Optics and Aberrations

Navigating the Impact of Preservatives in Ophthalmic Medications: Insights From Dr. Robert J. Noecker

In this episode, Robert J. Noecker, MD, reviews the role of preservatives, particularly benzalkonium chloride (BAK), in ophthalmic medications. While BAK effectively prevents bacterial growth, its inherent toxicity poses challenges with prolonged use, leading to symptoms associated with ocular surface diseases. Dr. Noecker emphasizes the importance of exploring alternatives like preservative-free formulations or less toxic oxidizing preservatives, which should ensure effective glaucoma treatment without compromising ocular health.

The European Approach to Preservative-Free Pharmaceuticals: A Conversation With Dr. Anton Hommer

In this episode, Anton Hommer, MD, discusses the European perspective on adopting preservative-free pharmaceuticals, highlighting challenges like health care professionals’ reluctancy to change, diverse reimbursement systems, and higher costs. He compares single-use and multiuse drugs, considering factors such as environmental impact and cost-effectiveness. Dr. Hommer emphasizes the superior efficacy of preservative-free medications, especially in treating chronic conditions such as glaucoma, and anticipates an increase in their use to protect ocular health and enhance chronic disease management.
