Abstract: Embodiments of the invention are generally directed to apparatus and methods for measuring a deformation characteristic of a deformable target surface. The measurement principles of the invention may be applied to a large variety of organic (e.g., human, animal or plant tissue) and inorganic materials having a surface that can be deformed by an applied non-contact force. The surface may be light diffusing and non-transparent or non-diffusing and transparent. An illustrative embodiment of the invention is directed to a device for measuring a deformation characteristic of a cornea. The device comprises a corneal topographer and a non-contact tonometer that is operationally integrated with the corneal topographer. In an aspect, the corneal topographer is a rasterstereography-based topographer. Use of the inventive device enables a method for measuring a deformation characteristic of the cornea.

Abstract: An eye imaging system, including: a light source module; a radial splitting module; a common optical module; an image receiver; a power supply module for the light source module; a driver module for the image receiver; a processing-displaying module; and a motion driving module. The image receiver is an area array sensor. The motion driving module is connected to the light source module and drives the light source module to move in a radial direction of an upstream illuminating optical path formed by the light source module and the radial splitting module. The image receiver continually opens for exposure in a radial direction of a downstream observation optical path formed by the radial splitting module and the image receiver. The continual opening of the image receiver for signal acquisition is synchronous with the movement of the light source module.

Abstract: One embodiment is a method for finding, calculating and electronically marking a reference axis for astigmatism correction/neutralization of a patient eye during a refractive surgery. The reference axis for astigmatism correction/neutralization can be determined intra-operatively based on one or more eye property measurements together with simultaneous recording a live eye image. The determined reference axis of astigmatism correction/neutralization can be updated and registered with one or more land mark(s) of the recorded eye image(s); and overlaid onto a live image of the eye. Another embodiment is a method of calculating and displaying in real time compensated refractive errors of the eye under operation with refractive components due to temporary surgically induced factors removed and refractive components due to surgeon-induced factors added.

Abstract: Spectacles having a lens frame and arms connected thereto and a retaining strap which can be fastened to the spectacles. A receiving device is provided on the free end of at least one arm, which receiving device interacts with a connecting element to which a retaining strap is undetachably fastened, e.g. moulded on. A plurality of receiving devices can be disposed at predetermined positions between the front end of each arm and the free end thereof. This has the advantage that the retaining strap can be adapted individually to the shape of the head, the hair length and possible individual preferences of the wearer of the spectacles. Thus the retaining strap can be immovably fastened not only to the free end of the arm but also to a front end of the arm, that is to say where the arm adjoins the hinge, and all intermediate positions.
