Keratoconus & Specialty Lenses in the Central Valley

Book Your Appointment

What is Keratoconus?

The cornea is the outermost part of the eye, shaped like a transparent dome. The cornea is part of the refractive system responsible for focusing light into the eye. Healthy corneas are rounded half-spheres that allow light to focus onto the retina, creating a clear image. Eyes with keratoconus have corneas that are irregular and bulge out like a cone, making vision blurry or distorted.

Keratoconus is suspected to be genetic in many cases but has also been associated with eye allergies and excessive eye rubbing.

Keratoconus usually affects both eyes, but often asymmetrically. Symptoms may vary in each eye and may change over time. Some signs of keratoconus include:

  • Blurred, distorted or double vision
  • Straight lines appearing bent or wavy
  • Increased sensitivity to light
  • Discomfort, redness, or swelling of the eyes

As keratoconus progresses, vision will usually worsen. Nearsightedness or astigmatism may increase and cannot be properly corrected with glasses, and wearing traditional soft contact lenses may become uncomfortable or painful.

Symptoms of keratoconus typically worsen gradually over years. However, some cases progress rapidly. It’s essential to have your health and vision examined regularly to pinpoint early signs of eye diseases.

Specialty Lenses

With certain eye conditions like keratoconus, traditional contact lenses are uncomfortable and may even be painful to wear. They may also not offer clear vision. We offer a variety of specialty lenses that work for hard-to-fit eyes, so clear vision is accessible for the broadest range of patients.

Typical contact lenses are spherical, but these lenses do not account for aberrations. Colored contact lenses provide precise light guidance and optimal vision correction.

Toric contact lenses have different focusing powers along the vertical and horizontal axis and are designed to correct astigmatism.

Rigid gas permeable lenses are made of a firm plastic that allows oxygen to pass through. They retain their shape on the eye, allowing for crisp vision that may be preferable for some eye conditions such as astigmatism.

Multifocal contact lenses have 2 or more powers in each lens to correct different focal points. Different designs include:

  • Concentric, where the central portion of the lens is for near vision and the surrounding area is for distance, or vice versa.
  • Aspheric, constructed like progressive multifocal lenses, where the central part is for near vision, and the lens power gradually changes as you move outwards.

Multifocal contact lenses are typically used to correct presbyopia by providing both near and distance vision correction.

Scleral lenses are larger than typical contact lenses, designed to vault over the cornea and rest on the sclera. These lenses create a smooth ocular surface for corneal irregularities such as keratoconus. Additionally, they provide a reservoir between the cornea and back of the lens for fluid to continually bathe the eye.

Hybrid contact lenses are a combination of rigid gas permeable and soft lenses. The central portion of the lens is a rigid material, with a surrounding soft lens “skirt”. These lenses provide the crisp vision of rigid lenses with the comfort of soft contacts.
