Blurry vision. Cataracts, a cloudiness in the natural lens of the eye, can cause different types of blurry vision syimptoms such as glare, fuzziness, haze, loss of clarity. Removing them is done by ultrasound, and is called phaco emulsification. A newer laser modality - the femtosecond laser can assist in some parts of the surgery. Preliminary studies are ongoing as to efficacy and safety of this new modality.
