Re: [IP] Lasik
The margin of error is kind of a bad phrase. With high prescriptions and
thinner corneas there is a greater chance that the eye will not hold the
correction quite as well as someone with a small prescription and thick corneas.
In the high prescriptions we like to have thicker corneas so once the eye
stabilizes we can go back in and fine tune the correction. The complications
such as decreased night vision and glare are problems more related to older
technologies of laser correction. They still have to get mentioned because they
occurred in the initial clinical trials 20 years ago.
