KEY TAKEAWAY POINTS

The PRECISION PROFILE^® Design on Alcon multifocal contact lenses is a center-near aspheric design with a smooth power profile, changing continuously from the center of the lens to the periphery of the optic zone.

Literature does not support basing multifocal optic zone designs on pupil size relative to refractive error or age.

Alcon multifocal contact lenses with the PRECISION PROFILE^® Design are pupil size independent, and clinical data has demonstrated that pupil size did not affect visual performance or the number of lenses required for a proper lens fitting.

The PRECISION PROFILE^® Design makes Alcon multifocal contact lenses easy to fit and allows for a 96% success rate using two lenses or less per eye (at the initial visit) with a simple 2-step fitting process.

Using a new, same day manifest refraction that maximizes plus for distance and minimizes ADD power is critically important for a successful initial lens fit.

Automatically adding +0.25D to the vertexed distance manifest refraction before picking the initial trial lens and then starting the contact lens over-refraction with +0.25 will help ensure the distance power is maximized for plus.
