A posterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible and permeable material. The lens has a generally circular optic and a plurality of integrally formed, filament-like haptics. The haptics project posteriorly from the optic and contain a raised feature or ridge that is sandwiched between the posterior iris and the zonules when implanted in an eye. Such a construction has a low vaulting force under compression, is size insensitive, provides for a stable lens once implanted in the eye, helps to avoid pupillary blockage and allows for improved aqueous flow around the natural lens.
