Solutions and Eye Supplements



There are generally two types of contact lens regime used for Soft Contact Lenses, namely the Hydrogen Peroxide System and the Multi-Purpose System. The following describes how the various contact lens solution systems should be used.

 

Hydrogen Peroxide Solution (H2O2) Systems

Surfactant Cleaners are first used to clean the surface of the lens to remove the trapped debris. This is done by rubbing the lenses in a circular motion of both the lens surface for a few minutes. The lenses are then placed into a lens case that comes with the Hydrogen Peroxide H2O2 disinfecting solutions. The H2O2 solution is then poured into the lens case, and the disinfection will commence.

Neutralization of the solution will be activated by either a “Platinum Ring” or insertion of a neutralizing tablet into the lens case (depending on brand of solution). The H2O2 solution will be neutralized into sterile water. It is advisable to rinse the lenses with saline prior to insertion of the lenses into the eye.

An enzyme tablet should be used with the solution to breakdown any proteins that are trapped on the lenses every weekly or fortnightly, depending on your contact lens practitioner’s advice. This system is generally used for conventional soft lenses, as protein deposits are very common in this type of lenses.

 

Multi-Purpose Solution Systems (MPS)

The contact lenses should be rubbed with the MPS on both sides for a few minutes. The lenses are then rinsed with the MPS and subsequently stored with fresh MPS solution. An enzyme tablet should be used with the solution to breakdown any proteins that are trapped on the lenses every weekly or fortnightly, depending on your contact lens practitioner’s advice.

Some MPS solutions are marketed as a no rub formula. However, your contact lens practitioner should advise on whether surface cleaning is necessary by physically examining your lenses on the microscope. This system is generally used for disposable soft lenses and Rigid Gas Permeable lenses.

 

Solutions for Rigid Gas Permeable (RGP) Lenses

Surfactant Cleaners that are meant for RGPs are used for surface cleaning. This is done by rubbing on both sides of the lenses for a few minutes. Subsequently, the lenses should be stored in conditioning solution. This will keep the lenses disinfected. Enzyme tablets/solutions should be added to the conditioning solution every weekly or fortnightly on the advise of your contact lens practitioner.

Alternatively, MPS that are meant for RGPs can be used to clean and disinfect the lenses. The MPS is used to rub the lenses, and subsequently also used to store the lenses. Enzyme tablets/solutions should also be used weekly/fortnightly.

 

NOTE: Please consult your Optometrist / Contact Lens Practitioner on your lens care solutions. Your eye care Optometrist / Contact Lens Practitioner will determine which type of lens care solution is more suitable for you.

WARNING: Never use soft contact lens solutions on RGP lenses or vise versa unless otherwise stated.
