Abstract: The present invention is directed to an automated ophthalmic cataract detection using an auto-refractometer. The present invention features a method for early identification of cataracts in a patient based on spot pattern intensity. In some embodiments, the method may comprise providing an auto-refractometer comprising a Shack-Hartman sensor, and an intensity detector. The method may further comprise providing a computing device, measuring, by the Shack-Hartman sensor, a spot pattern from an eye of the patient, measuring, by the intensity detector, an intensity homogeneity value of the spot pattern, and detecting, by the computing device, a cataract in the eye of the patient based on the intensity homogeneity value. The computing device may detect the cataract if the intensity homogeneity ratio is below a threshold value.

Abstract: The present invention is directed to methods and devices for ophthalmic aberration measurement using a refractometer and phoropter. The present invention features a method for improving accuracy of measurements from an auto-refractometer to provide an optimal prescription for a patient's vision. The method may comprise measuring, by the auto-refractometer, a measurement of the patient's vision in an eye and applying, by an auto-phoropter operatively coupled to the auto-refractometer, a correction within a line of sight between the eye and the auto-refractometer. The correction may comprise an increase in visual acuity based on a correction factor. The method may further comprise repeating these steps until the patient's vision has been optimally corrected.

Abstract: The present invention is directed to an automated ophthalmic aberration measurement by an auto-phoropter. In some embodiments, the present invention features a vision testing system capable of automated calibration. In some embodiments, the system may comprise a phoropter capable of measuring the ophthalmic aberration of an eye, and providing the necessary correction. The phoropter may comprise a wavefront sensor, one or more lenses calibrated using an initial correlation factor, a model eye disposed within the phoropter for internal calibration, and a light redirection component disposed within the phoropter. The light redirection component may be capable of redirecting light into the model eye to determine an optimal correlation factor.

Abstract: The invention relates to cylindrical tunable fluidic lenses. The cylindrical optical power of the lenses may be continuously tuned within at least ±10 diopters, without inducing any significant spherical aberration, or any other significant aberrations. The lenses feature a geometry that produces minimal or no spherical defocus. These cylindrical tunable fluidic lenses could be used to induce and/or correct cylindrical optical aberrations in adaptive optical systems, particularly in ophthalmologic applications related to objective and automatic assessment of the refractive error of the eye, without the need of receiving feedback from the subjects.

Abstract: A laser ablation device which, an emitting double ring beam at the tip, is used in treatment, without permanent damage and scar, of natural diseases like venous insufficiency, of subsequently-formed diseases like fistula or of hemorrhoids formed as damaging of the vein. The device includes a fiber probe with two different conical angled surfaces where the rays guided through inside the fiber are reflected at the fiber tip via a first conical shaped-end formed at a first specific angle at the fiber's tip and a second conical shaped-end formed at different second specific angle by starting from a certain portion of the first conical shaped-end.

Abstract: An optical system includes an optical resonant cavity, an optical source, an optical detector, and a signal processing circuit. The optical source is arranged to provide a source beam of light to be at least partially coupled into the optical resonant cavity. The optical detector is arranged to detect light from the source beam of light after the source beam of light has coupled into the optical resonant cavity to provide a detection signal. The signal processing circuit is configured to communicate with the optical detector to receive the detection signal. The optical resonant cavity has a bioconjugatable lipid membrane on a surface thereof. The bioconjugatable lipid membrane is functionalized to capture a specific biomolecule, and the signal processing circuit is further configured to determine a presence of the specific biomolecule when captured by the functionalized bioconjugatable lipid membrane based on processing the detection signal.
