Home > Your Eyes > Keratoconus


Keratoconus is an inherited condition where the cornea is abnormally elastic and over a period of time bulges forward causing distorted and blurred vision. Eye rubbing is a contributing factor to its progression.

The treatment of keratoconus depends on its severity.


Mild Keratoconus can often be corrected with glasses or contact lenses.

A procedure called ‘Collagen Cross Linking’ can be performed to stabilize and help prevent further progression of Keratoconus. This can be performed at any time however mild Keratoconus is ideal for the treatment as it allows the individual to maintain their current level of vision. Dr Genge is an authority on Collagen Cross Linking and performs it often.

Moderate Keratoconus may require reshaping of the cornea using tiny clear crescents of plastic called Kerarings. A laser painlessly creates a channel within the cornea and the Keraring is inserted in a procedure that takes 15 minutes and is performed in rooms. Dr Genge is amongst the most experienced surgeons in this technique of Keratoconus treatment in Sydney and all of Australia.

Once the corneal shape is optimised, an Intraocular Contact Lens (ICL) can be utilised to achieve independence from spectacles and eyeglasses.

Advanced Keratoconus requires a corneal transplant to achieve good visual quality. Dr Genge performs deep, partial thickness corneal transplant techniques (Deep AnteriorLamellar Keratoplasty: DALK) to avoid corneal transplant rejection found in standard corneal grafts. He is one of a handful of Australian surgeons experienced in the technique and has a subspecialty fellowship from Moorfields Eye Hospital in Corneal Transplant Surgery.

Fuchs Endothelial Dystrophy is an inherited corneal condition where the endothelium, a single layer of cells that line the inside of the cornea, is deficient. The role of the endothelium is to pump water out of the cornea. When, as the individual ages, the cells become too few to perform this function, the cornea becomes water-logged and cloudy.

The individual will at this time require replacement of these cells with a corneal transplant technique. There are two techniques for correcting this condition, Dr Genge is proficient in both.

Full Thickness Corneal Transplantation:

A central button of the cornea is excised and a size-matched button from a donor cornea is sewn in. Dr Genge tends to reserve this technique for patients that are unsuitable for an Endothelial Transplant.

Endothelial Transplantation

A partial thickness disk of donor tissue with the healthy endothelium on the inside is created and slipped into the eye where it is pushed into position with an air bubble and becomes adherent.

This technique has the advantages of a rapid recovery of vision and minimal induced astigmatism as well as leaving the eye tectonically stronger. This is a highly specialized technique and Dr Genge is one of a few surgeons in NSW who can perform it.
