Cataract Surgery & Eye Care
for Fontana Patients
Fontana patients drive about 20 minutes west on the 10 or 210 to reach Eye MDs of Inland in Upland — a trip many make for one reason: their cataract surgery is performed personally by UCLA-trained, board-certified surgeons who offer the complete range of premium lens implants. Se habla español.

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.
