If a patient is experiencing dry eyes while using contact lenses, which type of lens might be recommended?

Silicone hydrogel lenses are often recommended for patients experiencing dry eyes while using contact lenses due to their superior oxygen permeability compared to traditional hydrogel lenses. This increased oxygen transmission helps maintain corneal health and minimizes dryness by allowing more moisture to reach the eye. Silicone hydrogel materials also tend to retain less water than older hydrogel materials, which can lead to reduced sensitivity to drying out.

Additionally, silicone hydrogel lenses often include moisture-retaining technologies and are available with various surface treatments that can enhance comfort for dry eye patients. The combination of these factors makes them a suitable choice for individuals who struggle with dryness, as they help to create a more comfortable wearing experience throughout the day.

Daily disposable lenses, while convenient and beneficial for reducing the risk of contact lens-related complications, might not always address the underlying issues of dryness, as patients are exposed to a fresh lens daily but may still experience symptoms. Rigid gas permeable lenses can provide excellent vision correction but may not always be the best choice for comfort in those with dry eyes. Weekly replacement lenses can also offer benefits, but they may not provide the same level of oxygen permeability or moisture retention as silicone hydrogel lenses, making them a less ideal option for patients specifically facing dryness.
