Why you can trust this page
The description of Intracorneal Ring Segments (ICRS / Intacs) on this page reflects how the service is offered at Neera Eye Centre, Darya Ganj, by the team led by Dr. Neera Agrawal.
Where a recovery time or a fee is not given as a fixed number, that is deliberate. Both depend on your examination, and both are explained before you decide.
This page is written for patients considering the service. It is general information, not a personalised treatment plan.
Service Overview
Intacs (intracorneal ring segments) are thin clear arcs slid into a channel in the cornea to flatten a cone a little.
You typically cannot get a usable image from glasses, and even rigid lenses have become hard to wear. The aim is a more regular shape — often so a lens will sit — not a promise of 6/6 without correction.
Channels are usually made with a femtosecond laser. The rings stay inside the cornea; they can be removed if they do not help.
Rings do not stop keratoconus on their own. Thin, scarred, or very steep corneas may be better with C3R alone, a scleral lens, or DALK. We will not implant rings as theatre for a cone that needs a graft.
What It Covers
Thickness and shape to see if a channel is safe.
Whether cross-linking is needed to freeze progression.
Arc length and thickness matched to the cone, not a one-size insert.
Channel, insert, check — usually day care.
Glasses or specialty lenses after the shape has settled.
Who It Is For
Clear central cornea, enough thickness for a channel.
When a slightly flatter cone may make a lens possible again.
Those eyes need a different plan.
Cost
The cost of Intracorneal Ring Segments (ICRS / Intacs) at Neera Eye Centre depends on your examination and the plan your eyes actually need. We confirm a written estimate at consultation, before anything is booked.
There is no single figure that fits every eye. The technique, whether one or both eyes are treated, and any other condition found on examination can change the plan.
Your scans, the treatment that suits your eye, and whether extra care is needed for a second condition. The written estimate lists what is included before a date is fixed.
How It Works
The eye is numbed. You should not feel pain — pressure is common.
A laser or mechanical path is made in the stroma.
The ring segment is slid into place.
Position and inflammation are checked; vision is not judged on day one.
Before and after
What the first days look like depends on whether this is a scan, medical treatment, or a procedure. At Neera Eye Centre we explain drops, precautions, and the review date before anything is scheduled.
Bring earlier reports, your current glasses, and a list of eye drops or medicines. Tell us about diabetes, allergies, blood thinners, and any recent redness or injury.
Follow the plan you are given — observation, drops, or a procedure date. Avoid rubbing the eye. Call us the same day if pain, redness, or blurred vision gets worse instead of settling.

Timing
Come in when symptoms affect reading, driving, work, or comfort, or when another doctor has asked you to get this checked. You do not need to wait until a problem is severe.
A consultation is how we tell you whether this service is the right next step, or whether observation or a different treatment suits your eyes better.
Why Choose Us
Keratoconus care at Neera Eye Centre, Darya Ganj, already includes C3R, specialty lenses and transplants. Intacs are one tool for selected cones. We will not use rings to delay a graft that is already indicated, or skip C3R when the cone is still progressing.

I recently underwent Topography-guided PRK (Contoura) surgery here, and my experience was absolutely fantastic. I had a high cylindrical power (-3.25) and was honestly a bit nervous, but Dr. Neera agrawal and the entire staff made me feel completely at ease. They took the time to explain exactly why PRK was the safest and best option for me. The procedure was incredibly smooth, and my recovery is going exactly as they guided. The hospital is exceptionally clean, the staff is very cooperative, and the technology is top-notch. If you are considering getting rid of your glasses, I highly recommend dr. Neera and this hospital. Thank you for giving me a glass-free life!
