Extended contact lens wear has long been thought to be the most desirable modality for our patients because it offers great convenience, uninterrupted good vision and suits those with an active lifestyle. Despite these benefits, extended wear is not prescribed with any frequency in the United States—at least not since the late 1980s, when researchers found a much higher incidence of ulcerative keratitis with this modality compared with daily wear.
While a few extended wear contact lens options remain on the market, many uncertainties hinder their use, including concerns that not enough oxygen passes through the lens to support a healthy cornea or that a toxic tear film exists beneath a contact lens that needs to be flushed by removing the lens. In addition, a practitioner’s history of contact lens patients with microbial keratitis or inflammation may lead them to prescribe a more limited wearing time. This article takes a look at extended wear today, how advances have improved the modality and what questions remain.
Red eyes are relatively common in practice but not always straightforward, and adding a contact lens to the ocular surface only complicates things. To avoid potentially vision-threatening scenarios, practitioners need to come up with a timely, appropriate diagnosis and treatment plan. This article discusses how to streamline these processes for contact lens-related red eyes to achieve the best possible outcome.
An estimated 2.2 million Americans have glaucoma and 20 million have dry eye disease (DED)—odds are, practitioners are bound to see patients diagnosed with both. Research suggests the comorbidity of DED in patients treated topically for ocular hypertension and glaucoma could be as high as 20% to 59%. But few step back to consider the association between these two chronic and progressive diseases.
Often, it’s nearly impossible to decipher which disease came first and how much of the DED is iatrogenic—caused inadvertently by a medical treatment or procedure. With each additional medication involved in the treatment of glaucoma, the risk of an adverse event or possible exacerbation of dry eye multiplies. Here’s a look at the ocular surface in patients being treated for glaucoma—and how you can help protect it.
