Until recently, patients have worn contact lenses unless they needed a cornea transplant – there was no choice and no way of stopping keratoconus from getting worse. Dr Khalil is offering all the revolutionary new approaches in a tailored manner giving each individual of his patients with keratoconus the best .treatment suitable for his individual case.
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.
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. It sis carried out with some of the best equipment available today.
Laser may now be used to treat keratoconus by using a cornea topographer to guide the laser, or what is called topography-guided treatment. This is an important development.
These are small pieces of plastic inserted into a channel created in the cornea to stretch it and bring it back to near its original configuration. They can’t be felt and require no maintenance. They are normally invisible except on close inspection when they look like a contact lens on the eye
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, laser or rings implantation have been done to stabilise the cornea and normalise its shape as much as possible
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.
