Laser Eye Treatment - What Are The Risks Of LASIK?

But like any type of surgery, laser eye treatment does involve a risk. It may be small, at only 5 percent of cases, but it's still there, and you need to be aware of the potential side effects or risks of undergoing laser eye treatment before deciding to go ahead. Here are the main possible side effects:

Under correction or Over correction

Although technology has improved the accuracy of the laser equipment, there's still a chance that the eye will not respond well to the laser eye treatment. It's possible that you may still need corrective lenses to achieve clear vision. It may also be necessary for you to undergo further surgery in order to improve an under correction or over correction issue.

Eye Infections

In a few cases, the eye can become infected after surgery. Although this usually clears up with appropriate treatment, it can delay the healing process in the eye.

Detachment of Flap

The first 24 hours after the operation are crucial, because during that time it's possible for the flap of tissue created during surgery to become detached. This is only likely to happen if you injure or directly touch your eye, but it's still a risk. It's important to be very careful if you need to handle your eye in any way during the first 24 hours. After this the flap remains attached and is much harder to dislodge.

Presence Of A Halo

Some people experience this side effect in dim light. It's an optical affect, and is more commonly seen at night, but generally the halo effect disappears after a week or two. The untreated peripheral cornea triggers this faded second image. You should consult your eye surgeon if you find the problem persists past two weeks. It's also a good idea to avoid driving if you're experience a halo effect.

Dry Eyes

After laser eye surgery, you may find your eye doesn't produce enough tears to keep your eye moist and clean. As a result, you may feel a burning sensation in the eye, or sometimes your vision will blur slightly. If you find this is really concerning you, see your doctor for information about intensive drop therapy.

Even though the risks I've outlined above are very real risks, the reality is that they are also very minor. Thousands of laser eye procedures are carried out successfully every day, and most patients find their vision is clear and healthy thanks to laser eye treatment.
