Contact Lens Update

Immobility of a lens on the eye – often observed immediately on eye opening after sleep with silicone hydrogel lenses. Normal movement patterns are gradually established after eye opening so that binding is usually not observed at an aftercare visit. Binding might occur when the aqueous layer of the post-lens tear film is decreased over night, leaving the tear film viscous and adhesive.
Lens adherence is also observed in poor fitting RGPs.
