Keratoconus Treatment at Vision Eye Hospital: Diagnosis and Advanced Treatment Options
Sep 5, 2026
Keratoconus is a progressive corneal condition in which the normally round, dome-shaped cornea becomes thinner and gradually bulges outward into a cone-like shape. This irregular corneal shape can cause blurred or distorted vision, increasing astigmatism, glare and difficulty seeing clearly at night.
The condition often begins during the teenage years or early adulthood and may progress over time. Early diagnosis is important because appropriate treatment can help stabilise the cornea and reduce the risk of further progression.
At Vision Eye Centre in Delhi, keratoconus care includes detailed corneal evaluation, specialised contact lens management, corneal cross-linking, intracorneal ring segments and corneal transplantation for selected advanced cases.
What Is Keratoconus?
Keratoconus is a disorder of the cornea, the transparent front surface of the eye.
In a healthy eye, the cornea has a relatively regular curved shape that helps focus incoming light. With keratoconus, the cornea becomes progressively thinner and develops an irregular, cone-like protrusion.
Because of this irregular shape, light may not focus properly on the retina. This can result in:
- Blurred vision
- Distorted or stretched vision
- Irregular astigmatism
- Increased sensitivity to light
- Glare and halos around lights
- Difficulty driving at night
- Frequent changes in glasses prescription
- Difficulty achieving clear vision with regular spectacles
The exact cause of keratoconus is not fully understood. Genetics may play a role, and factors such as frequent eye rubbing and certain allergic or atopic conditions may increase the risk.
What Are the Early Signs of Keratoconus?
Keratoconus can develop gradually, so early symptoms may sometimes be mistaken for an ordinary change in spectacle power.
You should consider a comprehensive corneal examination if you experience:
Frequent Changes in Glasses Power
Repeated changes in your spectacle prescription, especially increasing astigmatism, can be an indication that the shape of the cornea is changing.
Blurred or Distorted Vision
Vision may not simply appear blurry. Straight lines can sometimes look bent, stretched or irregular.
Increasing Astigmatism
Irregular astigmatism is commonly associated with keratoconus and may become increasingly difficult to correct with ordinary spectacles.
Glare and Halos
Patients may notice halos around lights, particularly at night. This can make driving more uncomfortable.
Light Sensitivity
Increased sensitivity to bright light can occur as the corneal shape becomes more irregular.
Difficulty Seeing Clearly Despite New Glasses
If you continue to experience poor-quality vision even after changing your glasses prescription, a corneal assessment may be useful.
Why Early Diagnosis of Keratoconus Matters
One of the most important aspects of keratoconus management is identifying progression early.
Not every patient with keratoconus requires the same treatment. Some patients may have a relatively stable condition that can be managed with vision correction and monitoring, while others may have progressive corneal thinning that requires a procedure to stabilise the cornea.
Early diagnosis allows the ophthalmologist to:
- Assess the corneal shape
- Measure corneal thickness
- Identify irregular astigmatism
- Monitor changes over time
- Determine whether the condition is progressing
- Decide whether treatment is necessary
- Select an appropriate treatment strategy
The goal is not simply to improve today's vision but also to protect the cornea from further progression where treatment is indicated.
How Is Keratoconus Diagnosed?
A routine eye test may not be sufficient to fully evaluate keratoconus.
A specialist examination can include detailed assessment of the cornea using technologies such as corneal topography and tomography.
Corneal Topography
Corneal topography creates a map of the corneal surface and helps identify abnormalities in its curvature.
This can be particularly useful for detecting irregular corneal shape associated with keratoconus.
Corneal Tomography
Tomographic imaging provides additional information about the front and back surfaces of the cornea and can help evaluate corneal structure.
Pachymetry
Pachymetry measures corneal thickness. Since progressive thinning is an important feature of keratoconus, thickness measurements can contribute to treatment planning.
Vision Eye Centre lists the Oculus Pentacam among its diagnostic equipment, along with other ophthalmic diagnostic systems.
Keratoconus Treatment: Is Surgery Always Necessary?
No.
Keratoconus treatment depends on the severity of the condition, whether it is progressing, the quality of vision and the patient's individual corneal characteristics.
Treatment may range from simply correcting vision to procedures designed to stabilise or reshape the cornea.
Common treatment approaches include:
- Eyeglasses
- Soft contact lenses
- Rigid gas permeable contact lenses
- Hybrid contact lenses
- Scleral lenses
- Corneal cross-linking
- Intracorneal ring segments
- Corneal transplantation
The appropriate option should be determined after a detailed examination rather than simply based on the stage name of the disease.
1. Eyeglasses for Early Keratoconus
In very early keratoconus, spectacles may provide satisfactory vision.
Glasses can correct certain amounts of myopia and astigmatism, but they may become less effective as the cornea develops greater irregularity.
If vision remains good with spectacles and the cornea is stable, the ophthalmologist may recommend regular monitoring.
2. Specialised Contact Lenses
As keratoconus progresses, standard spectacles or soft contact lenses may no longer provide sufficient visual clarity.
Specialised lenses can create a more regular optical surface in front of the irregular cornea.
Rigid Gas Permeable Lenses
RGP lenses have a firm optical surface and can provide clearer vision in patients with irregular corneal curvature.
Hybrid Lenses
Hybrid lenses combine a rigid central portion with a softer outer section. They may provide a balance between optical correction and wearing comfort for selected patients.
Scleral Lenses
Scleral lenses are larger lenses that rest on the sclera rather than directly on the cornea. They can create a fluid reservoir over the corneal surface and may be useful for patients with more advanced corneal irregularity.
Vision Eye Centre's keratoconus service specifically lists RGP, hybrid and scleral lenses among its treatment options.
3. Corneal Cross-Linking for Keratoconus
Corneal cross-linking, commonly called CXL, is primarily intended to strengthen the cornea and slow or stop progression of keratoconus.
It is not simply a procedure to make vision immediately clear.
During corneal cross-linking, riboflavin eye drops are used with controlled ultraviolet light exposure. The treatment promotes additional bonding between collagen fibres within the cornea, helping strengthen the corneal structure.
Vision Eye Centre lists corneal cross-linking as an important treatment for early to moderate keratoconus.
Why Is Cross-Linking Important?
The main objective of CXL is corneal stabilisation.
If a patient's keratoconus is progressing, stabilising the cornea may help reduce the risk of further thinning and deformation.
However, cross-linking is not appropriate for every patient. The ophthalmologist must first evaluate factors such as corneal thickness, disease progression and overall corneal condition.
4. Intracorneal Ring Segments
Intracorneal ring segments, or ICRS, are small arc-shaped implants placed within the cornea.
They can alter the shape of the cornea and may help reduce some of the irregularity associated with keratoconus.
According to Vision Eye Centre, ICRS may also make contact lens fitting easier in selected patients and can potentially delay the need for corneal transplantation in appropriate cases.
ICRS is not suitable for every keratoconus patient. Detailed corneal measurements are necessary before considering the procedure.
5. Corneal Transplantation for Advanced Keratoconus
A corneal transplant may be considered when keratoconus becomes advanced and the cornea develops significant thinning, scarring or visual impairment that cannot be adequately managed with other approaches.
During keratoplasty, damaged corneal tissue is replaced with healthy donor tissue.
The type of corneal transplantation depends on which layers of the cornea are affected and the individual clinical situation.
Dr. Tushar Grover's listed corneal expertise includes advanced transplantation procedures such as penetrating keratoplasty and lamellar techniques including DALK, DSAEK and DMEK.
A corneal transplant is generally considered a more advanced treatment option rather than the first-line approach for every keratoconus patient.
How Do Doctors Decide Which Keratoconus Treatment Is Right?
There is no single treatment that is best for every patient.
The treatment plan may depend on:
- Patient's age
- Severity of keratoconus
- Evidence of progression
- Corneal thickness
- Corneal shape
- Degree of irregular astigmatism
- Quality of vision
- Contact lens tolerance
- Presence of corneal scarring
- Previous treatments
- Individual visual requirements
For example, a patient with early and stable keratoconus may only require spectacles, contact lenses and regular monitoring.
A patient with documented progression may be considered for corneal cross-linking.
Someone with significant corneal irregularity may require specialised contact lenses or potentially ICRS, while advanced disease with scarring may require corneal transplantation.

Why You Should Avoid Rubbing Your Eyes
Frequent and vigorous eye rubbing is associated with keratoconus risk and may contribute to progression.
If you have keratoconus or are at risk of developing it, try to avoid rubbing your eyes.
If allergies or itching are causing you to rub your eyes frequently, speak with an eye specialist about appropriate management rather than repeatedly rubbing the eyes.
Parents should also pay attention when children or teenagers frequently rub their eyes, particularly if they complain of worsening vision or require frequent changes in glasses.
Can Keratoconus Be Completely Cured?
Keratoconus is generally considered a chronic corneal condition rather than something that can simply be eliminated with medication.
However, modern treatment can help manage its effects.
The objectives of treatment may include:
- Stabilising progressive keratoconus
- Improving functional vision
- Correcting irregular astigmatism
- Improving contact lens tolerance
- Managing corneal scarring
- Preserving the cornea
- Avoiding or delaying transplantation when appropriate
Corneal cross-linking is primarily used to stabilise progressive disease, while contact lenses and other procedures may be used to improve visual function.
When Should You See a Keratoconus Specialist?
You should consider a detailed corneal evaluation if you experience:
- Repeated changes in glasses prescription
- Increasing astigmatism
- Blurred or distorted vision
- Difficulty seeing at night
- Halos around lights
- Increasing glare
- Poor vision despite updated glasses
- Frequent eye rubbing
- A family history of keratoconus
- A previous diagnosis of keratoconus
Early evaluation is particularly important for teenagers and young adults because keratoconus can progress during these years.
Frequently Asked Questions About Keratoconus Treatment
What is the main cause of keratoconus?
The exact cause is not fully understood. Genetic factors may contribute, while frequent eye rubbing and certain allergic or atopic conditions may increase the risk.
Can keratoconus be cured?
There is no simple permanent cure that reverses keratoconus in every patient. However, treatments can stabilise progression and improve functional vision. The appropriate treatment depends on the individual's corneal condition.
Is corneal cross-linking necessary for everyone with keratoconus?
No. Cross-linking is primarily considered when there is evidence that keratoconus is progressing and the cornea is suitable for the procedure. A specialist examination is necessary to determine whether CXL is appropriate.
Can I wear contact lenses if I have keratoconus?
Yes. Many keratoconus patients use specialised contact lenses, including RGP, hybrid or scleral lenses. The appropriate lens depends on corneal shape and individual visual needs.
When is a corneal transplant required for keratoconus?
A transplant may be considered in advanced keratoconus when the cornea is severely thin or scarred, or when satisfactory vision cannot be achieved through other treatment approaches.
Does keratoconus get worse with age?
Keratoconus can progress, particularly during younger years, although the course varies between individuals. Regular monitoring helps the ophthalmologist identify changes in corneal shape and thickness.
Can eye rubbing make keratoconus worse?
Frequent eye rubbing is considered an important risk factor associated with keratoconus and may contribute to disease progression. Avoiding vigorous eye rubbing is advisable, especially in people with keratoconus or a predisposition to it.
Take the First Step Toward Better Keratoconus Management
Keratoconus should not be evaluated only by how clearly you can see with your current glasses. The condition involves changes in the shape and structure of the cornea, so detailed corneal assessment is an important part of diagnosis and treatment planning.
From specialised contact lenses and corneal cross-linking to intracorneal ring segments and corneal transplantation for advanced cases, treatment should be selected according to the individual patient's corneal condition.
