When it comes to eye care, what’s your vision IQ?

By KTVA CBS 11 News 3:28 PM December 6, 2013

Test your knowledge

ANCHORAGE- Glasses, contacts, even surgery — we’ll try anything to improve vision, but what’s your vision IQ?

True or false…

1) Lasik is a one-time procedure. FALSE.  About 10.5 percent of lasik patients in the U.S. require a retreatment or enhancement. This applies to patients who have severe cases of eye conditions.

2) As long as your eye prescription is stable, you’re a good candidate for lasik. FALSE. Those with thin corneas and diabetics with reduced corneal sensation should avoid lasik.

3) What about contacts? If your contact is dried out, you can use saliva in a pinch. FALSE. Doctors say with all the bacteria in your mouth, you’re just asking for an infection.

4) Sleeping in your lenses is okay as long as they’re approved for that purpose. FALSE. “No patient should ever sleep in their contact lenses,” said Dr. Ernest Kornmehl, medical director at Kornmehl Eye Associates.  “It’s well documented there’s a seven times higher risk of corneal ulceration.”

5) There are other options to correct your vision aside from contacts and laser surgery.  TRUE. Consumer reports found implantable lenses had similar benefits to laser surgery. However, implants are reversible and there’s no risk of damaging your night vision. No procedure is risk free. Implantable lenses may increase your risk of cataracts.

According to Dr. Kornmehl, always do your homework before you see a doctor.
