What is Laser Eye Surgery?

                                      What is Laser Eye Surgery?


Laser eye surgery that some individuals call LASIK surgery, will correct many eyesight conditions. However, there are potential side effects, and not everybody can have the procedure. The surgery also can be expensive, depending on wherever an individual lives.

The eye has an outer layer referred to as the tissue layer and is commonly called the cornea. Some people’s corneas go through changes in their shapes, resulting in vision problems, like astigmatism and short-sightedness. Optical laser eye surgery is a procedure performed to reshape this layer.

Precisely how optical laser eye surgery reshapes the cornea depends on the vision condition that the treatment aims to correct. Optical laser eye surgery will fix vision problems, like myopia and ametropia.

The surgery is fast and people stay awake throughout the procedure. It is typically painless-if someone experiences pain, it might be an indication of complications.

This article discusses what optical laser eye surgery is, who it will facilitate, how much it costs, what is the period of the surgery, recovery time, and any associated short- and long-run risks.

What is optical laser eye surgery?

LASIK stands for laser-assisted in situ keratomileusis and it is the most typical sort of refractive eye surgery. LASIK was initially patented in 1989 and has become the utmost common treatment for refractive eye errors. The procedure involves lasers that reshape the tissue layer i.e., the cornea.

Who could it help?

According to medical professionals, over one hundred fifty million Americans use corrective eyewear, like glasses or contact lenses, to make amends for refractive errors.

Refractive errors occur if the eye doesn't bend or refract- the brightness to properly target the membrane within the back of the eye. This often happens because of the shape of the cornea.

Clinically farsightedness is known as ametropia. Individuals with this condition will see

objects within the distance clearly, however different things will seem hazy at a close distance. Ametropia is because the curvature of the tissue layer is too flat. Optical laser eye surgery corrects this by reshaping the tissue layer by giving it a steeper curve.


Nearsightedness, referred to as myopia or short-sightedness, is a condition when someone will see objects near to them clearly. However, distant objects will seem blurred. This is often because the curvature of the cornea is too steep. Medical professionals will correct this through optical laser eye surgery by reshaping the cornea.

People with astigmatism have a differently-shaped eye that characterizes this condition. The eye of somebody not having this condition is spherical, similar to a soccer ball, whereas, with astigmatism, the eye might be similar to a football-like shape. It is attainable to correct this irregular curvature of the cornea with optical laser eye surgery in some cases.

Who is an unsuitable female candidate?

Women who don’t seem to be appropriate candidates for optical laser eye surgery include who:

  • Have had a modification within their eye prescription in the last twelve months
  • Take medications that will cause changes in vision
  • Are in their 20s or younger than that, though some specialists advocate not being beneath eighteen years 
  • Have skinny corneas, which cannot be stable following optical laser surgery
  • Are pregnant or nursing

Benefits of laser eye surgery

The main good thing about optical laser eye surgery is that most individuals are not required to wear corrective eyewear to see clearly. People might choose to go through the procedure for many reasons, including:

  • being unable to wear contact lenses however prefers to not wear glasses, maybe for cosmetic reasons 
  • wishing to undertake activities, like sports, that need someone to not wear glasses or contact lenses 
  • the benefit of not having to wear corrective eyewear

Risks and complications

A woman is in more a danger of developing complications if they have the subsequent eye conditions:

  • eye infections, like keratitis or ocular herpes
  • significant cataracts — women with this condition won't have corrected vision once optical laser surgery is performed
  • glaucoma
  •  large pupils
  • keratoconus, an illness that results in thinner and unstable cornea over time
As with all surgeries, there are certain complications, like:

  • Dry eyes: Up to 95 percent of individuals who have optical laser eye surgery might get dry eyes once the procedure is done, and the eyes produce fewer tears. Lubricating eye drops will facilitate this symptom.
  • Glare or halo: 20 percent of individuals undergoing optical laser eye surgery might have visual changes like glare, halo, or sensitivity to lightweight.
  • Double or hazy vision: As many as one in fifty individuals might report haziness and feel something in their eyes. Diffuse lamellar keratitis — usually referred to as “sands of Sahara” syndrome — is also the cause.

Other complications someone might get include:

  •  eye infection
  • corneal flap complications
  • red or bloodshot eyes.

Most symptoms ought to resolve after the initial days, thus a woman experiencing any symptoms after a point ought to check with her doctor.

What to expect throughout surgery?

The Food & Drug Administration (FDA) suggests optical laser eye surgery sometimes takes around thirty minutes. Others estimate the procedure can take around five minutes per eye.

People undergoing optical laser eye surgery ought to expect the following:

  • They will sit on a chair and recline so that they are flat on their back, beneath an optical laser device and display screen.
  • The surgical team cleans the part around the eye and places numbing drops inside the eye.
  • Surgeons use a lid speculum, an instrument that holds the eyelids open.
  • An optical laser will then cut a flap in the cornea, and the eye surgeon lift this open.
  • People will be required to stare at a light that will keep their eyes still whereas the optical laser works.
  •  The optical maser can then reshape the surface of the tissue layer.
  • The surgeon then places the flap into its position and applies a shield that protects the eye.

What is the recovery period?

The FDA notes that once the surgery is done, women might feel burning, itching in their eyes or that there is a foreign object. The doctor might prescribe a gentle pain reliever, like acetaminophen, to ease these sensations.

Surgeons can give women a protective eye cover to shield their eyes, as there'll be no stitches holding the flap in its position. The guard prevents the rubbing of the eye or accidentally applying pressure, like when asleep.

Women should sometimes take some days off from work so that they fully recover. They must schedule an appointment with their surgeon within 24–48 hours of the surgery to go through an eye examination. The doctor will then certify whether the eyes are healing as they should. After this, a woman will require to make further appointments over the first six months.

It may take up to six months for a woman’s vision to stabilize once optical laser eye surgery is done. After the surgery, they will notice their vision fluctuating for a moment however this should not be a cause for concern.

However, it's common for vision to fluctuate for the first few months after the surgery. Additionally, an optical laser eye surgery sometimes might accidentally over-o0072 under-correct a person’s sight. This may lead to another surgery to rectify the issue, which medical professionals sometimes referred to it as an enhancement.

You must remember that corrected vision can regress years after the procedure is done.

What is the cost of laser eye surgery?

The cost of LASIK surgery is going to vary according to where a woman might live. Different surgeons might use varied instruments or techniques, which might affect the cost.

Health insurance corporations sometimes categorize LASIK as an elective or cosmetic procedure and usually do not cover these treatments.

Although optical laser eye surgery can be costly, it's crucial that individuals completely do their research before going through the treatment at reduced costs. There may be some reasons for the reduced cost and this can increase the complications.

Laser eye surgery is also helpful for many women to solve problems with their sight. However, these enhancements will last for some years but they're not always permanent. It is quick however it can be a costly procedure that health insurance doesn't always cover.

It is vital to remember that this procedure might not correct hypermetropia — which is the need for reading glasses as women age. Women ought to discuss whether or not optical laser eye surgery is appropriate for their circumstances with their medical professionals.
