For this week’s post, we have Dr. Jenifer Bossert, Optometrist and Director of Contact Lens Services at Honolulu Eye Clinic.  She recently appeared on KITV news to discuss serious dangers of improper contact lens storage which could be putting your eyes at risk.

 

In addition to disposing of your contact lenses in a  timely manner, here are a few other things you could consider:

When was the last time you really looked at your contact lens case?

When was the last time you actually replaced your contact lens case?

Did you even know you were supposed to replace it?

Several studies have confirmed that 70% to 82% of cases show contamination from overuse.  And only 26% of patients replace their cases periodically, 48% once per year, and the remainder, never!  Median frequency for cleaning cases was 2-3 times per week and one third cleaned only once per month!

Lens cases are hotbeds for bacteria and fungal colony growth…despite the addition of the Multi-Purpose Solution (MPS) contact lens solutions.  Cases are made from porous plastics.  Over time a “biofilm” coats the inner surface of the case.   This serves as a breeding ground for bacteria.  These bacteria become embedded in the pores of the case itself.  Even IF you properly follow contact lens cleaning and rinsing instructions, these nasty bacteria still find a way to grow.

When present, they can attach themselves to the micropores in the contact lens, multiply, and form this undetectable film on the contact lens, which is then transferred to the eye upon insertion.  These deposits irritate the cornea–the soft clear tissue on the front of the eye—causing the wearer to rub the eye and the eye to appear red.  The back and forth pressure from rubbing makes microscopic scratches on the surface of the eye. These small breaks in the tissue act as open pathways for the bacteria to invade the eye, thereby, increasing your risk for a bacterial infection and/or corneal ulcer.

Your best line of defense is following these instructions EVERY day:

  •  NEVER “top off” and reuse the solution in your case for a second day.
  •  After removing contact lenses, empty the case,  and rinse it with fresh MPS (not water).
  •  Turn it over (to keep the dust out) and let it air dry.
  •  REPLACE the case every 3 months.

Following these simple rules will reduce your risk of case and contact lens contamination.  Please remember that not all contact lens solutions are MPS (i.e. disinfecting) solutions so it is important to read the labels.  Saline is NOT a disinfecting solution.  If you have any questions regarding the proper solutions to use with your particular contact lenses, don’t hesitate to call and ask your doctor or the staff here at the Honolulu Eye Clinic!  We would love to hear from you!

 

I was trying to think of a good title for this blog post and I was reminded of FB posts I see and thought of : “This boy bought his Halloween contact lenses online and you wouldn’t believe what it did to his eyes!”  (He didn’t really, this is our Optician who purchased the lenses through our clinic).  But, that title was a bit too sensational for me, so I just thought a nice, simple title would suffice, though the dangers are very real.  I lived in Manhattan for 8 years and the Halloween parade down in the Village is legendary.  You see the best costumes and everyone gets dressed up.  That was the first time I saw someone in a costume contact lens – it was a cat eye and I thought it was cool.  I was an ophthalmology resident at the time, and I asked the girl where she got them “Oh, from the costume shop down on 14th Street”, she answered.  Yowser!  I couldn’t believe someone would put something in their eye that they bought at a pop up Halloween store!  That was about 8 years ago and now people can buy contact lenses online, which makes the dangers even more widespread.

Of course, we all want to have the best costumes for Halloween.  And, the cosmetic contacts add a little something extra – Walking Dead zombie with the crazy eyes; vampire with red rimmed iris, or cat eyes – all make for an exceptional outfit.

 The problem is that people do not realize that these kind of lenses require the same fitting and care as a regular contact lens.  People mistakenly believe that because it’s just for one night, that somehow these contacts do not need to be as safe, or fit as well, which is far from the truth.  Ten hours is more than enough time for bacteria to grow and for a serious, vision threatening infection to occur.  And, just because you can buy them online or in a novelty shop does not mean that they are.  Remember, all contact lenses are medical devices and should be approved by the FDA.  In fact, shops which sell non-FDA approved lenses or do so without requiring a prescription from your eye doctor are conducting business illegally can receive stiff fines, of up to $11,000.  Any place that sells contact lenses should ask you for a prescription.   The lenses pictured above are sold in our clinic and are FDA approved material.    The FDA has issued warnings in the past about the dangers of wearing Halloween contacts.

Dr. Jenifer Bossert, Director of Contact Lens Services at Honolulu Eye Clinic, offers this advice: “In our practice, I tell patients daily that contact lenses aren’t a “one size fits all”.  Just like everyone has a different size foot, everyone has a different size eye…and if your contact lenses aren’t fit to your eye, you run the risk of corneal ulcers, distortions, discomfort, and yes, even the potential for blindness as a result from a significant bacterial infection.  Halloween is such a fun time…and we want our costumes to be awesome…so think ahead, call your eye doctor early, and “treat” your eyes well!

 

Tips for a Safe Halloween with your costume lenses:

1.  Have your eyes examined by  a licensed eye care professional.  They can measure your eyes appropriately and discuss proper care of contacts.  This is especially important  for those of us (like me) who don’t wear glasses or contacts regularly.  We are just not as skilled at inserting or removing contact lenses and that is important at preventing scratches on the cornea.

2. Get a valid contact lens prescription which includes power, brand type, base curve measurements and expiration date

3.  Buy lenses from an eye care professional or vendor who requires a prescription.  We do offer the following contact lenses for sale.  The bottom ones are also available with prescription.  Today is the last day to order in time for Halloween.  Though, based upon their availability, there is a small chance that the lenses might not arrive in time since we live out in the middle of the ocean.  However, these lenses are available year round if you want to buy them early for next year for any upcoming  costume parties!

4.  Follow directions for proper cleaning and care of contact lenses.

5.  Never share your contact lenses.  This was the worst case I saw in NYC.  A 14 year old girl shared contacts with her friend and developed a terrible corneal ulcer and became blind in one eye from it.  It seems innocouus, but it is not just another part of your costume!

6.  Maintain proper follow-up appointments with your eye doctor.

Following these simple guidelines, should allow you to have a safe and fun Halloween!
