ALK
The ALK RGP contact lens system has been developed with Alex Levit BSc FCOptom. This is a Keratoconus system that uses a relatively small (24 lens) trial set. This system uses a method of assessing the stage of advancement of the developing cone and has a range of lenses to fit different stages. These lenses feature a larger BCOD than other conventional Keratoconus lenses.
