Abstract: Provided are systems and methods for correcting a corneal surface irregularity in a subject. The system generally comprises a infrared laser, for example, and infrared laser and a laser control unit, a corneal contacting unit, a gel solidifying unit and an electronic device tangibly storing algorithms to operate the units. In the methods, a polymerizable or thermo-reversible gel or polymerized resin is applied to the anterior corneal surface and solidified as a layer over the cornea. A first correcting cut is lasered into the stroma of an applanated cornea, the gel layer is then removed and a second correcting cut is lasered in the stroma of the applanated cornea. The lenticule formed intrastromaly by the first and second correcting cuts is removed such that the cornea has a corrected corneal curvature.

Abstract: An embodiment in accordance with the present invention provides an apparatus and method for injecting a lens into a flap or pocket in the cornea. This lens or pocket preferably is created by a laser used in conventional lasik surgery. The apparatus includes a syringe or handle, a plunger extending movably through the lumen of the syringe, and a paddle. The paddle extends from the distal end of the syringe and is configured to hold the lens to be injected into the eye. The paddle also defines a fluid flow path in fluid communication with the lumen of the syringe and configured to allow saline to flow onto the paddle to lift the lens from the paddle, such that the lens can be inserted into the eye.

Abstract: Provided herein are a devices, ophthalmic lens systems and methods for restoring natural tension and anatomy of a lens capsule post-surgically in an eye of a subject. The device generally comprises an inward tensioning ring-like structure having a shape configured to circumferentially fit within and be anchored to a post-surgical lens capsule of the eye. The device may have one or both of external and internal grooves formed to receive the lens capsule and one or both of an intraoptical lens or a tensioning element. The ophthalmic lens system generally comprises the device and an intraocular lens inserted therein. The anchored device provides tension to an equatorial area of the capsule resulting in a decrease in equatorial diameter.

Abstract: An automated mechanical device separates the epithelial layer of a cornea from the cornea. The device includes a separator such as a plate, wire or dull blade. The device can preserve a separated epithelial layer as a disk without rupturing the disk and without substantial epithelial cell loss. The epithelial layer is separated from the cornea without cutting the cornea.

Abstract: An apparatus and method for measuring refractive characteristics of human eyes with an objective refraction measuring device for measuring refraction in at least one eye, the objective refraction measuring system having a proximal end and a distal end, the objective refraction measuring system suitable for looking in the proximal end and seeing out the distal end; an open field visual target. An open viewing lane is provided between the eye and the open field visual target, the viewing lane has sufficient length to allow for focusing the eye at infinity and for natural accommodation at true distance targets, such near distances such as reading distances. The objective refraction measuring device can be positioned in the viewing lane to measure the eye while the eye is focused on the open field visual target.

Abstract: Eye refraction is measured to achieve desired quality via a selected vision characteristics. A characteristic of vision is selected to correlate to the desired quality of vision from a group of vision characteristics comprising acuity, Strehl ratio, contrast sensitivity, night vision, day vision, and depth of focus, dynamic refraction over a period of time during focus accommodation, and dynamic refraction over a period of time during pupil constriction and dilation. Wavefront aberration measurements are used to objectively measure the state of the eye refraction that defines the desired vision characteristic. The measured state of refraction is expressed with a mathematical function enabling correction of the pre-selected vision characteristic to achieve the desired quality of vision. The mathematical expression function may be a Zernike polynomial having both second order and higher order terms or a function determined by spline mathematical calculations.

Abstract: A separator is disclosed for moving a separated portion of an eye. The separator includes an upper surface. A lower planar surface is oriented at an angle with respect to the upper surface. The upper surface and the lower planar surface define an edge therebetween having a structure to remove a portion of an eye. The upper surface includes a structure to receive the removed portion of the eye and to roll the removed portion.

Abstract: An instrument for measuring aberration refraction of an eye is provided, having: a lens system defining an instrument optical axis and an alignment device for aligning the visual axis of the eye with the instrument optical axis. A light source produces a probing beam that is projected through the lens system parallel to the instrument optical axis and is selectably positionable partially off-set from the instrument optical axis for entering the eye parallel to the instrument optical axis at a plurality of locations on the cornea of the eye. A first photodetector measures the position of a first portion of the probing beam light scattered back from the retina of the eye to measure aberration refraction of the eye at a plurality of locations. A second photodetector synchronously measures the position of a second portion of the probing beam light reflected back from the cornea of the eye.
