Abstract: The disclosure provides a method for correcting higher-order aberrations including providing a laser radiation. The method also includes controlling a location of a beam focal point of the laser radiation by a system of scanners and guiding the beam focal point in such a way that the location of the beam focal point is in a cornea of an eye. The method further includes introducing the laser radiation into the cornea of the eye. The method includes cutting a lenslet, wherein a thickness of the lenslet t(X,Y) satisfies a following equation: t(X,Y)=t0+Δt(X,Y)/(n−1), where Δt(X,Y) represents a higher-order wavefront elevation and t0 represents the thickness of the lenslet having a spherical refractive power of D.

Abstract: Disclosed herein are systems and methods for adjusting an intraocular lens (IOL) with optical coherence tomography (OCT) guidance. The IOL can comprise an optic portion and a plurality of haptics. In one embodiment, a method can comprise directing a laser beam generated by a laser system at a composite material making up part of the IOL. At least part of the composite material can expand in volume in response to the laser beam directed at the composite material. The method can also comprise measuring a volume change of the composite material or a change in at least part of the IOL by analyzing OCT images produced by an OCT imaging apparatus and determining a change in a base power of the IOL based on the measurements.

Abstract: Disclosed herein is a method of performing ophthalmic surgery. The surgery includes positioning a patient interface relative to a patient's eye with the patient interface at least partially defining an interface chamber with the patient's eye. The interface chamber is filled with an immersion fluid. A fluid in an anterior chamber of the patient's eye is replaced with the immersion fluid, wherein the immersion fluid matches the refractive index of the cornea. A laser system is positioned relative to the patient interface. The laser system includes a laser source configured to generate a femtosecond laser beam and an optical delivery and scanner system in communication with the laser source to direct 3D scanned and focused laser beams through the patient interface and into the patient's eye.

Abstract: Disclosed herein are systems and methods for compensating for a tilt of an intraocular lens (IOL) and systems and methods for adjusting the IOL. For example, one of the methods can comprise capturing one or more optical coherence tomography (OCT) images of an eye of a subject when the IOL is implanted within the eye of the subject. The method can also comprise generating a fixation target such that the fixation target is visible to the eye of the subject and moving the fixation target until a transverse plane of the IOL is perpendicular or substantially perpendicular to an optical axis of an ophthalmic system. The method can also comprise directing a laser beam generated by a laser of the ophthalmic system at the IOL.
