Corneal Implants – INTACS & Kerarings

View Video

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 corneal implantsand 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 improve a patient’s best corrected vision. The treatment is designed to make wearing contact lens more comfortable and is completely reversible and exchangeable if needed.

  • AVC has been performing Corneal Implants since 2010.
  • They are bio-compatible and there is no risk of rejection.
  • Reversible and exchangeable.
  • Corneal implants cannot be felt.
  • AVC’s lead surgeon and retinal specialist with over 25 year’s experience.
  • Better corrected vision and improved tolerance to contact lenses.
  • FDA approved in 2004.

Corneal Implants: Treatment Process

corneal implants treatment processThe 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.

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 treatment, 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.

After treatment, you can return to normal life. However, there are restrictions on certain activities and these will be discussed at the consultation. You can usually start driving once your prescription has stabilised and you have obtained new glasses or contact lenses. If Kerasoft lenses are used the amount of time can be reduced to 5 to 10 days.
