Name of the Condition

• Aphakia, right eye
• No lens in the right eye

Summary

Aphakia is a medical condition where the natural lens of the eye is absent. This absence can significantly affect vision, since the lens is responsible for focusing light onto the retina.

Causes

Aphakia may result from surgical removal of the lens due to cataracts, trauma to the eye, or it might be a congenital condition where a person is born without a lens.

Risk Factors

• Previous eye surgery for cataracts
• Eye trauma or injury
• Congenital defects present from birth

Symptoms

• Blurred vision in the affected eye
• Difficulties focusing on objects
• Increased sensitivity to light (photophobia)
• Possible distortion of vision

Diagnosis

Diagnosis is usually made through a comprehensive eye examination by an ophthalmologist, which may include:

• Visual acuity test
• Slit-lamp examination
• Retinal examination

Treatment Options

• Contact Lenses or Intraocular Lens (IOL): Special corrective lenses can be fitted to compensate for the absent natural lens.
• Glasses: High-power prescription glasses may be used to improve vision.
• Surgical Treatment: In some cases, inserting an artificial intraocular lens can restore focus.

Prognosis and Follow-Up

With proper treatment, many patients can achieve satisfactory vision. Regular exams are crucial to monitor the condition and adjust treatment as needed.

Complications

• Glaucoma
• Retinal detachment
• Further visual impairment if untreated

Lifestyle & Prevention

• Protect eyes from injury with appropriate eyewear.
• Regular eye check-ups, especially after cataract surgery, can help manage and monitor aphakia.

When to Seek Professional Help

Immediate medical attention should be sought if there is sudden loss of vision, signs of infection, or significant changes in vision.

Tips for Medical Coders

• Confirm the condition is specifically for the right eye (use correct laterality).
• Ensure differentiation between aphakia due to congenital reasons versus post-surgical causes.
• Double-check for any related procedures that might also need separate coding.
