H25-H28: Disorders of lens

H27: Other disorders of lens

Other disorders of the lens, classified under the H27 range according to ICD-10 WHO 2016 classification, encompass a variety of issues relating to the eye's lens. The lens is a vital part of the eye, helping to focus the light onto the retina, thus enabling vision. Any disorders related to the lens can potentially disrupt this delicate process impacting vision or causing blindness. Conditions under the H27 range could include a dislocated lens, congenital lens malformations, or other specific lens disorders like cataracts not classified elsewhere. Common symptoms across these conditions may include blurred vision, vision loss, changes in color perception, and glare or halos around lights. These disorders can occur due to various reasons such as aging, trauma, certain diseases like diabetes, exposure to ultraviolet light, and hereditary factors. While the progression of lens disorders can vary widely, they generally worsen over time and can lead to significant vision impairment.
