摘要:
An intraocular lens system comprising: an anterior light-converging intraocular lens (16) for positioning within the eye, the anterior lens having an anterior surface and a posterior surface; and a posterior light-diverging intraocular lens (17) for positioning within the eye posterior to the anterior lens, the posterior lens having an anterior surface and a posterior surface; wherein the posterior lens is separate to the anterior lens; and wherein at least one of the surfaces of the anterior lens or surfaces of the posterior lens is a modified surface which includes a surface aberration which increases the depth of focus of the lens, optimises image quality and may also provide for a magnified image over a range of retinal eccentricities.
