"REGARD" - A new standard in contact lens solutions
Practitioners interested in fitting Silicone hydrogel lenses should visit the Silicone hydrogels.org website where several clinical papers are available. Lyndon Jones has written a short but interesting article suggesting that practitioners using new lens materials should seriously consider prescribing the latest contact lens solutions because there is growing evidence of issues relating to preservatives and these types of lenses. We simply ask all practitioners to ask themselves how much preservative is good for the eye? We believe none is the correct answer no matter what type of material used.
Developments in lens care solutions
Nick Atkins describes the evolution of current contact lens care solutions, explains their mode of action, and describes where incompatibility may affect performance
Regard - A multipurpose solution
An article introducing and explaining the unique properties of Regard.
Regard - A unique solution
This poster explains why Regard was developed and the mechanics of how this novel soft contact lens disinfection works.
Regard - Acanthamoeba Study
This poster shows the results of the study undertaken by Simon Kilvington, PhD, Department of Infection, Immunity & Inflammation, University of Leicester. This found Regard more effective at removing Acanthamoeba trophozoites and Cysts compared to Peroxide or preserved multi purpose solutions.
Regard - Ocular Safety Study
This poster displays the results of a study undertaken by Dr. med. O. Chr. Geyer to confirm the Ocular safety of soft contact lens disinfection with a stabilized, complexed Oxychlorite molecule.
Wet Therapy-Dry eye relief drops
The tear film is a continuously evolving, delicate structure, which covers and ensures the smoothness of the external surface of the eye. The tear film performs key visual functions, lubricates the space between the eyelid and eyeball, contributes to metabolism in the tissues it touches, collects and exchanges oxygen that is released to the epithelia on the surface of the eye. In addition, a number of substances important for corneal and conjunctival preservation - such as the epithelial growth factor, vitamins and ions that regulate epithelial maturation and growth reach the surface of the eye through the tear film.
In normal conditions, the tear fluid enjoys maximum stability and efficiency due to its dynamic nature and rich, variable solutes that change in concentration and absolute amount depending on the body,s requirement. A severely altered tear film results in dry eye syndromes and keratoconjunctivitis sicca. A pathological state is shown to frequently occur that is characterized by ocular discomfort and sometimes damaged surface of the eye, mainly related to a quantitative and qualitative deficit. Dry eye syndrome is often detected in wearers of contact lenses, especially hydrophilic lenses.
Important studies on the symptoms in contact lens wearers show that approximately 50% of them report symptoms attributable to lacrimal disorder. This condition results from increased evaporation of water from the tear film, decreased corneal sensitivity and moisture loss from the contact lens, which draws water from the tear fluid, thus removing it from the surface of the eye. Intact, plentiful tear film plays a major role in lubricating the front and back surfaces of contact lenses, which allows for good lens tolerance. Poor tear distribution may induce symptoms such as burning, feeling a foreign matter, conjunctival hyperemia and contact lens intolerance.
Ophthalmic solutions containing electrolytes have demonstrated efficacy in the treatment of dry eye(1, 2). Animal studies(1, 2, 3) have shown that a preservation of the equilibrium of the epithelial surface of the cornea is a critical factor in tear film stability(3). Experimental studies indicate that potassium is important in maintaining corneal thickness(1), while calcium and magnesium have a stabilizing role in the cellular adhesion mechanism. The latter two also appear to influence the permeability of the membrane, as well as mechanisms of cellular aggregation. An ophthalmic solution formulation which takes this into consideration could be help maintain and/or prevent pathological states related to the corneal surface/tear film interface(3).
This study aims at evaluating the subjective clinical effects and tolerability of a preservative-free, buffered Ph, isotonic solution containing sodium hyaluronate, polyethylene glycol and balanced mineral salt electrolytes (sodium, potassium,calcium and magnesium chlorites) All of the above ingredients are commonly used in ophthalmic solutions and free of bioincompatibility risks.
