Jon Siems, MDJon L. Siems, MD (View reviews: Patient Testimonials, Yelp!,  Verified Reviews®)

Dr. Siems is one of the most recognizable names in the field of refractive surgery. As his credentials will show, he has been a pioneer in refractive surgery serving as a principal investigator for 3 large FDA trials. He was selected as one of the first surgeons in the United States to investigate the surgical correction of presbyopia. He is a contributing co-author of a seminal book on the subject.

Dr. Siems is also one of the most experienced refractive surgeons in the United States and is certified by the American Board of Ophthalmology. He has performed many thousands of Lasik and lens-based (cataracts) surgeries. Dr. Siems was one of the first 5 doctors in the United States to use the IntraLase onsite. He is a fellow of the American Academy of Ophthalmology as well as a member of the American Society of Cataract and Refractive Surgery.

Dr. Siems was the first surgeon in Nevada to perform the bladeless lasik procedure.

Dr. Siems previously served as Director of the UCLA Los Angeles Inland Laser Center, the LCA San Bernardino Laser Center, the Ontario Laser Center, and the Laser Vision Institute of Las Vegas. These experiences have allowed Dr. Siems to open what some in the field of refractive surgery claim is the most advanced Lasik and refractive surgery center in the U.S.

Board certified and fellowship trained Dr. Siems, specializes in ADVANCED VISION CORRECTION procedures and often treats the more complicated cases other doctors are unable to treat.
