Abstract: A laser scanning method for forming a Fresnel type gradient index lens in an intraocular lens IOL. The radial profile of the desired optical pathlength (OPL) difference to be achieved in the IOL has multiple zones, each zone ramping from unchanged OPL to one wave, and stepping down to zero. To form a zone of a predefined OPL difference profile, the laser beam is scanned in multiple passes; in each pass, the laser beam is scanned in concentric circles of varying radii covering all or a part of the zone, with laser energy ramping up (along the radius) to a maximum allowed energy and staying at that energy. The ramp up region, which is dependent on the predefined OPL difference profile and the maximum allowed energy, is short, and most part of the pass is scanned at the maximum allowed energy.

Abstract: A method of treating a lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern of the light beam, delivering the treatment pattern to the lens of a patient's eye to create a plurality of cuts in the lens in the form of the treatment pattern to break the lens up into a plurality of pieces, and removing the lens pieces from the patient's eye. The lens pieces can then be mechanically removed. The light beam can be used to create larger segmenting cuts into the lens, as well as smaller softening cuts that soften the lens for easier removal.

Abstract: A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.

Abstract: An ophthalmic laser system and related method for forming a lenticular incision in a corneal lenticule extraction procedure. The lenticular incision is formed by multiple sweeps of a laser scan line along meridians of longitude of the lenticular incision, where the end point of each sweep is connected to the start point of the next sweep by a smooth turning trajectory. The trajectory includes a first circular arc tangentially connected to the first sweep at its end point, a second circular arc tangentially connected to the next sweep at its start point, and a straight line segment tangentially connected to both circular arcs. The smooth trajectory is determined with the given limits of velocity, acceleration and jerk of the XY scanning motors, without using high frequency filters to smooth the trajectory, thereby avoiding unknown changes to the original trajectory and achieving high precision lenticule shapes.

Abstract: A method of accommodating patient movement in a laser surgery system with a scanner. The scanner is configured to be coupled with an eye interface device and operable to scan an electromagnetic radiation beam in at least two dimensions in an eye interfaced with the eye interface device. The scanner and the eye interface device move in conjunction with movement of the eye. A first support assembly supports the scanner so as to accommodate relative movement between the scanner and the first support assembly parallel so as to accommodate movement of the eye. A beam source generates the electromagnetic radiation beam. The electromagnetic radiation beam propagates from the beam source to the scanner along an optical path having an optical path length that varies in response to movement of the eye.

Abstract: A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

Abstract: 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.

Abstract: A patient interface device for use in ophthalmic surgery, which includes a rigid body and a suction ring joined to a lower end of the body, where the suction ring includes an annular skirt made of a soft and flexible material and located at a lower end of the suction ring, and where an inner surface, and optionally an outer surface, of the skirt is coated with medication. The medication includes one or more of the following types of medication: anti-inflammatory, antibiotic, numbing, lubricating, and anti-redness. The coating method may include dip coating, sputter deposition, ultrasonic-spraying, and spin-coating. The skirt may be formed by a process that increases its material porosity and/or surface roughness, and may be surface-treated to enhance adhesion and retention of the medication.

Abstract: Some embodiments disclosed here provide for a method fragmenting a cataractous lens of a patient's eye using an ultra-short pulsed laser. The method can include determining, within a lens of a patient's eye, a high NA zone where a cone angle of a laser beam with a high numerical aperture is not shadowed by the iris, and a low NA zone radially closer to the iris where the cone angle of the laser beam with a low numerical aperture is not shadowed by the iris. Laser lens fragmentation is accomplished by delivering the laser beam with the high numerical aperture to the high NA zone, and the laser beam with the low numerical aperture to the low NA zone. This can result in a more effective fragmentation of a nucleus of the lens without exposing the retina to radiation above safety standards.

Abstract: An instrument includes: one or more scanning mirrors to receive an OCT sample beam and to scan the sample beam in two orthogonal directions; and an optical system to receive the sample beam and provide the sample beam to an eye. The optical system includes: a first lens having a first focal length, disposed along an optical path from the scanning mirror(s) to the eye at a distance from the cornea which is approximately equal to the first focal length, and a second lens disposed along the optical path between the first lens and the scanning mirror(s). The second lens receives the sample beam from the scanning mirror(s) and provides the sample beam to the first lens as a converging beam such that, as the sample beam is scanned, the sample beam passes through a pivot point located along an optical axis between the eye and the first lens.
