Since time immemorial, eye surgeons have struggled and strived to give patients the best visual outcome after cataract surgery. Incisions got smaller, better lens implants were developed and outcomes improved. But the problem of incision induced astigmatism continued to be an issue. No matter how small the incision, upon healing it produces a pull on the cornea, distorting its natural curvature, thus impacting vision after surgery. This often resulted in the necessity of astigmatic spectacles.
Various calculations were made to plan incisions so that this impact could be reduced but reliable results could not be attained.
Finally, technology came to the rescue! With Verion assisted precision cataract surgery, patients’ cornea and sclera are mapped preoperatively and Verion calculates where exactly each cut should be made so that minimal astigmatism is produced post operatively. Not only that, during surgery Verion is synced with the operating microscope so that it superimposes these customized calculations on the image seen by the surgeon. This superimposed image is matched and moves along with the minute movements of the eye during surgery. Site of optimum incisions are displayed for the surgeon to use as guides.
Other benefits of Verion are that it guides the surgeon as to where to center his/her circular opening on the anterior (front) capsule of the lens and where to center the IOL so that best vision is obtained.
Particularly for patients with astigmatism, Verion guides the surgeon as to where to make the incision through which the IOL is to be inserted so that pre-existing astigmatism can also be eliminated.
The result is the best possible visual result with minimal astigmatism in all cases.
