Contact Lenses

While in training Dr. Todd received the outstanding student contact lens research award and has continued his strong interest in both standard and specialty contact lenses. There have been wonderful changes in soft lens materials over the last few years that make contact lenses even better options than in the past. New materials in rigid contact lenses have opened up opportunities for patients who may not have been successful in the past. We routinely fit lenses for more difficult problems such as high amounts of astigmatism, bifocals, and dry eye patients. Patients with kerataconus and previous eye surgery are also often candidates for contact lenses.

Lens Materials

There are a multitude of materials used for soft and rigid contact lenses. Each has properties that make it desirable for various circumstances. Your eye doctor will choose a lens appropriate for your needs and eyes.

Disposable Contact Lenses

Lenses designed to be disposed of regularly. Typically the term refers to lenses intended to discard daily, weekly, or every 2 weeks. These lenses may be either daily wear or extended wear.

Daily Disposable Contact Lenses

Soft lenses designed to be disposed after every use. Usually dispensed in packs of 30 or 90 lenses. Stay very clean and are never stored in disinfecting solution.

Daily Wear Soft Contact Lenses

Lenses not suitable for wearing while sleeping. These lenses are usually very durable and resistant to deposits. However usually allow relatively low amounts of oxygen through to the eye.

Extended Wear Soft Contact Lenses

Lenses that are designed to allow enough oxygen to potentially allow safe lens wear overnight. This doesn’t ensure that extended wear will be safe for every patient. You must check with your eye doctor to determine if this is appropriate for you. Many doctors prescribe extended wear lenses for daily wear use.

Rigid Contact Lenses

Often called “hard lenses”, modern rigid lenses are rigid gas permeable lenses. At times in the past some people have called these lenses “semi-soft” lenses because they allowed oxygen to pass through the lens material like a soft lens did. We have always felt this was misleading. These lenses are just as rigid as a “hard” lens. However these lenses are much healthier for your eyes than the older “hard” lenses.

Soft Contact Lenses

These lenses are truly soft, very much like a sponge. They absorb water as well as other contaminants from water, air, patient’s fingers, or from other chemicals coming in contact with the lens. They are generally very comfortable to the eye.
