SHAH ALAM, Nov 4 — For most people, worsening eyesight means getting a stronger pair of glasses. But when spectacle prescriptions keep changing and vision remains blurred even with new lenses, the problem may lie deeper than short-sightedness or astigmatism.

It could be keratoconus, a progressive condition in which the cornea – the transparent surface at the front of the eye – gradually thins and bulges into a cone, distorting the way light enters the eye and impairing vision.

“If you find yourself visiting the optical shop frequently and still cannot see clearly enough with your glasses, please see your eye doctor,” Dr Ainur Rahman Anuar Masduki, consultant ophthalmologist and corneal surgeon at Ara Damansara Medical Centre (ADMC), told CodeBlue in an interview.
