What is the difference between Lasik’s and Contoura’s vision?



Topography-guided LASIK surgery also referred to as Contoura Vision surgery. This procedure an upgraded variant of LASIK and offers surgically improved benefits for individuals considering having their glasses removed. This procedure works well for ordinary individuals and produces positive outcomes in patients who were ineligible for LASIK surgery because of defects in the cornea. The USFDA has given the technology permission to remove the specifications.

Contoura Vision: What Is It?

Contoura Vision a highly sophisticated, precise, and customised LASIK procedure. The cutting-edge technology gives surgeons an accurate, detailed picture of the cornea, enabling them to provide each patient with individually tailored care for their eyes. Over 22,000 different elevation points on the cornea examined and supplied to the surgical planning computer, which then directs the laser beam to correct the little changes in curvature at each end.

Thanks to its cutting-edge, customised design, Contoura Vision patientsquestionably more excellent vision than ever with eyeglasses or contact lenses. Topography-guided LASIK also focuses on anomalies affecting the surface texture of the cornea, in contrast to traditional LASIK, which corrects refractive problems by altering the overall shape of the cornea. 

Evolution of Laser Vision Correction

  1. 1987 – PRK is a first-generation laser eye procedure (Photorefractive Keratectomy)

The first attempt by humans to use lasers to correct vision called PRK. Currently, PRK employed in specific situations, including SMILE re-treatments and thin corneas. In PRK, no flap made; instead, the laser administered straight to the cornea’s surface. Recovery after PRK is complex and occasionally painful. Additionally, the recovery drawn out and takes 10 to 20 days to complete. Despite the prolonged healing time and discomfort, it frequently viewed as a cost-effective approach. Today, it not frequently practised.

  1. 1992 – LASIK is a second-generation laser eye procedure (Laser-Assisted Stromal In-situ Keratomileusis)

As a method of corneal flap surgery, Lasik was first developed. The corneal flap offers a natural bandage to the surgically exposed corneal surface, resulting in a quicker and safer visual recovery. The corneal flap traditionally made using a specific blade for more than 25 years of conventional LASIK. The more recent “Blade-Less LASIK” procedure performed more than ten years ago.

  1. 2012 – SMILE is a third-generation laser eye procedure (Small Incision Lenticule Extraction)

It is based on the femtosecond laser-assisted minor incision lenticule (corneal tissue) extraction technique. A femtosecond laser, which the only laser utilised in SMILE technology, used. To correct vision, laser slices away a piece of tissue called a lenticule, which then taken out through a tiny incision.

SMILE has used for approximately eight years but only recently received US-FDA approval in 2017. Since SMILE’s findings for Hyperopia and Astigmatism are inconsistent, the technology now employed only for Myopic corrections until further study conducted to allow for full utilisation.

  1. 2016 – Contoura Vision is the fourth generation of laser eye surgery.

The most recent advancement in bladeless LASIK is Contoura Vision. Compared to LASIK and SMILE, it has two more benefits.

  • Contrarily to LASIK and SMILE, Contoura Vision also corrects corneal abnormalities and LASIK & SMILE target the Pupillary Axis; it targets the Visual Axis (the eye’s natural seeing axis). 

What Distinguishes Lasik Surgery From Contoura Surgery?

The following are some of the distinctions between LASIK and Contoura vision surgery:

  1. More remarkable outcomes: When it comes to improving visual clarity and correcting refractive error, Contoura surgery produces better outcomes than LASIK. Some of the patients report revisions that are superior to 6/6.
  1. Broader scope: Contoura can be used to treat abnormalities in the corneal curvature in addition to vision correction.

Modern technology: Compared to traditional LASIK surgery, Contoura surgery uses more modern technology.

  1. Fewer problems: Compared to traditional LASIK surgery, Contoura vision surgery has fewer difficulties. The tissue sustains relatively less injury and heals more quickly.

Both techniques are advanced laser eye surgery used to treat astigmatism, short-sightedness, and long-sightedness. When it comes to the actual processes and the results, they do differ slightly from one another. 

Here are a few reasons that LASIK and Contoura are different from one another.

Although LASIK is a top-notch technique that can help patients stop wearing eyeglasses or contact lenses, the Contoura Vision process offers higher visual acuity and refractive results in many circumstances. Additionally, Contoura Vision uses a computer-guided topographic mapping method to map the cornea’s small contours. 

Optics and abnormalities in the cornea’s curvature can both be treated with Contoura Vision. This uneven curvature is typically the underlying cause of eyesight problems. While conventional LASIK procedures solely focus on the pupil, this therapy also targets the eye’s visual axis.

The outlines of the cornea generated by the computer analysis are programmed into a specially created laser for your vision correction when your ophthalmologist uses Contoura Vision. No two treatment programs are the same because every patient’s eyes are unique.

After Contoura Vision surgery, the cornea’s imperfections smoothed out, and the optical quality is so perfect that light may enter the eye uniformly. The patient now has a crisp, clear vision as a result. The Contoura Vision procedure offers more for patients than giving them a way to correct their vision without the use of glasses or contacts. After receiving therapy, many patients report seeing more clearly than they did while wearing corrective lenses. Patients now find driving at night simpler and performing other daily tasks without using corrective lenses.

The outcomes of contoura eye surgery are astounding. Additionally, by reducing tissue irritation, this treatment promotes a quicker recovery. In some circumstances, you can also utilise contoura vision to treat patients who underwent LASIK surgery but dissatisfied with the outcome.
