Thimerosal vs Benzalkonium Chloride A Study Of HGP Wetting Solutions.

My investigation was a side-by-side comparison study of a thimerosal and a benzalkonium chloride preserved hard gas permiable contact lens wetting solutions. My objective was to find if there was any significant difference between the two solutions. The patients were five Optometry Students who were successful HGP wearers. Each had worn his lenses for three months or longer and could comfortably wear his lenses ten hours a day or longer. ach was satisified
with his lenses and had no intention of changing to a different lens material
or going to full time spectacle wear.
