Laser and Refractive Eye Surgery


Ophthalmological technology is evolving at a rapid pace. This has resulted in hope and potential for many cases that were previously thought of as untreatable. People are now choosing laser and refractive eye surgery to enhance vision and benefit from its proven track record.

Laser surgery can help patients overcome a wide array of conditions. But it is most typically used to rectify refractive issues in the patient’s eyes.

Patients are afflicted with issues of refractive errors due to malformed eye structure. As a result, the cornea wrongly bends the light instead of doing it the expected way. With laser surgery, the surgeon rectifies the eye’s shape. They try to correct the issue with the help of a cutting laser.


The Importance of Laser and Refractive Eye Surgery:

Are you looking to undergo laser eye surgery? You would need to exercise due diligence by being contact lens free for a few weeks before assessment and consult with an experienced ophthalmologist. The expert will examine your specific eye condition. This will help him determine the risk level associated with laser surgery.

Surgeons may recommend laser surgery for one of the below issues with the eye –

  • Myopia: Nearsightedness, or myopia, causes the eyeball to be a bit longer than normal, which results in light rays focusing in front of the eye, causing the person to have blurred vision when trying to focus on objects that are at a longer distance.
  • Hyperopia: When the eyeball is shorter than average, light entering our eyes focuses behind the retina. This can result in blurred vision when trying to focus on objects that are closer to the eyes.
  • Astigmatism: This condition happens when the cornea is flattened or curves unevenly. This can result in the disruption of both close and distant vision.

Eye Surgery

Though laser eye surgery offers great results for majority of the patients who opt for it, it is important to note that complications can also occur after the procedure. Before undergoing the surgery, your doctor will also ask for your detailed medical history since certain health conditions such as autoimmune diseases and inflamed cornea may increase the risk factors.

Some of the side effects of laser eye surgery can include:

  • Dry eyes
  • Double vision
  • Undercorrections
  • Astigmatism
  • Flap problems
  • Overcorrections
  • Regression
  • Vision impairment

How Laser and Refractive Eye Surgery Works:

Before undergoing laser and refractive eye surgery, you will have to prepare yourself beforehand. If you happen to wear contact lenses, your ophthalmologist will advise you to only wear glasses a few weeks before the surgery. It is important to know that laser surgery works best for patients who are carefully evaluated by their doctors in order to determine what kind of laser surgery is best suited for them and will give the best results.

There are a wide variety of laser eye treatments, but the most common ones include:

  • LASIK: During this surgery, the doctor uses two lasers to cut up a thin flap in the cornea and then fold it back. A laser is then used to reshape the structure of the cornea and the flap that was folded over before will be placed back over the cornea for it to heal on its own.
  • LASEK: After giving drops to dissolve the surface cells of the cornea, the laser is used to reshape the cornea by using an excimer laser that allows light rays to enter the eye so that they can focus on the retina normally.

After the procedure is finished, it is likely for patients to experience watery and itchy eyes as well as blurred vision. Doctors can prescribe medications or eyedrops for pain relief and may also recommend you wear a protective shield over your eyes so that dirt and germs cannot enter them and cause infection. In order for your vision to perfectly stabilize, at least a three-month recovery time is needed and frequent checkups with your ophthalmologist are required to ensure that your eyes are healing properly.
