5 Key Takeaways
-
1
Polyethylene glycol (PEG) is valued in ophthalmology for its low immunogenicity and biocompatibility, enhancing contact lens performance.
-
2
PEG coatings improve wettability and reduce protein deposition on contact lenses, enhancing patient comfort and reducing dry eye symptoms.
-
3
Tribranched PEG outperforms linear PEG in improving lens wettability and protein resistance, providing better surface coverage.
-
4
Patients wearing PEG-coated scleral lenses report significant improvements in comfort and dry eye symptoms compared to uncoated lenses.
-
5
Initial adaptation comfort for novice wearers of rigid lenses is not improved by PEG coatings, indicating limitations in their effectiveness.
