Keratoconus often begins in the teenage years or early adulthood and may progress differently from one person to another.

What Are the Common Symptoms?

Keratoconus does not always cause obvious symptoms in the beginning.

Some people may first notice that their spectacle power keeps changing more frequently than expected.

Other symptoms can include:

• blurred or distorted vision

• frequent changes in spectacle power

• increasing astigmatism

• glare or halos around lights

• difficulty seeing clearly at night

• sensitivity to bright light

• difficulty getting clear vision even with new glasses

If your spectacle power changes repeatedly within a short period, especially at a younger age, it is worth getting the cornea checked.

Why Does Keratoconus Happen?

The exact cause of keratoconus is not always clear.

It may be influenced by a combination of genetic and environmental factors. A family history of keratoconus can increase the likelihood in some people.

Frequent or forceful eye rubbing is also associated with keratoconus and may contribute to worsening of the condition.

People with allergies may rub their eyes more often because of itching, so managing eye allergy and avoiding vigorous rubbing can be important.

However, keratoconus can also occur in people without any obvious family history or allergy.

How Is Keratoconus Diagnosed?

A routine spectacle-power test may suggest that something is unusual, but keratoconus is usually confirmed with detailed corneal measurements.

Your ophthalmologist may perform tests such as corneal topography or tomography.

These scans create a detailed map of the shape and curvature of the cornea. They can help identify early changes that may not be visible during a basic eye examination.

The doctor may also measure:

• corneal thickness

• corneal curvature

• spectacle power

• astigmatism

• overall eye health

These tests are also useful for monitoring whether the keratoconus is stable or progressing over time.

Does Keratoconus Always Get Worse?

Not necessarily.

Keratoconus can behave differently in different people.

In some patients, the condition may remain relatively stable. In others, the cornea may continue to change over time.

Progression is particularly important in younger patients because changes can sometimes occur more quickly.

Regular follow-up and repeat corneal scans help the ophthalmologist determine whether the condition is stable or worsening.

Can Glasses Correct Keratoconus?

In the early stages, glasses may provide useful vision.

As the cornea becomes more irregular, however, ordinary glasses may no longer give sufficiently clear vision.

Depending on the stage of keratoconus, the ophthalmologist may discuss options such as:

• glasses

• soft or specialised contact lenses

• rigid gas-permeable lenses

• scleral lenses

• corneal cross-linking

• other procedures in selected cases

The aim of treatment can be different for each patient. Some treatments are intended to improve vision, while others are intended to slow or stop progression.

That distinction is important.

What Is Corneal Cross-Linking?

If tests show that keratoconus is progressing, your ophthalmologist may discuss corneal cross-linking, often called CXL.

Cross-linking is a procedure designed to strengthen the cornea and reduce the risk of further progression.

It is not mainly performed to remove spectacle power or guarantee perfect vision. Its primary purpose is to help stabilise the cornea in suitable patients.

Can Keratoconus Be Treated With LASIK?

Keratoconus and suspected keratoconus need special care when considering laser vision correction.

Procedures that reshape the cornea, such as LASIK, may not be suitable for someone with keratoconus because the cornea is already structurally weaker or irregular.

This is one reason detailed corneal scans are performed before LASIK, SMILE or PRK.

If keratoconus is detected, your ophthalmologist can discuss other ways to improve vision depending on the stage of the condition.

Why Is Early Detection Important?

Keratoconus is easier to monitor and manage when it is identified early.

A young person whose spectacle power or astigmatism keeps changing should not simply keep replacing glasses without finding out why.

Early corneal scanning can help identify whether the changes are due to keratoconus and whether progression is occurring.

This is particularly important if there is a family history of the condition or frequent eye rubbing.

Keratoconus Care at Pixel Eye Hospital

If you have frequently changing spectacle power, increasing astigmatism or blurred vision that does not improve well with glasses, a detailed corneal evaluation may be useful.

At Pixel Eye Hospital in Kukatpally and Sanath Nagar, Hyderabad, patients can undergo corneal evaluation for keratoconus and discuss available treatment and vision-correction options with Dr. Krishna Poojita, Dr. Abdul Rasheed and the ophthalmology team.

The appropriate approach depends on factors such as your age, corneal shape, corneal thickness, vision and whether the condition is progressing.

Final Thoughts

Keratoconus is a condition in which the cornea becomes thinner and more irregular in shape, which can gradually affect vision.

It does not progress in the same way for everyone, and treatment depends on the stage of the condition.

Early diagnosis, avoiding vigorous eye rubbing and regular monitoring are important, particularly for younger patients.

If you are looking for a keratoconus evaluation in Hyderabad, you can consult Pixel Eye Hospital at Kukatpally or Sanath Nagar to understand the condition of your cornea and the options that may be suitable for you.
