LASIK surgery is a type of corrective laser eye surgery that is becoming more popular worldwide. This easy, safe, and quick process may improve the quality of your eyesight. Patients previously relying on glasses or contact lenses will no longer require them in many situations.
Nonetheless, undergoing surgery on their eyes is daunting for many individuals. However, by knowing exactly what to expect before and after LASIK eye surgery, you may feel more at ease. Read this article thoroughly, and then talk to the best laser eye surgeons about your conditions and expectations.
What is LASIK?
LASIK eye surgery is a laser refractive procedure to treat vision issues and an option for glasses or contact lenses. In LASIK surgery, the cornea—the transparent tissue that forms a dome in front of your eye—is carefully reshaped to enhance vision.
The cornea accurately bends (refracts) light onto the retina. However, farsightedness, nearsightedness, or astigmatism cause the light to be bent improperly, causing hazy vision. Although vision correction using glasses or contact lenses is an option, reshaping the cornea will also provide the required refraction.
People should undergo a thorough evaluation to determine whether they are appropriate candidates for LASIK surgery. Before your examination and operation, you must entirely cease wearing contact lenses since they might alter the curvature of your cornea. Based on the variety of contacts you use and how long you've worn lenses, your doctor will give you precise instructions.
Your eye doctor will examine your medical and surgical history during the evaluation to examine your eyesight and determine if you can have the treatment safely. They will also do a thorough eye exam. The best laser eye surgeons will check for signs of:
- Eye infection
- High eye pressure
- Large pupils
- Dry eyes
Your eye doctor will evaluate your cornea's thickness, shape, and any anomalies. The specialist will assess the parts of your cornea that require shaping and calculate the precise volume of tissue that has to be excised from your cornea.
Before doing LASIK surgery, the best doctor for laser eye surgery often thoroughly evaluates your eye using wavefront-guided technology. In this exam, a scanner builds a very comprehensive chart of your eyes that resembles a topographic map. Before the treatment, your doctor will go through the advantages and disadvantages of LASIK and expectations for before and after LASIK eye surgery.
The procedure should take maximum 30 minutes. Your doctor will make you lie on your back in a reclining chair in a room with laser equipment. A big machine with a microscope and a computer screen is part of the laser system. A numbing drop will be given into your eye, the area around your eyes will be sanitised, and a lid speculum will be used to keep your eyelids open.
By using mechanical microkeratome, a ring will be placed over your eye, and extremely high pressures will cause suction on the cornea. During this procedure phase, the suction ring may impair your vision, and you may experience pressure and pain. A suction ring holds the microkeratome, a cutting device to carve a flap in your cornea. After that, the microkeratome and suction ring are both removed.
To cut a flap on the cornea, the best doctor for laser eye surgery may use a laser keratome (a laser instrument) rather than a mechanical microkeratome.
A see-through plastic plate is used to flatten the cornea when a laser keratome is employed. During this treatment portion, your vision may darken, and you may feel pressure and discomfort. Laser radiation is targeted into the cornea tissue, causing millions of microscopic gas and water bubbles to expand and join, separating the tissue beneath the cornea surface and forming a flap.
You can see things, but you will have varying degrees of hazy vision throughout the remainder of the treatment. The doctor will fold the flap back on its hinge and dry the exposed tissue. When the laser activates, this light will assist you in keeping your gaze fixated on a single point.
Your doctor will activate the laser after your eye is properly positioned. As the laser eliminates corneal tissue, some people might experience a burning hair-like odor. A computer handles the laser energy provided to your eye. The flap is re-positioned after the laser energy pulses vaporize the corneal tissue.
A shield is used for protection after the surgery. It is advised to wear this shield while sleeping to prevent rubbing your eye and putting pressure on it and protect your eye from being bumped or poked accidentally until the flap heals. If you require LASIK surgery in both eyes, physicians will usually perform the treatment on the same day.
Your eye may burn, itch, or feel like something is in it immediately after surgery. You may feel some discomfort or, in some situations, minor pain, and your doctor may advise you to take a painkiller. Your eyes may tear up or water, and your eyesight will almost certainly be foggy or blurry. You'll want to rub your eye, but don't! Rubbing your eye may dislodge the flap, necessitating further treatment.
Furthermore, you may suffer light sensitivity, glare, starbursts, or haloes around lights, or the whites of your eyes may seem red or bloodshot. These symptoms should resolve significantly within the first few days following surgery. If you suffer significant pain or your eyesight deteriorates rather than improves, you should reach your doctor immediately.
You should see your doctor within 2 days of surgery and then at regular gaps for the next six months. Your doctor will test your eyes before and after LASIK eye surgery, and inspect your eye at the first postoperative appointment. To prevent infection and inflammation, the best laser eye surgeons may prescribe one or more eye drops for you at home. Artificial tears may also be prescribed to assist in lubricating the eye. Even if your vision is blurry, do not continue wearing a contact lens in the operated eye.
To help prevent infection, you should avoid applying lotions, creams, or make-up around the eyes for up to two weeks following surgery or unless your doctor recommends you differently. Your doctor will advise you to keep washing your eyelashes for a while following surgery. For 1-2 months, you should also avoid swimming and utilizing hot tubs or whirlpools. Protecting your eyes from foreign objects and potential impact or bumps.
Millions of individuals throughout the world no longer need to wear glasses as a result of LASIK. Since its commencement many decades ago, the results of LASIK surgery have improved. Newer types of surgery have emerged due to new sophisticated technology, and surgeon skills have also improved. All of this should provide some confidence to anyone considering LASIK surgery who needs clarification about definite expectations.
