At Tygervalley Eye Laser Clinic, we have taken advantage of technological developments and advancements in the field of ocular condition treatment to bring our patients a new treatment for Keratoconus. This condition is typically diagnosed during adolescence and usually becomes most severe  between the ages of 20 and 40.

Keratoconus is a degenerative condition that occurs when the cornea, sometimes also referred to as the kerato, undergoes a thinning of collagen fibres and membranes that eventually deform into an irregular cone shape. The deforming of the cornea creates an irregular surface of the eye which results in a distorted visual image in the brain. Keratoconus is often genetic, and research has found that eye rubbing can contribute to its occurrence.

The disease is progressive, with most of the oxidative and mechanical damage increasing between the ages of 12 and 35. Spectacles cannot correct the vision of patients with this condition and hard contact lenses are often poorly tolerated, with little improvement in vision. At the Tygervalley Eye Laser Clinic, we can help you manage this condition effectively.










We use a Femtosecond Intralase laser that in our treatment of keratoconus. The laser is used to create intra-corneal channels for Ferrara rings placement. Ferrara rings act to flatten the cornea, giving it a more symmetrical and spherical shape. Prior to the introduction of the Intralase Femtosecond laser technology, manual techniques were used to create channels for the placement of Ferrara rings. This procedure often led to a number of complications due to inaccuracies.

The use of the Femtosecond laser allows the surgeon to  create extremely accurate channels and, thus, reduces the risk of inflammation or infection. This type of laser is able to create a reproducible tunnel at 75% of the thinnest corneal thickness.


  • Process is reversible
  • The ring segments can be adjusted to correct vision further
  • Rings are biocompatible, meaning zero rejection
  • High satisfaction rate
  • Delay or stabilisation of cone progression
  • No minimum age for surgery
  • Compatible with other procedures
  • Zero interference with corneal transplants
