| 20100152565 | NON-INVASIVE TONOMETER - Tonometers are disclosed for measuring intraocular pressure (IOP) and having an ocular probe movable a predetermined distance in a linear manner by a motor against the closed eyelid of a patient's test eye, a distance sensor configured to monitor the probe position as the probe is moved against the eyelid and provide a distance measurement, a mechanism for aligning the probe with the center of the cornea underneath the closed eyelid, and a force sensor configured to measure force on the ocular probe as it is moved against the closed eyelid by the motor and provide a force measurement, wherein a value indicative of IOP of the test eye is determined from the force and distance measurements. Methods for measuring IOP using the inventive tonometers are also disclosed. | 06-17-2010 |
| 20110054291 | Eye tonometry apparatus, systems and methods - A system for measuring intraocular pressure (IOP) of an eye, comprising a plurality of force sensors that are adapted to contact a surface of an eye, means for measuring the forces exerted on the force sensors when in contact with the eye surface, and processing means that is adapted to receive the measured forces and determine IOP of the eye as a function of the measured forces. | 03-03-2011 |
| 20120108941 | APPLANATION TONOMETER AND METHOD FOR MEASURING THE INTRAOCULAR PRESSURE OF THE EYE - An applanation tonometer for measuring intraocular pressure (IOP) so that the health of a human or animal eye can be determined. The applanation tonometer includes a prism having a contact tip at one end to be moved into contact with and lightly touched against the cornea or the eye. Incident laser light is transmitted inwardly through the prism to the contact tip at which some of the light is decoupled and lost though the contact tip depending upon the area of contact between the contact tip and the cornea. The remaining light is reflected by the contact tip outwardly through the prism. A photo defector which is responsive to the light reflected by the contact tip of the prism and a force detector which is responsive to the pressure at the area of contact between the contact tip and the cornea generate paired force and area data pairs that are processed to measure IOP. | 05-03-2012 |
| 20120265047 | INTRAOCULAR PRESSURE DETECTING DEVICE AND DETECTING METHOD THEREOF - An intraocular pressure detecting device includes an optical module and a data processing unit. The light module transmits a light beam to an eyeball and acquires at least one light interference signal of a reflected light beam reflected from a cornea and a reference light beam. The light module electrically couples with the data processing unit, which determines an intraocular pressure detection area according to the at least one light interference signal. The data processing unit utilizes the at least one light interference signal acquired by the light module to calculate the intraocular pressure. | 10-18-2012 |
| 20130296681 | OPTICAL INTRAOCULAR PRESSURE MEASURING APPARATUS AND OPERATING METHOD THEREOF - An optical intraocular pressure measuring apparatus includes a light source, an optical module, a pressure providing module, a deformation measuring module, and a processing module. The light source provides an incident light. The optical module divides the incident light into a first incident light and a second incident light and emits them to a reference object and an object to be detected through a first light path and a second light path, and receives a first reflected light signal from reference object and a second reflected light signal from the object to be detected respectively. The pressure providing module coupled with second light path provides a pressure to deform the object to be detected. The deformation measuring module measures the deformation of the object to be detected. The processing module processes the first reflected light signal and second reflected light signal to generate an intraocular pressure measurement result. | 11-07-2013 |
| 20130317335 | Applanation Tonometry Apparatus and Case for Transport and Use Thereof - A case for transportation and use of an applanation tonometry apparatus includes a housing including a base and a wall structure extending upwardly therefrom, the housing sized to receive the applanation tonometry apparatus therein. A lid is pivotally connected to an upper rim of the wall structure, the lid having a closed position overlying the housing and an open position rotated away from the housing, the lid supporting the applanation tonometry apparatus in the open position. A handle is pivotally connected to the lid and has a stored position within the lid and a use position rotated away from the lid, the handle supporting the lid in the open position by engagement with a support surface. | 11-28-2013 |
| 20140371569 | COLORING SUBSTANCE FOR DIAGNOSTIC OPHTALMOLOGIC USE - The present invention relates to a substance selected from the group consisting of riboflavin, its esters, salts and hydrates thereof, for use in an ophthalmic diagnostic method. In preferred aspects of the invention, the riboflavin is applied into the eye as part of a solution having a concentration from about 0.01 and 0.5% riboflavin or acceptable salt, ester, hydrate thereof. | 12-18-2014 |
| 20160029888 | APPLANATION TONOMETER HAVING CORNEA ALIGNMENT MEANS - An applanation tonometer for providing a measurement of intraocular fluid pressure inside the eye of a patient. The applanation tonometer includes a light-transmitting prism having a cornea contact tip at one end and a cornea alignment aid at the opposite end. The cornea alignment aid enables the patient to advise a vision professional when a light source of the tonometer is properly aligned with his cornea so that intraocular fluid pressure can be accurately measured. A light-blocking baffle is located at the opposite end of the prism, and a thin light-transmitting channel is formed through the baffle to lie on the longitudinal axis of the prism. In a preferred embodiment, the light baffle is at least one opaque disk, and the light-transmitting channel is a clear spot at the center of the opaque disk through which light is transmitted to the patient's cornea. | 02-04-2016 |
