Contact Lens Care & Compliance

Research From the 2011 AAO Annual Meeting

By Susan J. Gromacki, OD, MS, FAAO

There has been a proliferation of research this year on lens care and compliance, as evidenced by the Scientific Program of the American Academy of Optometry's annual meeting. Here is a summary, with industry sponsorship, if applicable. For details on presentations, visit www.aaopt.org and select the "Archives" tab.

• Impact of CL disinfecting solutions on the native state of a tear film protein (Bausch + Lomb [B+L])
• Physical properties of CL disinfecting solutions (B+L)
• Evaluation of the impact of contact lens care solutions on the tear film lipid layer
• Quantitative association between MPS preservative agents and ophthalmic dyes (B+L)
• Retention and release of the wetting agent combination found in a novel multipurpose solution from hydrogel and silicone hydrogel contact lenses (B+L)
• Comparing contact lens compliance and complications in a university clinic with private optometry offices (Alcon)
• Comparison of patient compliance with replacement intervals between 2-week and 1-month soft lens wearers in an urban academic clinic environment
