Keratoconus
Keratoconus is a progressive eye condition that causes the cornea to thin and take on a cone-like shape, leading to distorted vision, increased astigmatism, and difficulty with standard eyeglasses or contact lenses. As the condition advances, vision may become increasingly blurred, making daily activities more challenging.
At I Love LASIK, Dr. Samer Khosrof provides advanced keratoconus treatments, including corneal cross-linking (CXL) to strengthen the cornea and EVO ICL™ for patients seeking long-term vision correction. Early diagnosis and treatment can help manage the progression of keratoconus and preserve vision.
What is Keratoconus?
Keratoconus is a progressive eye condition that weakens the cornea—the transparent, dome-shaped surface at the front of the eye. As the corneal structure deteriorates, it thins and bulges forward into a cone-like shape, distorting how light enters the eye. This irregularity leads to blurred or distorted vision, astigmatism, increased nearsightedness, and difficulty achieving clear vision with eyeglasses or soft contact lenses. The progression of keratoconus varies from person to person, sometimes advancing rapidly and other times developing over years. Early diagnosis through a comprehensive eye exam is essential to preserving visual acuity and preventing severe

What Causes Keratoconus?
The exact cause of keratoconus remains unclear, but research suggests a combination of genetic and environmental factors. Many individuals diagnosed with keratoconus have a family history of the condition, with

estimating that 1 in 10 cases may be hereditary. External influences, such as frequent eye rubbing, poorly fitted contact lenses, chronic eye irritation, and underlying eye diseases, may also contribute to corneal weakening. Certain medical conditions, including asthma, Down syndrome, and retinitis pigmentosa, have been linked to a higher risk of developing keratoconus. Because the condition often begins in adolescence or early adulthood, regular eye exams are crucial for early detection and intervention.
Symptoms of Keratoconus
Keratoconus often begins in the late teenage years or early adulthood, with symptoms that gradually worsen over time. Because the cornea becomes irregularly shaped, vision can become increasingly distorted, making everyday tasks more challenging. Symptoms may vary between eyes and can include:
- Blurred or distorted vision that makes it difficult to see fine details
- Increased nearsightedness or astigmatism, leading to frequent changes in eyeglass or contact lens prescriptions
- Sensitivity to light and glare, making bright lights uncomfortable and nighttime driving difficult
- Halos or streaks of light around bright objects
- Ghost images or double vision, even when looking through one eye
- Difficulty wearing contact lenses, especially soft lenses that may no longer fit due to the cornea’s cone-like

As keratoconus progresses, standard vision correction methods like eyeglasses or soft contact lenses may become less effective, requiring specialized treatment to maintain visual acuity. Regular eye exams are essential for detecting changes and managing the condition before it significantly impacts daily life.
While there is no cure for keratoconus, advancements in ophthalmology have led to highly effective treatments that can slow or stop its progression and, in some cases, restore clearer vision. The best approach depends on the severity of the condition, the stability of the cornea, and individual vision goals.
Contact Lenses for Keratoconus
In the early stages of keratoconus, eyeglasses or soft contact lenses may provide adequate vision correction. However, as the cone-like shape of the cornea worsens, standard lenses often become ineffective. Many patients benefit from:
- Rigid gas permeable contact lenses (RGPs) – These gas permeable contact lenses create a smooth refractive surface over the cornea, improving clarity.
- Hybrid lenses – A combination of rigid gas and soft lenses, designed for comfort and stability.
- Scleral contact lenses – Larger lenses that vault over the cornea, providing sharper vision while protecting the eye’s surface.
Corneal Cross-Linking (CXL) for Keratoconus
Corneal collagen cross-linking (CXL) is a minimally invasive procedure designed to strengthen the cornea and prevent further bulging. By applying riboflavin (vitamin B2) eye drops followed by controlled ultraviolet (UV) light exposure, CXL increases the bonds between collagen fibers within the corneal tissue, stabilizing the structure and reducing the risk of worsening vision. The FDA-approved treatment has been instrumental in delaying or preventing the need for a corneal transplant in many patients. CXL does not reverse keratoconus, but it can significantly slow the progression of the disease and help preserve visual acuity.

Intacs® Corneal Implants
For some patients with keratoconus, Intacs may be a helpful option to improve vision and corneal shape. These small, curved inserts are placed just beneath the surface of the cornea in a quick, office-based procedure. Intacs work by gently flattening the cornea, which can reduce irregularity and improve how light enters the eye. While not a cure, they can be an effective part of a broader treatment plan—especially for patients who are no longer getting adequate vision correction from glasses or contacts.
Corneal Transplant for Advanced Keratoconus
In severe cases where corneal scarring or extreme thinning compromises vision, a corneal transplant may be necessary. This procedure replaces the damaged cornea with healthy donor tissue. While typically successful, a transplant is considered a last resort when other keratoconus treatment options no longer provide sufficient vision correction.
Early intervention with eye exams and specialized eye care can help prevent progression and maintain eye health.

EVO ICL™ for Keratoconus
For patients with keratoconus symptoms who seek long-term vision correction, the EVO ICL (Implantable Collamer™ Lens) may be an option. This advanced refractive surgery places a biocompatible lens inside the eye, providing clear vision without removing corneal tissue. EVO ICL is often performed after corneal cross-linking, once the cornea has stabilized. Unlike LASIK, which removes tissue to reshape the cornea, EVO ICL works with the eye’s natural structure, making it a safer alternative for patients with keratoconus.
EVO ICL has been a highly effective option for improving vision in patients with keratoconus. We’ve seen excellent outcomes, with many individuals achieving sharper, more stable vision and reducing their reliance on glasses or contact lenses. This advanced lens implant offers a valuable path forward for those seeking lasting vision correction while preserving the natural structure of the eye.

The exact cause of keratoconus is not fully understood, but research suggests a combination of genetic and environmental factors. The condition has been linked to chronic eye rubbing, ocular allergies, and certain connective tissue disorders.
Keratoconus is typically diagnosed through a comprehensive eye exam, which may include:
- Corneal topography – A detailed map of the cornea to detect irregularities.
- Keratometry – A test that measures the curvature of the cornea.
- Slit-lamp examination – A close-up evaluation of the eye’s surface and structure.
Yes. Frequent or aggressive eye rubbing can contribute to corneal thinning and may worsen keratoconus. If you suffer from ocular allergies, it’s essential to avoid rubbing your eyes and consider using prescribed allergy eye drops to minimize irritation.
During corneal collagen cross-linking (CXL):
- Riboflavin eye drops (vitamin B2) are applied to the cornea.
- The epithelium (the cornea’s surface layer) may be removed to allow better absorption.
- The cornea is exposed to ultraviolet (UV) light, which strengthens collagen fibers and stabilizes the cornea’s shape.
The entire procedure is performed in-office and typically takes 30 to 45 minutes per eye.
Most patients experience mild discomfort, light sensitivity, and blurred vision for a few days following CXL. Prescription eye drops are provided to aid healing, and contact lenses should be avoided until the cornea recovers. Visual improvement occurs gradually over several weeks to months.
There is no cure for keratoconus, but treatments like corneal cross-linking (CXL) can halt or slow the progression of the disease, helping to preserve vision.
No, LASIK is not a recommended treatment for keratoconus. Because LASIK removes corneal tissue to reshape the eye, it can further weaken an already thinned or irregular cornea, worsening vision and increasing the risk of complications such as corneal ectasia.
For patients with keratoconus, safer and more effective options include corneal cross-linking (CXL) to strengthen the cornea and EVO ICL™, which provides vision correction without altering the corneal structure.
Keratoconus does not cause complete blindness, but it can lead to severe vision loss if left untreated. In advanced cases, a corneal transplant may be required.
