Laser eye surgery is about reshaping your cornea to correct the problem of short sightedness, long sightedness and astigmatism.
Different kinds of laser eye surgery
All laser eye surgeries will deliver similar results to improve your vision. The difference that lies between them is the recovery period and time off work.
Your eye surgeon will discuss about each procedure in more details at the initial consultation. Then he will give advice on the right procedure that has been suited to fulfill your requirements.
This is the commonly performed laser eye treatment. In case of LASIK procedure, there were two different kinds of laser being used. Firstly, there is a femtosecond laser that forms a thin and protective layer with a 3D pattern of small gas bubbles through your corneal tissue. This layer will then be lifted back by your eye surgeon before an excimer laser tries to reshape cornea for improving your eyesight. After this, the protective flap gets replaced for completing the procedure.
The cell layer of the surface begins to heal around the flap’s edge and the vision starts improving by the next 3 to 6 hours. Once the surgery is done, most people will be able to see clearly while working and driving.
LASEK and TransPRK surface laser treatment
Surface laser treatments can be done directly beneath the skin layer of your cornea. This can be removed by the surgeon (LASEK) or the laser (TransPRK) before correcting your eyesight. The visual recovery is slower when compared to LASIK eye surgery as it requires skin layer to grow back within a few days and smooth off by few weeks. Surface laser treatments are usually considered to be best possible option for patients who have thin corneas.
After the surface cell layer gets healed, your eyesight begins to improve and reaches the driving standard within 1 to 4 weeks after LASEK or TransPRK eye surgery, based on your case. Most patients will have to take at least one week off from their work after the surgery.

How safe is laser eye surgery?
There might be serious complications following laser eye surgery though it seems to be rare. Few patients may need to undergo further surgery for replacing damaged tissue into the cornea.
Despite the latest advancements, all eye surgery has some risks of complications. But most of these problems can be fixed and so, putting your contact lenses seems to be a great alternative to laser vision correction for patients. But it is not completely risk free and 1 in 1000 people who wear the lenses may develop serious corneal infection.
Your eye surgeon will be discussing about any possible risks with you before you decide to proceed ahead with the surgery.

This usually takes place when the SMILE lenticule or LASIK flap has been formed. They may even suffer from mild discomfort for almost 4 to 6 hours post the surgery.
If you are extremely worried about the surgery, then you may take a sedative tablet to ease the discomfort.
