Abstract: An apparatus for administering a drug onto an ocular surface of a subject, the apparatus including a probe holding means for holding a probe within the apparatus. The probe has a first part being made of a bio-compatible material, and a second part being made of a magnetic material, the first part having a proximal end connected to the second part and a distal end opposite to the proximal end, wherein the distal end of the first part is employed to carry the drug. The apparatus also has an induction coil and control circuit, wherein the control circuit controls the induction coil to produce a first magnetic force and a second magnetic force, in an alternating manner, to release the probe in a first direction and to retract the probe in a second direction, respectively, wherein, when released in the first direction, the probe administers the drug from the distal end of the first part upon touching the ocular surface of the subject.

Abstract: An apparatus and a method for measuring physiological parameters of an eye. The apparatus includes a transmitter for transmitting a first set of electromagnetic waves of a first set of frequencies towards the eye, a receiver for receiving reflected electromagnetic waves corresponding to the transmitted first set of electromagnetic waves of the first set of frequencies, a comparator configured to compare the transmitted first set of electromagnetic waves with the received reflected electromagnetic waves for determining an amplitude response and a phase response for each of the electromagnetic waves of the first set of frequencies, and a calculation unit configured to fit the determined amplitude response and phase response to a physiological model of the eye to determine the physiological parameters of the eye.

Abstract: A system for measuring at least one parameter of an eye. The system includes a probe detachably arranged within a housing, wherein the probe is operable to impact a surface of the eye with a predefined impact attribute, at least one coil operable to maintain the probe within the housing, to release the probe towards the surface of the eye and to retract the probe into the housing, a probe vibration means operable to induce vibration to the probe, a measuring means for measuring a change in vibration of the probe upon impact on the surface of the eye and a controller configured to use the measured change in vibration of the probe to determine the at least one parameter of the eye.

Abstract: A device (102) for an ocular tonometer comprising a dispenser (106) for dispensing and ejecting at least one liquid droplet (302) to the cornea (304) of an eye from a distance to the eye, wherein the dispenser (106) is arranged to eject the at least one droplet (302) such that the droplet (302) causes applanation to the cornea (304). Corresponding eye pressure measuring device, arrangement and method are also disclosed.

Abstract: An alignment means of a measurement instrument includes a housing an optical component having a principal axis in a direction parallel to a desired alignment; a first light source positioned at a first distance S1 from the optical component and at a first height h1 from the principle axis; a second light source positioned at a second distance S2 from the optical component and at a second height h2 from the principle axis; and an angle barrier means arranged between the optical component, and the first and second light sources. The housing, the optical component, and the angle barrier means are arranged to block visibility of the first light source along the principal axis at a distance superior to d1?; and block visibility of the second light source along the principal axis at a distance smaller than d2, wherein d2 is smaller than d1?.

Abstract: A method of determining touch sensitivity threshold at a region of body of a human using a probe. The method includes setting first value for impact attribute of probe; releasing the probe towards the region, to impact the region with the first value for impact attribute; receiving first feedback from human in response to the impact of the probe with the first value for the impact attribute. The method further includes changing the first value of the impact attribute to set a second value; releasing the probe towards the region, to impact the region with the second value for the impact attribute; receiving a second feedback corresponding to the second value for the impact attribute. The method includes changing value of impact attribute until determination of touch sensitivity threshold as either a lowest value of sensing or a highest value of senselessness of probe based on the feedback.

Abstract: An optometric instrument includes an alignment device that includes light sources for sending out light beams through one or more light channels from the instrument onto the retina of an eye of a patient. The light channels are directed parallel with the visual axis of the eye at correct alignment, whereat the light beams are visible for the patient in an intended way. A method for aligning an optometric instrument includes sending out light beams from the light sources through one or more light channels onto the retina of the eye of a patient, and positioning the instrument to have the light channels parallel with the visual axis of the eye of the patient as a result of finding a position, wherein the light can be correctly viewed by the patient.

Abstract: The ophthalmic apparatus is aligned to an eye to be examined. The apparatus is used to examine the eye. It has two or more infrared or near infrared light sources for emitting light beams and a detector sensitive to infrared or near-infrared light with the capability of detecting the light reflected from the examinee's face. It registers the examination result of the eye examined. The ophthalmic apparatus is aligned to an eye to be examined. The light beam of one infrared or near infrared light source is directed to the face. The light beam of another infrared or near infrared light source is directed to pass the examinee. The direction of the light reflected from the examinee's face is detected and the examination result and the examined eye are registered to know whether the examined eye was the right eye or the left eye.
