Keratoconus FAQs: Understanding the Condition and Treatment Options
What is keratoconus?
Keratoconus is a progressive eye condition where the cornea becomes thinner and bulges forwards into a cone-like shape, which can affect how light enters the eye and make vision less clear. At Centre for Sight, keratoconus is treated as a condition that needs careful assessment because it can affect each patient differently.
What symptoms can keratoconus cause?
Common symptoms include blurred or distorted vision, glare, light sensitivity, ghosting and increasing difficulty seeing clearly at night. Some people also notice frequent prescription changes, which is why specialist corneal assessment can be important if your vision seems to be worsening.
Does keratoconus always get worse over time?
Keratoconus can progress, but the speed and severity vary from person to person, so it is important not to assume every case follows the same pattern. Early diagnosis and regular monitoring can help identify whether the condition is stable or whether treatment such as corneal collagen cross-linking may be needed to help halt progression.
Can glasses or contact lenses help with keratoconus?
In earlier stages, glasses may improve vision, while in more established keratoconus, specialist hard or scleral contact lenses are often used to achieve clearer sight. These options do not cure the condition, but they can play an important role in managing visual symptoms before or alongside other treatment.
What is corneal collagen cross-linking?
Corneal collagen cross-linking, often called CXL, is a minimally invasive treatment that uses riboflavin drops and ultraviolet light to strengthen the cornea. It is commonly considered when keratoconus is progressing, with the aim of helping to stabilise the cornea and protect long-term vision.
Are there treatments beyond cross-linking?
Yes, depending on the shape of the cornea and the stage of the condition, treatment may also include intracorneal ring segments such as Intacs or Ferrara Rings, or CAIRS using donor corneal tissue. Centre for Sight offers these more advanced options as part of a personalised treatment plan rather than a one-size-fits-all pathway.
When is a corneal transplant needed for keratoconus?
A corneal transplant is usually reserved for more advanced cases where other approaches are no longer enough to provide useful vision or support corneal health. Centre for Sight offers specialist transplant procedures including DALK, femtosecond laser-assisted DALK and penetrating keratoplasty where clinically appropriate.
How is keratoconus diagnosed?
Diagnosis starts with a detailed consultation, full eye examination and corneal imaging so our specialist team can understand the shape of the cornea and how the condition is affecting your vision. This consultant-led approach helps determine whether you need monitoring, visual correction or a specific treatment.
Is keratoconus treatment the same for everyone?
No, keratoconus treatment should be tailored to the individual because symptoms, progression and corneal changes are not the same in every eye. Centre for Sight uses personalised planning to match care to your diagnosis, vision needs and longer-term sight goals.
When should I book a consultation about keratoconus?
It is sensible to book a consultation if you have recently been diagnosed, your prescription keeps changing, or you are noticing symptoms such as distortion, glare or worsening night vision. Centre for Sight sees patients in London, Surrey and Sussex, offering specialist corneal advice for people who want clarity on their options and next steps.
