Correcting Irregular Astigmatism
Irregular astigmatism refers to an abnormally shaped front of the eye, causing blurring of vision.
As head of corneal services at the Bristol Eye Hospital, Kieren has had years of experience treating complex corneal issues throughout the South West of England.
In his private practice, he can extend his treatments using advanced corneal scanning equipment and state-of-the-art excimer laser technology to complement his manual procedures.
Several issues and conditions can affect the cornea; please find details of the most common. If you are experiencing any other corneal complaints, please do not hesitate to contact us, and Kieren will be happy to help.

FAQ's Irregular Astigmatism
How do I know what the issue is with my cornea?
Some patients visit Mr Darcy further to a diagnosis from either an optometrist or another ophthalmologist. Kieren will conduct a thorough examination of your eyes, including detailed corneal scanning and magnified high definition images of the eyes. With detailed discussion about the history of your complaint and health he will aim to diagnose the condition and recommend a treatment pathway.
What treatments are available for corneal issues?
Treatment obviously varies depending on the diagnosis of the condition and sometimes a pharmacological route is all that is required. Other common treatments include:
Photo-therapeutic keratectomy (PTK) which is performed using an excimer to smoothly remove the top layer of the cornea to promote healthy regrowth in a more regularised pattern.
Topographically guided photo-therapeutic keratectomy (PTK), that can precisely treat irregular areas or scars on the cornea, to eliminate or limit visual distortion.
Superficial keratectomy – this is a manual debridement procedure and better suited than laser for the removal of the epithelium, the front surface of the cornea, for various conditions.
Corneal transplant – for some severe cornea conditions a corneal transplant may be recommended. You can find out more about transplant treatments here.
