Hypothesis
What is the composition of the protein deposition proteome associated with silicone hydrogel contact lenses and care solutions?
Conclusion
Silicone hydrogel lenses have significantly less protein deposition compared to traditional soft lenses, with a consistent proteome across different materials.
Supporting Evidence
- 19 unique proteins were identified across the two lens materials.
- Lotrafilcon B was associated with more proteins than galyfilcon A.
- Six proteins were consistently found across all lens-solution combinations.
Takeaway
This study looked at what proteins stick to contact lenses and found that silicone lenses collect much less protein than older types of lenses.
Methodology
A randomized, controlled, examiner-masked crossover clinical trial was conducted with participants wearing different lens-solution combinations.
Limitations
The study did not account for the potential impact of lens rinsing on protein observation.
Participant Demographics
Participants were required to be 18 years or older, with healthy eyes and specific refractive errors.
