Systems and Methods for Generating Patient-Specific Corneal Cross-Linking Treatment Patterns

An automated process receives input tomography data and generates an optimized (customized) treatment pattern for an individual patient without relying on the physician's analysis and judgment. For example, a method for treating a cornea includes receiving tomographic data for a cornea. The method includes identifying a keratoconic defect in the cornea based on the tomographic data. The method includes segmenting the keratoconic defect into treatment zones based on predefined geometric parameters, wherein the treatment zones indicate where a cross-linking agent is to be applied on the cornea and photoactivated to treat the keratoconic defect.

OPHTHALMIC DOCKING SYSTEM WITH 3-DIMENSIONAL AUTOMATIC POSITIONING USING MAGNETIC SENSING ARRAY
20220110790 · 2022-04-14 ·

A magnetic positioning system and related method for automated or assisted eye-docking in ophthalmic surgery. The system includes a magnetic field sensing system on a laser head and a magnet on a patient interface to be mounted on the patient's eye. The magnetic field sensing system includes four magnetic field sensors located on a horizontal plane for detecting the magnetic field of the magnet, where one pair of sensors are located along the X direction at equal distances from the optical axis of the laser head and another pair are located along the Y direction at equal distances from the optical axis. Based on relative magnitudes of the magnetic field detected by each pair of sensors, the magnetic field sensing system determines whether the patient interface is centered on the optical axis. The system controls the laser head to move toward the patient interface until the latter is centered on the optical axis.

Projection of defocused images on the peripheral retina to treat refractive error

An apparatus to treat refractive error of the eye comprises one or more optics configured to project stimuli comprising out of focus images onto the peripheral retina outside the macula. While the stimuli can be configured in many ways, in some embodiments the stimuli are arranged to decrease interference with central vison such as macular vision. The stimuli can be out of focus images may comprise an amount of defocus within a range from about 3 Diopters (“D”) to about 6 D. In some embodiments, the brightness of the stimuli is greater than a brightness of background illumination by an appropriate amount such as at least 3 times the background brightness. In some embodiments, each of a plurality of stimuli comprises a spatial frequency distribution with an amplitude profile having spatial frequencies within a range from about range of 1×10.sup.−1 to 2.5×10.sup.1 cycles per degree.
