We fit Contact Lenses for Keratoconus in Sydney and Parramatta
At Westmead Eyes Optometrists we are trained to diagnose keratoconus, monitor its progression and fit contact lenses for keratoconus.
What is Keratoconus?
Keratoconus is an eye condition in which the cornea (the front surface of the eye) thins and weakens, causing it to change shape. The thinning of the surface causes the cornea to protrude forward, developing a ‘cone’ shape. This distorts light entering the eye and results in blurry vision and light sensitivity. As the disease advances, other complications can occur such as scarring or hydrops. Extreme cases may result in the need of a corneal transplant.
Typically, we diagnose keratoconus in patients aged between 16-30. We have the tools to detect and monitor the progression of keratoconus using a corneal topographer. This allows us to map out track the changes of the shape of the cornea over time. If progression is rapid we may refer for treatment with an eye specialist with methods such as corneal collagen cross-linking (CXL) , Intacs corneal ring segment implants, and if all other treatment options are unable to give a satisfactory visual outcome, a corneal transplant or graft surgery.
Contact Lens Fitting for Keratoconus
In cases of moderate to advanced keratoconus, patients often can no longer achieve clear vision with glasses. The solution is to be fit with specialised rigid contact lenses. These lenses act as a new surface and make the corneal shape more regular. Specialty contact lenses such as gas permeable lenses, hybrid lenses, and scleral lenses can be used to help achieve functional vision. Many patients achieve good vision for many years using custom contact lenses, without ever needing a corneal transplant.
I have Keratoconus – am I suitable for contact lenses?
If you have keratoconus and would like to talk to us about whether you require contact lenses and which contact lens type might suit you best, please don’t hesitate to contact us for an appointment or trial. We are experienced in this condition and can recommend treatment options specific to your case.
