The present invention relates to a kind of shape-memory polymer intraocular lens, its can have the refractive index more than 1.45, the Tg comprising end points between 10 DEG C to 60 DEG C, reflective minimum or no-reflection and in visible spectrum substantially 100% light transmission rate.Intraocular lens is then by roll-in at a temperature of the Tg higher than SMP material.Intraocular device is radially compressed to the diameter less than or equal to 1.8mm while maintaining temperature to be higher than Tg in mould.The intraocular lens that the wide otch insertions of 2mm are compressed that is less than in cornea, sclera or other anatomical structures can then be passed through.Crystalline lens can be inserted into by otch by pouch, ciliary groove or other intracavitary.SMP can substantially achieve the refractive index value more than or equal to 1.45. |
