The present application discloses a method for three-dimensional deposition printing to manufacture optical elements including ophthalmic devices by controlling the level of oxygen in the polymerization mixture and the printing environment to achieve precision in form and smoothness of surface for image quality optical performance.

Three-dimensional printing of optical devices

Methods and apparatus for additive manufacture of an article corresponding with an energy transmissibility image. The article may include a contact lens or intraocular lens. The improvements are directed to repeated application of a monomer according to a pattern corresponding with the energy transmissibility image, such as grayscale image. The method may include intermittent pinning of deposited polymerizable mixture, partial cure, and final cure of the deposited polymerizable mixture. A pattern of multiple defined areas may be manufactured, with each area representing an amount of energy transmissibility associated with that area.

Polymeric additive manufacturing of an ophthalmic lens

Methods for additive manufacture of an article corresponding with one or more arrays of data values. The article may include, for example, an optical lens, such as a contact lens or an intraocular lens. The methods include generating an array of data values and emitting droplets of polymerizable mixture in a pattern corresponding with the arrays of data values. After receiving the droplets of polymerizable mixture on a receiving surface, the droplets are integrated and pinned via exposure to actinic conditions. Two or more patterns of droplets may be combined on the receiving surface to form a combined volume of polymerizable mixture and cured.

Additive manufacturing of an optical element

A multifocal ophthalmic lens with multiple sub-optical elements along a same optical path and methods for generating the multifocal ophthalmic lens. The method includes intermittent pinning of deposited polymerizable mixture and final cure of the deposited polymerizable mixture. The intermittent pinning may form a sub-optical element. A pattern of multiple defined areas may be manufactured, with each area representing an amount of energy transmissibility associated with that area. Each area may have a light value based upon a scale, such as an 8 bit, 16 bit, 32 bit, 64 bit scale or other scale. In some embodiments, each area may refer to a smallest single component of a digital image.
