Treatment of Keratoconus
What is the best treatment for keratoconus?
In recent years, there have come several new modalities for the treatment of keratoconus; like collagen cross-linking, the possibility of lens implantation, femtosecond ring implantation, let alone the new techniques of corneal grafting or keratoplsty together with classical options for the treamtnet of keratoconus like the hard or rigid gas permeable (RGP) contact lenses. This is because keratoconus is a varied disease with a wide spectrum of presentation.
Dr Ahmad Khalil has witnessed several of these new techniques in the making , and was part of conferences which witnessed the birth of these new techniques for the treatment of keratoconus. Dr Khalil explains that no single technique is considered the universal best option for the treatment of keratoconus. Each case of keratoconus has to be treated individually with what is best suited. Some cases benifit most from collagen crosslinking and RGP contact lenses, while others beniofit more from femtosecond ring implantation or keratoplasty.
Following a comprehensiveconsultation at Dr Ahmad Khalil Eye Clinic in Cairo, Egypt, he will be able to determine your best option for treatment and offer it for you.
Collagen cross linking is an important new treatment that stops keratoconus from getting worse. Cross linking increases the strength of the collagen in keratoconic corneas by 3–4 times. Dr Ahmad Khalil carries out collagen cross linking wieh some of the best and updated equipment available today.
ICL implantation can be an effective treatment in selected cases of keratoconus after cornea shape is normalised
These are lenses put over the normally present lenses. They work together with the eye’s natural lens which is not removed. In a normal cornea it is capable of correcting even the most severe short sight and astigmatism. In keratoconus it is most effective after collagen cross linking, or rings implantation have been done to stabilise the cornea and normalise its shape as much as possible
Contact lenses do not change the keratoconus, but cover the protrusion on the cornea so neutralising it. Normal vision is restored to all except advanced cases. Lifelong wear is necessary.

A long-established treatment for the most severe cases
The centre of the patient’s own cornea is completely removed and replaced by another corneal transplant. The transplant is sutured in place of the conical cornea. This is the longest-established treatment for severe keratoconus.
Laser treatment can be used to treat keratoconus in some rare occcasions by using a cornea topographer to guide the laser, or what is called topography-guided treatment. This is an important development, but Dr Ahmad Khalil reserves it to very rare cases, where the cornea is stable, with a minimal refractive error untreatable by other means.
