[Preliminary results of an algorithm for customized soft contact lens ablation].

PURPOSE: To develop a computer simulation for customized soft contact lenses in order to correct aberrations of higher order.

METHODS

Using real data from a patient diagnosed with keratoconus, which were measured using a Hartmann-Shack wavefront sensor, the thickness of the contact lenses that compensate these aberrations as well the numbers of pulses required to ablate the lenses were specifically determined for the patient.

RESULTS

The maps of correction are presented and the numbers of pulses are calculated, using a 0.5 mm beam width and a 0.3 microm ablation depth.

CONCLUSIONS

The results shown here are promising, but they should be improved so that the ablation in actual physical systems can reach the desired accuracy.
