# Aphakia

Aphakia is the absence of the natural crystalline lens from the eye. It most often follows cataract extraction without implantation of an intraocular lens, or lens loss after trauma.

## Visual consequences

Without the lens, the eye loses a major part of its focusing power.

- High hyperopia and reduced ability to focus at different distances
- Image distortion and aniseikonia if only one eye is aphakic
- Increased light sensitivity and chromatic aberration
- Risk of retinal detachment and glaucoma in some causes

## Correction and management

Several options restore focus and comfort.

- Intraocular lens implantation primary or secondary when possible
- High-plus glasses or contact lenses in eyes without an implant
- Regular monitoring for retinal or pressure-related complications
- Visual rehabilitation and amblyopia management in children
