Contact Lens Solution & Lens Use

Corneal Transplants Have Resulted from Faulty Eye Solutions

Recent problems with Bausch & Lomb MoistureLoc and AMO (Advanced Medical Optics) Compelte MoisturePLUS solution have resulted in dangerous eye infections and vision loss.

This is information you should know about contact lens use and the dangers of certain solutions that are on the market. Most of the problems have occurred in one-step, multi-purpose solutions. These no-rub solutions have been at the heart of CDC and FDA investigations over blindness and severe eye infections.

Guidelines for soft contact lens use
All contact lens users should follow established guidelines to help reduce the risk for serious eye infections, including Acanthamoeba keratitis. Here are some additional contact lens wearing recommendations:

  • Visit your eye care provider for regular eye examinations.
  • Wear and replace contact lenses according to the schedule prescribed by your eye care provider.
  • Remove contact lenses before any activity involving contact with water, including showering, using a hot tub, or swimming. Extended-wear contact lens users should discuss their concerns with their eye care provider.
  • Wash hands with soap and water and dry before handling contact lenses.
  • Clean contact lenses according to the manufacturer's guidelines and instructions from your eye care provider.
  • Use fresh cleaning or disinfecting solution each time lenses are cleaned and stored. Never reuse or top off old solution.
  • Never use saline solution and rewetting drops to disinfect lenses. Neither solution is an effective or approved disinfectant.
  • Store reusable lenses in the proper storage case.
  • Storage cases should be rinsed with sterile contact lens solution (never use tap water) and left open to dry after each use.
  • Replace storage cases at least once every three months.

About Corneal Transplants
The cornea is the front window to the eye. The cornea allows light into the eye and refracts the light rays to help the lens focus on the retina. Corneas must be crystal clear and of the proper curvature.

A cornea may be cloudy because of eye injuries from wounds, sharp objects, burns or chemicals. Corneal infections may be caused by bacteria, viral, or fungal in nature. Severe infection will lead to scarring. Fungal keratitis (also known as fulsarium keratitis) and Acanthamoeba keratitis (AK) may lead to corneal scarring.

As with any operation, a corneal transplant has some degree of risk. The success rate is often relative to the cause. Transplants due to scarring of the cornea from infections typically have a lower success rate.

How to contact the FDA if you have an infection from Len Solution: The FDA can be contacted at 800-FDA-0178. MedWatch is on the lookout for these problems and is eager to learn of individuals having eye infection problems from AMO. AK - Acanthamoeba Keratitis is a rare and very dangerours eye infection and needs immediate medical attention. With so many AMO patients suffering this problem, the product has been linked to causing the infections in many users.
