Evaluation of In Vitro Wettability of Soft Contact Lenses Using Tear Supplements

Hiroko Iwashita et al.

Summary: The measured contact angles (CAs) on soft contact lenses (SCLs) were affected by the use of 2-MPC solutions and hyaluronate acid (HA), with silicone hydrogel SCLs showing higher CAs. The interaction between tear supplements and SCLs may vary based on ingredient agents, surface treatment of the lenses, and components of the supplements.

Impact of a low molecular weight hyaluronic acid derivative on contact lens wettability

Katsuhide Yamasaki et al.

Summary: The study found that the low molecular weight hyaluronic acid derivative was more readily absorbed by silicone hydrogel contact lenses and accumulated more over time compared to conventional hyaluronic acid. Multipurpose solutions containing the derivative increased lens hydrophilicity by decreasing contact angles, with this effect maintained over multiple cycles.

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

Micael Alves et al.

Summary: The study found that contact lens materials and lens care solutions underwent mutual changes after storage, likely linked to biochemical and biophysical interactions between components and the release of some polymer compounds. These findings offer valuable insights into the interaction between CL materials and LCS in clinical settings.

CLEAR-Contact lens wettability, cleaning, disinfection and interactions with tears

Mark Willcox et al.

Summary: Contact lens materials have undergone significant changes in the past 20 years with the introduction of silicone hydrogel materials. However, research is still needed to improve comfort, as the association between contact lens wettability and comfort is not clear. The interactions between lens materials, tear film, and disinfection solution play an important role in biocompatibility, but whether this can be altered to improve comfort remains debatable.

Could contact lens dryness discomfort symptoms sometimes have a neuropathic basis?

Charles W. McMonnies

Summary: Symptoms of dry discomfort in soft contact lens wearers can be exacerbated by tear dysfunction and lens-induced challenges to tear homeostasis, potentially leading to corneal nerve disturbances. Lid wiper neuropathy may also play a role in some cases of contact lens intolerance. Post-lens tear pool stagnation with increased concentrations of inflammatory mediators could contribute to corneal neuropathy, particularly when discomfort develops after successful wear. Esthesiometry and confocal microscopy may help diagnose contact lens-related corneal neuralgia in discontinued wearers.

Surface Testing of Dental Biomaterials-Determination of Contact Angle and Surface Free Energy

Aneta Liber-Knec et al.

Summary: This study characterized the surface properties of dental materials using contact angle measurements and surface free energy calculations. Results showed that surface wetting depended on material composition and storage conditions, with significant differences observed in contact angles and surface free energies of different materials.

Relationships between the material properties of silicone hydrogels: Desiccation, wettability and lubricity

Petar Borisov Eftimov et al.

Summary: Silicone hydrogels (SiHy) are composite matrices designed for contact lenses, with their properties such as hydration, wettability, and lubricity needing to be optimized for use on the ocular surface. Different SiHy materials show varying performances under desiccation/rehydration cycling, with wetting agents incorporated ones being more susceptible to extended drying. There is a strong correlation between the wettability and lubricity of SiHy after at least 4 hours of blink-like cycling, providing insights for the design of novel ophthalmic materials.
