Ophthalmology & Optometry

Welcome to United Eye Centers. We are committed to offering the best options for corrective vision. Our physicians are recognized as leaders in the medical community by 5280 Magazine and other medical professionals in the Denver Metro area. With three offices to choose from, we offer a convenient and compassionate staff ready to serve our patients.


iLASIK combines the power of WaveScan optical scanning, the VISX CustomVue system and the InterLase blade-free approach to create an ultra-accurate incision. This advanced technology gives the surgeons at United Eye Centers unprecedented customization, so every patient receives the exact correction they need. Since iLASIK is so accurate, United Eye Centers can serve patients who were previously not considered candidates for laser vision correction.

Cataract Surgery

Cataracts affect almost everyone, sooner or later. The only treatment for a cataract is removal of the affected natural lens of the eye and implantation of a lens implant, or intraocular lens (IOL). This restores the eye's ability to have light pass unobstructed through to the retina. Over 14 million Cataract procedures are performed worldwide each year.
