Can both eyes be treated simultaneously, or is it better to operate on each eye individually?
Both eyes can be treated at the same time. In as much as the procedures are generally safe, effective, and predictable a number of patients and surgeons will have both eyes done at one sitting. That being said, some surgeons/patients prefer to do only one eye at a time. This is safer as should their be some problem (which occasionally happens), with over or under correction, infection, epithelial ingrowth or many other rare but, possible complications then presumably only one eye would be damaged or lose best corrected visual acuity. However, if each eye is done separately then there are two appointments for treatment and two healing periods etc.
