What is keratoconus?
Keratoconus is a condition in which the cornea becomes progressively steeper and more irregular, potentially causing blur, glare and changing prescriptions. Assessment relies on examination, corneal imaging and comparison over time.
What does the assessment include?
Assessment commonly includes symptom history, refraction, ocular-surface evaluation, corneal imaging and review of previous reports. Details vary according to age, previous procedures and lens use.
When should corneal imaging be repeated?
Timing depends on age, disease stage, visual change and previous results. Rapid prescription or visual change, or frequent eye rubbing, warrants prompt assessment.
Possible visual correction
Options may include spectacles in early stages and RGP, hybrid or scleral lenses for irregular corneas. Selection follows assessment of vision, comfort and ocular-surface health, and does not replace an ophthalmologist’s decision regarding surgical treatment.
What to bring to your appointment
- Previous corneal images and reports, if available
- Details of prior corneal procedures or cross-linking
- Current spectacles and contact lenses
- Lens-removal timing before the visit as advised by the centre
