What Are The Different Types Of Eyesight Correction Surgery


With the active participation of eye specialist physicians and surgeons worldwide, vision correction operations or different types of laser eye surgery have vastly advanced over the previous 25 years. As a result, people no longer have to rely on eyeglasses and lenses for the rest of their lives since laser treatment, and other surgical procedures allow them to live a whole life while maintaining long-term clear vision or eyesight. We’ve included a few popular and successful vision correction operations below, each of which is great in its field.

Radial Keratotomy

During the 1980s in the United States, radial keratotomy was one of the most common laser eye surgery types to correct nearsightedness. An incision is made on the eye’s surface to flatten it during this surgical procedure. Patients with lesser prescriptions benefited from this eyesight correction procedure. However, its popularity has dwindled due to long-term adverse effects like night vision problems, wavering vision, relapse, substantial glare, and so on that some people (with a high prescription) have experienced. The RK surgical procedure is now nearly obsolete because of introducing a new and improved kind of vision correction treatment.

Photo refractive Keratectomy

The first effective laser vision correction operation, Photorefractive Keratectomy, is used to modify the cornea’s curvature this procedure. This surgical operation takes the thin issue directly from the eye’s surface. Surface Ablation is another name for PRK. Although this vision correction procedure is still performed, it is not as popular as more modern surgical treatments such as LASIK. However, PRK is believed to be safer than LASIK surgery in other ways. When it comes to LASIK surgery, if the person’s cornea is still very thin, the procedure is tough and hazardous. There is no chance of forming a thin layer with PRK.

LASIK (Laser In-situ Keratomileusis)

The LASIK surgical procedure is used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. The cornea is reshaped during this operation so that the light passing through it may focus on the retina on the backside of the eye. Accuracy and modern computer imaging technology are employed in this surgical procedure to provide exact corneal pictures and additional treatment advice. The LASIK surgical procedure has various advantages, including minimal discomfort, no sutures or bandages, eyesight recovery the following day of treatment, necessary vision alterations modification feasible after many years, and patients’ reliance on contact lenses and glasses is reduced. However, in addition to all of these advantages, LASIK surgery is accompanied by some risks in rare circumstances. This operation is highly complicated, and in some cases, a flap generated by a doctor may permanently impair eyesight.

Lenticule Extraction with a Small Incision (SMILE)

Lenticule extraction with a small incision is a relatively novel method for correcting myopia. A laser generates a tiny disc of tissue within the inner layer of your cornea throughout the procedure. The surgeon then removes this tissue, known as a lenticule, from your cornea through a tiny incision. Because SMILE does not require a corneal flap, some doctors prefer it to LASIK. As a result, the cornea is more stable, and dry eye is reduced. Although SMILE is less intrusive, some surgeons believe the technique is still too young. To suggest SMILE over LASIK, more experience may be required.


Intracorneal Ring Segments, or ICR, is another name for Intacs vision correction surgery. First, a surgeon will create a tiny incision in the cornea in this treatment approach. After that, two crescent-shaped plastic rings are put at the outside border of the cornea to flatten it. Because of the flattened cornea, light rays penetrate the eye and concentrate differently on the retina. However, laser-based techniques for correcting moderate nearsightedness have largely supplanted ICR in recent times.

PRELEX (Presbyopic Lens Exchange)

A doctor implants multifocal lenses in the PRELEX vision correction operation to reestablish focus and improve flexibility that had previously shrunk due to losing the eye’s lens flexibility. Patients with presbyopia (the loss of flexibility in the eye lens) have difficulties concentrating on close things. But, with the help of PRELEX vision correction treatment, this problem is addressed.

Apart from these methods, there are certainly more types of eye surgery like Phakic Intraocular Lens Implants, Automated Lamellar Keratoplasty and Phakic Intraocular Lens Implants are known to correct your visions. All of these have their benefits and risks that can easily be avoided by consulting an expert eye surgeon for the treatment.
