System for manufacturing an optical lens
View Patent ↗A system for manufacturing an optical lens that is configured to correct optical aberrations, including, e.g., high order aberrations such as described by Zemike polynomials. The system can include a measurement system configured to measure optical aberrations in a patient's eye and to create measured optical aberration data. A calculation system is configured to receive the measured optical aberration data and to determine a lens definition based on the measured optical aberration data. A fabrication system is configured to produce a correcting lens based on the lens definition.
1. A method of customizing vision correction, comprising:
measuring optical aberration data of a patient's eye;
calculating a lens definition based on the optical aberration data, wherein calculating the lens definition comprises calculating a correction of at least one low order aberration and at least one high order aberration and is based at least partly on the patient's pupil size; and
fabricating a correcting lens based on the lens definition wherein said correcting lens comprises a photosensitive gel layer between a first and a second optical element and said photosensitive gel layer is a matrix polymer having a monomer mixture dispersed therein and is cured.
2. The method of claim 1 , wherein fabricating the correcting lens comprises adjusting only low order aberrations.
3. The method of claim 1 , wherein fabricating the correcting lens comprises applying a low order correction to a framed lens.
4. The method of claim 1 , wherein fabricating the correcting lens comprises exposing the first and second optical element to curing radiation.
5. The method of claim 1 , wherein fabricating the correcting lens comprises depositing one or more monomer layers having a pattern of thickness to achieve the low order lens definition.
6. The method of claim 1 , wherein calculating the low order lens definition comprises calculating at least one low order aberration and at least one high order aberration.
7. The method of claim 1 , wherein calculating the lens definition is further based on at least one of a patient's vertex distance, pupil distance, gaze, x-y tilt, color preference, spectral tint preference, photochromic preference, ultra-violet coating preference, anti-reflective coating preference, or patient wear preference.
8. The method of claim 1 , wherein fabricating the correcting lens comprises curing a photosensitive component within the correcting lens.
9. The method of claim 1 , wherein:
(a) the matrix polymer comprises one or more polymer selected from the group consisting of a polyester, a polystyrene, a polyacrylate, a thiol-cured epoxy and a thiol-cured isocyanate and
(b) the monomer mixture comprises a thiol monomer and at least one monomer selected from the group consisting of an ene monomer and an yne monomer.
10. The method of claim 9 wherein the matrix polymer is a thiol-cured epoxy and the monomer mixture is a thiol monomer and an ene monomer.
11. The method of claim 9 wherein the matrix polymer is a thiol-cured epoxy and the monomer mixture is a thiol monomer and an yne monomer.
