A cataract is a cloudy area in the lens of the eye that leads to a decrease in vision of the eye. [1] [7] Cataracts often develop slowly and can affect one or both eyes. [1] Symptoms may include faded colours, blurry or double vision, halos around light, trouble with bright lights, and difficulty seeing at night. [1]
The duration and recurrence of symptoms depend on the underlying cause and the individual’s age or stage of life. Cyanopsia is most commonly reported in older adults after cataract surgery, where symptoms typically subside within a few days to weeks as the eyes adapt to the synthetic lens.

A-scan ultrasound biometry, commonly referred to as an A-scan (short for Amplitude scan), uses an ultrasound instrument for diagnostic testing. [1] A-scan biometry measures the axial length (AL) of the eye prior to cataract surgery in order to assess the refractive power of the intraocular lens that will be implanted.
