Title:
SHAPE MEMORY POLYMER INTRAOCULAR LENSES
Document Type and Number:
WIPO Patent Application WO/2012/122320
Kind Code:
A3
Abstract:
A shape memory polymer (SMP) intraocular lens may have a refractive index above 1.45, a Tg between 10 C and 60 C, inclusive, de minimis or an absence of glistening, and substantially 100% transmissivity of light in the visible spectrum. The intraocular lens is then rolled at a temperature above Tg of the SMP material. The intraocular device is radially compressed within a die to a diameter of less than or equal to 1.8 mm while maintaining the temperature above Tg. The compressed intraocular lens device may be inserted through an incision less than 2 mm wide in a cornea or sclera or other anatomical structure. The lens can be inserted into the capsular bag, the ciliary sulcus, or other cavity through the incision. The SMP can substantially achieve refractive index values of greater than or equal to 1.45.
