What You Should Know About Laser Refractive Surgery

Laser refractive surgery from Kraff Eye Institute for example is a procedure that aims to correct refractive errors (myopia, hyperopia, and astigmatism) to reduce or eliminate the need for glasses and contact lenses. The surgery can be done by applying different surgical techniques. The most used are LASIK and PRK.

What is LASIK?

LASIK from PRK Surgery Center in Evanston for instance is the most used technique in the world for laser degree correction, both for myopia and hyperopia, astigmatism, and some presbyopia cases. An ultrathin cut is made in the anterior layer of the cornea, which allows the laser to be applied to its inner layer. Therefore, there is less surface area to heal, less postoperative discomfort, and visual recovery is usually quick.

What is PRK?

In PRK, grade correction is performed by applying the laser to the cornea’s surface. This treatment is indicated for patients who have thinner, asymmetrical corneas or are generally younger. It is a very safe technique, but visual recovery is slower. In the postoperative period, it is essential to avoid exposing the eyes to the sun for 1 year after surgery.

Will You Feel Pain In Refractive Surgery?

Regardless of the surgical technique (LASIK or PRK), most patients report only some discomfort, sometimes a feeling of sand in the eyes and tearing, which will disappear quickly. In PRK, postoperative discomfort is usually greater than in LASIK. We warn that using the medicines according to the medical prescription is extremely important.

What Are The Benefits Of Laser Surgery?

  • More comfort
  • No need for a tampon or dressing
  • No need for stitches
  • Anesthesia with eye drops
  • No need for hospitalization
  • The average duration of the surgery is 15 minutes, but the application of the laser is only a few seconds, according to the degree to be treated
  • The person will be able to work the day after the surgery, depending on the conditions of the work environment (no pollution) and if they feel able to perform the activities. There are cases where glasses or contact lenses remain the best resource. In around 5% of cases, there may be a residual degree, which requires a new laser application

What Are High-Grade Phakic Lenses?

Artisan or arti-flex phakic lenses are implanted in the eyes and fixed in the iris (eye color) to correct Myopia, Hyperopia, and Astigmatism when laser refractive surgery cannot be performed. This usually occurs in higher grades and thinner corneas.

Post-Implantation Of Arti-Flex Phakic Lenses

These lenses allow the correction of approximately 20 degrees of myopia, 10 degrees of hyperopia, and 7 degrees of astigmatism. The surgery is performed under local anesthesia, without hospitalization, and visual recovery begins within the first 24 hours.
