Keratoconus Specialist and Scleral Lenses in Rogers, AR
Keratoconus can make clear, stable vision difficult to achieve with ordinary glasses or soft contact lenses. As the cornea becomes thinner and develops an irregular cone-like shape, patients may experience blur, glare, light sensitivity, ghost images, or frequent prescription changes.
Parenti-Morris Eyecare provides keratoconus evaluations and customized scleral lenses in Rogers. If you are searching for a keratoconus specialist near me, our team can evaluate your corneal shape, vision, and contact lens needs to determine whether specialty lenses may help.
Scleral lenses require more precise measurements and follow-up than standard contacts. Learn more about our approach to contact lens examinations and fittings.
What Is Keratoconus?
Keratoconus is a progressive corneal condition. The cornea is the clear, curved surface at the front of the eye that helps focus light. A healthy cornea usually has a smooth, rounded shape.
With keratoconus, the cornea gradually becomes thinner and bulges forward into an irregular cone-like shape. This irregularity prevents light from focusing evenly on the retina, which can cause distorted or fluctuating vision.
Keratoconus often begins during the teenage years or early adulthood, although its timing and rate of change vary. It may affect one eye more than the other.
What Are the Symptoms of Keratoconus?
Keratoconus symptoms can change as the corneal shape becomes more irregular. Signs may include:
- Blurred or distorted vision
- Ghost images or double vision in one eye
- Increased sensitivity to light
- Glare or halos around lights
- Difficulty seeing while driving at night
- Frequent changes in an eyeglass prescription
- Increasing astigmatism or nearsightedness
- Difficulty achieving clear vision with glasses
- Contact lenses that no longer fit comfortably
- Eye strain or headaches associated with visual effort
Some of these symptoms can occur with other eye conditions. A detailed eye examination is needed to identify whether keratoconus or another corneal problem is responsible.
What Causes Keratoconus?
The exact cause of keratoconus is not fully understood. Genetic, environmental, and structural factors may all play a role.
Factors associated with a higher likelihood of keratoconus include:
- A family history of keratoconus
- Frequent or forceful eye rubbing
- Chronic eye allergies
- Certain connective tissue or genetic conditions
- Changes in the strength and structure of the cornea
Having one of these factors does not mean that someone will develop keratoconus. Likewise, some people diagnosed with the condition have no known family history or obvious risk factors.
If allergies cause persistent itching, speak with your eye doctor about safer ways to manage symptoms instead of rubbing your eyes.
What Is Keratoconus?
Keratoconus may initially resemble ordinary nearsightedness or astigmatism. A standard prescription check may not provide enough information to explain why vision remains distorted or changes frequently.
A keratoconus evaluation may include:
- A review of your symptoms and prescription history
- Measurement of your visual acuity
- Refraction to evaluate how lenses affect your vision
- Slit-lamp examination of the cornea
- Assessment of corneal shape and curvature
- Measurement of the cornea for specialty contact lenses
- Evaluation of how each eye is affected
Corneal mapping or other specialized measurements may be used to identify irregular areas and guide lens design. These findings help your doctor determine whether glasses, conventional contacts, or specialty lenses are likely to provide the most useful vision.
A comprehensive eye examination also allows your doctor to assess the health of the surrounding eye structures.
Why Is Early Keratoconus Care Important?
Keratoconus can change over time. Regular monitoring helps your eye doctor document changes in the corneal shape, prescription, and quality of vision.
An updated evaluation is especially important when:
- Vision changes more quickly than expected
- A glasses prescription no longer provides clear vision
- Astigmatism increases repeatedly
- One eye becomes noticeably blurrier than the other
- Glare or night-driving difficulty becomes more pronounced
- Existing contact lenses become uncomfortable or unstable
Specialty lenses improve vision while they are worn, but they do not permanently reshape the cornea or stop keratoconus from changing. Continued monitoring remains important even when scleral lenses provide excellent vision.
What Are Scleral Lenses?
Scleral lenses are large-diameter, gas-permeable contact lenses. Unlike standard contacts that sit directly on the cornea, scleral lenses vault over the corneal surface and rest on the sclera, which is the white part of the eye.
Before insertion, the lens is filled with preservative-free saline. This creates a fluid reservoir between the back of the lens and the cornea.
The lens design creates a smooth optical surface over the irregular cornea. This may reduce visual distortion and provide clearer, more stable vision than glasses or conventional soft lenses can achieve for some patients.
How Can Scleral Lenses Help With Keratoconus?
Keratoconus causes irregular astigmatism that may be difficult to correct with ordinary glasses. Because a scleral lens vaults over the cornea instead of matching every irregularity, it can create a more regular refractive surface.
Potential benefits of scleral lenses for keratoconus include:
- Clearer and more stable vision
- Reduced ghosting and visual distortion
- Improved lens stability
- Less interaction with the sensitive corneal surface
- A customized fit for an irregular cornea
- A fluid reservoir over the cornea
- Improved comfort compared with some smaller rigid lenses
Results depend on the degree of corneal irregularity, eye health, prescription, and lens fit. Scleral lenses do not cure keratoconus, but they may provide meaningful visual improvement while worn.
Who Else May Benefit From Scleral Lenses?
Although scleral lenses are commonly associated with keratoconus, they may be considered for other irregular corneal or ocular surface conditions.
Depending on the examination findings, scleral lenses may be used for patients with:
- Other forms of irregular astigmatism
- Corneal scarring
- Irregular corneas following an injury or procedure
- Certain corneal disorders
- Severe ocular surface disease
- Persistent intolerance to conventional contact lenses
The fluid reservoir beneath a scleral lens may also support the corneal surface in selected patients with severe dryness. Patients whose primary concern is dryness can learn more about dry eye treatment in Rogers.
What to Expect During a Scleral Lens Fitting
Scleral lenses are individually selected and adjusted. The process typically requires more than one visit because the lens must provide clear vision while maintaining an appropriate relationship with the cornea, sclera, and tear reservoir.
1. Eye and Corneal Evaluation
Your doctor evaluates your vision, corneal shape, eye health, tear film, and previous experience with glasses or contact lenses. Measurements help guide the initial diagnostic lens selection.
2. Diagnostic Lens Assessment
A diagnostic scleral lens is placed on the eye and allowed time to settle. Your doctor evaluates its position, movement, corneal clearance, edge alignment, and the fluid reservoir beneath the lens.
3. Prescription and Design Refinement
Your vision is tested through the diagnostic lens. The prescription and physical lens design may be adjusted according to how the lens fits and how clearly you see.
4. Lens Application and Removal Training
Once your lenses are ready, our team teaches you how to apply, remove, fill, clean, and store them. Scleral lenses require a consistent routine and specific products.
5. Follow-Up Visits
Follow-up appointments allow your doctor to evaluate vision, comfort, lens settling, and corneal health after you have worn the lenses in daily life. Adjustments may be needed before the final fit is achieved.
How Long Does It Take to Adjust to Scleral Lenses?
Every patient’s experience is different. Some people notice improved vision immediately, while handling the lenses confidently may take additional practice.
Scleral lenses are larger than ordinary contacts and must be filled with preservative-free saline before application. Air bubbles beneath the lens can affect comfort and vision, so learning the correct technique is an important part of the fitting process.
Your care team will explain:
- How to recognize whether the lens is centered correctly
- How to check for bubbles
- Which products to use for filling and disinfection
- How long to wear the lenses
- When to remove them
- Which symptoms require a call to the office
Follow the wearing schedule prescribed by your doctor rather than extending wear time on your own.
How to Care for Scleral Lenses
Proper care protects your eyes and helps maintain lens performance.
- Wash and thoroughly dry your hands before handling lenses.
- Use only the filling and cleaning products recommended by your doctor.
- Fill lenses with the prescribed preservative-free saline.
- Never use tap water or saliva on your lenses.
- Clean and disinfect lenses after removal.
- Use fresh solution rather than topping off old solution.
- Keep your lens case clean and replace it as directed.
- Do not sleep, shower, swim, or use a hot tub while wearing lenses unless your doctor has provided specific instructions.
- Attend all recommended follow-up visits.
Remove the lens and contact your eye doctor if you experience significant pain, increasing redness, discharge, light sensitivity, or a sudden change in vision.
