Aphakia, left eye

This code signifies the absence of the natural crystalline lens in the left eye. This condition typically results from surgical removal of a cataract or severe trauma, leaving the eye without its primary focusing mechanism. Patients with aphakia require optical correction, such as spectacles, contact lenses, or an intraocular lens implant, to achieve functional vision.

Use this code when documentation explicitly states aphakia of the left eye. This is commonly seen post-cataract extraction without intraocular lens (IOL) implantation, or following traumatic expulsion/removal of the lens. The medical record should clearly indicate the absence of the lens in the specified eye.

• Always specify laterality; do not use unspecified codes if the documentation provides left or right eye.
• Distinguish from pseudophakia (presence of an artificial IOL), which has a different code.
• If aphakia is bilateral, use the appropriate bilateral code or codes for each eye.
