Care System Versus Transmitted Light Wavefront Pattern of Contact Lenses

Abstract: In addition to disinfection ability and ocular surface reactions, CL care systems are different in solution-related CL optical performance. Multipurpose solutions may affect the CL surface morphology with significant modifications of the transmitted light wavefront pattern.

“…In contrast, another study found patients disinfecting SiHy soft contact lenses with a hydrogen peroxide-based system had worsening external eye conditions and tear film instability [350]. Combinations of lens material and care solutions can result in changes to the material properties of contact lenses, which may in turn change clinical performance [351][352][353]. For example, after exposure to hydrogen peroxide the elastic modulus of lotrafilcon B reduced, but increased for comfilcon A [353].…”

“…The use of MPDS with SiHy contact lenses has been reported to induce significant detrimental changes in optical quality in comparison to lenses treated with hydrogen peroxide, which may be attributed to changes in the contact lens's surface [351], including modifications in surface roughness and in the refractive index of the contact lens [352].…”

“…There is experimental evidence of relaxation and swelling of the polymeric network close to the CL surface when the materials are exposed to LCS [23]. The latter study detected changes caused by MPS in the morphology of CL surface, which was more wrinkled, together with changes in CL optical properties, with variations of the Zernike coefficients.…”

“…Nowadays, there is evidence that uptake and release of lens care solutions (LCS) components in CL materials may occur [21]. Differences in physical properties of solutions have been reported [22] that can induce different changes in CL properties, including from an optical point of view [23] or in their physical dimensions [24]. The main optical characteristics of contact lenses are related to its transparency and the ability to block ultraviolet radiation (UVR).…”

“…Previously, the Ultracare Disinfecting System (Allergan, Irvine CA; now Johnson and Johnson Vision Care) was found to alter balafilcon A (PureVision, Bausch and Lomb) lens dimensions (Bausch & Lomb PureVision®, ; Snyder, ). Chiericati and colleagues reported changes in light transmission after 30 disinfection cycles of three silicone hydrogel lens models using two lens care solutions,(Chiericati et al, ) which the authors attributed to MPS‐mediated changes in lens surface morphology.…”
