The good news is that there are different ways to improve vision in keratoconus, depending on how advanced the condition is and whether the cornea is stable or still changing.

One important point to understand is that improving vision and stopping the progression of keratoconus are not always the same thing. Treatments such as glasses and contact lenses mainly help improve vision, while procedures such as corneal cross-linking are primarily used to strengthen the cornea and reduce further progression.

1. Glasses

In the early stages of keratoconus, ordinary spectacles may still provide good vision.

If the cornea has only mild irregularity, changing the spectacle prescription may be enough to correct short-sightedness and astigmatism.

However, as keratoconus progresses, the shape of the cornea can become more irregular. At this stage, glasses may no longer provide the same level of clarity because spectacles cannot completely correct an irregular corneal surface.

This is when specialised contact lenses may be considered.

2. Soft Contact Lenses

Some patients with mild keratoconus may be able to use specially designed soft contact lenses.

These lenses can correct the spectacle power and some astigmatism while providing better comfort for certain patients.

However, they may not provide enough clarity when the corneal shape becomes significantly irregular.

The type of contact lens that works best depends on the shape of the cornea and the patient's visual requirements.

3. Rigid Gas-Permeable Contact Lenses

Rigid Gas-Permeable lenses, commonly called RGP lenses, are frequently used when glasses or standard soft contact lenses no longer provide adequate vision.

Unlike a soft lens that follows the irregular shape of the cornea, an RGP lens creates a smoother optical surface over it.

This can significantly improve visual clarity in many patients with keratoconus.

However, fitting an RGP lens for keratoconus requires careful measurements. Some patients may also need time to become comfortable wearing them.

4. Scleral Lenses

For patients with more irregular corneas or difficulty tolerating conventional contact lenses, scleral lenses may be considered.

A scleral lens is larger than a regular contact lens. Instead of resting mainly on the cornea, it rests on the white part of the eye, called the sclera.

A layer of fluid remains between the lens and the cornea, creating a smoother surface for light to pass through.

This can help provide clearer vision in patients with moderate or advanced keratoconus.

Scleral lenses can also be useful when the corneal surface is particularly irregular, but they need to be individually fitted.

5. Corneal Cross-Linking

Corneal cross-linking, or CXL, is an important treatment for patients whose keratoconus is progressing.

Cross-linking uses riboflavin and controlled ultraviolet light to strengthen the corneal tissue.

However, patients should understand that cross-linking is mainly performed to stabilise the cornea, rather than to provide immediate freedom from glasses.

Some people may notice an improvement in corneal shape or vision after cross-linking, but this cannot be guaranteed.

After the cornea becomes stable, glasses or specialised contact lenses may still be needed to achieve the best possible vision.

6. Intracorneal Ring Segments

In selected patients, intracorneal ring segments may be considered.

These are small curved segments placed within the cornea to help change its shape and reduce some of the irregularity caused by keratoconus.

They may improve vision or make the corneal shape easier to correct with glasses or contact lenses in certain cases.

However, they are not suitable for every patient and do not replace cross-linking when the keratoconus is actively progressing.

The decision depends on factors such as the shape, thickness and clarity of the cornea.

7. Laser-Based Treatment in Selected Patients

Standard LASIK is generally not suitable for keratoconus, because the cornea is already structurally weak and irregular.

However, in carefully selected patients with suitable corneal measurements, specialised treatments such as topography-guided surface laser treatment combined with corneal cross-linking may sometimes be considered.

These procedures are very different from routine LASIK and require detailed corneal assessment.

They are not appropriate for every patient with keratoconus.

8. Implantable Lenses in Selected Cases

Some patients with stable keratoconus may also have significant remaining spectacle power even when their corneal condition has been addressed.

In selected cases, an implantable lens such as a phakic intraocular lens may be discussed to correct part of the remaining refractive error.

This does not treat the keratoconus itself and is only considered after carefully assessing the stability of the cornea and the overall condition of the eye.

9. Corneal Transplant for Advanced Keratoconus

Most people with keratoconus do not require a corneal transplant.

However, in advanced cases where the cornea becomes severely irregular, very thin or develops significant scarring, glasses and contact lenses may no longer provide useful vision.

In these situations, a corneal transplant may be considered.

The surgeon may replace part or all of the affected corneal tissue depending on the condition of the eye.

Because transplantation is a major eye surgery, it is generally considered when less invasive options are no longer able to provide adequate vision.

Which Option Is Right for You?

There is no single treatment that is suitable for every person with keratoconus.

The ophthalmologist may consider:

• your age

• how advanced the keratoconus is

• whether it is progressing

• corneal thickness

• corneal shape

• the presence of scarring

• your current spectacle power

• how well you see with glasses

• whether you can comfortably wear contact lenses

• your daily visual requirements

For one patient, glasses may still be enough. Another may benefit from scleral lenses, while someone with progressive keratoconus may first need cross-linking to stabilise the cornea.

That is why treatment is usually planned step by step rather than choosing one procedure for everyone.

Keratoconus Treatment at Pixel Eye Hospital

If your spectacle power keeps changing, your vision remains blurred despite new glasses, or you have already been diagnosed with keratoconus, detailed corneal scans can help determine the next step.

At Pixel Eye Hospital in Kukatpally and Sanath Nagar, Hyderabad, patients can consult Dr. Krishna Poojita, Dr. Abdul Rasheed and the ophthalmology team for keratoconus evaluation and discussion of suitable vision-correction options.

The goal is not only to improve vision where possible, but also to understand whether the keratoconus is stable or needs treatment to prevent further progression.

Final Thoughts

Vision in keratoconus can be improved in several ways, ranging from glasses and specialised contact lenses to cross-linking, selected corneal procedures and, in advanced cases, corneal transplantation.

The right option depends on the stage and stability of the condition.
