Abstract: Embodiments of this invention generally relate to systems and methods for optical treatment and more particularly to non-invasive refractive treatment method based on sub wavelength particle implantation. In an embodiment, a method for optical treatment identifies an optical aberration of an eye, determines a dopant delivery device configuration in response to the optical aberration of the eye, wherein the determined dopant delivery device is configured to impose a desired correction to the eye to mitigate the identified optical aberration of the eye by applying a doping pattern to the eye so as to locally change a refractive index of the eye.

The plenoptic detector is configured to selectively receive images of the first set of light sources reflected from a corneal surface of the eye and generate first plenoptic image data representing the images of the first set of light sources. The plenoptic detector is further configured receive images of the second light source reflected from a retina of the eye and generate second plenoptic image data representing the images of the second light source.

Abstract: Embodiments described herein provide improved systems and methods for corneal pachymetry. These systems and methods can be used to improve the accuracy of corneal measurements that are used for a wide variety of different ophthalmic procedures. One embodiment provides a system and method for corneal pachymetry using a plenoptic detector. For example, a corneal pachymetry system can comprise a light source, a plenoptic detector and a processing system coupled to the plenoptic detector. The light source is configured to illuminate the cornea of the eye, and the plenoptic detector is positioned at an angle relative to the eye. The plenoptic detector is configured to receive an image of the light source reflected from the cornea and generate plenoptic image data representing the images. The processing system is coupled to the plenoptic detector and is configured to analyze the plenoptic image data to accurately determine the corneal thickness of the eye.

Abstract: A method and associated system improve accuracy in objective refraction measurements by including the measured distance between the photoreceptors of a subjects eye and the scattering location of light during the objective refraction measurements. Chromatic aberrations in the objective measurements are also compensated. The distance between the photoreceptors and the scattering location may be determined by adjusting a distance between a rotating speckled light pattern and an eye until the speckled light pattern appears to be stationary, or by employing a Scheiner disk.

Abstract: An enhanced dynamic range wavefront sensing system includes a light source disposed on a first side of an optically transmissive device, a wavefront sensor disposed on a second side of an optically transmissive device, a relay imaging system disposed between the optically transmissive device and the wavefront sensor, and means for adjusting a distance between the light source and the optically transmissive device. Beneficially, the relay imaging system includes a range-limiting aperture to insure that the wavefront sensor never goes out of range so that a feedback system can be employed to move the light source one focal length away from the optically transmissive device.

Abstract: A method of measuring aberrations of a three-dimensional structure of an optical system, such as an eye, includes creating a plurality of light beams, optically imaging the light beams and projecting the light beams onto different locations in an optical system, receiving scattered light from each of the locations, and detecting individual wavefronts of the scattered light. The plurality of light beams may be created and projected simultaneously or sequentially. A system for measuring aberrations of a three-dimensional structure of an optical system includes a light source creating a plurality of light beams, an optical imaging system optically imaging the light beams and projecting the light beams onto different locations in the target optical system, and a wavefront sensor receiving scattered light from each of the locations and detecting individual wavefronts of the scattered light.

Abstract: An ophthalmic error measurement system includes a projecting optical system delivering light onto a retina of an eye, a pre-correction system which compensates a light beam to be injected into the eye for aberrations in the eye, the pre-correction system being positioned in between the projecting optical system and the eye, an imaging system which collects light scattered by the retina, and a detector receiving light returned by the retina from the imaging system. Use of the pre-correction system allows the end-to-end aberrations of the ocular system to be analyzed. The use of a pre-correction system also allows use of a minimized spot size on the retina, and all of its attendant advantages.
