    What is C3R for Keratoconus?

    C3R, also known as corneal collagen cross-linking (CXL), is a treatment used to strengthen the cornea in patients with keratoconus. Keratoconus causes the cornea to become thinner and gradually change into a more cone-like shape, which can lead to blurred or distorted vision.

    During C3R treatment, riboflavin (vitamin B2) eye drops are applied to the cornea and activated using controlled ultraviolet-A light. This process increases the bonding between collagen fibres within the cornea, helping strengthen its structure and slow further progression of keratoconus.

    Why Choose C3R?

    Corneal Strengthening

    C3R helps strengthen the weakened corneal structure and can help slow the progression of keratoconus.

    Helps Stabilise Keratoconus

    By increasing collagen cross-linking within the cornea, the treatment helps maintain greater structural stability.

    Minimally Invasive Treatment

    C3R is performed using riboflavin eye drops and controlled ultraviolet-A light without removing corneal tissue.

    Protects Future Vision

    Early treatment may help prevent further corneal weakening and reduce the risk of progressive visual deterioration.

    Preserves Corneal Structure

    C3R works by strengthening the existing corneal collagen rather than replacing or removing the cornea.

    Personalised Treatment

    A detailed corneal examination and mapping help the ophthalmologist assess the condition and determine the appropriate treatment approach.

    Who Can Benefit from C3R for Keratoconus

    SC3R is generally considered for patients with keratoconus where examination shows evidence of progression or a risk of further corneal weakening.

    Progressive Keratoconus

    C3R may be recommended when tests show that keratoconus is progressing and the cornea is becoming weaker or more irregular.

    Corneal Weakening

    Patients with a structurally weakened cornea may be assessed for cross-linking to help strengthen and stabilise the corneal tissue.

    C3R Eligibility Assessment

    A comprehensive eye examination, corneal topography and assessment of corneal thickness help determine whether C3R is appropriate for the individual patient.

    Every patient undergoes a detailed corneal evaluation to determine whether C3R

    is the most appropriate treatment option.

    What Happens During the Procedure?

    1

    Anaesthetic Eye Drops

    The eye is numbed with local anaesthetic drops for comfort during treatment.

    2

    Corneal Preparation

    The cornea is prepared according to the treatment protocol recommended by the ophthalmologist.

    3

    Riboflavin Application

    Riboflavin (vitamin B2) eye drops are applied to the cornea to allow adequate absorption.

    4

    UV-A Light Exposure

    Controlled ultraviolet-A light is applied to activate the riboflavin and promote collagen cross-linking.

    5

    Corneal Stabilisation

    The cross-linking process strengthens the corneal structure and helps slow the progression of keratoconus.

    Recovery After C3R

    • Follow your ophthalmologist's prescribed eye-drop and aftercare instructions.
    • Temporary discomfort, watering or light sensitivity may occur during the early recovery period.
    • Vision may remain hazy for a period after treatment and gradually improve.
    • Avoid rubbing or touching the treated eye during recovery.
    • Attend scheduled follow-up examinations to monitor corneal healing and stability.

    Is C3R Right for You?

    C3R may be suitable for patients with keratoconus where clinical examination and corneal imaging indicate progression or a need for corneal strengthening. Treatment suitability depends on factors such as corneal thickness, corneal shape, disease progression and overall eye health.

    A detailed corneal examination is essential before treatment. Your ophthalmologist will review your corneal mapping and other test results to determine whether C3R is appropriate for your eyes.

    FREQUENTLY ASKED QUESTIONS

    Frequently Asked Questions

    1. Is SMILE eye surgery painful?
    SMILE eye surgery is generally not painful. Anaesthetic eye drops are used before the procedure to numb the eye, and most patients experience only mild pressure during treatment. Some temporary irritation or watering may occur afterwards but usually settles within a short period.
    2. How long do the results of SMILE surgery last?
    The vision correction achieved through SMILE is intended to be permanent because the cornea is permanently reshaped. However, natural age-related changes, such as presbyopia or cataracts, can still affect vision later in life.
    3. Can both eyes be treated on the same day?
    Yes. In most cases, both eyes are treated during the same appointment, making the process more convenient and allowing recovery to begin immediately.
    4. When can I drive after SMILE surgery?
    Many patients are able to drive within one or two days after surgery, provided their vision meets the legal driving standard and their ophthalmologist confirms it is safe to do so.
    5. Can I wear contact lenses before my SMILE consultation?
    Contact lenses should usually be discontinued before the pre-operative assessment, as they can temporarily alter the shape of the cornea. Your ophthalmologist will advise how many days to stop wearing them based on the type of lenses you use.
    6. Will I still need glasses after SMILE surgery?
    Most patients achieve significantly reduced dependence on glasses or contact lenses. However, some people may still require glasses for specific tasks or later in life due to natural ageing of the eyes.

      Revolutionizing Keratoconus Care: Precision Corneal Reshaping

      At Dr. P. S. Hardia Advanced Eye Surgery and Research Institute, we offer INTACS (Intracorneal Ring Segments), a breakthrough technology specifically designed for the management of Keratoconus. Keratoconus is a progressive condition where the cornea thins and bulges into a cone-like shape, causing severe visual distortion. INTACS are microscopic, clear segments inserted into the corneal stroma to flatten the bulge and restore a more natural, spherical shape to the eye.

      This procedure is ideal for patients who are intolerant to contact lenses or for those whose Keratoconus is progressing despite other treatments. Unlike traditional surgeries, INTACS do not involve removing any corneal tissue; instead, they act as structural supports to reinforce the cornea. This effectively reduces irregular astigmatism and myopia, often significantly improving the patient’s best-corrected vision and quality of life.

      Backed by our Guinness World Record legacy and extensive experience in complex corneal cases, we provide a personalized approach to INTACS implantation. We often combine INTACS with C3R (Corneal Collagen Cross-linking) for a dual-action result: C3R to stop the progression and INTACS to improve the visual shape. Our commitment to using high-definition corneal mapping ensures that every segment is placed with microscopic precision for maximum visual stability.

      The Structural Advantages of INTACS Technology

      • Microscopic Precision Reshaping: INTACS flatten the steep "cone" of Keratoconus, significantly reducing distorted vision and high irregular astigmatism.
      • Enhanced Contact Lens Tolerance: By smoothing the corneal surface, INTACS make it much easier and more comfortable for patients to wear contact lenses if needed.
      • No Tissue Removal: Unlike laser surgery, INTACS preserve all your natural corneal tissue, maintaining the eye’s essential biomechanical strength.
      • Long-term Structural Support: The segments act as a permanent internal "brace," helping to maintain the corrected corneal shape for years to come.
      • Minimally Invasive Day-Care: The procedure is performed under local anesthesia in minutes, allowing you to return to your normal routine with minimal downtime.

      Refined by Advanced Corneal Remodeling Technology

      By utilizing ultra-thin, biocompatible ring segments and femtosecond laser precision, we reshape the irregular cornea from within, providing a stable structural foundation that enhances visual clarity and contact lens comfort.

      FREQUENTLY ASKED QUESTIONS

      Frequently Asked Questions

      What exactly are INTACS?
      INTACS are two tiny, clear, crescent-shaped rings made of a biocompatible material (the same used in cataract lenses for decades). They are inserted into the outer edge of the cornea to flatten the center bulge caused by Keratoconus.
      Can INTACS cure Keratoconus?
      There is no permanent "cure" for Keratoconus, but INTACS are highly effective at managing the condition. They improve the shape of the eye, which makes vision clearer and more stable.
      Is the procedure reversible?
      Yes. Unlike LASIK or other laser surgeries, INTACS do not remove any tissue. If your prescription changes significantly in the future, the segments can be removed or replaced.
      Who is a good candidate for INTACS?
      You may be a candidate if you have Keratoconus, have a cornea that is not too thin, and are unable to achieve functional vision with glasses or contact lenses. A detailed corneal mapping (Topography) is required to confirm candidacy.
      Will I still need glasses after INTACS?
      While INTACS significantly improve your natural vision and reduce astigmatism, most patients still require a mild prescription in glasses or specialized contact lenses to achieve their "best" vision.
