Approved by the FDA, Contoura VisionTM, or the Topography guided laser vision correction is the the most near perfect vision correction that you can get in Mumbai. It is not limited to just the spectacles prescription, on the whole, Contoura VisionTM treats even the smallest of imperfections that are unique to each patient’s cornea.
This ability of Contoura VisionTM, to rectify both, the eye glass prescription and the corneal irregularities, makes the patient’s eye, focus better and also improves their vision.
Ojas eye hospital in Mumbai, are the pioneers of bringing this advanced technology in Mumbai. Our highly experienced LASIK surgeons are equipped with, this most advanced excimer laser system.
This laser system, measures the patients cornea, and communicates it to the software, so that the treatment can be carried out accordingly.
On the day of the treatment, or the day before it, pictures of the patients eye is taken by the corneal topographer called the Vario or Topolyzer.
The shape characteristics of the patient’s eye is also measured
The Vario or Topolyzer then sends 22000 data ...
... points to the surgical planning computer
A highly customized treatment plan, based on the unique shape of the patient’s cornea is created.
Following which, the treatment plan is sent to the Wavelight EX500 excimer laser system which then performs under the guidance of the best LASIK surgeons in Mumbai at Ojas eye hospital.

The difference between Contoura Vision™ and other Custom Lasik treatments.
Europe, Canada, United States etc. have been relying on Contoura Vision™ for more than a decade.
Contoura Vision™ is a unique topography guided Lasik procedure which maps the eye and guides the treatment.
It measures every sub-microscopic peaks and valleys of the cornea with the utmost precision, through it’s topography instrument called Vario Topolyzer.
The Wavefront-guided Lasik, also gives good results, as it measures around 200 points of the cornea’s curvature. While the Contoura Vision™ measures 22000 points, which allows the software to create a highly customized treatment, which is then programmed into the laser, and the cornea is treated automatically.
The laser brings the cornea’s shape, back to normal, so all the light rays passing through it reach the retina, at the back of the eye uniformly, thus producing an extremely clear and sharp vision.
Contoura Vision™ is highly customized, because the topography measurements are so accurate, that it makes it impossible for any two patients to have the same treatment.
Wave-front Lasik measures all parts of the eye along the visual pathway while Topography measurements include only the cornea, which hosts most imperfections of the eyes. The lens of the eye may also contribute to poor vision, but that may change over a certain time period, which may then work against the changes made to the cornea by the Lasik.
Contoura Vision™-Topography guided Laser Vision Correction, rectifies the cornea’s surface with such precision, that patient’s may experience a better quality vision than before.
