About Us


IQ Laser Vision’s mission is to enhance the lives of our patients. At IQ Laser Vision, we know there’s a better way because we’ve personally helped over 150,000 patients to see the world through new eyes since our Orange County and Los Angeles County facilities first opened in 1999. Utilizing the state-of-the-art technological advances, the expert doctors at IQ Laser Vision can make it possible for you to achieve your clearest, sharpest vision, safely, quickly, and easily. Once you recognize your right to a lifetime of clear vision and the countless benefits it offers, IQ Laser Vision can do the rest.

Over the last two decades, over 20 million people world-wide have turned to LASIK in order to decrease their dependency from glasses or contacts by treating their nearsightedness, farsightedness, astigmatism, and even presbyopia. Patients who have undergone laser eye surgery will commonly share that their LASIK procedure was a life-changing experience for them. With the incredible technological advances in LASIK vision correction, LASIK is safer than wearing contact lenses.
