This is probably the most common question we get from people considering LASIK. I tell everybody that anything could happen including having a heart attack and dying! We know this sounds drastic but in reality, death and blindness are probably as likely as being hit by a truck crossing the street.
We would not refrain from considering the procedure because am concerned about blindness. LASIK is not without risks but we take risks on a daily basis. Consider contact lenses.They also have a significant risk of infection, damage to the eye, etc. Yet, many of us will take the risk of contact lenses for the convenience they provide.
In general, LASIK is a very safe FDA-approved procedure for a good candidate. It is not for everybody.
The key is to ensure that you are a good candidate.
