Welcome to CKOD

Serving Las Vegas & Henderson families since 1998

Welcome to Cynthia Kiernan, O.D. & Associates

As our patient, you know you are in good hands with Cynthia Kiernan, OD & Associates.  Las Vegas and Henderson residents have trusted our office with their eyes since 1999, relying on us for comprehensive eye exams, diagnosis and treatment of eye diseases, glasses prescriptions, and contact lens fittings.  We serve our community by providing evaluations for a variety of common eye conditions including: allergies, pink eye, dry eyes, foreign body removal, cataract consultation, glaucoma screening, and diabetic eye examinations.

We pledge to provide a comfortable, friendly atmosphere with no sales pressure. Our practice proudly offers expert professional services only, and does not profit from the sales of eyewear or contact lenses. We are happy to give you a copy of your prescription to take with you at the conclusion of your exam. For the ultimate convenience, the Walmart Vision Center is located next to our practice. Showcasing a wide selection of eyewear products at various price points, the Walmart Vision Center offers top brands at low prices and the convenience of in-stock contact lenses.
