Contact Lens Products
maintain contact lenses include the following:
Disinfectant Solutions: These preparations destroy germs (bacterial, viral and fungal) to prevent infections. Two preparations are available: hydrogen peroxide and chemical. Because hydrogen peroxide can irritate the eye, lenses disinfected with it require follow-up bathing with a neutralizer. Chemical formulations do not require a neutralizer. Brand names and ingredients: Aosept Disinfection System (sterile ophthalmic solution, microfiltered hydrogen peroxide, sodium chloride, phosphonic acid, phosphates). Ultracare Disinfecting Solution/Neutralizer (hydrogen peroxide, sodium stannate, sodium nitrate; buffered with phosphates, purified water, catalase, hydroxypropyl methylcellulose, vitamin b12). Opti-Free One-Step Cleaning & Disinfecting Tablets (pancreatin derived from highly purified pork).
Neutralizers: These preparations (solutions and sometimes tablets) are used on lenses disinfected with hydrogen peroxide. They turn the peroxide into harmless oxygen and water. Brand name and ingredients: Ultracare Disinfecting Solution/Neutralizer (hydrogen peroxide, sodium stannate, sodium nitrate; buffered with phosphates, purified water, catalase, hydroxypropyl methylcellulose, vitamin b12).
Saline Solutions: These are sterile salt solutions used to rinse away other solutions. They also may be used to store lenses and to clean lenses in a heating system. Brand names and ingredients: Bausch & Lomb Sterile Preserved Saline Solution (boric acid, sodium chloride, thimerosal, edetate disodium). CIBA Vision Saline Solution (sodium chloride, boric acid, sodium borate).
Soaking Solutions: These preparations restore moisture in lenses. Some solutions perform the additional function of disinfecting lenses. Brand names and ingredients: Sereine Wetting and Soaking Solution for Contact Lenses (buffers, sodium chloride, a polyoxypropylene -polyoxyethylene copolymer, disodium EDTA, benzalkonium chloride). Barnes Hind Wetting & Soaking Solution (octylphenoxy ethanol, povidone, polyvinyl alcohol, propylene glycol, sodium chloride, hydroxyethylcellulose, edetate disodium, chlorhexidine gluconate)
Enzyme Preparations: These preparations are weekly-use tablets or solutions that remove stubborn protein buildup on lenses. They can lengthen the useful life of lenses. Some lenses require disinfection after an enzyme cleaning. "Planned-replacement lenses" (lenses replaced at frequent intervals) usually do not require enzyme cleansing because they are replaced before protein builds up to troublesome levels. Brand names and ingredients: Complete Weekly Enzymatic Cleaner for Soft Contact Lenses (subtilisin A). Opti-Free Enzymatic Cleaner (pancreatin). Boston One Step Liquid Enzymatic Cleaner (proteolytic enzyme, glycerol).
Wetting Solutions: These preparations for hard and RGP lenses create a cushion between the eye and the lens and improve comfort. Brand names: Liquifilm Wetting Solution for Comfortable Hard Contact Lens (polyvinyl alcohol with hydroxypropyl methylcellulose, edetate disodium, sodium chloride, benzalkonium chloride). Barnes Hind Wetting & Soaking Solution (octylphenoxy ethanol, povidone, polyvinyl alcohol, propylene glycol, sodium chloride, hydroxyethylcellulose, edetate disodium, chlorhexidine gluconate).
Rewetting Solutions: These preparations moisten lenses while they are still in the eye. Brand names and ingredients: Boston Rewetting Drops (cationic cellulose derivative polymer, polyvinyl alcohol, hydroxyethylcellulose, chlorhexidine gluconate, edetate disodium. Opti-Free Rewetting Drops for Disposable Soft Contact Lenses (citrate buffer, sodium chloride, edetate disodium, polyquaternium-1).
Combination Preparations: These products perform several functions. For example, some kits are used for cleaning, wetting and soaking; others are used for disinfecting, rinsing and storing.
