Is The Biocompatibles Proclear Lens Made Of A Material That Can Truly Benefit The Dry Eye Patient?

This study compared the Biocompatibles Proclear lens with the Ciba Focus lens, in their ability to allow a dry eye patient to wear soft contact lenses comfortably. This was a double blind pilot study with seven subjects wearing each lens for one week and then wearing the lens in opposite eyes for week two. Each patient completed a McMonnies questionnaire and objectively qualified as a dry eye patient through assessment of tear thinning time with a keratometric reading as well as using the Eyemap. Tear break up time, and slitlamp evaluation was also performed. Tear thinning time with a keratometer concentrated on
the central cornea, and TTT with the Topcon Eyemap revealed an overall corneal evaluation. Neither lens was identified objectively as a better lens for the dry eye patient. Subjective data obtained through a daily questionaire indicated 40% preferred proclear lens, 26% preferred the Focus lens and 33% had no preference.
