Why referral may matter
Keratoconus management can involve specialist corneal assessment. The right pathway depends on corneal findings, age, progression and vision needs.
Contact lens questions
Some corneal conditions may require specialist contact lens options. iFocus can advise whether further corneal or contact lens referral is appropriate.
Common questions
Can keratoconus make glasses less clear?
Yes. Irregular corneal shape can make vision distorted or less clear with ordinary glasses.
Does iFocus perform corneal surgery?
No. If specialist corneal care is needed, the optometrist can advise referral pathways.
Should changing astigmatism be checked?
Yes. Frequent prescription or astigmatism changes should be assessed.
