Contoura Vision FemtoLASIK

What is Contoura Vision?

Contoura Vision TopoGuided LASIK is a new technology designed to enhance the effects of LASIK. It corrects the vision based on the corneal topography (corneal curvature maps) as against the correction of vision in a standard LASIK surgery which is only based on glasses or contact lens prescription.

Contoura Vision TopoGuided LASIK involves the use of a separate diagnostic device called topolyser which provides measurement of 22,000 points on the cornea capturing the imperfections in both the curvature and the optics of the cornea. These topographic measurements are then combined with the patient’s eyeglass prescription and a customized treatment profile is created and programmed into the state of the art laser. The final laser ablation is performed by the WaveLight EX 500 Excimer laser system. Thus this technology works to optimize the corneal surface during LASIK procedure.  

What makes Contoura Vision so unique?

The Topolyser has unparalleled diagnostic capabilities to record even the minutest imperfections in the curvature of the cornea. It provides an incredible measurement of 22,000 points as compared t...

How does it help?

Since Contoura Vision combines refractive prescription with corneal topography maps it provides improved quality of vision to the patients. Food and Drug Administration (FDA) results reveal that the patients who opted for this technology had a significant improvement and were able to see even more clearly without corrective eyewear. As per the clinical trials statistics, almost 90% of patients post-operatively saw as well or better without glasses than they ever did with glasses.

What are the benefits and risks of this technology?

Contoura Vision technology is a boon for patients suffering from different refractive errors. It has many benefits, but a few risks too.

  • Reduced or absent dependence on glasses
  • Decrease in difficulty during night driving
  • Lesser sensitivity towards light, less glare
  • Better quality of vision

  • Dry eyes is common in the postoperative period that improves in a few months with lubricating eye drops
  • Under or overcorrection is extremely rare with the current generation of machines and available technology. However they can be treated by an enhancement procedure done at le
