INTRAOCULAR LENSES HAVING AN ANTERIOR-BIASED OPTICAL DESIGN

INTRAOCULAR LENSES HAVING AN ANTERIOR-BIASED OPTICAL DESIGN

An ophthalmic lens includes an optic having an anterior surface with an anterior surface radius of curvature (R1) and a posterior surface with a posterior surface radius of curvature (R2). The anterior surface radius of curvature (R1) and the posterior surface radius of curvature (R2) define a shape...

description An ophthalmic lens includes an optic having an anterior surface with an anterior surface radius of curvature (R1) and a posterior surface with a posterior surface radius of curvature (R2). The anterior surface radius of curvature (R1) and the posterior surface radius of curvature (R2) define a shape factor (X) (where X=(R2−R1)/(R2+R1)) that is greater than zero. The shape factor (X) corresponds to a curve defining shape factor (X) as a function of lens power (P), the curve monotonically decreasing with increased lens power (P).
