Abstract
A method of producing intra-ocular lenses or contact lenses including the following steps: a) mechanically forming a lens blank such that it is suitable for correcting an ametropic visual defect, b) measuring the aberration of an eye to be corrected, c) calculating an ablation profile with respect to the lens blank on the basis of the measured aberration, and d) ablating material of the lens blank in accordance with the calculated ablation profile by means of laser radiation.
Claims4
A method of producing an intra-ocular lens comprising at least the following steps:
- a) mechanically forming a lens blank (60) such that it is suitable for correcting a visual defect selected from the group consisting of myopia, hyperopia, and astigmatism;
- b) measuring the aberration of an eye to be corrected;
- c) calculating an ablation profile (62) with respect to the lens blank (60) obtained by step a) on the basis of the measured aberration;
- and
- d) ablating material of the lens blank (60) in accordance with the calculated ablation profile (62) by means of laser radiation (34).
A method of producing a contact lens comprising at least the following steps:
- a) mechanically forming a lens blank (60) such that it is suitable for correcting a visual defect selected from the group consisting of myopia, hyperopia, and astigmatism;
- b) measuring the aberration of an eye to be corrected;
- c) calculating an ablation profile (62) with respect to the lens blank (60) obtained by step a) on the basis of the measured aberration;
- and
- d) ablating material of the lens blank (60) in accordance with the calculated ablation profile (62) by means of laser radiation (34).
