    • What every optometrist shouldknow about prescribing the right solution for each contact lens patient
    • In recent times, we have seen the emergence of serious ocular infections and
    • In recent times, we have seen the emergence of serious ocular infections and resultant contact lens solution recalls.
    •  Fall2005 (CIBA VISION discontinues all lenscare products) Summer 2006 ( B&L recalls ReNu MoistureLoc) Fall 2006 ( AMO recalls Complete MoisturePlus) Winter 2006 ( B&L recall of ReNu MultiPlus)
    • ReNu recallBausch + Lomb company acknowledged that polymers in this particular lens solution formulation easily formed microbial films under certain conditions that resulted from poor patient compliance.
    • These conditions included: Topping off contact lenssolution not replacing the lens case regularly not closing the bottle top between uses
    • When fitting patients with contact lenses, optometrists utilize their expertise to choose lenses with attributes that willbest meet each patient’s vision and eye health needs.
    • Once the lens has been chosen, should practitioners go one step further and prescribe a contact lens solution?
    • A patient who: is not prescribed a contact lens solution receives no explanation as to why a certain solution is best
    • A patient who: is not prescribed a contact lens solution receives no explanation as to why a certain solution is bestmay resort to picking aproduct based solely on thesale price or availablecoupons.
    • Shortcuts and ways to “save” solution or extend contact lens wear are common, even among our best patients.
    • To underscore the importance of theirrecommendation, optometrist should write solution recommendations on a prescription pad
    • There are two types of contact lens care systems:
    • There are two types of contact lens care systems: multipurpose contact lens solutions (MPS) hydrogenperoxide-based care systems(HPB)
    • Multipurpose contact lens solutions are dual- purpose liquids : Clean disinfect
    • Multipurpose solutions also are called "no- rub" solutions:because they are designed to adequately clean and disinfect lenses with a simple rinse-and-store method, eliminating the need to mechanically rub the lenses to remove lens deposits.
    • many eye care professionals recommendadding a short, 10-second period ofmechanical rubbing as part of thecleaning regimen with multipurposesolutions.
    •  less expensive easier to use than hydrogen peroxide- based solutions,  therefore contact lens wearers are more likely to use multipurpose solutions properly
    • recent years there has been a global recallof at least one brand of a multipurposecontact lens solution because of anoutbreak of fungal eye infections associatedwith the product
    •  thepreservatives(varying molecular weights) Wettingagents(harbor opportunistic microbes) challengeof cleaning and disinfecting the newest contact lens material: silicone hydrogel.
    •  provide effective lens disinfection noproduct recalls have occurred due to outbreaks of eye infections. low amounts of corneal staining
    •  one-step two-step process
    • Both one-step and two-step HPB lens care systems after lens disinfection and prior to wearing the lensesrequire neutralization of the hydrogen peroxide solution.
    • because hydrogen peroxide is an effective disinfecting agent,
    • because hydrogen peroxide is an effective disinfecting agent,but it is toxic to the cornea and must be converted to saline with a neutralizing agent to avoid eye injury.
    •  the lenses are placed in a holder within a cylindrical contact lens case. the case is filled with a 3 percent solution of hydrogen peroxide. The bottom of the case contains a solid disk of a material that immediately begins neutralizing the hydrogen peroxide.
    •  the contact lens are placed in a lens case filled with only the hydrogen peroxide for a specified period of timeA neutralizer is then added to the case to convert the disinfectant to harmless saline
    • Hydrogen peroxide care systems arepreservative-free and therefore are often recommended for contact lens wearers who :
    • Hydrogen peroxide care systems are preservative-free and therefore are often recommended for contact lens wearers who :may be sensitive to preservatives found in multipurpose contact lens solutions
    •  one-stepHPB:may not expose contacts to full-strength hydrogen peroxide for an adequate period of time
    •  one-stepHPB:may not expose contacts to full-strength hydrogen peroxide for an adequate period of time two-step HPB :users will forget the neutralizing step and incur a painful eye injury
    • Opti-Free RepleniSH (Alcon) and Clear Care (CIBA Vision)Clear Care could provide longer wear times than the other MPS system
    • Biotrue inspired by the biology of the eye to make wearing contact lenses easie. pH in the range of healthy tears keep lenses moist for up to 20 hours can be used with all soft and silicone hydrogel lenses. Keeps beneficial tear proteins alive
    •  renu® fresh renu sensitive(will soon be available in a convenient clear bottle, and both the carton and bottle are 100% recyclable)
    • AQuify® 2004 PRO-GUARD™ lens case.(reduce lens case contamination when used with Aquify) ideal for patients that wear their lenses for extended periods during the day.
    • Clear Care 2001 one bottle 3% hydrogen peroxide solution kills bacteria and germs The bottle is marked with a red tip( caution patients from directly putting in their eyes.)
    • OPTI-FREE® RepleniSH 2006: provide a high level of moisture for patients wearing all types of contact lenses Wettingagent -TearGlyde® formulation( provides the lenses with a layer of moisture all day)
    • OPTI-FREE PureMoist Wetting agent -HydraGlyde® Moisture Matrix( surrounds lenses in a cushion of moisture to keep contacts hydrated) dual disinfectants POLYQUAD® and ALDOX can also be used for sensitive eyes reduceslipid deposition and removes protein deposits.
    •  RevitaLens OcuTec - 2010 combines the disinfection of a peroxide system with the convenience of a multi-purpose solution OcuTec- antimicrobial activity even under non-compliant conditions -a high effectiveness against Acanthamoeba (single- celled living organism)
    • - low rates of corneal staining and adverse effects- - effective protein removal leading to tolerability less redness less end of day dryness
    • Oxysept hydrogen peroxide disinfection solution/neutralizer Neutralized Oxysept is also nearly identical to natural tears (viscosity and surface tension) the neutralizing tablet eliminates the risk of residual peroxide a natural B12 color has been added ideal for sensitive eyes
