Clinical performance of 'no rub' multi-purpose solutions.

This was a multi-site, 231-subject double-masked, bilateral crossover study to evaluate subjective comfort and satisfaction, corneal staining and lens deposits with two 'no rub' multi-purpose solutions (MPS) used with FDA Group II (alphafilcon A, SofLens 66, Bausch & Lomb) and Group IV (etafilcon A, SUREVUE, Johnson & Johnson Vision Care) soft contact lenses. Subjects used each of the two MPS, Regimen 1 (OPTI-FREE EXPRESS Multi-Purpose Disinfecting Solution No Rub Lasting Comfort Formula, Alcon Laboratories) and Regimen 2 (ReNu MultiPlus Multi-Purpose Solution, Bausch & Lomb), for 28 days. They wore the same lens type for the duration of the study and were evaluated on days 0, 14 and 28 of each treatment period.
