Scleral Lenses for Keratoconus & Astigmatism in Chula Vista: A Custom Fit Guide

When keratoconus or astigmatism makes clear, comfortable vision difficult to achieve with standard contacts, a more customized solution may be needed. At Eastlake Vision, we provide specialty contact lens fittings in Chula Vista to help patients with complex corneal shapes find better visual clarity and comfort. Scleral lenses are one option that can be especially helpful when traditional lenses do not provide the stability or correction you need.

How Scleral Lenses Work

Unlike standard contact lenses that sit directly on the cornea, scleral lenses are larger and rest on the white portion of the eye, called the sclera. The lens vaults over the cornea, creating a smooth optical surface that can compensate for irregularities in its shape.

A preservative-free saline solution fills the space between the lens and the cornea. This design can provide consistent vision while reducing direct contact with a sensitive or irregular corneal surface.

Why Scleral Lenses Can Help With Keratoconus

Keratoconus causes the cornea to become thinner and gradually develop a cone-like shape. As the corneal surface becomes irregular, glasses and traditional soft contacts may no longer provide adequate vision correction.

Scleral lenses for keratoconus create a new, smooth refractive surface over the irregular cornea. For many patients, this can improve visual quality and provide a more stable fit throughout the day.

Patients may benefit from scleral lenses if they experience:

•          Blurred or distorted vision from keratoconus

•          Irregular astigmatism

•          Difficulty wearing standard soft or rigid contact lenses

•          Fluctuating vision with conventional contacts

•          Discomfort related to an irregular corneal surface

Scleral Lenses for Astigmatism

Astigmatism occurs when the cornea or lens of the eye has an uneven curvature, preventing light from focusing evenly. While many cases can be corrected with glasses or toric contact lenses, more complex or irregular astigmatism may require specialty contacts.

Because scleral lenses maintain their shape over the cornea, they can create a more uniform optical surface. This can make them an effective option for certain Chula Vista patients whose astigmatism is difficult to correct with conventional lenses.

Why a Custom Scleral Lens Fit Matters

Scleral lenses are not one-size-fits-all. Their effectiveness depends on careful measurements and a personalized fitting process. During your specialty contact lens evaluation, we assess your corneal shape, prescription, eye health, and visual needs to determine whether scleral lenses are appropriate for you.

A precise fit helps ensure the lens clears the cornea properly, stays stable on the eye, and provides comfortable vision. Follow-up appointments also allow us to evaluate the fit and make adjustments when necessary.

At Eastlake Vision, we take the time to understand your vision concerns and find a contact lens solution suited to your individual eyes. Our goal is to help patients with keratoconus, astigmatism, and other challenging corneal conditions achieve clearer, more dependable vision.
