What exactly is PRK?

What exactly is PRK?

Posted on November 25, 2021November 25, 2021

PRK (photorefractive keratectomy) is a laser eye surgery that corrects refractive vision defects by altering the curvature of the cornea. It is the most often performed laser eye surgery. Because the cornea is in charge of refracting (or bending) light in the direction of the center of the retina, it is possible for refractive errors to occur when the shape of the cornea causes the refraction to be off-center.

PRK modifies the shape of the cornea, allowing it to bend light in the proper direction. It is a successful therapy for myopia (nearsightedness), hyperopia (farsightedness), and/or astigmatism, among other conditions.

PRK was the first laser refractive best laser eye surgery procedure to be authorized by the Food and Drug Administration (FDA) in 1995. Following that, LASIK was authorized, and today there are many other forms of laser vision operations offered to the public. In some cases, PRK can be a safe and effective alternative to LASIK for those who are not perfect candidates for the procedure.

Candidates for PRK positions and the criterion for selection

Laser eye operations such as PRK, LASIK, LASEK, and other types of laser eye surgery are conducted using somewhat different methodologies. In addition to recovery time and expense, these strategies may help you decide if one type of laser eye surgery is a better choice for you over the other type of laser eye surgery.

For example, in order to get access to the cornea, PRK totally destroys the epithelium, after which the epithelium regenerates. Instead, in LASIK and some other forms of eye surgery, a flap is formed in the epithelium and a portion of the cornea. The flap is folded back in preparation for the operation and then repositioned thereafter.

In part due to the fact that no flap is formed during PRK, it is frequently advised for those who have extremely thin corneal tissue. It can also be a useful option for people who suffer from dry eyes, as the flap approach has been shown to make dry eye problems worse in certain cases.

PRK may also be a preferable alternative for persons who are at higher risk of eye damage, such as those who participate in sports or work in hazardous environments. Even after the injury has healed, being hit or poked in the eye might cause the flap to shift out of place.

Candidates for laser eye surgery must satisfy specific requirements, such as being in overall excellent eye health and having a stable lens prescription, in order to be considered. Having PRK or other laser eye operations will not stop the progression of myopia or hyperopia that is already present. If your lens prescription has not been consistent for at least a year before laser eye surgery, your eyesight may deteriorate as a result of the procedure itself.

The fact that PRK will neither prevent nor correct presbyopia, the age-related loss of near vision that occurs around the age of 40, is also crucial to remember. Wearing reading glasses for close-up jobs is the most convenient approach for the majority of people who acquire presbyopia following PRK.

For an eye doctor to determine whether or not you are a candidate for PRK, you must have a full eye exam. The doctor will examine you to ensure that you satisfy all of the requirements and then assist you in determining whether or not PRK is suited for you.

What is the procedure for doing PRK?

Numbing drops will be placed in your eyes by your eye surgeon or another qualified eye care practitioner at first. Whether you’re feeling worried, they could also ask if you’d want to take a light sedative with you.

After that, your surgeon will place a speculum over your eyes to prevent you from blinking anymore. Some PRK surgeons additionally employ the use of a suction ring to keep the eye motionless throughout the procedure. Even while the suction ring will exert some pressure on your eyeball, the numbing drops will prevent you from feeling any other sensations in the eye.

Following that, your surgeon will remove the epithelium, the very top layer of corneal cells, in order to have access to the next corneal layer. A surgical instrument, an alcohol solution, or a “buffing” equipment will be used to remove the growth, depending on the surgeon’s preference.

Following the removal of the epithelium, you will concentrate on a target light. In the meanwhile, the surgeon will use an incredibly accurate, computer-controlled excimer laser to reshape the cornea while you are focused on it. This laser eliminates minuscule quantities of tissue from the cornea in order to establish the precise corneal shapes required for sharp eyesight …
