As optometry continues to evolve, it is critical for proactive practitioners to stay abreast of new developments that will help them provide improved clinical outcomes. This article highlights 10 new treatments in eye care that every optometrist should know.
1. Surface treatments
Tangible HydraPEG (THP; Tangible Science) is a relatively new surface treatment for gas permeable (GP) contact lenses. It has been available on SynergEyes Duette lenses, and it is present on the surface of Simplifeyes soft contact lenses. Plus, THP is available on most Optimum (Contamac) and Boston (Bausch + Lomb) materials.
THP is a polymer that encapsulates the lens, improving wettability of the surface through water retention. This increases the lubricity of the surface, providing a more comfortable wearing experience for the patient. Additionally, because the surface is hydrophilic, it repels lipid deposits on the surface of the lens.
With the benefits of this new coating, it is important to understand how these lenses need to be cared for because some of the rules for caring for GP lenses without THP do not apply. As an example, lenses coated with THP shouldn’t be cleaned with abrasive cleaners because such cleaners will strip the coating off of the lens. Five solutions are approved to be utilized for GP lenses with THP:
- Boston Simplus (Bausch + Lomb)
- Tangible Clean (Tanglible Science)
- Unique pH (Alcon),
- Clear Care (Alcon)
- Clear Care Plus (Alcon)
Some GP wearers have a habit of rinsing their lenses with water. Although this is not recommended with any GP lens, it is contraindicated for lenses with THP on their surface.
Soon, Tangible Science will launch Tangible Boost, a monthly soaking solution formulated to re-build the coating that may have naturally worn away over time with normal cleaning and conditioning of the lens.
