LASIK or PRK Eye Surgery

What is laser surgery?

The term “laser eye surgery” refers to the process of altering the shape of the front of your eye in order to improve your eyesight. However, although laser surgery is intended to be a “permanent” treatment, your eyes change as you age, and someone who gets laser surgery in their twenties or thirties may still require reading glasses or further surgery in later life. Any surgical procedure carries a tiny risk of adverse effects, so seek medical guidance before choosing that laser eye surgery is the best option for you and your situation.

What are the many forms of laser surgery available?

Over the last fifty years, eye laser surgery to enhance your vision has advanced at a remarkable pace. Using the first approach, known as radial keratotomy, doctors made radial cuts on the front surface of the eye in order to alter the shape of the eyeball. Although this increased eyesight, it had the unintended consequence of causing glare. It was in the 1970s, 1980s, and 1990s that researchers discovered a new type of laser that could be used to shave a very thin layer away from the front surface of the eye, altering the way the light was bent as it entered the eye and allowing for a more focused image. 

What is laser surgery?

This procedure is referred to as Photorefractive Keratectomy (PRK). Because the front surface cells of the eye were destroyed during the procedure, individuals reported discomfort following the procedure. It was also developed another technique called LASIK (Laser-Assisted In Situ Keratomileusis), also known as “flap & zap,” which involved cutting a thin flap from the front surface of an eye that could be replaced after laser eye surgery, reducing pain and discomfort while also improving vision immediately after the procedure.

What exactly is LASIK?

The photorefractive keratectomy (PRK) surgery was the first successful laser vision correction procedure to be performed on humans. LASIK, on the other hand, is becoming increasingly popular since it provides better rapid results with less pain than other procedures. However, the results are comparable, and it is speculated that nerve regeneration on the surface of the eye may occur more quickly with PRK than with LASIK, reducing the likelihood of difficulties during recovery. 

If your cornea is too thin for LASIK surgery, PRK may be a better option for you. While every laser eye surgery strives to give a ‘permanent solution, your eyes change as you grow older, and someone who has laser eye surgery in their twenties or thirties may still require reading glasses or further surgery in later years. Any surgical procedure carries a tiny risk of adverse effects, so seek medical guidance before choosing that laser eye surgery is the best option for you and your situation.

What is the procedure for using intraocular lenses to improve vision?

Artificial lenses may now be surgically implanted into the eye in order to increase one’s ability to see well. It is possible to implant a sort of lens in front of the iris, leaving your native lens behind the iris in some cases. The removal of your natural lens and the replacement with an artificial lens of a different shape is a distinct approach that can be used. This procedure, according to the Royal College of Ophthalmologists, is preferable to LASIK for the treatment of greater refractive defects and for individuals over the age of 50. Inquire with your consultant about which therapy is most appropriate for you. 

While this type of laser eye surgery is intended to be a “permanent” cure, your eyes change as you age, and you may require reading glasses or more surgery in later life. Adding an artificial lens has higher risks than laser eye surgery to the front of the eye, so consult with your doctor before deciding if laser eye surgery is the best option for you. Any surgery carries a risk of side effects, and adding an artificial lens has higher risks than laser eye surgery to the front of the eye.

What you probably didn’t know about laser eye surgery

Laser eye surgery, sometimes known as LASIK surgery in some circles, can be used to repair a variety of vision problems. However, there are certain risks associated with the operation, and not everyone is a candidate for it. In addition, depending on where a person lives, the procedure might be rather expensive.

The cornea is the outer covering of the eye that protects it from the environment. Astigmatism and myopia are both conditions in which the shape of the cornea can alter in some individuals, resulting in vision problems. In laser eye surgery, this layer is reshaped with the use of laser energy.

What you probably didn’t know about laser eye surgery

The precise way in which laser eye surgery reshapes the cornea is determined by the eyesight problem that the procedure is intended to remedy. Laser eye surgery may correct a variety of visual problems, including nearsightedness and farsightedness.

It takes only a few minutes, and the patients stay conscious during the operation. There are no known consequences. It is also normally painless — if a person suffers discomfort, it is usually a sign that there are difficulties.

This page describes what laser eye surgery is, who it can benefit from, how much it costs, how long it takes to complete, how long it takes to recuperate, and whether or not there are any related short- and long-term hazards.

What is laser eye surgery and how does it work? (LASIK or PRK)

When it comes to refractive cataract surgery Brisbane, LASIK (laser-assisted in situ keratomileuses) is the most often performed procedure. LASIK surgery was initially patented in 1989 and has since grown to become the most frequent therapy for refractive eye problems, according to Trusted Source. During the operation, lasers are used to reshape the cornea.

It is estimated that over 150 million Americans need corrective eyeglasses to compensate for refractive problems. This figure comes from the American Academy of Ophthalmology.

Refractive errors arise when the eye fails to bend — or refract — the light in order for it to correctly concentrate on the retina at the back of the eye, which is called a refractive error. This is most often caused by the shape of the corneal surface.


Farsightedness is referred to as hyperopia in the medical community. People who suffer from this illness may see items well in the distance, however other objects can look hazy when they are close to them. Farsightedness is caused by the cornea’s curvature being too flat, which causes it to be too thin. A steeper curvature in the cornea can be achieved with laser eye surgery, which can treat this condition.


Nearsightedness, often known as myopia or short-sightedness, is a condition in which a person can see clearly items that are close to them. Distanced objects, on the other hand, may look fuzzy. This is due to the cornea’s curvature is excessively steep, which causes the problem. By reshaping the cornea using laser eye surgery, healthcare practitioners can treat this condition.


Astigmatism is characterized by the presence of an irregularly shaped pupil in the eyes of those who suffer from it. The eye of someone who does not have the disease is spherical, like a soccer ball, however, the eye of someone who has the ailment may have a more football-like form. The abnormal curvature of the cornea can be corrected by laser eye surgery in some circumstances, although it is not always achievable. You can know about What is laser surgery? by clicking here.
