Contoura Vision Topography Guided Laser Correction – The Latest & The Safest way to Get Rid of Glasses

Posted on September 30, 2017

If you wear eyeglasses or contact lenses and want to be rid of external vision aids, there is a help. Contoura Vision Topography-Guided Laser Correction is a type of laser vision correction surgery that maps the unique topography of the eyes of each patient. The result is 6/6 vision or better for 92.6 percent of patients who undergo the procedure. The technique has been used outside the United States for more than 10 years and was approved in 2016 by the U.S. Food and Drug Administration (US-FDA)

Innovations in correcting vision have been around for centuries. Eye glasses were made as early as the 13th century in Europe. Contact lenses were made in the late 1800s from hand-blown glass in Switzerland. New innovations in correcting refraction errors continued to be developed. In the 1970s, a Russian ophthalmologist developed radial keratotomy, a surgical procedure to treat short-sightedness. In RK, incisions are made with a diamond knife from the centre of the cornea to the periphery to alter the cornea’s curvature. RK is still used today to treat certain types of astigmatism.

Contoura Vision Eye Surgery in Delhi

In the late 1980s, several ophthalmologists used excimer lasers to reshape the contours of a human eye. This technique, called photorefractive keratectomy, was approved in the early 1990s by the U.S. FDA. Since that time, PRK laser-assisted eye surgery has allowed more precise, longer-lasting corrections to refractive errors.

LASIK, which stands for laser-assisted in-situ keratomileuses, has refined the techniques of RK and PRK. During LASIK surgery, a small flap of the cornea is raised to allow reshaping of the underlying cornea tissues. The flap is replaced after surgery. LASIK surgery is the most common corrective refraction surgical procedure in the world used to correct astigmatism, short-sightedness and long-sightedness.

In 1999, doctors developed wave front analysis, which maps the errors of a patient’s eye as a whole. The data are programmed into the laser, resulting in a customised procedure with much better results. Contoura Vision builds on the principle of topography, providing precise mapping of 22,000 points of the cornea. Traditional LASIK wave-front maps approximately 200 points of the entire eye.

Not all patients are candidates for LASIK and Contoura Vision treatment. A qualified ophthalmologist must conduct a thorough eye exam and health history to make sure a patient will benefit from the procedure. At Eye7 Chaudhary Eye Centre in New Delhi, Dr Sanjay Chaudhary and his team of eye specialists evaluate the unique eye conditions of each patient and recommend a treatment plan that will provide the best vision outcome.

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 vision acuity and refractive outcome in the great majority of cases.

About Contoura Vision

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 was approved in 2016 by the FDA after three years of clinical trials. It has been used outside the U.S. for more than 10 years.

The technique works well for people who are long-sighted, short-sighted or have short-sightedness with astigmatism. This procedure treats irregularities of the curvature of the cornea as well as optics. Irregularities in curvature of the cornea are often the underlying cause of vision problems. The treatment is centered on the visual axis of eye. In contrast, other LASIK procedures are centered 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 eye glasses. 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 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. In addition, 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.


There are two main types of LASIK surgical procedures. The main difference is whether the surgeon uses a bladeless or a standard LASIK process. In the standard process, a specialised blade called a microkeratome is used to cut a thin flap on the front of the cornea. The underlying corneal tissues are then treated with a laser to correct vision.

There are several types of blade LASIK surgeries. The main difference between them is the thickness of the flap that is cut. The finer the procedure, the thinner the flap. A thicker flap affects the depth of remaining tissue that a surgeon can work with for vision correction. Depending on the amount of correction required for good vision, the surgeon may recommend a particular type of LASIK treatment. Because the thickness of the cornea may be altered by the treatment, the recommendation will be based on the characteristics of the patient’s cornea and the amount of correction required to achieve good vision outcomes.

There are several types of bladeless LASIK treatments. With bladeless LASIK treatment, an ultra-thin flap is cut using a femtosecond laser instead of a microkeratome blade. The femtosecond laser is the most advanced type of laser used in eye care, with speed measured at one quadrillionth of a second. After the flap is made, an excimer laser is used to reshape the cornea and correct vision. Bladeless LASIK preserves more tissue and has a faster healing time. It can also increase the level of customization and vision correction.

In all LASIK procedures, the flap naturally reseals itself after surgery. Both types of LASIK surgeries have been approved by the FDA and result in successful vision correction. After an evaluation, the doctor will recommend a treatment that can produce the best outcome for vision. Bladeless and standard LASIK treatments correct vision on the axis of the pupil. This is a major contrast to Contoura Vision, which corrects irregularities in the cornea and results in better vision.

To be eligible for any LASIK treatment, patients must:

  • Be at least 18 years old.
  • Have had a stable prescription for corrective eye-wear for at least one year.
  • Not suffer from dry-eye syndrome.
  • Fall within specific parameters of long-sightedness, short-sightedness, astigmatism or a combination of short-sightedness and astigmatism.
  • Not have any ocular surface diseases.
  • Have a suitable corneal thickness and curvature.
  • Not be pregnant or breastfeeding.

Contoura Vision Eye Surgery Cost in Delhi

As you consider your vision correction needs and confer with your doctor about which procedure will produce the vision correction that you want, cost will inevitably be a factor in making your decision. The cost of any LASIK procedure is dependent on the complexity of the treatment recommended. However, when you compute expenses associated with vision correction using contact lenses or glasses, LASIK surgery can actually save you money over time.

If you wear contact lenses, you must bear the cost of the lenses as well as the cleaning solutions, eye exams and backup spectacles. If you wear glasses, costs include not only annual eye exams but also frames and lenses. If you care about your looks and go for designer frames, thinner lenses, safety glass and lens coatings, the cost of a pair of spectacles can easily exceed the lowest-priced LASIK procedure. In general, blade LASIK procedures cost less than other types of LASIK treatments. The least expensive LASIK surgery costs approximately ₹20,000.

Contoura Vision laser correction costs the most of all LASIK surgeries. This is, in part, because the technology is the most advanced and requires specialised equipment. However, the cost also includes the expertise and training of the ophthalmologist doing the surgery. Only a few eye specialists in India have the training and experience to do this specialised procedure. Currently, Eye7 and AIIMS offer this procedure in New Delhi. Elsewhere in India, L.V. Prasad Eye Institute in Hyderabad, Sankara Nethralaya in Chennai and Narayana Netralaya in Bangalore also offer Contoura Vision LASIK surgery.

It’s hard to put a price tag on a procedure that is customised to each individual and involves state-of-the-art equipment and medical expertise. However, a survey of fees for Contoura Vision surgery in Delhi showed that there is not much difference in cost between Contoura Vision and bladeless LASIK surgery for a far superior outcome of vision correction. A bladeless LASIK procedure in Delhi may vary in cost between ₹75,000 and ₹90,000. Fees for Contoura Vision correction range between ₹95,000 and ₹1,15,000 in Delhi. Of course, exact cost will vary according to the complexity of each case and the procedure used.
