| 20100249569 | Non-contact ultrasonic tonometer - A non-contact ultrasonic tonometer for measuring an intraocular pressure of an examinee's eye in non-contact manner by use of an ultrasonic wave, comprises: an ultrasonic transducer including a transmitter which emits an ultrasonic transmission pulse wave to the eye and a receiver which detects an ultrasonic reflection pulse wave from the eye, the transducer being arranged to be placed in a position apart from the eye and to transmit and receive the pulse wave with respect to the eye through the medium of air; and a calculation part being arranged to obtain a peak amplitude level of the reflection pulse wave based on an output signal from the ultrasonic transducer and measure the intraocular pressure based on the obtained peak amplitude level. | 09-30-2010 |
| 20100312087 | NON-CONTACT ULTRASOUND MEASUREMENT DEVICE - A non-contact ultrasound measurement device comprises: a first unit including an ultrasound transducer adapted to transmit and receives an ultrasonic wave in a non-contact manner with respect to an object to be examined, the first unit being adapted to process an output signal from the transducer and measure a first characteristic of the object; and a second unit including at least one of an observation unit for observing the object from front in a non-contact manner and a measurement unit for measuring a second characteristic of the object from front in a non-contact manner, wherein the transducer comprises: an aperture being provided in the central part of the transducer and having a sufficient size to be utilized for observation or measurement of the object by the second unit, and a transmitting and receiving part of the ultrasonic wave being provided to surround the aperture. | 12-09-2010 |
| 20100324406 | NON-CONTACT ULTRASONIC TONOMETER - A non-contact ultrasonic tonometer comprises: a ultrasonic transducer that transmits an ultrasonic pulse wave to an examinee's eye and receives the ultrasonic pulse wave reflected from the eye in a non-contact manner; a transmission unit that transmits a drive signal to the ultrasonic transducer to cause the ultrasonic transducer to repeat transmission of the ultrasonic pulse wave K times at a constant interval 1/T in order to transmit a burst wave to the eye, where “T” is a burst frequency and “K” is a burst wave number that is the number of cycles of pulse wave; and an arithmetic unit that determines intraocular pressure (IOP) based on an output signal from the ultrasonic transducer when the ultrasonic transducer receives the burst wave reflected from the eye. | 12-23-2010 |
| 20120277569 | Optic Characteristic Measuring System and Method - The invention teaches a method, apparatus and system for measuring bio-medical attributes of the eye, such as internal or intraocular pressure. The invention enables taking measurements of the relative location of various surfaces of components of the eye under different conditions. The invention provides for applying a pressure disturbance to the eye acoustically and, using non-invasive optical techniques to perform measurements of vibrations or measurements of the time varying relative location of one or more surfaces or structures in a manner correlated with the pressure disturbance. | 11-01-2012 |
| 20130085370 | SYSTEMS AND METHODS FOR APPLYING AND MONITORING EYE THERAPY - In systems and methods for generating cross-linking activity in an eye, a feedback system monitors a biomechanical strength of the eye in response to the photoactivation of a cross-linking agent applied to an eye. The feedback system includes a perturbation system that applies a force to the eye and a characterization system that determines an effect of the force on the eye. The effect of the force provides an indicator of the biomechanical strength of the eye. The characterization system determines the effect of the force on the eye by measuring an amount of deformation caused by the force or a rate of recovery from the deformation. | 04-04-2013 |
