Keratoconus, Astigmatism & Scleral Lenses: Understanding Your Vision Options in Hayward, CA

Vision problems can range from mild blurriness to severe distortion. Two common corneal conditions—astigmatism and keratoconus—affect vision differently, and the right treatment depends on the severity and progression of the condition. At our Hayward, CA eye care clinic, we provide personalized solutions to help you see clearly and comfortably.

What is Astigmatism?

Astigmatism occurs when the cornea or lens has an irregular shape, causing light to focus unevenly on the retina. This results in blurred or distorted vision at all distances.

Symptoms:

• Blurry or distorted vision

• Eye strain or fatigue

• Headaches after reading or screen use

Treatment Options:

• Glasses with astigmatism correction

• Soft contact lenses or rigid gas permeable (RGP) lenses

Astigmatism is usually stable over time and can often be corrected with conventional glasses or contacts.

What is Keratoconus?

Keratoconus is a progressive eye condition in which the cornea thins and bulges into a cone shape, distorting vision. Unlike astigmatism, keratoconus worsens over time and can significantly affect daily activities.

Symptoms:

• Blurred or distorted vision

• Halos or glare, especially at night

• Difficulty seeing fine details

Keratoconus often develops in adolescence or early adulthood and may affect one or both eyes.

Scleral Lenses – A Solution for Keratoconus and Irregular Astigmatism

Scleral lenses are large-diameter rigid lenses that vault over the cornea and rest on the sclera, creating a smooth optical surface. They are particularly beneficial for:

• Patients with keratoconus

• Individuals with irregular corneas or severe astigmatism

• Those who cannot tolerate conventional contact lenses

Benefits of Scleral Lenses:

• Sharp, stable vision

• Comfortable even on irregular corneas

• Protects and hydrates the eye

Scleral lenses create a fluid-filled space between the lens and the cornea, correcting vision and cushioning the sensitive corneal surface.

Choosing the Right Vision Option

• Mild Astigmatism: Glasses or soft contact lenses

• Progressive Astigmatism or Keratoconus: Scleral contact lenses or sometimes rigid gas permeable contact lenses

• Consult an Eye Specialist: Personalized assessment ensures the best vision solution for your eyes
