Abstract
A method of optimizing the predictability of a vision correction procedure by comparing historical data, including the vision defect, the correction method and outcome, in terms of wavefront aberrations with a patient's condition to select an acceptable procedure. The patient's eye is examined and an optical model is created and compared to the historical data to select an acceptable procedure. The procedure is performed and the outcome is included in the data base.
Claims11
A method of intervention for correcting vision in an eye of a patient caused by defects in the eye, said method being performed with the aid of a computer system, said method comprising the steps of:
- (a) inputting categorical data for an eye of the patient with visual correction methods and outcomes;
- (b) inputting continuous data for said eye with visual correction methods and outcomes;
- (c) examining said eye and building an optical model of said eye including mapping input light rays and output light rays having a given intersection;
- (d) comparing said model with said categorical and said continuous data with visual correction methods and outcomes;
- (e) generating a procedure for said eye with a predicted outcome;
- (f) comparing said predicted outcome with said categorical and continuous outcomes to determine acceptability;
- and
- (g) performing said procedure when the predicted outcome is acceptable.
A method of optimizing the predictability of a vision correction method comprising the steps of:
- (a) inputting a set of categorical data points for an eye with visual correction methods;
- (b) inputting a set of continuous data points for an eye with visual correction methods;
- (c) inputting outcome data points for visual correction methods;
- (d) examining a patient eye and building a model of said patient eye, said model based on optics within said patient eye;
- (e) selecting a visual correction method for said patient eye based on said outcome data and generating an initial procedure recommendation;
- (f) predicting the outcome of said initial procedure recommendation for said patient eye;
- (g) evaluating said predicted outcome for acceptability;
- and
- (h) iterating a modification of said initial procedure recommendation and re-evaluating the predicted outcome until predicted outcome is acceptable.
A method of constructing a model of the eye for improved vision utilizing optical projections comprising the steps of:
- (a) establishing a wavefront for an eye;
- (b) providing a planar ray transfer element (RTE) oriented generally normal to the optical axis of said eye for passage of an incident light ray into said eye resulting in an outgoing light ray having an exit point in said eye;
- (c) locate the intersection point of said incident light ray and a vector orthogonically intersecting said wavefront from said exit point;
- (d) extending said vector to intersect said RTE;
- (e) compute the mapping change in elevation and azimuth angles at said RTE necessary to rotate said incident ray to coincide with said vector and improve vision.
