Abstract
Methods, devices, and systems establish an optical surface shape that mitigates or treats presbyopia in a particular patient. The combination of distance vision and near vision in a patient can be improved, often based on input patient parameters such as pupil size, residual accommodation, and power need. Iterative optimization may generate a customized corrective optical shape for the patient. Threshold residual accommodation is established for presbyopia treatment.
Claims15
A method of determining whether to provide a patient with a presbyopia treatment, the patient having an eye with a pupil, the method comprising:
- inputting a pupil dimension;
- inputting a pupil dimension response associated with a change in viewing condition of the eye;
- calculating a threshold residual accommodation of the eye based on the pupil dimension and the pupil dimension response;
- and
- determining whether to provide the patient with the presbyopia treatment based on a comparison of a residual accommodation of the eye with the threshold residual accommodation calculated for the eye.
A system for determining whether to provide a patient with a presbyopia treatment, the patient having an eye with a pupil, the system comprising:
- an input that accepts a pupil dimension;
- an input that accepts a pupil dimension response associated with a change in viewing condition of the eye;
- and
- a first module coupled with the pupil dimension input and the pupil dimension response input, the first module configured to calculate a threshold residual accommodation of the eye based on the pupil dimension and the pupil dimension response, the threshold residual accommodation suitable for use in determining whether to provide the patient with the presbyopia treatment.
