The present disclosure is directed to contact lenses for the correcting a refractive error, particularly astigmatism, and other corneal irregularities. An exemplary lens comprises an inner portion, a peripheral portion, and a juncture therebetween. The inner portion provides optical correction for an eye. The peripheral portion conforms to a corneal surface of the eye. The juncture is a structurally flexible portion of the ophthalmic lens such that deformation of the peripheral portion in response to conforming to an astigmatism or higher order aberration of the corneal surface does not substantially deform the inner portion. When the lens is placed on the eye, the inner portion vaults over the corneal surface to form a lenticular volume. The optical correction is provided by a combination of the inner portion and the lenticular volume.

Astigmatism correcting contact lenses

Contact lenses for the treatment of a refractive error, particularly astigmatism, are provided. An exemplary lens comprises a soft continuous lens body configured to cover a corneal surface, the lens body having a posterior surface to be suspended over the corneal surface forming a free volume thereover, and at least one discrete discontinuity. The free volume may be configured to fill with tear fluid, forming a tear lens over the corneal surface for correcting the ocular refractive error. The discrete discontinuity may allow a portion of the lens body to conform to a meridian of the eye without substantially distorting an optical region of the lens body. The discrete discontinuity may allow tear fluid to flow into and out of the free volume to form the tear lens. Optical correction is provided by a combination of the optical region of the lens body and the tear lens.

Spherical astigmatism correcting contact lenses

The invention provides an axisymmetric soft contact lens having aspheric and/or spheric geometrical design for use in correcting an ocular refractive error of an eye.

Methods and systems for performing an eye test and for detecting eye disease. A test pattern is presented to an individual. The individual fixates an eye on a fixation target. The test pattern is then hidden and a second test pattern is displayed at a different location. The individual then compares the perceived second test pattern with a pre-defined reference pattern. These steps are repeated several times, while varying the location of presentation of the patterns. Alternatively, the individual fixates on a presented fixation target. A test pattern is presented to the patient and then disappears. The individual compares the perceived pattern, with a pre-defined reference pattern. These steps are repeated while changing the location of presentation of the test pattern. It may then be determined whether the individual has an eye disease based on the comparisons.

Methods devices and systems for detecting eye disease

Methods and devices for detecting eye disease and for assessing the clinical stage of an eye disease in an individual. The methods include projecting test patterns onto the retina of a tested eye and subjecting the individual to a competing sensory stimuli. The competing stimuli may be of various different sensory modalities including visual, auditory, or other sensory modalities. If the individual perceives a difference in at least one localized part of the perceived image of a test pattern as compared to a predefined reference pattern, the individual provides a response indicative of the difference or differences. The responses are processed to assess the severity of eye disease if a disease is detected, or to determine the clinical stage of a detected eye disease.

Methods, devices and systems for assessing eye disease

A method and system for detecting eye disease. A pattern is displayed on a screen to an individual, who is made to fixate his vision on a point in the pattern. The pattern is then hidden and a second pattern is displayed. The individual then compares the second pattern, as perceived by him, with a pre-defined pattern. These steps are then repeated several times. It is then determined whether the individual has an eye disease based on the comparisons.
