Why Fontana Patients Choose Eye MDs of Inland

Fontana patients most often come to us for cataract surgery second opinions and for diabetic eye care. If you’d like to know whether a premium lens implant could free you from glasses — or you simply want a surgeon who takes the time to explain your options in English or Spanish — the 20 minute drive earns you two UCLA-trained specialists in one office.

Glaucoma deserves its own specialist: diagnosis and treatment are provided through Inland Glaucoma Center, our dedicated glaucoma division in the same Upland building, led by a UCLA fellowship-trained glaucoma specialist.
