Many people are often afraid of eye surgery risks, but the advantages of laser eye surgery far outweigh any potential risks. If LASIK goes wrong, however, the complications can almost always easily be fixed by further surgery.
Laser eye surgery is used to correct myopia (farsightedness) and hyperopic (myopia or nearsightedness). It does this by reshaping the cornea. The cornea itself is made up of three lenses – a front, a middle and back part. When you squint, one of these lenses may be obstructed, causing a blur. The other two lenses, the middle and back part, are responsible for correcting the blur by providing clear vision.
There are two main types of LASIK: open and closed. Open LASIK involves the surgeon cutting the eye. Then, they reshape the cornea in such a way that it can hold the laser beam. This is known as the ‘open procedure’. Then, after the reshaping, they put the LASIK surgery mask over the eyes are stitched back into place.
Laser LASIK surgery risks involve two main types. One type of risk is known as the ‘perioperative complications’. In these cases, the surgery may not be successful and so the patient must undergo another surgical procedure. In some of these complications, there are infections that can spread and cause permanent damage.
Infections are also a risk. These infections can occur in the eye, in the surgery, or both. For instance, bacteremia can occur when bacteria get into the surgery itself, and they can spread and cause infection. Other complications include conjunctival bleeding, tears, and even loss of sight.
In order to avoid some of the more serious complications, you have to find out what the risks of LASIK are first. There are a few things that you can do to reduce the risk, though. Some of these are:
If your surgeon does not tell you about these risks, ask him or her. If you know a person who has undergone LASIK, ask them if they have had any complications and what they did to reduce them. Some surgeons will also mention these risks on their websites, but these are often only in medical terms. They may refer you to an eye surgeon with more experience. Also, if you think you might be at risk for complications, talk to your surgeon right away so you can speak to a specialist who can give you advice about your health.
You should be aware that even if the risks were reduced, they are still there. You must also know your eyes are important enough to take the necessary precautions to prevent the risk from occurring, and you should never accept that the risk is unavoidable.
For minor complications that are caused by an infection, antibiotics are available. These are commonly used after the surgery has been performed, and they are also effective against infection and also reduce the risk of vision loss. In the rarest cases, surgery cannot be done to reduce the risks because the bacteria or virus causing the infection has been removed.
Once the surgeon removes the eye, he or she will usually remove the flap, as well. When the flap is removed, the corneal flap will heal with healing fluid.
You should also consider the following LASIK risks if you have a history of eye problems, such as cataracts, astigmatism, or macular degeneration. If you have experienced problems with your vision before, your surgeon may tell you to avoid LASIK surgery because of these risks.
It’s important to understand what LASIK risks are and how to reduce them. The LASIK surgery risks and benefits should all be discussed with your doctor before you have this procedure done. Make sure you have discussed these with your surgeon and that he or she has your medical history. This way you are sure you have the facts about your options and you can make an informed decision.
