Corneal Implants

This treatment is used to reshape irregular corneas making contact lenses more comfortable and can partially improve vision.

Corneal Implants

Corneal implants like INTACS and Kerarings are used to treat sufferers of Keratoconus whose disease has stabilised naturally or with Collagen Cross Linking. Corneal implants are intra-stromal corneal inserts consisting of two clear crescent-shaped pieces of a bio-compatible material. The inserts reshape the cornea and correct the visual distortion caused by the Keratoconus. The implants inserted into the cornea flatten the surface and help improve refractive errors.

Corneal implants are primarily used to improve the shape of an irregular cornea. They can partially correct vision meaning glasses or contact lenses are still required after treatment. However, this treatment vastly improves a patient’s best corrected vision. The treatment is designed to make wearing contact lens more comfortable, it is completely reversible and exchangeable if needed.

Dr Pillai is a corneal specialist and has been performing Corneal Implant surgeries at Advanced Vision Care since 2010.

The treatment takes approximately 30 minutes for both eyes. The process is as follows:

  • Anaesthetic drops are used to numb the eye.
  • Eye lid guard used to prevent blinking.
  • A micro incision is made in the cornea using the Intralase laser (blade free).
  • The Intralase laser is used to separate the corneal layers to form a tunnel in stroma.
  • The corneal implants are inserted into the tunnels created by the laser on each side of the pupil.
  • Our specialist nurse will go through the precautions and medications that are needed to aid your recovery.
  • Your first post-operative appointment will take place 4 to 5 days after your treatment.


  • They are biocompatible and there is no risk of rejection.
  • Reversible and exchangeable.
  • Corneal implants cannot be felt.
  • Better corrected vision and improved tolerance to contact lenses.
  • FDA approved in 2004

On the day of treatment you will be provided with an eye cover for the treated eye, anti-inflammatory, antibiotic and hydrating drops. You will be advised when to take the drops. At your first post-operative check 4 to 5 days after keratoconus surgery of this type, your surgeon will examine the treated eye and assess the rate of healing.

The recovery period can take up to a week; some discomfort and light sensitivity can be experienced for a couple of days after treatment. You are likely to suffer from dry eyes whilst your cornea heals, this is completely normal.

Visual fluctuations can last between 3 to 6 months, once the prescription stabilises new glasses and contact lenses can be fitted. You are required to attend regular post-operative appointments throughout the year. These check-ups can be conducted at our AVC clinic or at one of our optometrist network partners from 3 months onwards.
