What causes Keratoconus?
Keratoconus is a condition which causes the cornea to become cone shaped as the result of a bulging weak spot. This bulge creates distortion in your vision, so those with the condition have difficulty focussing. Keratoconus is more likely to progress in those who develop the condition at an early age. It involves both eyes, but can affect one eye more than the other due to development of the condition at different rates. Eye rubbings worsens the condition and it is often associated with allergies, asthma and eczema.

There is no single cause for the condition Keratoconus and numerous factors have been implicated and the causes are “multifactorial”. Many with Keratoconus are concerned that they may pass on the condition to their children. Whilst Keratoconus can be inherited, a more common association is allergies and patients often have hay fever, asthma and eczema. Hay fever causes itchiness and eye rubbing aggravates the condition.
Although Keratoconus can occur earlier, more often its onset is in puberty. The condition progresses and then in the late 30s and 40s slows down and stops. Keratoconus has also been observed in contact lens wearers and it is not clear if contact lenses can contribute to the condition or is it because Keratoconus results in shortsightedness and patients use contact lenses for correction. Overall in Keratoconus, the cornea is more elastic than normal and has a tendency to change shape and become steep. Pressure on the cornea can make the weakest area bulge more and is the reason why eye rubbing is strongly discouraged.
Treating Keratoconus
1
Spectacles/Glasses
In the early stages when the cornea is not too abnormally shaped, glasses can help correct vision. Often glasses need to be changed frequently and this is the tip-off that the patient may have Keratoconus, especially if there is a progressive increase in astigmatism.
2
Hard Contact Lenses
Hard or rigid contact lenses and Scleral lenses are useful for improving vision when glasses no longer work. A hard contact lens evens out the corneal irregularities and permits good vision. In some cases contact lenses can become difficult to fit or tolerate at which point surgical options may need to be considered.
3
CXL – Corneal Collagen Cross linking with Riboflavin
This procedure is used to strengthen the cornea and has been used at Centre for Sight since 2005. Strengthening the cornea and reducing its elasticity can stop progression and in some case even cause flattening and an improvement in corneal shape. Find out more about CXL by clicking here.
4
Keranatural CAIRS
The use of corneal tissue to alter the shape of the cornea is a recent advance in the treatment of keratoconus. Results of this procedure have been outstanding and now the preferred option for Intracorneal ring segments. Plastic inserts ( Intacs and Ferrara – right) have been used with great success in the past, however the use of cornea avoids halos and light reflection. Learn more about Keranatural CAIRS here.
5
Intracorneal Rings (Intacs and Ferrara Rings)
These are rings that are inserted into the cornea using a femtosecond laser to create channels. The rings alter the shape of the cornea regularising the shape decreasing astigmatism as well as reducing shortsightedness / myopia by flattening the central cornea. For those who have become intolerant to contact lenses and where the cone is not scarred or not excessively advanced, intracorneal rings can help improve vision with glasses or even allow contact lenses to be fitted. For those who obtain improved vision with glasses, Toric Implantable Contact lenses can be considered to eliminate the need for optical aids altogether. Learn more about Intracorneal Rings here.
6
Toric Implantable Contact Lenses
For those who are able to obtain good vision with glasses and have Keratoconus that has stopped progressing, Toric Implantable Contact Lenses can reduce the need for glasses and in many cases eliminate the need for optical aids. Implanting Toric ICLs in patients with Keraotoconus is less predictable than regular myopic astigmatis. You can learn more about the Toric ICL here.
7
Corneal Transplants
In very advanced stages affecting approximately 15% of Keratoconus patients a corneal transplant may be needed. A partial thickness or Deep Anterior Lamellar (DALK) is the preferred option. A full thickness or Penetrating keratoplasty (PK) is an option that has been used in the past and in countries outside the USA is becoming less common. Precise lasers for use in laser vision correction have been adapted to enable grafting procedures. This technique improves corneal graft apposition and mechanical strength. The option of a Femtosecond Laser Deep Anterior Lamellar Keratoplasty has been developed and pioneered by Centre for Sight surgeons. The technique displayed in a video created by Centre for Sight was the recipient of a video award at the American Society of Cataract and Refractive Surgeons, San Francisco, 2013.

Patient Success Stories
Absolutely exceptional
From my initial consultation on 30th September to my follow up appointment on 28th October having had cataract surgery and multi focal lenses inserted in both eyes I have received exceptional care, kindness and professionalism. The entire procedure has far exceeded my expectations and absolutely everyone in the team have been incredible. I was made to feel special every step of the way which was painless and totally comfortable. I can wholeheartedly recommend Centre For Sight at East Grinstead.

A friend recommended Centre for Sight.
I had two cataracts removed and am delighted with the outcome. All the staff were highly professional, took meticulous care and their work was exemplary. Particular thanks to Adora who was so kind and reassuring throughout. I highly recommend Centre for Sight for anyone considering treatment.
Eventually I went to Specsavers in Egham for some mild driving glasses and the optician looked into my eyes and said that he had never seen such a good job on lens replacements. Best he had ever seen.

As I write this – five days after the first eye was done, I can see clearly! I’m hoping for further improvement as the coming weeks pass.
Overall, the team are extremely professional, all led under the leadership and expertise of Mr Daya. He only has one objective – to make your vision better. And that he has achieved.
Thank you so much.
Best wishes,

Cataract Surgery Performed Expertly.
Cataract surgery performed expertly by Mr Sheraz M Daya on both eyes. Trifocal lense implants in one procedure and I am now glasses free with better than perfect vision. From start to finish the attention to detail, friendly professionalism and expertise of everyone at Centre For Sight was outstanding.
I cannot praise Mr Daya and his team too highly, and would recommend the procedure to anyone. It truly can be life changing.
Many thanks to everyone at Centre For Sight and in particular Mr Daya.
