Cataract surgery is one of the safest and most common procedures performed in the world. All surgery has risks associated with it and our staff will review the risks, benefits and alternatives during your consultation. The LensAR Laser is unique in that it uses a liquid interface between the surface of your eye and the laser device. This advanced interface creates a painless suctioning effect that immobilizes the eye so we can take precise measurements and create exact incisions. As a result of the suction, most patients will have a small, red ring in white portion of the eye. This redness will go away after a few days.
