Excellent OrthoKeratology Video

With the increased rate of myopia in the US population, orthokeratology is becoming an increasingly important treatment option for our patients.  Dr. Driscoll is a member of the Orthokeratology Academy of America that produced the excellent video shown below.  The video gives a comprehensive overview of orthokeratology, including its pros, cons, and how it works. We highly recommend that any patients considering refractive surgery, such as LASIK and PRK, or orthokeratology view this video. By the way, comments are much appreciated so don’t be shy.

CooperVision Avaira Contact Lens Recall

It seems that no contact lens manufacturer has been immune to a recall of their contact lenses. CooperVision announced a global recall of selected lots of their Avaira® Sphere and Avaira® Toric contact lenses.

The recall is due to the amount of residual silicone oil left over from the manufacturing process. The symptoms reported range from blurry vision to pain and irritation.   Only a small number of Avaira contact lenses are affected. To see if your lenses are affected enter your lot number on the CooperVision Contact Lens Recall Website. If your contact lenses are on the recall list CooperVision recommends returning them to the point of purchase for replacement.

Rub and Rinse Contact Lens Cleaning Method Shown to be More Effective Than No Rub Technique

A study out of Australia has confirmed what eye doctors have long suspected. Rubbing your contact lenses and briefly rinsing them prior to overnight storage and disinfection is more effective at removing bacteria from the lens surface than merely placing the contacts in the case (no rub technique). Numerous multipurpose no rub contact lens solutions have been approved by the FDA  and shown to be an effective method of disinfecting contact lenses however this study shows that applying a few drops of the multipurpose solution, rubbing and then rinsing the lenses is much more effect at removing bacteria from the lens surface.

This study was done “in-vitro” meaning that it was a lab study where patients did not actually wear these lenses but the lenses were seeded with bacteria and then after the lenses were cleaned and disinfected the lenses were then testing to see how much bacteria was removed.

So the moral of the story is after removing your soft contact lenses add a few drops of the multipurpose contact lens solution, rub both sides of the lens then rinse the lens and place it in the case to disinfect overnight.

Contact Lens Cases – An Often Overlooked Source of Eye Infections

When was the last time you replaced your contact lens case? Next to dirty hands contact lens cases are probably the most common source of bacteria that will contaminate your contact lenses.  The best time to replace your contact lens case is when you get a new bottle of contact lens solution, or better yet make the move to daily disposable contact lenses and skip the contact lens case and solutions altogether.

Contact lens casesTo prevent the contamination of your contact lens case the eye doctors at Total Eye Care recommend that you thoroughly rinse the entire empty contact lens case, including the lid or caps with tap water. Next air dry your case by placing it upside down on the counter.

New Keratoconus Treatment Options for Patients

Due to the fact that one of the specialties at Total Eye Care is keratoconus we see many patients with this condition.  We recently updated our patient information on keratoconus page to reflect some of the new technologies available to our patients such as;

  • Mini scleral lenses, which provide excellent vision like that of traditionally fit gas permeable lenses, however with markedly improved comfort.
  • Corneal collagen cross linking, though not yet FDA approved, is a new technology that I expect will be of a tremendous benefit to our patients.

FDA Study Cites Contact Lenses as Leading Cause of Medical Device Related Emergency Room Visits

During a 24 month study of 100 hospitals contact lenses accounted for 23% of
medical device related emergency room visits involving children.

In a study published online this week in the journal Pediatrics entitled “Emergency Department Visits for Medical Device-Associated Adverse Events Among Children” it was found that 23% of the medical device related emergency room visits involving  children from birth to 21 years of age were contact lens related, this is in contrast to the next closest category,  injuries due to a puncture by a hypodermic needle, which placed a distant second at 8%.   An additional noteworthy finding was that an another 6% of the ER visits  involved lacerations caused by eyeglasses.

The study did not outline how the children were using their contact lenses.  Were they caring for and cleaning them properly?  Did they discard the lenses according to the replacement interval prescribed by their doctor and what type of contact lenses were involved in the study?  The injuries incurred while wearing eyeglasses did not specify the type of activity the child was participating in when the incident occurred.

Contact lenses are medical devices and as such require a prescription from an eye doctor with professional fitting and followup. In clinical practice we have found that patients that follow the guidelines below rarely experience contact lens related complications.

Injuries due to eyeglass lenses and frames was also a significant source of injuries in the study. We must therefore, not forget to provide our children with protective eyewear when they participate in sports.  Sports eyewear has come a long way since the days when Kareem Abdul-Jabbar captured his trademark look.  Sports eyewear has now become fashionable and safe.

How are Soft Contact Lenses Made?

Have you ever wondered how soft contact lenses are made?  We found this Discovery Channel video from the show How Do they do it? showing how custom soft contact lenses are made.  

National Public Radio’s Medical Detectives Explore Increased Nearsightedness in the US

Photo of Child gazing out windowIn December 2009 we covered the results of a recent study Myopia Increasing Rapidly in The US Population. Recently National Public Radio’s Medical Detectives interviewed, Dr Susan Vitale, principle author of the study “1994-2004 National Health and Nutrition Examination Survey” and Dr. Don Mutti, an expert in myopia.  It’s a good listen and only a little over 3 minutes.

With myopia increasing at such a rapid rate in our population will it be long before the use of orthokeratology to slow the progression of myopia in our children becomes the standard of care?
