Keratoconus. When the cornea progressively thins.
Keratoconus is a progressive condition that warps the cornea over time. A keratoconus specialist can confirm progression, discuss second-opinion questions, and determine whether corneal cross-linking can halt the progression before options narrow.

The cornea thins and bulges into an irregular cone shape.
In keratoconus, weakening collagen fibers cause the cornea to gradually lose its smooth dome shape and bulge outward into an irregular cone. The result is increasing astigmatism, blurry vision, and corrections that get harder to dial in with glasses or contact lenses.
Corneal cross-linking (CXL) uses riboflavin and ultraviolet light to strengthen corneal tissue and reduce the risk of further progression. The treatment decision depends on documented change, corneal thickness, age, vision, and the protocol considered.
What you may be noticing.
Increasing astigmatism, especially in young adulthood
Frequent prescription changes that don't fully correct vision
Blurry, distorted, or wavy vision
Glare and halos at night
Difficulty wearing contact lenses comfortably
Light sensitivity
Why it happens.
Genetic predisposition
Eye rubbing - repetitive trauma to the cornea
Allergic conditions causing chronic eye rubbing
Connective tissue disorders
Often diagnosed in late teens or early 20s

The right answer depends on your eyes, your prescription, and your life. Here's what we typically recommend - but the only way to know what fits you is a comprehensive evaluation.
Common questions.
Will CXL improve my vision?
CXL primarily stabilizes the cornea - preventing further worsening. Some patients see modest improvement over time, but the main benefit is preserving the vision and surgical options you have today.Can I have LASIK if I have keratoconus?
LASIK is generally avoided in keratoconus because removing corneal tissue can increase ectasia risk. After the cornea is evaluated and, when appropriate, stabilized, a cornea specialist can discuss glasses, specialty lenses, CTAK, phakic-lens options, or other individualized alternatives.Is CXL covered by insurance?
Many insurance plans now cover CXL for keratoconus. We verify benefits during your evaluation and walk you through any out-of-pocket costs.When should I get a second opinion for keratoconus?
Get a second opinion if your prescription or astigmatism keeps changing, if contact lenses no longer work well, or if you were told to wait despite signs of progression. A keratoconus consultation should include corneal topography and thickness mapping.
