LASIK surgery, known as laser eye surgery, improves vision. Individuals who are nearsighted or farsighted and those with astigmatism can benefit from LASIK surgery as a substitute for wearing eyeglasses or contact lenses. However, only some are good candidates for LASIK surgery.
The Vision Council states, “Over 195 million Americans have had some vision correction.”
This article will explain LASIK surgery, why it is necessary, and how it is performed. It will also take into account recovery times and aftercare.
What exactly is it?
LASIK surgery is a procedure that corrects flaws, or refractive errors, in the ability of the eyes to focus.
Primarily, It is an abbreviation for laser-assisted in situ keratomileusis.
Surgeons use a laser to reshape the cornea during the LASIK procedure. The cornea is like the clear, dome-shaped window that focuses light on forming an image on the retina.
Blurred vision occurs when the light passes through the lens and the tear film. And, importantly, when the cornea is not properly focused on the retina.
LASIK surgery alters how the eye focuses by reshaping the cornea, resulting in improved vision.
Why is it required?
Surgeons execute LASIK surgery to correct refractive or focusing errors. Most people can perceive clearly without glasses or contact lenses after the procedure.
If you have one of the following vision problems, LASIK surgery may be an option for you:
Nearsightedness
Nearsighted or shortsighted people can see closer objects more clearly than distant objects. Also, nearsightedness is known as myopia.
The National Eye Institute (NEI) states that nearsightedness occurs because the eyeball is too long about the cornea. Light focuses in front of the retina rather than on it, resulting in blurry distance vision.
Farsightedness
Farsightedness, also known as hyperopia, allows people to see distant objects more clearly while making nearby objects appear blurry.
It is due to the eyeball being shorter or the cornea being flatter than usual. Light focuses behind the retina rather than on it, resulting in blurry near vision.
Astigmatism
Light cannot be focused evenly at any distance if the cornea curves or flattens unevenly. Nearsightedness, farsightedness, and astigmatism are all possible.
You can use corrective lenses or have LASIK surgery if you have one or more vision problems.
Who is not a candidate for LASIK surgery?
According to the NEI, a person’s vision must be stable for LASIK surgery to be effective. Their eyeglass or contact lens prescription has remained consistent over time.
Some people are not candidates for LASIK surgery. A comprehensive dilated eye exam is required to determine whether or not the procedure is appropriate for them.
Some eye conditions, for example, may increase the likelihood of complications, including:
Dry eyes,
Glaucoma,
Big pupils,
cataracts,
Eye infections such as keratitis and keratoconus.
The LASIK Surgery Procedure
People should consult their eye doctor i.e. https://www.visualaidscentre.com/lasik-eye-surgery-in-delhi/ to ensure that LASIK surgery is a good option.
They will learn what to expect during the procedure and recovery process and will be able to ask any questions they may have.
How to Get Ready for LASIK Surgery
People can prepare for the LASIK procedure in a variety of ways.
Wearing contact lenses alters the shape of the cornea, influencing the results. As a result, people should start wearing glasses before having surgery.
People should refrain from wearing contact lenses during the following times before surgery, according to the Food and Drug Administration (FDA)Trusted Source:
Contact Lenses:
One should remove soft contact lenses for two weeks.
Also, remove toric soft or rigid gas-permeable lenses for at least three weeks.
Hard Lenses:
They should stop wearing hard lenses for at least four weeks before the initial evaluation.
Additionally, people should:
Wear appropriate clothing: Avoid lint-producing clothing, as the fibers may irritate the eyes.
Make transportation arrangements: Because people should not drive immediately after LASIK surgery, they must use alternative transportation to get home.
Avoid using makeup or lotions: Your eyes and face need to be clean and free of contaminants.
LASIK surgery is a quick procedure that only takes about 30 minutes.
Before the procedure, the doctor will thoroughly examine the person’s eye to rule out infection, inflammation, or abnormal eye pressure. Following that, the surgeon will take detailed measurements of the eye and cornea.
Although the patient will be awake during the procedure, the NEI notes that if they are nervous, they may be given medication to help them relax.
The patient will then recline in a reclining chair while the surgeon applies numbing drops to the eyes. They will use a device to keep the eyelids open.
A soft corneal suction ring will keep the eye in place, which may cause vision to dim. The eye surgeon will cut a hinged flap at the front of the cornea with a tiny blade. While the flap is folded back, the surgeon will use a laser to eliminate precise amounts of tissue and remodel the cornea.
The laser uses a system to track the eye’s position and redirect the laser’s pulses as needed. The flap will then be carefully repositioned over the cornea by the surgeon.
Without the use of stitches, natural adhesion holds the flap in place.
Aftercare
The FDA warns that a person’s eye may itch, burn, or feel like something is in it immediately following the procedure. They may also feel minor pain or discomfort.
People should avoid rubbing their eyes, as this can cause damage and necessitate additional surgery.
People may also encounter the following:
Sensitivity to light, glare, bloodshot eyes
These symptoms usually go away within a few days.
To protect their eyes, the person must immediately rest in a darkened room and wear dark glasses.
The eye doctor may prescribe antibiotics and anti-inflammatory eye drops for 5-14 days. Patients should also use preservative-free artificial tears to keep their eyes moisturized.
Some people may require protective goggles to protect their eyes while sleeping and to alleviate dry eyes.
Recovery Period
Although people can see after the surgery, it may take 3-6 months for the eye to heal completely, according to the FDA.
One must start non-contact sports three days after surgery. Also, start strenuous contact sports at least four weeks later. They should also refrain from swimming for 1-2 months.
Because infection prevention is critical, the doctor may advise waiting two weeks after surgery before using any cosmetic products around the eyes.
Conclusion
During LASIK surgery, the surgeon performs LASIK to rectify refractive vision errors. They will reshape the cornea and improve the eye’s focus during the brief procedure.
This treatment is not appropriate for everyone. However, for some people, having LASIK surgery could mean never wearing glasses or contact lenses again.
However, there exist some risks and complications associated with the procedure, which you should discuss with a doctor to ensure that this surgery is appropriate for them.
