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 though 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.

Is laser eye surgery a painful procedure?

The use of eye drops to administer local anesthesia will be used to alleviate any discomfort you may have during the procedure. It is possible to feel pressure when having LASIK surgery since the surgeon is cutting the corneal flap. Additionally, you may have some soreness or irritation for up to 24 hours following your laser eye surgery. As the surface of the cornea recovers after PRK, you may have discomfort for a week or longer after the procedure. During this time, you will be provided with eye drops to utilize to alleviate the discomfort.

What is the benefit of laser eye surgery in terms of improving my prescription?

For you to have a clear vision, the light that enters your eye must go to a certain location on the retina, which is located at the rear of the eye. The cornea, which is the transparent surface at the front of the eye, and the crystalline lens, which is located inside the eye, both bend (refract) light. Long- or short-sighted people may notice that the light does not come to a point in the proper location. In the case of laser eye surgery, the curvature of the cornea is altered, which modifies the way light bends in order to guarantee that it gets to a focus at the proper location.

I have astigmatism; will laser eye surgery be a good option for me?

Almost everyone has some degree of astigmatism, which is a condition in which the eye is more like a rugby ball than perfectly round. There are restrictions to treating astigmatism with LASIK because lasers may now be designed to reshape the cornea, although there are certain advantages to doing so. Astigmatism of fewer than 3.00 dioptres (D) can be treated completely with a single LASIK treatment, whereas greater degrees of astigmatism may only achieve partial correction or may necessitate further surgery. 

In addition, astigmatism might raise the cost of LASIK surgery. Because your eyes change with age, even if you get laser eye surgery in your twenties or thirties in order to achieve a “permanent” solution, you 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.
