Keratoconus is a progressive condition in which the cornea becomes thinner and develops an irregular, cone-like shape. These changes can cause blurred or distorted vision, glare, ghost images, increased astigmatism, frequent prescription changes, and difficulty seeing at night. Because the condition and its rate of progression differ from person to person, treatment must be based on detailed corneal imaging, visual needs, disease stability, and the condition of each eye.

What Is Keratoconus?

Keratoconus is a progressive corneal ectasia, a condition in which the structural integrity of the cornea gradually weakens, causing it to thin and assume an irregular, cone-like shape rather than maintaining its normal, dome-shaped curvature. This change in shape disrupts the cornea's ability to focus light accurately onto the retina, producing the visual distortions characteristic of the condition.

The cause of keratoconus is multifactorial. Genetic susceptibility plays a role, and a family history of the condition increases an individual's risk. Frequent, forceful eye rubbing, allergic eye disease, and certain connective tissue disorders, including Down syndrome, have also been associated with an elevated risk of developing or accelerating keratoconus. The condition typically becomes apparent in the late teens or early twenties and may progress over one to three decades before stabilizing.

Symptoms of Keratoconus

Keratoconus symptoms tend to evolve gradually and may initially be mistaken for ordinary refractive error. Common symptoms include blurred or distorted vision, ghosting or monocular double vision, glare and halos around lights, increased light sensitivity, frequent changes in glasses or contact lens prescription, increasing irregular astigmatism, and reduced quality of vision at night. As the condition progresses, standard glasses and soft contact lenses become less effective at correcting vision, and specialty lenses or surgical intervention may be required.

Diagnosis and Monitoring

Accurate diagnosis and ongoing monitoring are essential to managing keratoconus effectively. A comprehensive keratoconus evaluation at Princeton Eye Group includes slit-lamp examination of the cornea, corneal topography and tomography to map the shape and curvature of the corneal surface in detail, corneal thickness measurements to assess the degree of thinning, and comparison with prior imaging to determine whether the condition is stable or progressing.

Serial corneal imaging over time is one of the most important tools in keratoconus management, as it allows our team to detect subtle progression before it produces noticeable changes in vision and to make timely treatment decisions that protect the cornea's long-term health.

Treatment Based on Each Patient's Needs

Keratoconus does not follow a single, predictable course, and treatment should not follow a single, rigid sequence. At Princeton Eye Group, our approach to keratoconus treatment in Princeton, Monroe Township, & Somerset, NJ, is driven by each patient's current visual function, the stability or progression of their disease, and the specific characteristics of their cornea. The following clinical goals guide our treatment recommendations.

Improving Usable Vision

Glasses may provide adequate correction in earlier stages of keratoconus when the corneal irregularity is mild. As the cornea becomes more irregular, specialty contact lenses—including scleral, hybrid, and rigid gas permeable lenses—can provide significantly better visual correction by vaulting over the irregular corneal surface and replacing it with a smooth optical interface. Dr. Kevin Feng, our cornea and contact lens specialist and fellow of the Scleral Lens Society, brings dedicated expertise in fitting specialty lenses for patients with keratoconus and other irregular corneal conditions.

Slowing or Halting Progression

Corneal cross-linking may be recommended when serial imaging demonstrates progressive keratoconus or when the risk of progression is considered significant. Cross-linking uses ultraviolet light and riboflavin to strengthen the collagen bonds within the corneal stroma, halting the weakening process that drives keratoconus forward. It is the only treatment proven to stop disease progression and is a cornerstone of modern keratoconus management. Dr. Miedziak served as a site investigator in the pivotal Phase 3 clinical trial that led to FDA approval of corneal cross-linking in the United States — bringing firsthand research expertise to every cross-linking evaluation she performs.

Improving Corneal Shape in Selected Patients

For carefully selected patients, procedures such as CAIRS (Corneal Allogenic Intrastromal Ring Segments), CTAK (Corneal Tissue Addition Keratoplasty), and topography-guided PRK may be considered when improving corneal regularity or visual quality is an important clinical goal. These minimally invasive approaches aim to reshape and reinforce the cornea without replacing it, and are often performed in combination with cross-linking for a more comprehensive outcome. Dr. Tonk, whose expertise in these advanced techniques reflects his tenure at Bascom Palmer Eye Institute, is one of a small number of surgeons in the United States offering CAIRS and CTAK.

Corneal Transplantation

For advanced keratoconus involving substantial corneal scarring, extreme thinning, or vision that cannot be adequately rehabilitated with other approaches, partial- or full-thickness corneal transplantation may be considered. Princeton Eye Group performs the full range of modern transplant techniques, and our corneal surgeons work closely with patients to determine whether and when transplantation is the most appropriate path forward.

Individualized Treatment Planning

Not every patient needs surgery, and no single procedure is appropriate for every eye. The purpose of a keratoconus evaluation at Princeton Eye Group is to determine whether the disease is stable or progressing, how well the patient can currently see, and which combination of monitoring, specialty lenses, cross-linking, corneal reshaping, or transplantation is most appropriate for their individual situation.

What makes Princeton Eye Group's approach to keratoconus genuinely distinctive is the depth and breadth of our collaborative team. Dr. Anita Miedziak, Dr. Rahul Tonk, and Dr. Kevin Feng work together to provide multidisciplinary, coordinated keratoconus care that is rare in any practice setting. Keratoconus care is too often fragmented; patients may see different providers for contact lenses, cross-linking, and surgery with little communication between them.

At Princeton Eye Group, every aspect of a patient's keratoconus management—from specialty lens fitting and cross-linking to advanced corneal surgery and transplantation—is available within a single, integrated practice whose specialists collaborate directly on complex cases.
