Collagen Cross Linking is the only treatment available that halts the progression of Keratoconus and partially reverses the corneal steepening caused by the disease. The first ever patient was successfully treated in 1998 and at AVC we have been performing Collagen Cross Linking treatment since 2007. We offer epithelium-off treatment, this is when a corneal flap is created in the thin outer layer (epithelium) of the cornea which allows the liquid Riboflavin (Vitamin B12) to more easily penetrate the corneal tissue whilst being exposed to UV light. This non invasive procedure eliminates the need for a corneal graft and also can correct some of the patients prescription.
The progression of Keratoconus is halted through the process of photopolymerisation which is caused by the addition of Riboflavin under UV light, this leads to oxygen radicals enabling for the development of strong collagen bonds.
This technique strengthens the chemical bonds in the cornea which increases the thickness and stabilises the cornea, consequently stopping the progression of the disease. Treatment is only required once to cause a permanent change.
To be suitable for Collagen Cross Linking, your Keratoconus must be progressive but not too advanced that a corneal graft is required and you must be over the age of 18. Suitability for treatment will be determined by your surgeon after comprehensive testing at your consultation.
Mr Pillai is a corneal specialist and has been performing Collagen Cross Linking treatment at Advanced Vision Care since 2007.
Each eye is treated individually with a gap of a week. This corneal Keratoconus treatment is non-invasive and takes approximately 60 minutes per eye.
On the day that you will receive this form of Keratoconus treatment at our UK clinic, 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 the first post-operative check 4 to 5 days after treatment our surgeon will examine the treated eye and remove the protective lens.
The recovery period can take up to a week and some discomfort may be experienced for 2 to 3 days after treatment. Patients will suffer from dry eyes whilst the cornea heals. This is completely normal and is part of the natural healing process. Visual fluctuations can last between 1 to 3 months: once the prescription stabilises new glasses and contact lenses can be fitted.
However, small fluctuations in vision can still occur up to six months after treatment. Patients are required to attend regular post-operative checks throughout the year. These can be conducted at our AVC Keratoconus 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 your consultation. Patients can usually start driving once the prescription has stabilised and they have new glasses or contact lenses. If Kerasoft lenses are used the amount of time can be reduced to 5 to 10 days.
We are leading providers in treatments for Keratoconus and offer complete visual rehabilitation for sufferers of the disease. We provide bespoke treatments that are tailormade to correct the visual impairment caused by Keratoconus, these treatments can halt the progression, make contact lens wear more comfortable and there are also procedures that provide total vision correction.
AVC provide all patients with the best care and results, constantly surpassing expectations. For the convenience of our patients, all our bespoke treatments are under one roof and everyone has access to the largest independent optometrist network in the country, meaning you can enjoy incredible aftercare at a more convenient location.
