H25-H28: Disorders of lens

Disorders of the lens, as covered under the ICD-10 codes H25-H28, refer to a group of conditions that primarily affect the lens of the eye - a crystal-clear, flexible structure that sits behind the iris (the colored part of the eye). These disorders typically lead to problems with vision and their severity can range from mild to severe, depending on the specific disorder. Commonly reported symptoms across these disorders include blurred or distorted vision, trouble seeing at night, sensitivity to light, or seeing halos around lights. Some of these conditions, such as cataracts, can develop as a part of the aging process. Other disorders might occur due to injury, congenital defects, or as a complication from other diseases like diabetes. Generally, these lens disorders progress over time, gradually affecting the individual's vision as the lens becomes less transparent or its shape changes.
