How does Topo-Guided PRK help improve vision?

Eyes are essential parts of one's life. Without proper vision, people can't lead normal life. Therefore, it is vital to keep your eyes healthy and fit at all times.


Choosing the best laser eye center in Delhi to treat your eye is crucial. Doctors at a reputable hospital will always provide the best treatment, including Topo-guided PRK, to help improve vision.


If you want to learn more about Topo-guided PRK, then read this post. In this post, we shall discuss everything about TG PRK.


What is Topography-Guided Photorefractive Keratectomy?


Photorefractive keratectomy is one of the best treatments for refractive errors, such as nearsightedness, farsightedness, and astigmatism. It is a surgical procedure that is used to change the shape of the cornea in order to correct vision issues.


During this procedure, the outermost portion of the cornea is removed. After that, a laser is used to change the shape of the cornea. In TG-PRK, corneal topography is initially utilized to generate three-dimensional maps of the surface of the cornea before the laser treatment is administered.


When this information is paired with the patient's refractive error, a precise and individualized plan for correcting the patient's eyesight using laser technology is developed.


What is Corneal Topography?


Corneal topography, also known as corneal topometry, is a computer-assisted diagnostic method that provides a three-dimensional map of the surface curvature of the cornea.


The cornea is the thin covering that covers the front of the eye and is an essential component in the eye's ability to focus images on the retina.


Vision is considered to be normal when the cornea is equally shaped. However, vision is said to be compromised if the cornea is abnormal, such as being overly convex, flat, or unevenly curved.


Corneal topography generates a precise and visually appealing map of the structure and strength of the cornea. This specific data is utilized diagnose, monitor, and treat a variety of eye disorders.


In addition to this, it is utilized in the process of fitting contact lenses and planning surgery, including the use of lasers to correct vision.


In the laser vision correction process, the corneal topography map is utilized in tandem with the results of other tests to find out exactly how much corneal tissue will be removed and which ablation pattern will be applied to the cornea.


How Does Topo-guided PRK Help To Improve Vision?


TG-PRK is an excellent procedure to improve vision. It helps people get rid of refractive errors, such as myopia, hyperopia, and astigmatism. It is an outpatient surgical procedure.

The procedure starts with the removal of a small section of the corneal coating, also known as the epithelium. This can be done with a surgical device or a specialized solution.


After the epithelium has been removed, a laser that has been programmed with the patient's topography and refractive measurements is used to carefully and precisely remove microscopic portions of the corneal tissue so that it can be reshaped. Doctors will then place lenses to protect the cornea.


It will take a few days for the patient to completely recover and get the perfect vision.

TG-PRK is also used to correct one of the chronic conditions known as Keratoconus. Keratoconus causes the cornea, the transparent dome-shaped surface of the eye, to thin out and protrude like a cone. This, in turn, results in light beams becoming out of focus, resulting in distorted and fuzzy eyesight.


The problem is that it becomes challenging for people with keratoconus to wear contact lenses or enhance vision by just wearing glasses due to the irregular shape of the cornea.

Topo-guided PRK procedure corrects the cone-shaped corneal abnormalities that are the root cause of impaired visual function.


Aside from these, TG-PRK is also used to treat corneal scarring and other corneal defects.
