Difference between Contoura Vision and LASIK

Both LASIK and Contoura Vision are state-of-the-art techniques used to correct short-sightedness, long-sightedness, and astigmatism. There are differences between the two types of surgeries in both procedures and visual outcome.

  • Although LASIK has been the gold standard to eliminate the need for spectacles or contact lenses, the Contoura Vision procedure gives better visual acuity and refractive outcome in the vast majority of cases.Contoura Vision takes LASIK corrective surgery to a new height. Contoura Vision is a computer-guided topographic mapping technique that maps microscopic contours of the cornea. The cornea is the clear front of the eye.
  • This procedure treats irregularities of the curvature of the cornea as well as optics. Irregularities in the curvature of the cornea are often the underlying cause of vision problems. The treatment is centred on the visual axis of the eye. In contrast, other LASIK procedures are centred on the pupil.
  • With Contoura Vision, the contours of the cornea generated by the computer analysis are programmed into a specially designed laser used for this procedure. At least 22,000 points of the cornea are mapped. An individualised treatment plan is made, and the laser applies this treatment to the cornea. Because each patient’s eyes are different, no two treatment plans are alike.
  • The irregularities of the cornea are smoothed, and optical quality becomes so perfect so that light penetrates the eye evenly. This results in clear, sharp vision. The technique goes beyond the standard corrections of eyeglasses. Most patients see more clearly without spectacles after treatment with Contoura Vision than they did with corrective lenses. There are also significantly fewer problems with glare and halos around lights. Studies show a decrease in complaints by patients about the difficulty in driving at night.
  • The results of Contoura Vision correction are exciting. Approximately 65 percent of the patients who had the treatment have correction better than 6/6. Also, there is less damage to tissues and faster healing. Contoura Vision is also used in some instances to treat people who have had LASIK surgery and are not satisfied with the results.

2. ICL

What is ICL eye surgery?
An implantable collamer lens (ICL) is an artificial lens that’s permanently implanted in the eye. The lens is used to treat:

  • myopia (nearsightedness)
  • hyperopia (farsightedness)
  • astigmatism

Implanting an ICL requires surgery. A surgeon places the lens between the eye’s natural lens and colored iris. The lens works the eye’s existing lens to bend (refract) light on the retina, which produces clearer vision.
The ICL is made of plastic and a collagen called collamer. It’s a type of phakic introcular lens. “Phakic” refers to how the lens is placed in the eye without taking out the natural lens.
Though ICL surgery isn’t necessary to correct vision problems, it can eliminate or reduce the need for glasses or contact lenses.
