Abstract: A vision testing method and apparatus are disclosed, the method including generating an image, modulating the wavefront of the image remote from the patient, relaying the modulated wavefront to a plane nearby, on, or within the patient's eye, varying the modulation of the wavefront based upon patient or operator response, and conveying the value of the wavefront modulation to the operator. The apparatus includes devices for generating an image, modulating the wavefront of the image that is physically remote from the patient, optically relaying the modulated wavefront of the image to a plane nearby, on, or within a patient's eye, varying the modulation of the wavefront of the image based upon patient or operator response, and conveying the value of the continuously modulated wavefront to the operator.

Abstract: A vision testing method and apparatus are disclosed, the method including measuring the modulation to a wavefront of light that is imparted by an intra-ocular lens, determining the wavefront modulation necessary to emulate the optical properties of the IOL after it replaces the crystalline lens in a patient's eye, generating a static or dynamic image viewable by a patient, modulating the wavefront of the image remote from the patient to attain the wavefront that necessary to emulate the optical properties of the IOL after it is implanted, and relaying said wavefront to a plane nearby, on, or within the patient's eye.

Abstract: The present disclosure provides systems and methods for diagnosing and treating subjects using neuro-ocular wavefront data. As such, in some embodiments, among others, neuro-ocular wavefront data is obtained, and one or more characteristics of a visual system are ascertained from the neuro-ocular wavefront data.

Abstract: A method, materials, and medical devices are disclosed for providing an intralamellar insert between opposing layers formed in the cornea. Upon preparing the cornea by partially separating a flap of tissue, a gel or similar material is placed thereon and conformed to desired dimensions to correct refractive errors of the cornea.

Abstract: A unitary, pressure-regulating corneal implant device for use in controlling intraocular pressure of the cornea is disclosed, the implant having a conduit with a bore and a porous core material disposed in the bore for allowing egress of aqueous humor from the anterior chamber of the eye. The conduit is elongated for extending from the ocular surface of the eye substantially flush therewith through the corneal stroma, and into the anterior chamber.

Abstract: An accommodating lens is designed to be inserted into a substantially intact capsulary bag having a capsulorexis opening in its anterior wall. The lens has an accommodating portion adapted to be affixed to the anterior wall of the capsulary bag adjacent the opening. The focal length of the deformable portion is alterable by insertion of a deforming material into the deformable portion thereof. In another embodiment, the focal length of a second deformable portion of the lens is varied by insertion or extraction of deformable material into or from the second portion.

Abstract: A lenticule is bonded to the eye as part of its formation process by curing or final curing the lenticule on the eye. Such lenticules provide a smooth transition from the body of the lenticule to Bowman's layer on which the lenticule is disposed. The lenticule at the time its material or precursor is placed on the eye may vary from being essentially all viscous collagen which flows and must be molded to obtain a desired lenticule configuration to a substantially stable preform which holds its own shape. Such preformed lenticules may be formed using an appropriate mold and photopolymerization or other partial curing techniques to pre-cure the lenticule material to an appropriate stage for application to the eye.

Abstract: An aircraft landing information system is disclosed which provides to the aircraft pilot information regarding the actual and preferred sink rate of the aircraft, the distance between the landing gear wheels and the runway, and deviation of the actual sink rate from the preferred sink rate. An altitude determining sensor is provided on the aircraft and the information transmitted therefrom is fed into a microprocessor or like system which then presents the relevant data to the pilot in an audio and/or visual format to allow the pilot to touch down at the preferred sink rate.

Abstract: A spatially resolved map of the eye's refractive characteristics are provided by measuring the eye's refractive characteristics on a point-by-point basis across the anterior surface of the eye. This spatially resolved refraction data may be obtained subjectively by providing a reference pattern and a measurement beam, by establishing a particular position on the cornea as the location to be measured and manipulating the orientation of the measurement beam at that measurement point to bring the measurement beam to a desired position relative to the reference image. When the patient indicates that the measurement beam is in the desired position relative to the reference pattern, the orientation of the beam is recorded as the refractive data for that measurement point and the process proceeds to another measurement point. This provides relatively rapid, physiologically accurate refractive data on a spatially resolved basis.

Abstract: Eye alignment is determined by producing a combined iris/retinal image by use of an imaging system. The relative position of the centroid of the pupil and various structures on the retina is indicative of the eye alignment. The eye alignment may be determined by comparing a combined iris/retinal image at the present time with a stored iris/retinal image at a past time. The imaging system may be a laser scanning ophthalmoscope.

Abstract: An apparatus and process for applying a synthetic lenticule to the cornea of a human eye is disclosed, the process also contemplating selective reprofiling of the lenticule while it is in place over the cornea. The process involves securing the lenticule over the cornea with an adhesive, thus leaving the visual axis of the eye undisturbed or with the peripheral edge thereof being retained by a peripheral slit. A laser delivery system is used to reprofile the lenticule if necessary for refining the refractive power of the lenticule.

Abstract: An apparatus and process for applying a synthetic lenticule to the cornea of a human eye is disclosed, the process also contemplating selective reprofiling of the lenticule while it is in place over the cornea. The process invlolves ablating a shallow peripheral groove in the cornea to receive the peripheral edge of the lenticule which is then secured therein with an adhesive, thus leaving the visual axis of the eye undisturbed. The lenticule is placed over the cornea with a unique micromanipulation apparatus and normally under vacuum conditions. A laser delivery system is used to reprofile the lenticule if necessary for refining the refractive power of the lenticule.
