Contoura Vision is the latest and most advanced technology designed to enhance vision. It involves the use of a diagnostic device called the Topolyser, which provides highly precise and accurate mapping of the eye with 22,000 unique elevation points per eye.
Launched in 2016 and FDA-approved, Contoura Vision can identify corneal irregularities and create a customized treatment profile for each eye. Unlike other laser platforms that operate on the pupillary axis, Contoura is the only platform in the world specifically designed to treat along the visual axis, resulting in the sharpest possible vision.
Narayana Nethralaya, a pioneer in eye care with state-of-the-art technology and some of the most experienced and world-renowned LASIK surgeons, was the first eye hospital to introduce Contoura Vision in Karnataka.
A detailed refraction and comprehensive ocular examination is performed by a refractive surgeon. This is followed by a battery of preoperative tests such as the corneal topography (Pentacam) to check for the curvature and thickness of the cornea. It helps in deciding if the patient’s eye is fit for LASIK and also in deciding the need for contoura. A dilated fundoscopy is done and retinal pathologies such as thinning/ hole/ tear if detected are found during the evaluation, are treated first using barrage laser. LASIK is then scheduled after 1 to 4 weeks.
On the day of the scheduled procedure, the patient’s topographic scans are done using topolyser. The customised treatment planning is then done based on these scans Contoura Vision Femto LASIK is performed using the WaveLight Refractive Suite, the most advanced refractive platform available in the world.
Bladeless Femtosecond technology (FS 200 laser) is used to create a thin flap, which is then lifted using the microsurgical instruments. Topoguided laser ablation for customised refractive correction is performed using the latest EX500 exicmer laser.
Following the procedure, the patient can go home after just 30 minutes. Post-operative medications and precautions are explained in detail through personalized counselling. Eye drops are prescribed to prevent infection and facilitate the healing process. The patient is scheduled for post-operative check-ups on day one and one month later.
At Narayana Nethralaya, we are committed to providing our refractive patients with advanced quality eye care at affordable prices. These eye surgery experiences stand testimony to the excellence in eye care that we offer.
Age >18
Constant Refractive error
Corneal thickness > 490 microns
Normal Corneal topography
Patients with a higher cylindrical refractive error in addition to the spherical power will benefit the most from Contoura Lasik surgery.
Contoura vision surgery has the following advantages over the existing LASIK platforms:
Better visual acuity: The post-operative refractive corrections on the Contoura are found to be better as compared to LASIK in terms of quality and quantity of vision. Some of the patients even experienced visual acuity better than 6/6.
Broader scope: In addition to correction of refractive error, Contoura can treat the corneal curvatural abnormalities.
Advanced technology: Contoura vision is the most advanced form of LASIK. The Contoura vision surgery maps 22,000 points on the cornea as compared to the conventional LASIK surgery which maps only 200 points on the cornea.
Fewer complications: The complication rate of Contoura LASIK is less as compared to the conventional LASIK surgery. Minimal damage to the tissue and relatively faster healing time make the post-operative recovery period quicker.
Most patients feel minimal or no pain during the procedure.
Immediately after the Contoura procedure, the first thing many patients notice is how clearly they can see the objects around them. During this initial period, they may also be sensitive to bright light and the vision may also be slightly blurry. This happens because the cornea is still healing, and once it heals, these issues may subside.
Over the months following the surgery the quality of the vision will improve gradually.
LASIK is considered as an elective and cosmetic procedure. Therefore, it may not be covered by private insurances. However, your insurance company executive can best answer.
Some amount of glare or visual difficulty in very bright light at night is experienced immediately post-surgery. However, gradually these symptoms will reduce as the eye heals.
Contoura LASIK refractive correction is permanent. However, ageing results in changes in the natural lens inside your eye while will eventually affect your vision. As above the age of 40 years, most people develop presbyopia, near reading glasses may be required.
