H25-H28: Disorders of lens

H26: Other cataract

Cataracts falling under the H26 category in the ICD-10 WHO 2016 classification, also known as 'Other Cataract,' represent a group of specific types of cataracts not classified elsewhere. A cataract is a condition where the lens of the eye becomes clouded, disrupting the vision. The types in this group commonly result from various factors like exposure to certain types of radiation, the use of certain medications, specific metabolic disorders, or diseases like diabetes. The primary symptom of these cataracts is blurred or dimmed vision, often with an increase in glare or light sensitivity. Other symptoms may include difficulty with night vision, seeing 'halos' around lights, or experiencing changes in the way colors are perceived. The condition tends to progress slowly over time, gradually impairing the loss of visual acuity and limiting the field of vision. The conditions affect the ocular system, specifically the lens of the eye.
