Abstract: An endurance haptic system is disclosed herein. The endurance haptic system includes a plurality of tactors, a plurality of air bladders, a tactor driver operably coupled to the plurality of tactors and configured to send vibration commands to the plurality of tactors in response to a first signal received from an aircraft controller, and an air bladder driver operably coupled to the plurality of air bladders and configured to inflate and deflate the plurality of air bladders in response to a second signal received from the aircraft controller.

Abstract: A system is disclosed herein, including a cushion including a plurality of tactors and a plurality of air bladders disposed adjacent the plurality of tactors, a pump assembly operably connected to the plurality of bladders, a processor, and a memory operatively coupled to the processor. The memory includes instructions stored thereon that, when executed by the processor, cause the processor to determine an inflation sequence for the plurality of air bladders, determine a deflation sequence for the plurality of air bladders, output commands to the pump assembly corresponding to the inflation sequence and the deflation sequence, and output vibrate commands to the plurality of tactors.

Abstract: An accommodative intraocular lens (IOL) system is disclosed for insertion into an eye to provide accommodative vision, the system including a deformable air chamber filled with a transparent, low refractive index medium disposed between the first and second optics; and at least one haptic connected to the air chamber and configured to facilitate a change in the curvature of at least one surface of the chamber, such that when the lens system is positioned in an eye, cilliary muscle movements can alter the curvature of the air chamber and vary the overall lens power of the system.

Abstract: In one aspect, the present invention provides methods for custom fabrication of IOLs. In some embodiments, such methods call for measuring one or more aberrations of a patient's eye, and determining the profile of at least one surface of an IOL that would ameliorate, and control those aberrations. The surface profile can then be imparted to a surface of a starting lens (or a lens blank) via ablation, e.g., by utilizing an excimer laser beam. In some other embodiments, the measured aberrations can be utilized to determine the profile of at least one surface of a wafer mold. A wafer mold having that surface profile can then be fabricated, e.g., by ablating a slab or an existing wafer of appropriate material, and the mold can be used to fabricate an IOL suitable for implantation in the patient's eye.

Abstract: In one aspect, the present invention provides an intraocular lens that includes a posterior optic and anterior optic. The optics have different chromatic dispersions adapted to cooperatively provide compensation for natural chromatic aberrations of the eye over a wavelength range of interest, e.g., over a wavelength range of about 400 nm to about 700 nm.

Abstract: The present invention provides monofocal ophthalmic lenses that exhibit extended depth of field while providing sufficient contrast for resolution of an image over a selected range of defocus distances. In some embodiments, a lens of the invention can include a refractive surface having controlled surface modulations relative to a base profile. The surface modulations are designed to extend a depth of field of the lens such that a single image can be resolved, albeit with somewhat less contrast, over a range of distances greater than the focal region of a conventional lens. The ophthalmic lenses of the invention can be employed in various vision correction applications, including, but not limited to, intraocular lenses, contact lenses, instrastromal implants and other refractive devices.

Abstract: A diffractive optical ICL made from two different hydrogel materials that are biologically acceptable for long term implantation in the cornea. The first material has a higher refractive index than the cornea and it is bound to the second material which has a refractive index similar to corneal tissue. The interface between the two materials consists of a microstructured diffractive surface. The adequate permeability of metabolites through both of the hydrogels of the diffractive ICL yields a safe implant for the cornea. Alternatively, the lens may be made of a single material and/or have an edge geometry that minimizes corneal irritation and allows the lens to sit within the corneal tissue smoothly and relatively flat.
