  • Patent number: 6737496
    Abstract: The present invention relates to photocurable siloxane polymers having functional acryl groups, useful in the preparation of intraocular lenses (IOLs). The polymers are siloxane copolymers, wherein the siloxane can be selected from the group consisting of diphenyl siloxane, phenylalkyl siloxane, dialkyl siloxane, and trifluoroalkyl alkyl siloxane. The invention also relates to methods for producing the said siloxane polymers, as well as to producing accommodating lenses in vivo, which means that the lens is formed in the capsular bag of the eye.

  • Publication number: 20040088050
    Abstract: The present invention discloses methods of obtaining ophthalmic lens capable of reducing the aberrations of the eye comprising the steps of characterizing at least one corneal surface as a mathematical model, calculating the resulting aberrations of said corneal surface(s) by employing said mathematical model, selecting the optical power of the intraocular lens. From this information, an ophthalmic lens is modeled so a wavefront arriving from an optical system comprising said lens and corneal model obtains reduced aberrations in the eye. Also disclosed are ophthalmic lenses as obtained by the methods which are capable reducing aberrations of the eye.

  • Patent number: 6361561
    Abstract: Polysiloxanes suitable for the preparation of intraocular lenses by a crosslinking reaction, having a specific gravity of greater than about 1.0, a refractive index suitable for restoring the refractive power of the natural crystalline lens and a viscosity suitable for injection through a standard cannula are provided. Moreover, injectable intraocular lens material based on these polysiloxanes and methods of preparing intraocular lenses by direct injection into the capsular bag of the eye are also disclosed.

  • Patent number: 5968095
    Abstract: A method of preoperatively selecting an intraocular lens to be implanted into an eye to postoperatively render the eye emmetropic or ametropic with a desired postoperative refraction comprises determining the location of the lens haptic plane of the eye, the corneal power of the eye and the axial length of the eye, choosing the desired postoperative refraction and assuming a lens to be implanted, the lens having a known power and geometry, including an offset between the lens haptic plane and an anterior vertex of the lens as if it was in its implanted state. With these parameters and refractive indices of the ocular fluids, a calculation is made to determine whether or not, postoperatively, focus will fall on the retina of the eye. If, from the calculation, it is determined that focus will not fall on the retina of the eye, another lens with a different power and/or geometry is assumed to be implanted and the calculation is repeated until the focus is calculated to fall on the retina of the eye.
