This is dependent on how the surgery is done and the technique used. In general I tell my patients that they may have significant foreign body sensation and sensitivity to light and some pain for 2 to 4 days and that would be the minimum time off. Some can be uncomfortable for a week but that is unusual. One important thing to note is that you must comply with your post-op drop regimen and that even though you can work, the eye will be red for several weeks at least and perhaps up to 3 months or so. This redness will not prevent you from working.
