Abstract: Embodiments of the invention provide methods and systems for analyzing the ophthalmic anatomy of a patient posterior to the cornea. The method may include scanning a focus of a femtosecond laser beam along a path within the patient's eye. A portion of the path may be disposed posterior to the patient's cornea. The method may also include acquiring a first reflectance image and a second reflectance image associated with the focus disposed respectively at a first location of the path and a second location of the path. The method may further include determining the presence or absence of an ophthalmic anatomical feature of the eye based on a comparison between the first reflectance image and the second reflectance image.

Abstract: Systems and methods for analyzing the anatomy of a patient's eye with circular or rotated polarized laser beams, or with laser beams of different wavelengths are disclosed. One system includes a polarization beam-splitter and a quarter-wave plate, wherein the quarter-wave plate is configured to circularly rotate a laser beam received from a laser that is transmitted and passes through the polarization beam-splitter, and to transform a circularly rotated back-reflected beam to a linearly polarized laser beam that is perpendicular to the beam that was transmitted through the polarization beam-splitter. Substantially all of the back-reflected beam is directed to a photo-detector for analysis. A Faraday rotator subsystem may be substituted for a polarization beam-splitter. An optical system including a laser that generates a laser beam of a first wavelength for therapeutic treatment, and another laser that generates a laser beam of a second wavelength for measurement is also disclosed.

Abstract: An imaging system. An array of light sources and an array of lenses corresponding to the light sources and having optical axes substantially parallel to one another are provided. The lenses produce collimated output beams. An afocal optical relay having an optical axis substantially parallel to the optical axes of the lenses is also included, the array of lenses being positioned relative to the afocal optical relay so as to form an optical system that produces an image of each collimated output beam on an image plane, each image having a prescribed depth of focus and spot size. The light sources preferably are lasers producing an array of respective laser beams having high intensity and a long waist. A system for writing information on a light-sensitive label includes the imaging system. Methods of imaging and of writing information on a light-sensitive label are also provided.

Abstract: The present disclosure is generally directed towards methods and devices for reducing or eliminating reflection-illuminated artifacts. The methods and devices in several embodiments can include providing a transparent lens cover with a blocking member for reflecting or absorbing internally-reflected light. The lens cover can be attached at the distal end of an endoscope, cannula, and/or lumen in some embodiments. Alternatively, the lens cover can be a permanent part of the endoscope, lumen, and/or cannula.

Abstract: Disclosed herein are various systems and methods for improving the visualization of an optical device, in particular a medical device. The device can include a lens cover that provides an offset between the distal end of an endoscope and the surrounding environment. At least a portion of the lens cover can have an ellipsoidal shape.
