Laser eye surgery, also known as refractive surgery, is a revolutionary medical procedure designed to correct common vision problems, such as short-sightedness (myopia), long-sightedness (hypermetropia), and astigmatism (blurred vision). This relatively simple and effective procedure reshapes the cornea, the clear “window” at the front of the eye” to improve how light enters the eye, resulting in clearer vision. 

Laser eye surgery has become an increasingly popular choice for people who want to reduce or eliminate their dependency on glasses or contact lenses. 

How Laser Eye Surgery Works

The procedure involves using a laser to reshape the cornea, the transparent surface at the front of the eye. The cornea plays a crucial role in focusing light onto the retina at the back of the eye, which in turn is responsible for sending visual signals to the brain. When the cornea is misshaped, light is not properly focused, causing your vision to be blurred.

In laser eye surgery, the eye surgeon uses a highly focused ultraviolet light-beam to remove tiny amounts of corneal tissue. This changes the shape of the cornea, improving the way light is bent (refracted) when it enters the eye. As a result, light is better focused onto the retina, giving you clearer and more accurate vision.

The Science Behind Laser Eye Surgery

The technology used in laser eye surgery operates with incredible precision, targeting tissue without damaging surrounding areas. The laser light removes microscopic layers of corneal tissue, which can be done in several different ways depending on the type of surgery chosen. The three most common types of laser eye surgery are LASIK, Trans-PRK (sometimes known as “Touchless Robotic”), and SmartSight (a keyhole “LALEX” procedure). All three procedures rely on the same basic principle of reshaping the cornea, but they differ in how the corneal tissue is accessed.

In LASIK surgery, a femtosecond laser is used to create a thin flap on the surface of the cornea. The flap is then lifted, and an excimer laser is used to reshape the underlying corneal tissue. After reshaping, the flap is put back in place, where it naturally adheres without the need for stitches.

In SmartSight surgery, a femtosecond laser is used to create a thin layer of tissue underneath the surface of the cornea, known as a lenticule. The laser then makes a microincision in the side, through which the surgeon removes the lenticule, thereby reshaping the cornea. The microincision naturally closes without the need for stitches, and once healed there is no vulnerability or indication it was ever made. 

In Trans PRK (Touchless Robotic), an advanced type of excimer laser removes the outer layer of the cornea (epithelium) using rays of light, before applying more light to reshape the underlying tissue. This method doesn't require a flap and doesn’t require any instrumentation to touch the eye, but because the epithelium has to regenerate, recovery can take a few days longer compared to LASIK or SmartSight.

The Benefits and Effectiveness of Laser Eye Surgery

Laser eye surgery offers numerous advantages for people struggling with vision problems. First and foremost, it provides a long-term solution to refractive vision issues, reducing or eliminating the need for corrective lenses. For many people, this means greater freedom and convenience, especially when engaging in activities like swimming, running, or traveling.

The procedure is also relatively quick, usually taking about 15 minutes per eye, and is minimally invasive. With modern technology and techniques, the chances of complications are low, and most patients experience significant improvements in their vision within a day or two of surgery.

In Australia, laser eye surgery has become widely available and is offered by many reputable clinics across the country. While the procedure is safe and effective, it is essential for patients to undergo a thorough eye examination to determine whether they are good candidates. Factors such as age, corneal thickness, and the overall health of the eyes are taken into consideration to ensure the best possible outcome.
