What is Keratoconus?

Keratoconus is a progressive eye condition in which the cornea the clear front surface of the eye  becomes thin and bulges outward into a cone-like shape.

This irregular corneal shape causes blurred and distorted vision, making daily activities such as reading, driving, and screen use difficult. Early diagnosis and timely treatment can help slow disease progression and preserve vision quality.

Keratoconus: Causes, Symptoms & Advanced Treatment

Symptoms of Keratoconus

Patients with keratoconus may experience:

  • Blurred or distorted vision

  • Frequent changes in glasses number

  • Increased sensitivity to light and glare

  • Difficulty seeing at night

  • Eye strain and headaches

  • Double vision in one eye

  • Sudden worsening of eyesight

  • Difficulty wearing contact lenses comfortably

If these symptoms continue to worsen, a detailed corneal evaluation is recommended. 

Causes and Risk Factors of Keratoconus

The exact cause of keratoconus is not fully understood, but several factors may increase the risk:

  • Genetic or family history

  • Excessive eye rubbing

  • Chronic eye allergies

  • Weak corneal collagen structure

  • Long-term contact lens irritation

  • Connective tissue disorders

Keratoconus commonly develops during teenage years or early adulthood and may gradually progress over time. 

Stages of Keratoconus

Early Stage Keratoconus

Mild corneal thinning and slight vision distortion can often be managed with glasses or soft contact lenses.

Moderate Keratoconus

Vision becomes more irregular and patients may require specialized rigid gas permeable (RGP) or scleral lenses.

Advanced Keratoconus

Significant corneal thinning and scarring may occur, requiring surgical intervention such as corneal implants or corneal transplant surgery. 

Diagnosis of Keratoconus

At ASG Eye Hospital, advanced corneal imaging technologies help detect keratoconus at an early stage.

Corneal Topography

This advanced diagnostic test maps the surface curvature of the cornea and identifies irregular corneal patterns associated with keratoconus. 

Pachymetry

Pachymetry measures corneal thickness and helps assess disease progression.

Slit Lamp Examination

Specialists examine the cornea under magnification to detect thinning, scarring, and structural abnormalities. 

Keratoconus Treatment Options

Treatment depends on the severity and progression of the condition.

Glasses and Soft Contact Lenses

In the early stages, prescription glasses or soft contact lenses may improve visual clarity. 

Rigid Gas Permeable (RGP) Lenses

RGP lenses provide a smoother optical surface and improve vision in patients with irregular corneal shape. 

Scleral Lenses

Scleral lenses are large-diameter specialty lenses designed for advanced keratoconus patients who cannot tolerate regular lenses. 

Corneal Cross-Linking (C3R/CXL)

Corneal Cross-Linking is one of the most effective treatments for keratoconus. The procedure uses riboflavin (Vitamin B2) eye drops and ultraviolet light to strengthen corneal fibers and stop further progression of the disease. 

Intacs (Corneal Ring Implants)

Intacs are tiny ring segments inserted into the cornea to improve corneal shape and vision quality in selected cases. 

Corneal Transplant Surgery

In severe or advanced keratoconus cases with corneal scarring, corneal transplant surgery may be recommended to restore vision. 

Recovery After Keratoconus Treatment

Recovery depends on the treatment method:

  • Corneal Cross-Linking: Initial recovery in 3–7 days

  • Intacs Surgery: Approximately 1–2 weeks

  • Corneal Transplant: Several weeks to months for complete healing

Regular follow-up visits are important for monitoring corneal stability and vision improvement.

FAQ’s

Clear Answers for Better Vision

Is keratoconus curable?

Keratoconus cannot be completely cured, but modern treatments can effectively slow or stop disease progression and improve vision quality. 

The best treatment depends on the stage of the condition. Corneal Cross-Linking is commonly recommended to stop progression in early to moderate stages. 

If left untreated, severe keratoconus can significantly affect vision and quality of life, but early treatment can help preserve eyesight.

Most keratoconus procedures are minimally invasive and performed under local anesthesia, causing minimal discomfort.

LASIK is generally not recommended for keratoconus patients because the cornea is already thin and weak.

The procedure usually takes around 30 to 60 minutes and is performed as a day-care treatment.
