POLYMER MATERIAL AND INTRAOCULAR LENS
A polymer material is provided that can be used to produce an intraocular lens having a high refractive index and low adhesion on a lens surface and suppressing the occurrence of glistening and sub-surface nano glistening. Further, an intraocular lens with the properties mentioned above is provided. The polymer material can preferably be used to produce an intraocular lens. The polymer material is formed by polymerizing a liquid monomer mixture containing 11 to 30% by mass of a macromonomer (A) represented by the following formula (I) and at least a (meth)acrylate monomer (B) with an aryl group.
##STR00001##
[In the formula, four n respectively and individually representing 1 or 2, a, b, c, and d being respectively and individually integers of 4 or more, and four Z being respectively and individually substituent groups containing a (meth)acryloyl group.]
Polymers and methods for ophthalmic applications
Novel methods and materials particularly useful for ophthalmic applications and to methods for making and using the same are disclosed herein. More particularly, relatively soft, optically transparent, foldable, high refractive index materials particularly suited for use in the production of intraocular lenses, contact lenses, and other ocular implants and to methods for manufacturing and implanting IOLs made therefrom are disclosed.
COMPOSITE LIGHT ADJUSTABLE INTRAOCULAR LENS WITH DIFFRACTIVE STRUCTURE
A composite light adjustable intraocular lens comprises an acrylic diffractive intraocular lens, having a diffractive structure and haptics; and a silicone light adjustable lens, attached to the acrylic diffractive intraocular lens. The diffractive structure produces constructive interference in at least four consecutive diffractive orders corresponding a range of vision between near and distance vision, wherein the constructive interference produces a near focal point, a distance focal point corresponding to the base power of the ophthalmic lens, and an intermediate focal point between the near focal point and the distance focal point and wherein a diffraction efficiency of at least one of the diffractive orders is suppressed to less than ten percent.
OPTICAL IMPLANT AND METHODS OF IMPLANTATION
An apparatus has central lens body for providing vision correction for a patient. The lens body has a central aperture and is configured as one of: a diffractive lens or a refractive lens.
Blocking element of short wavelengths in LED-type light sources
Method, product and blocking element of short wavelengths in LED-type light sources consisting of a substrate with a pigment distributed on its surface and, in that said pigment has an optical density such that it allows the selective absorption of short wavelengths between 380 nm and 500 nm in a range between 1 and 99 %.
LIGHT ADJUSTABLE INTRAOCULAR LENS WITH A MODULABLE ABSORPTION FRONT PROTECTION LAYER
Embodiments of a modulable absorption light adjustable lens (MALAL) comprise a light adjustable lens that is capable of changing its optical properties upon an adjusting irradiation, including a photo-modifiable material; and a modulable absorption front protection layer, including a modulable absorption compound whose absorption properties can be modulated with a modulating stimulus. Other embodiments include a method of adjusting an optical property of a modulable absorption light adjustable lens, the method comprising: reducing an absorption of a modulable absorption compound of a modulable absorption front protection layer of the MALAL by a modulating stimulus, the MALAL having been previously implanted into an eye; and changing an optical property of a light adjustable lens of the MALAL by applying an adjusting irradiation.
HIGH REFRACTIVE INDEX, HIGH ABBE NUMBER INTRAOCULAR LENS MATERIALS
Disclosed are high refractive index, hydrophobic, acrylic materials. These materials have both high refractive index and a high Abbe number. This combination means the materials have a low refractive index dispersion and thus are especially suitable for use as intraocular lens materials. The materials are also suitable for use in other implantable ophthalmic devices, such as keratoprostheses, corneal rings, corneal implants, and corneal inlays.
