Abstract
Embodiments of the present disclosure provide improved fixation devices and fixation targets for use during optometric or ophthalmic procedures, including diagnostic and surgical procedures.
Claims20
A system, comprising:
- an optometric or ophthalmic device;
- a fixation device coupled to the optometric or ophthalmic device, the fixation device comprising:
- a near-to-eye (NTE) display device, the NTE display device configured to:
- generate a fixation target in response to receipt of a first electrical control signal;
- and
- at least one liquid lens, the at least one liquid lens configured to:
- propagate the fixation target to an eye of a patient;
- and
- deform in shape in response to receipt of a second electrical control signal, wherein the deformation in shape of the at least one liquid lens changes a focal plane of the fixation target;
- and
- a controller in communication with the fixation device, the controller configured to:
- transmit the first electrical control signal to the NTE display device to cause the generation of the fixation target;
- and
- transmit the second electrical control signal to the at least one liquid lens to cause the deformation in shape of the at least one liquid lens.
