, where a propagation direction of the light beam defines a z-axis. The scanner directs a focal point of the light beam in an xy-plane orthogonal to the z-axis. The optical elements shape and focus the focal point of the light beam at a treatment region of the eye. The computer instructs one or more of the controllable components to generate the light beam comprising the pulses, where each pulse has a fluence greater than 1 J/cm2. An optical element of the optical elements focuses the focal point of the light beam with a spot size of less than 0.4 mm at the treatment region according to a focal spot pattern.
