No. Singapore lasik procedure is carried out as an outpatient procedure (Surgeries that allow the patient to return home on the same day after a surgical procedure is performed) and you can go home after the procedure on the same day.
The surgery itself only takes about 10 minutes or less per eye, however, you should expect to spend at least a couple of hours for the pre-operative preparation, post-operative recovery and evaluation.
The Pre- Operative evaluation is a comprehensive eye examination with over 15 tests to give the doctor a clear picture of the overall health and focusing abilities of your eyes.

Although no hospital stay is required, you should avoid driving for a day or two after the Singapore lasik surgery, this means that you should arrange someone to pick you up after the surgery. Some patients experience a few symptoms after the surgery, but these symptoms should be gone within a few days. The symptoms include extra sensitivity to light, watery eyes, runny nose, sensation similar to having dust or eyelash in the eye, hazy vision; such as glare or halo effects around the lights in the evening1. These symptoms are considered common and you shouldn’t be alarmed, but if any of those goes on for more than a few days, you should consult with your doctor at the earliest convenience.
