When Regular Contacts Do Not Work: Lens Options for Keratoconus

Q: What makes keratoconus different from regular astigmatism or myopia?

Keratoconus causes the cornea to thin and become irregular, unlike typical astigmatism or myopia. This irregularity makes standard vision correction options less effective.

Q: How do specialty lenses improve vision with keratoconus?

Specialty lenses create a new, smooth optical surface that masks the corneal irregularity, sharply focusing light onto the retina. This design corrects distortions that regular contacts cannot address.

Q: Can specialty lenses delay or prevent corneal transplant?

Yes, properly fitted specialty contact lenses can maintain functional vision and comfort for long periods, often postponing or even preventing the need for a corneal transplant.

Q: Is the fitting process more complicated than for regular contacts?

Yes, the fitting process for keratoconus involves detailed corneal mapping, trial fittings, and ongoing follow-up to ensure optimal vision and comfort.

Q: What if I also have dry eye with keratoconus?

Specialty lenses like scleral lenses can help by maintaining a fluid reservoir over the eye, which alleviates dry eye symptoms while providing vision correction.

Q: How do I know if I need a more advanced lens?

If your current vision correction no longer provides clear vision or comfort, or if your corneal shape is worsening, it is time to consider a specialty lens evaluation.

Q: Do you fit hard-to-fit lenses at Lake Forest Family Optometric Eyecare?

Yes, our clinic has expertise in fitting hard-to-fit cases, including those involving keratoconus and surgically repaired corneas.

When Regular Contacts Do Not Work: Lens Options for Keratoconus

Keratoconus brings unique challenges to vision correction, especially when traditional soft contact lenses begin to falter. For individuals with keratoconus who find that regular contacts no longer provide clear or comfortable vision, several specialized lens options exist. These advanced designs are tailored to address the irregular shape of the cornea caused by keratoconus, restore sharper focus, and maximize day-to-day comfort. At Lake Forest Family Optometric Eyecare, we specialize in diagnosing keratoconus and expertly guiding patients through the complex landscape of specialty contact lenses.

Keratoconus alters the smooth dome of the cornea, making standard contact lenses ineffective for many as the condition progresses. When regular contacts stop working, consultation with optometrists experienced in complex lens fittings becomes crucial. Below, we outline the core specialty lens solutions, describe the fitting process, and provide guidance on how patients in Lake Forest and throughout Orange County can find their best options for keratoconus vision correction.

What Is Keratoconus and Why Do Regular Contacts Eventually Fail?

Keratoconus is a progressive eye condition in which the cornea thins and bulges into an irregular, cone-like shape. This distortion interferes with how light enters the eye, leading to symptoms such as blurred vision, ghosting, halos, light sensitivity, and regular prescription changes. Regular soft contacts generally conform to the corneal shape without correcting the irregular surface, so they often become ineffective as keratoconus progresses.

Common Reasons to Consider Specialty Contact Lenses

Blurry vision or ghosting, even with glasses or soft contacts
Regular contacts feel uncomfortable, slip, or move excessively
Increased glare, halos, and double vision
Changes in prescription frequency
Difficulty with daily tasks such as reading, working, or night driving

If any of these occur, it’s a strong indication that advanced lens options and custom fitting may be necessary. At Lake Forest Family Optometric Eyecare, we are highly experienced in evaluating and fitting lenses for keratoconus at every stage.

Specialty Lens Options for Keratoconus

The right contact lens for keratoconus depends on corneal shape, degree of irregularity, previous lens success, and individual comfort. The most commonly used options include:

1. Rigid Gas Permeable (RGP) Lenses

RGP lenses are frequently the first step beyond regular lenses.
They provide a new, smooth optical surface above the misshapen cornea, which delivers sharper vision for many keratoconus patients.
Custom-made to match the topography of the individual cornea.
Ideal for mild to moderate keratoconus, but some may find them less comfortable for extended wear.

2. Custom Soft Contact Lenses for Keratoconus

Thicker or larger soft lenses designed specifically for mild keratoconus or those unable to tolerate RGPs.
May offer improved comfort but usually provide less visual sharpness than rigid designs.
Potentially a good option at early stages or for part-time wear.

3. Piggyback Lens Systems

A soft contact lens is worn beneath an RGP lens, providing a comfort "cushion" against irritation.
Used for those who benefit from rigid optics but cannot wear RGPs alone comfortably.
Requires careful fitting to ensure the health of the cornea and adequate oxygen supply.

4. Hybrid Contact Lenses

Feature a central RGP zone for crisp vision and a soft, flexible outer skirt for added comfort and stability.
Designed to balance sharp vision with the comfort of a soft lens.
Often considered for those who want the benefits of both lens types.

5. Scleral and Semi-Scleral Lenses

Large-diameter rigid lenses that vault completely over the cornea and rest on the white part of the eye (sclera).
Especially valuable for moderate to advanced keratoconus, highly irregular corneas, or patients who cannot tolerate corneal RGPs or hybrids.
Filled with preservative-free saline before insertion, maintaining a fluid reservoir that can also help with dry eye symptoms.

6. PROSE Devices

Ultra-specialized, custom scleral prosthetic lenses used when all other options fail.
Reserved for advanced, medically complex keratoconus cases prior to considering corneal transplant.

How Do Optometrists Choose the Right Keratoconus Lens?

Contact lens selection is individualized based on several factors:

Corneal Shape & Stage: The more advanced the keratoconus, the more likely scleral or hybrid lenses will be needed, while early cases may succeed with custom soft or RGP lenses.
Comfort and Wearing Time: A lens only works if it can be comfortably worn throughout the day. Adjustments may be needed over time.
Visual Outcomes: The goal is to maximize both clarity and quality of vision while protecting corneal health.
Dryness or Other Ocular Surface Issues: Lenses like sclerals can offer relief if dry eye coexists with keratoconus.

At Lake Forest Family Optometric Eyecare, our optometrists perform detailed corneal measurements and assessments to guide every patient toward the optimum solution. Specialty lens fitting is a step-by-step, iterative process—often requiring multiple trials for precise vision and comfort.
