CRYSTALLINE LENS

The crystalline lens is a clear, flexible structure behind the iris and pupil in the eye. It plays a crucial role in focusing light onto the retina, enabling clear vision.

Key functions:

  1. Focusing light: The lens changes shape to focus light on the retina, allowing us to see objects clearly at varying distances.
  2. Accommodation: The lens adjusts its shape to focus on near or far objects, a process controlled by the ciliary muscles.

Characteristics:

  1. Transparency: The lens is clear, allowing light to pass through.
  2. Flexibility: The lens changes shape to focus light.
  3. Protein composition: The lens is made up of proteins and water.

Common issues:

  1. Cataracts: Clouding of the lens, affecting vision.
  2. Presbyopia: Age-related loss of near vision due to reduced lens flexibility.

The crystalline lens is a vital part of the eye’s anatomy, and its proper function is essential for clear vision.

APHAKIA

This simply means the absence of crystalline lens of the eye,

Loss of crystalline lens can be as a result of surgery, cataract, penetrating injury or congenital.

People with APHAKIA find it difficult to focus on objects and they also experience very high degree of long sightedness and deep anterior chamber angle.

The crystalline is responsible for accomodations and it contribute to one third of the refractive power of the eye. So without this crystalline in place behind the iris, patients will find it difficult to focus on objects and will experience serious degree of far sightedness.
