Retinal Imaging of Low Light Signals
This technology enables high resolution in vivo images of the retina by a technique of simultaneous image capture and dual registration, which corrects for the natural movement of the living eye to enable many imaging frames to be combined to increase the signal to noise ratio from very weak signals, such as those from fluorescence or phase imaging,...

Retinal Imaging with Adaptive Optics Optical Coherence Tomography (AO-OCT)
Adaptive optics is used in optical coherence tomography (OCT) to provide very high axial resolution in a non-invasive "optical sectioning" technique for imaging at various depths within living human tissue. In the current commercial application of OCT for retinal imaging, the transverse resolution is limited by the intrinsic ocular aberrations...

Improving Vision and the Resolution of Retinal Images by Measuring and Correcting the Wave Aberration of the Eye
This describes the use of wavefront measurement and adaptive optics to correct all the aberrations of the human eye.ApplicationsWavefront measurement of all the aberrations in the human eye can make possible correction of vision which goes beyond conventional spectacles and contact lenses. This correction of higher order aberrations can be applied...

Novel Intra-Ocular Pressure Regulating Device
Applications:The current invention proposes a novel intra-ocular pressure regulating device to aid in current glaucoma research and to treat human eye conditions such as hypotony (low eye pressure) which when chronic, can lead to debilitating loss of vision. This is based on a novel eye pressure regulated animal model of reversible elevated eye pressure...
