Embodiments generally relate to systems and methods for lenticular laser incisions based on wavefront maps. In an embodiment, a method comprises obtaining a wavefront map of a free eye using wavefront aberrometry to measure a refractive error, obtaining an iris image for the free eye using wavefront aberrometry, determining a free eye cutting profile to cut the cornea based on the wavefront measurement, determining a first translation of the free eye cutting profile based on estimated perturbation of the eye with a docking patient interface, docking the eye to a patient interface of an ultrashort pulsed laser system, obtaining an iris image for the docked eye, determining a second translation of the cutting profile for the docked eye from the free eye, using comparisons between the two iris images, and incising a bottom surface incision in the cornea based on the two translated cutting profiles.

A device for producing control data for a laser device for the surgical correction of defective vision. The device produces the control data such that the laser emits the laser radiation such that a volume in the cornea is isolated. The device calculates a radius of curvature R.sub.CV* to determine the control data, the cornea reduced by the volume having the radius of curvature R.sub.CV* and the radius of curvature being site-specific and satisfying the following equation: R.sub.CV*(r,φ)=1/((1/R.sub.CV(r,φ))+B.sub.COR(r,φ)/(n.sub.c−1))+F, wherein R.sub.CV(r,φ) is the local radius of curvature of the cornea before the volume is removed, n.sub.c is the refractive index of the material of the cornea, F is a coefficient, and B.sub.COR(r,φ) is the local change in refractive force required for the desired correction of defective vision in a plane lying in the vertex of the cornea, and at least two radii r1 and r2 satisfy the equation B.sub.COR(r=r1,φ)≠B.sub.COR(r=r2,φ).

For the purposes of working on eye tissue, an ophthalmological apparatus comprises a laser source that is configured to produce a pulsed laser beam, a focusing optical unit that is configured to focus the pulsed laser beam into the eye tissue, a scanner system for deflecting the pulsed laser beam onto work target points in the eye tissue, and a measurement system for optically capturing structures in the eye tissue. A circuit controls the measurement system in such a way that the latter captures a cut first outer face of a lenticule to be cut. The circuit controls the scanner system in such a way that the latter guides the pulsed laser beam onto work target points on a second outer face, positioned in relation to the captured first outer face, of the lenticule to be cut, in order to cut the second outer face of the lenticule.

Subsurface optical elements are formed within an ophthalmic lens using modulation of depth to which refractive index change inducing laser pulses are focused within the ophthalmic lens. A system for forming one or more subsurface optical structures within an ophthalmic lens comprises a control unit operatively coupled with a laser pulse source and a focusing assembly. The control unit is configured to control operation of the focusing assembly to sequentially focus each of the sequence of laser pulses onto a respective sub-volume of a sequence of sub-volumes of the ophthalmic lens. The sub-volumes of the sequence of sub-volumes have modulated depths within the ophthalmic lens and varying transverse locations within the ophthalmic lens.

Active dichoptic perceptual-learning tasks or dichoptic game play have been shown to significantly improve visual acuity of amblyopic children and adults. However, these dichoptic perceptual learning tasks are intensive and repetitive such that non-compliance is high. In contrast, the invention provides dichoptic perceptual learning in a manner that the user maintains its use and compliance is increased. Further, compliance becomes automatic if the user performs tasks in a normal manner and “forgets” that they are actually under-going treatment as it is integrated with minimal disruption to their life and activities. Accordingly, a methodology exploiting complementary dichoptic stimulation is presented.
