Interactions between contact lenses and lens care solutions: Influence in optical properties

Influence of Selected Ophthalmic Fluids on the Wettability and Hydration of Hydrogel and Silicone Hydrogel Contact Lenses—In Vitro Study

“…Alves et al [69] investigated the interaction between contact lenses and the CLS. In their work, they suggest that the optical variables of CLS and contact lenses themselves changed after storage.…”

The pH-induced physical properties of ionic contact lens material

“…Previous studies mainly studied the state of water that varies depending on the type and/or ratio of polymer and additive [ 26 , 28 , 29 ]. When the developed materials are applied to ocular surface or immersed in contact lens care solutions or eye drops, the content of state of water could be changed and affect various physical properties including not only diameter, refractive power that examined in this study but also oxygen permissibility [ 30 , 31 , 32 ]. In addition, this study only includes conventional hydrogel contact lenses while the most prescribed or used are silicon hydrogel contact lenses [ 33 ].…”

Letter to the Editor Concerning “Common Ophthalmic Preservatives in Soft Contact Lens Care Products: Benefits, Complications, and a Comparison to Non-Preserved Solutions” [Letter]

“… 3 , 4 This can potentially elicit a corneal response. 3 As mentioned in the article, the combination of ingredients in a solution and the combination of a solution with a particular lens material may be pertinent to the development of corneal staining, or, as discussed in Alves et al, 5 affect the optical properties of the lens. While it may not directly be a result exclusively of the preservative in the MPS and also associated with biochemical and biophysical interactions, the H2O2 product was more resistant to change when combined with a variety of materials.…”

“…While it may not directly be a result exclusively of the preservative in the MPS and also associated with biochemical and biophysical interactions, the H2O2 product was more resistant to change when combined with a variety of materials. 5 Though these influences have not yet been examined in the scleral lens environment, they may or may not have clinical importance there as well. These considerations should evoke careful deliberation weighing the pros and cons carefully pending a recommendation to use an MPS with scleral lenses.…”
