Thinning corneas and extreme astigmatism

What is keratoconus, and how can we address it?

Keratoconus is a severe form of astigmatism. It is a degenerative non-inflammatory disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than its normal gradual curve.

What are the symptoms of Keratoconus?

Keratoconus can cause substantial distortion of vision, with multiple images, streaking and sensitivity to light all often reported by the patient. If both eyes are affected, the deterioration in vision can affect the patient's ability to drive a car or read normal print.

How is keratoconus diagnosed?

Keratoconus is typically diagnosed in the patient's teenage years and attains its most severe state in the twenties and thirties. One of the more common factors associated with keratoconus is eye rubbing.

Once patients reach their forties the cornea begins to stiffen up naturally and this slows or even stops the progression of the keratoconus.

This observation has led to the development of a treatment called collagen cross-linking. Riboflavin and ultraviolet light are used to stiffen the lens by three hundred percent.

What is the keratoconus treatment?

In most cases, corrective lenses are effective enough to allow the patient to continue to drive legally and likewise function normally.

Further progression of the disease may require treatment (such as Cross-linking CR-3) or surgery including intracorneal or intrastromal rings or a corneal transplant (deep anterior lamellar keratoplasty or penetrating keratoplasty).

Mr Ball is one of a handful of surgeons who is able to offer the full range of treatments for keratoconus.

My eyesight following the operation is brilliant and better than I thought possible, and this is all down to your excellent surgeon Mr James Ball and not to forget all the very dedicated people around him who make these operations possible.

Keith Garlick

Two of the best decisions I ever made in my life were firstly to have lens exchange and secondly to have Mr James Ball carry out my operation.

Patricia Walton

Within minutes I could tell there was a difference. But now, only a couple of months later, my sight is better than it was seven years ago! I can even read the really tiny print on the car sales ads! If you want that confidence you probably felt when you were younger, this is the ideal solution. Thanks to the treatment, I feel rejuvenated, independent and much younger!

John Hazelgreave

Many thanks for all your care and kindness. To me it appears a miracle that I can see so well. I feel very grateful. It is impossible to fully express my thanks.

Grace C.

May I offer grateful thanks for your expertise in operating on my eyes. It was intimated to me that you were the best, and from the results I am now enjoying, I am convinced that this is correct.

Jean D.

You are truly innovative. Thank you very much for curing the problems I have been having with my reading and near vision.

Sala M.

My work was becoming almost impossible. I had refractive lens exchange to both eyes with multifocal lens implants last July. I can now see better than 20/20 for distance and can read the tiniest print in newspapers - all without glasses! I have started reading for pleasure again, and I feel that my performance both at work and on the golf course has improved.
