4 Extended wear, noncompliance, and poor lens hygiene increase the chances of a fungal infection. Although patient noncompliance may be partially responsible in these two outbreaks, it is also believed that the disinfection efficacy of these two solutions was decreased, part of the formulation facilitated the pathogen growth, and the solution caused disruption to the corneal surface creating a portal for the infection to occur. Chemical care regimens have been removed from the market because of cases of Fusarium (ReNu MoistureLoc) and Acanthamoeba (Complete Moisture Plus) that were linked to the use of these solutions. If in doubt, changing the patient to a nonpreserved care regimen or a daily disposable contact lens modality may eliminate the symptoms.Īdditionally, the preservatives in chemical care regimens are not as effective against bacteria, fungi, and Acanthamoeba as hydrogen peroxide care regimens. 3 Although the sensitivity rate may be lower with the newer preservatives, the practitioner needs to be aware that symptoms of sensitivity to them may be delayed and somewhat vague. The three chemical care regimens resulted in inducing more corneal staining to a small extent in the Staining Grid study and even more in the IER Matrix study. Both studies found a hydrogen peroxide care regimen (ClearCare, Ciba Vision) to perform well with four silicone hydrogel materials (Acuvue Advance & Acuvue Oasys, Vistakon O 2Optix, Ciba Vision and PureVision, Bausch & Lomb). The IER study investigators looked for the presence of staining three times over a 3-month period. In the Staining Grid study, staining was assessed after 2 hours of wear and overnight soaking. 2 The Andrasko Staining Grid and the Institute for Eye Research (IER) Matrix both pertained to solution-induced corneal staining. A study with adolescents found that overall, patients on a hydrogen peroxide system show less staining and inflammatory response than those patients using a chemical care regimen. Changing the patient to a preservative-free, hydrogen peroxide care regimen alleviates the dry-eye symptoms. 1 The soft contact lens wearer using a multipurpose chemical solution presents with normal external findings, but complains of ocular dryness. A condition called multipurpose nonkeratitis has been reported. Occasionally, some patients may stillĮxhibit sensitivity, reporting symptoms of dryness, itching, burning, injection, decreased wearing time, and discomfort. The preservatives currently used cause less patient sensitivity. Although both of these preservatives exhibit excellent preservative action, many patients were sensitive to them. Check the absence of contraindications by the ophthalmologist.The problem that originally became apparent with chemical disinfection systems was the use of preservatives, such as thimerosal and chlorhexidine. Read the warnings and instructions for use carefully. The absence of preservatives makes the solution suitable for even the most sensitive eyes. In addition, the Poloxamer detergent present in the solution performs an additional cleaning without the need to rub. With Ciba Vision's AOsept Plus, the disinfectant action of peroxide, combined with effervescence, detaches and removes microorganisms (which can cause infections) and proteins. AOSept Plus also contains a surface cleaner, so disinfection and cleaning take place at the same time. Although it can be used with all types of soft and semi-rigid contact lenses, it is particularly recommended for silicone hydrogel lenses.
