  Purpose

The principal aim of this project is to determine the time course of development of contact lens and contact lens case contamination during daily wear of silicone hydrogel lenses. The secondary aim of the study is to determine whether the time course of development of contact lens and contact lens case contamination varies between two different contact lens care systems.

Criteria

Inclusion Criteria:

  • Distance contact lens prescription between +8.00 and -10.00D.
  • Cylindrical component of refractive error no greater than 1.25D in either eye.
