Blurred or Distorted Vision
Vision may appear irregular or distorted because the cornea no longer focuses light evenly.
CORNEAL HEALTH
Understanding
keratoconus.
Keratoconus changes the shape of the cornea and can significantly affect vision. Early detection and appropriate management may help preserve visual function.
All ServicesABOUT THE CONDITION
What is keratoconus?
Keratoconus is a progressive eye condition in which the cornea becomes thinner and develops an irregular, cone-like shape. This changes how light enters the eye and can cause distorted or blurred vision.
Keratoconus often first becomes noticeable during adolescence or early adulthood. Its progression varies between individuals, making early detection and monitoring especially important.
RECOGNIZING SYMPTOMS
Signs of keratoconus.
Increasing Astigmatism
Frequent changes in eyeglass prescriptions or increasing irregular astigmatism may suggest changes in corneal shape.
Glare & Light Sensitivity
Patients may notice halos, glare, sensitivity to bright light, or difficulty seeing at night.
Difficulty With Standard Glasses
As corneal irregularity increases, ordinary glasses may no longer provide satisfactory visual clarity.
DIAGNOSIS & MANAGEMENT
How keratoconus is evaluated.
A comprehensive eye examination may identify signs of keratoconus. Corneal topography or tomography can map the corneal shape and help detect irregularities and monitor progression.
Corneal Imaging
Detailed measurements help evaluate corneal curvature, thickness, and changes over time.
Specialty Contact Lenses
Rigid gas-permeable and scleral contact lenses can improve vision by providing a more regular optical surface.
Corneal Cross-Linking
Cross-linking uses riboflavin and controlled ultraviolet-A light to strengthen corneal tissue and reduce the likelihood of further progression.
Additional Surgical Options
In advanced cases, other procedures, including corneal transplantation, may be considered by a corneal specialist.
iLINK CORNEAL CROSS-LINKING
What happens during cross-linking?
The FDA-approved iLink corneal cross-linking approach combines riboflavin eye drops with controlled ultraviolet-A light to strengthen corneal collagen. Its primary purpose is to slow or halt progression of eligible keratoconus, not to eliminate the need for glasses.
01 / PREPARATION
Prepare the cornea
Numbing drops are applied. In the epithelium-off procedure, the outer corneal layer is gently removed.
02 / TREATMENT
Apply riboflavin and UV light
Riboflavin drops are administered according to the treatment protocol, followed by controlled UV-A exposure.
03 / HEALING
Support recovery
A protective bandage contact lens and prescribed medications may be used while the corneal surface heals.
RECOVERY & AFTERCARE
What to expect after treatment.
Discomfort, tearing, light sensitivity, and temporarily blurred vision can occur following epithelium-off cross-linking. Healing time varies, and visual stabilization may take several months.
Your surgeon will provide specific instructions about eye drops, protective lenses, contact lens wear, activity restrictions, and follow-up appointments.
COMMON QUESTIONS
Keratoconus FAQs.
Can keratoconus cause permanent vision problems?
Progressive corneal irregularity can significantly reduce vision. Advanced disease may cause scarring and sometimes requires surgical intervention.
Does cross-linking cure keratoconus?
No. Its main goal is to slow or stop progression. Patients may still need glasses or specialty contact lenses.
Is cross-linking painful?
Numbing drops are used during treatment. Discomfort can develop afterward, particularly during the first few days of epithelial healing.
Will I be awake during the procedure?
Patients are generally awake. The treating specialist may provide medication to improve comfort.
How long does cross-linking take?
The treatment visit can take approximately one to two hours or longer, depending on the protocol and preparation requirements.
Can I wear contact lenses afterward?
Contact lenses should only be resumed when the treating specialist confirms that the cornea has healed sufficiently.
What are the potential risks?
Possible complications include infection, corneal haze, delayed epithelial healing, scarring, and changes in vision. Your surgeon will review individual risks.
Protect your vision with early evaluation.
If your prescription is changing frequently or your vision remains distorted despite corrective lenses, schedule an eye examination.
