Frequently Asked Questions
 Q: Are both eyes treated at the same time?
Yes. Large scale studies conducted over a decade ago demonstrated that there was no difference in safety between single- eye surgery and bilateral surgery. In fact, some evidence suggests that it is actually safer to treat the second eye immediately following the first eye. There are, of course, certain situations where your surgeon may suggest doing one eye at a time, but this would generally be due to specific
medical issues.
Q: What will I feel during and after the laser eye surgery procedure?
There is no pain involved during laser
eye surgery. You will be given a topical anaesthetic to numb your eyes - most patients report feeling some pressure on the eye (which can be a strange sensation) but not pain. Many LASIK and SMILE patients do not experience any discomfort after surgery - although it is normal to experience some grittiness, light sensitivity and eye watering for the first 24 hours. After surface procedures (PRK, LASEK and Epi-LASIK), the eyes take a few days to heal. However, patients should not find the healing process painful, as they are given pain-relief medication and fitted with bandage contact lenses.
Q: How long does laser eye surgery take?
The treatment takes only minutes and the laser itself is only active for seconds.
Q: What happens if I look away, blink, cough or sneeze during the procedure?
Nothing. Although your eye will move during surgery, eye tracking technology ensures your safety when this happens - the laser tracks your eye hundreds of times every second, and compensates for any movements.
Q: What is the risk of a complication during laser eye surgery?
Laser eye surgery is safe, but no surgery
is entirely without some level of risk. Thankfully, an expert surgeon will have
the knowledge to manage complications properly, and will usually be able to correct any complications that do occur. In the hands of an expert surgeon, the chance
of something going noticeably wrong
is around one in 1,000 procedures. The chance that such a surgeon would be faced with a situation he or she would not be able to correct satisfactorily is about one in 30,000.
