B. The Misconceptions About Vision Correction

Narrator: This is Science Today. People considering new vision correction treatments should be very clear about the outcome of such procedures. Ophthalmologist Doug Holsclaw of the University of California, San Francisco says there's too much misinformation about the new laser treatments.

Holsclaw: Part of the hype is everyone envisions this as something almost Star Wars-like. Like, you lay down underneath the laser and you sit up two minutes later and your vision is perfect, but you can't promise any individual person that their vision will be perfect after having this done.

Narrator: While the procedure has had phenomenal results with distance vision, Holsclaw says people should hang on to their glasses.

Holsclaw: Some of the real fine visually demanding things like maybe driving long distances at night, you may need to still wear a little, tiny bit of correction and if that sounds like a good thing to people than I think it's a reasonable thing to go forward, but if someone's saying that the only way that they're going to be happy after having this done is if you can guarantee that they won't have to wear glasses afterwards - no one can do that.
