With its popularity increasing, LASIK (Laser-Assisted In-Situ Keratomileusis) surgery has aided millions around the world with their eyesight and saying goodbye to contact lenses and glasses. People with eye problems favor this surgery for its minimal pain and ability to restore vision the following day.

However, before you entrust your eyes to LASIK surgery, here are five things that you should be aware of.

1. How does LASIK work?

This surgical operation helps improve people suffering either from near or farsightedness. During operation, the eye surgeon will use a surgical instrument called microkeratome to peel off a circular “flap” in the cornea. With access to the cornea, the surgeon will then remove the necessary corneal tissue using a specialized excimer laser and adjust the cornea.

Once this is done, the flap will be substituted over the section where the tissue was removed and is used as a bandage over it. For accuracy, the performing surgeon uses a computer to calculate data and fine tune the laser for each individual’s eye needs.

2. What to do before undergoing LASIK?

Before going through such a major surgery, it is very crucial to find a well known and respectable eye doctor. By doing so, you can create a bond with your doctor and he or she can give you a complete assessment and lessen the chances of any complications.

In the off chance that you have dry eye disease, it would be necessary to treat it before LASIK procedure. As mentioned, your doctor will check your overall health and determine whether you meet the criteria to go through an eye surgery.

Moreover, it’s important to have a thorough talk with your doctor and be aware of the risks and expectations before going under the surgeon’s table.

3. What happens during treatment?

LASIK surgery is brief and you will be conscious throughout the procedure. The surgeon will recommend a moderate sedative before the treatment. Additionally, anesthetic drops will be put on your eyes, and while on the table, the surgeon will position the laser in line with your eye. Your eye will be held open by a retainer with a suction ring and the surgeon will then proceed with the surgery.

After the surgery, while you may be able to walk out of the hospital on your own, it is advisable to bring a friend along to ensure you reach home safely.

4. Are there any complications?

After LASIK surgery, one of the most common complaints are of dry eyes. These can be remedied using eye drops or artificial tears. Within six months, these symptoms will dissipate and will entirely disappear. Should you contract an eye infection, it is recommended to see a doctor as soon as possible.

5. What to expect?

During the doctor’s assessment, you should be aware what the end result after surgery. While a 20/20 vision is the preferred outcome, a 20/40 would be sufficient to drive or walk around with the need for glasses or contact lenses. However, if the estimated result does not fulfill your expectations, then you will have to pool all your research together and decide according to projected outcome, risks, and expense.
