We do recommend that you wear a pair good quality UV protection sun glasses after laser eye surgery.
Your eyes will certainly feel very sensitive to the light in the hours immediately after your treatment, though a lot of patients say they feel better for wearing sunglasses for the first few days.
Not only do sunglasses obviously provide protection from harmful UV rays, but they also acts as a barrier against wind and dust particles and also stop the wearer inadvertently touching their eyes.
The need to wear sunglasses is usually only necessary for the first few days, however, if you are going on holiday or somewhere where it is particularly bright it is advisable for you to wear them for longer.
It is in fact good for your eyes in general, regardless as to whether you have recently undergone laser treatment or not, that UV sunglasses are worn on bright sunny days. Please discuss this with your doctor at your consultation as some patients (especially those having LASEK may be required to wear sunglasses for longer).
All eye surgical procedures carry a level of risk including not obtaining the desired outcome, through to varying levels of visual loss. Your eye surgeon will discuss the risks and benefits, including ones specific to your circumstances, at the time of your pre-operative consultation.
