Astigmatism describes an irregular corneal surface. It is steeper in one direction compared to another, like the back of a spoon. Like short or long sight, astigmatism describes the refractive error. It is not an eye disease or eye health problem, just an issue with how the eye focuses light.
In an eye with astigmatism, there are multiple focus points (either in front of the retina, behind it, or both). It cannot produce a clear image so patients with experience blurred vision at all distances.
Patients with astigmatism can be free from glasses and contact lenses with a procedure that suits their age:
- For those aged 20-45 years, LASIK is preferred, while an intracollamer lens (ICL) may suit those with a thin cornea or high prescription.
- For those people aged over 45 years, refractive lens exchange with premium intraocular lens implants corrects vision, removes the lens so a cataract will never develop and restores youthful vision for life.
- While those who are 60+ years of age, cataract surgery with premium intraocular lens implants corrects vision, removes the cataract and restores youthful vision for life.
