Scleral Lenses vs. Standard Contacts for Keratoconus & Astigmatism: A Garden Grove Patient Guide

For many people, standard soft contact lenses provide clear, comfortable vision. However, patients with keratoconus, irregular corneas, or certain types of astigmatism may need a more customized solution. At OC Vision Center in Garden Grove, we offer specialty contact lens options, including scleral lenses, to help patients who may not achieve the vision they want with traditional contacts.
 

Why Standard Contacts May Not Work for Keratoconus

Keratoconus causes the cornea to become thinner and develop a cone-like shape. Because the corneal surface is irregular, standard soft contact lenses may not sit evenly on the eye. This can result in blurred, distorted, or fluctuating vision.
 

Some patients with mild astigmatism do very well with traditional soft toric contacts. However, more complex or irregular astigmatism can make it harder for standard lenses to provide consistent correction.
 

Signs that standard contacts may not be meeting your needs include:

• Vision that remains blurry even with an updated prescription

• Frequent lens movement or shifting

• Fluctuating clarity throughout the day

• Difficulty seeing clearly at night

• Discomfort or limited contact lens wear time
   

How Scleral Lenses Are Different

Scleral lenses are larger-diameter rigid lenses that vault over the cornea and rest on the white portion of the eye, called the sclera. Instead of following the irregular shape of the cornea, the lens creates a smooth optical surface in front of it.
 

The space between the scleral lens and the cornea is filled with sterile saline. This design can provide more stable vision while also helping keep the corneal surface hydrated during wear.
 

For patients with keratoconus in Garden Grove, scleral lenses may offer clearer and more consistent vision than standard contacts, particularly when the corneal shape is significantly irregular.
 

What About Astigmatism?

Whether scleral lenses are appropriate for astigmatism depends on the type and severity of the condition. Regular astigmatism can often be corrected successfully with soft toric lenses. Irregular astigmatism, especially when associated with keratoconus or another corneal condition, may benefit from a more customized lens design.
 

That is why a detailed contact lens evaluation is important. We assess your prescription, corneal shape, eye health, comfort needs, and previous contact lens experience before recommending an option.
 

Choosing the Right Contact Lens in Garden Grove

There is no single contact lens that is right for everyone. Standard soft contacts may remain an excellent option for patients with regular prescriptions and healthy corneas. Scleral lenses are designed for more complex situations where standard lenses cannot provide satisfactory clarity, stability, or comfort.
 

At OC Vision Center, our specialty contact lens services are tailored to each patient's individual vision needs.
