This is a recommendation that you have your LASIK records available, for your own good, later in life.

There are 2 million cataract surgeries done yearly in the U.S. and the odds are, if you live long enough, you will eventually need cataract surgery, too.

What does this have to do with LASIK surgery? 

When doctors perform cataract surgery they remove the cataract, which is the lens of your eye that has become cloudy.  And they replace that lens with an artificial lens called an Intraocular Lens implant (IOL).

The IOL needs to have a strength to it to match your eye so that things are in focus without the need for strong prescription eyeglasses.

The Background

Over the last several years, research has indicated a strong correlation between the presence of Obstructive Sleep Apnea (OSA) and glaucoma. Information from some of these pivotal studies is presented below.

Did you know

  • Glaucoma affects over 60 million people worldwide and almost 3 million people in the U.S.
  • There are many people who have glaucoma but have not yet had it diagnosed.
  • Glaucoma is a leading cause of blindness in the United States. 
  • If glaucoma is not detected and goes untreated, it can result in peripheral vision loss and irreversible blindness.

  • Sleep apnea is a condition that obstructs breathing during sleep.
  • It affects 100 million people around the globe and around 25 million people in the U.S.

  • Poor sleep due to sleep apnea results in morning headaches and chronic daytime sleepiness.

The Studies

In January 2016, a meta-analysis by Liu et. al., reviewed...

This is especially true for children who were born prematurely and have a very low birth weight and may need to be given oxygen.
