Replacement Schedule

Replacing your lenses more often is healthier and more comfortable for your eyes. Organic (i.e. protein and lipids) and inorganic materials (i.e. calcium) found naturally in your tears can collect on your lenses. The collection of material on your lenses causes irritation, redness, shortened wearing times and makes your eyes more susceptible to infection. Cleaning and disinfecting your contact lenses extends their life and wearability, but is still no substitute for regular replacement. Some material is unable to be removed and the contact lenses just wear out over time. Each brand of contact lenses comes with an FDA recommended replacement schedule, which includes one day, two weeks, one month, three months and yearly.

Contact Lens Solutions

The ideal contact lens solution would disinfect and clean a contact lens without causing irritation or allergic reactions. A peroxide based solution like Clear Care or Oxysept come closest to this. With peroxide solutions, hydrogen peroxide is used to clean and disinfect the lenses, but it requires a neutralizing agent and six hours to neutralize. After six hours the lens has been disinfected, cleaned and the solution is preservative-free. If any type of irritation exists with contact lenses, a peroxide solution is the way to go. It can be a problem-solver. However, waiting six hours can be very inconvenient and not very practical. For example, if a contact lens is dropped and needs to be cleaned, waiting six hours until you can wear it is not very useful. Because of this there are multi-purpose solutions that clean, disinfect and rehydrate contact lenses. However, they contain preservatives and anti-microbial chemicals that can cause irritation and discomfort in some patients. This is especially true of some of the generic brands. Some of the better name brands include Biotrue, Complete and Optifree.

Insertion
  1. Wash hands with soap free of lotions and perfumes, dry hands with a lint-free towel
  2. Open contact lens foil or remove contact lens from case
  3. Rinse contact lens prior to insertion; make sure it is clean and slightly wet.
  4. Place contact lens on the index finger of your dominant hand, the lens should have a slight curl to it
  5. Put your other hand over your head and with your middle finger pull your upper eyelid up.
  6. With your dominant hand’s middle finger pull the lower eyelid down and then with the contact lens on your index finger place it on the colored portion of the eye.
  7. Next slowly blink to smooth out the contact lens on the eye, some patients will move their eye around prior to blinking to help it center.

Removal 

  1. Look up with your eye
  2. Pull your lower lid down with your non-dominant hand
  3. With your dominant hand’s index finger pull the contact lens onto the white portion of the eye
  4. Then with the tips of your thumb and index finger of your dominant hand gently pinch the lens and pull it off
  5. Place the lens in the palm of your hand, apply a little contact lens solution and gently rub it to help remove any protein build up
  6. Place the contact lens in its case with fresh contact lens solution and let the lens soak
Contact Lens Wearing Tips & Recommendations
  1. Having long fingernails can make inserting and especially removing contact lenses more difficult. You are more likely to scratch your eye or tear the lens.
  2.     Contact lenses should be applied to the eye prior to any application of make-up, lotion or perfume to avoid contamination of the lens.
  3.     Rubbing your contact lens after removal is important to do even if your contact lens solution states “no rub.” The mild abrasion that occurs when rubbing your lens gently removes deposits that solutions don’t remove.
  4.     If your eyes dry out during the day when wearing your contacts, remove them for about one half hour and let them soak in a saline solution. This will “re-hydrate” the contact lens and allow for a more comfortable and longer wearing-time.
  5.     Using a contact lens longer than the recommended replacement time increases your risk of eye infections and irritation. Wearing your contact lenses too long causes the contact lens material to breakdown, material and organisms accumulate, which may lead to a breakdown of the corneal epithelium barrier and create a vector for infection.
  6.     Never use tap water or saliva as a solution for contact lenses. It increases your risk of infection also.
  7.     Contact lens cases should be replaced every two months or when visibly contaminated.
  8.     After removing your contacts from their case for insertion, dispose of the old solution and let the case air dry during the day.
  9.     It is not recommended that you swim with your contact lenses on. If you do they need to be cleaned very well with a peroxide solution or even better, disposed of.
