Alternatively, lithography can be used to print marks or a pattern on one or both surfaces of the lens (e.g. grid, rings, matrix) to cause light diffraction to make a diffractive lens optic, or lithography combined with etching (e.g. lens mold surface) can be used to make nanometer to angstrom dimension profiles, protrusions, patterns, contours on lens surfaces to provide multi-focal and/or defractive lens surfaces.

(207) An accommodating artificial ocular lens (AAOL) device can be configured to both tilt the lens optic portion and laterally shift the center of the lens optic portion in some applications by combining the features described above.
(208) To make the custom accommodating artificial ocular lens (AAOL) device according to the present invention, the patient's eye must be carefully analyzed, measured and mapped to determine the specifications of the accommodating artificial ocular lens (AAOL) device to be manufactured. Specifically, the following is a list of specifications of the accommodating artificial ocular lens (AAOL) device to be considered and then specified, including but not limited to:

(231) At the eye surgeon's office, the patient's eye is measured using visual field analyzers, eye charts and a topographer/abberometer. The abberometer measures the aberrations in the patient's eye and provides the eye surgeon with a topography map outlining all the aberrations. The eye surgeon uses the abberometer to check where the aberrations are coming from and analyze the data for different pathologies and make changes to the data where necessary. The abberometer is then used to generate a topography map and digital data that will be transferred to the manufacturer in the form of a customized lens order via satellite, internet, telephonic down load, CD ROM, DVD or mail or fax. Abberometer obtains the necessary information by using the Shack Hartman or means, which analyzes multiple beams of light transferred to the retina and then returned back through the eye. Variations of the light are measured against a light standard that would give perfect vision if all the parameters are met. The variation of the light is then compared against the Zerkeny polynomial to determine whether the variations are in the form of low order aberrations usually spherical and cylinder (toric) or high order aberrations such coma; trefoil (shapes showing in the optic system that look like a starburst usually around the periphery of the eye extending toward the center.
(232) This information will then be received by the manufacturer, analyzed for completeness and any other kind of transmission errors. The data received is in the form of data points to be run through a program that to invert or reverse the information, since to correct an optic system requires making points or corrections that are opposite of the actual data received. This data will be run through the program to convert the data converted into machine language that will form a JFL file that will tell any equipment that can have varying cut (the Presitech Optiform with a variable forming tools or the DAC system with its toric generator) to cut a mold pin or optic in a form based on the information received from the eye surgeon's topography/abberometer, Zydekia Chart etc.
(233) The order depending on the method of manufacturing can create a lens optic as part of the shop order or create a mold pin for the shop order in case of silicone manufacturing. The shop order would then go through the manufacturing process for developing lenses and a final lens optic would be made. During the process the lens would be marked in a manner so that the eye surgeon doing the surgery can tell where on the lens optic the changes are made. One side of the optic can contain all the changes needed for a multi-focal, toric and/or wavefront corrections, or some changes can be on the front side and some on the back side of the accommodating artificial ocular lens (AAOL) device depending on the patient and manufacturing constraints. In order to know that what was manufactured is what was ordered, similar equipment would be used to generate the data such as an abberometer using the same theoretical method to measure the reverse aberrations created in the lens and compare it with the original input information. The accommodating artificial ocular lens (AAOL) device is then sterilized and sent to the eye surgeon.
(234) The manufactured lens data can be sent back with the lens to the eye surgeon, including data points and topography map with a manufacturing certificate for the eye surgeon and patient similar to a patient ID card, instead it would have a topography of the lens on the card.
(235) The eye surgeon then inserts the lens haptic and lens optic into the patient's eye and places the accommodating artificial ocular lens (AAOL) device where needed based on what was ordered received. Minor adjustments in the lens optic and lens haptic can be made to obtain the appropriate axis of the optic. It is possible to make and optic off center in a mold pin combination if it were determined up front exactly where and if the optic needed to be changed from its center point. It is also possible to put adjustments items on the optic and haptic whereby the optic could be shifted up, down or side ways so that the multi-focal, toric, wave front can be lined up to give the patient better vision.
Lens Operation
(236) The accommodating artificial ocular lens (AAOL) device according to the present invention is configured to bow or flex due to forces applied by the eye to the accommodating artificial ocular lens (AAOL) device, in particular to forces applied to the edge portions of the lens plate haptic portion.
(237) The accommodating artificial ocular lens (AAOL) device according to the present invention can be located potentially in the anterior chamber and/or posterior chamber of the eye. Preferably the accommodating artificial ocular lens (AAOL) device according to the present invention in located in the posterior chamber of they eye, and more preferably is located in the capsular bag of the eye after cataract lens removal.
(238) In operation, forces that are exerted on the capsular bag by the zonules of the eye are applied to the accommodating artificial ocular lens (AAOL) device according to the present invention, in particular to the peripheral edges thereof. As forces are applied to the outer edges of the accommodating artificial ocular lens (AAOL) device according to the present invention by the eye, the lens plate haptic portion begins to bow in an arch generally perpendicular to the flexible or resilient lens arm portions connecting the lens optic portion to the lens plate haptic portion so as to move the lens optic portion either forward or rearward from a resting position depending on the particular configuration and arrangement. In any event, the accommodating artificial ocular lens (AAOL) device according to the present invention is configured so that the lens plate haptic portion moves the lens optic portion during operation.
