Contact lens case maintenance is very important to prevent eye infections.

For those irresponsible contact lens wearer to comply with the hygiene care in handling contact lens case will cause microbial biofilms to build-up in the contact lens case. Thus, causing contamination of Acanthamoeba, bacterial and fungal. Without proper contact lens case maintenance, contact lens wearer is easily exposed to eye infections.

Diagram below show the process of microbial biofilms build-up formation in the contact lens case;

Corneal infection is the most common vision threatening complication of contact lens wear. Organisms isolated from contact lens associated corneal ulcers have often been shown to be identical to those isolated from the contact lens case, making the contaminated contact lens case a possible replenishable source of pathogenic microbes.

Diagrams below shows the close-up, magnified of obvious microbial biofilms build-up on the contact lens case;


Thus, contact lens wearers are recommended to follow the proper cleaning and disinfecting regime. Many of the contaminants identified were potential pathogens and should have been prevented by the disinfectant regimen used. However, at certain level adherence of microbial biofilms onto plastic surfaces, will enable them resistance to antibiotics and antiseptics.

Following methods in contact lens case maintenance, should result less contact lens case and contact lens contamination, are:

  • Ensure hands are wash thoroughly before handling contact lens case
  • Scrub regularly all internal surfaces with a clean cotton bud moistened with contact lens cleaner – to prevent accumulation of microbial biofilms.
  • Always leave the contact lens case open to air dry when not in-used.
  • Replace the contact lens case regularly, at least 3 months once.
