Name of the Condition

• Displacement of intraocular lens, sequela
• Also referred to as dislocated IOL (intraocular lens) post-surgery residual effects

Summary

• This condition involves complications or lingering effects resulting from the displacement of an intraocular lens, typically following cataract surgery or lens replacement. It may require further medical attention to correct visual disturbances or discomfort.

Causes

• Surgical trauma, improper lens sizing, or weak capsular support following cataract or other ophthalmic surgeries can lead to the displacement of the intraocular lens.

Risk Factors

• Advanced age, previous eye trauma, conditions like pseudoexfoliation syndrome, or connective tissue disorders increase the risk of IOL displacement.

Symptoms

• Patients may experience blurred vision, double vision, glare, halos around lights, or noticeable shifts in their vision.

Diagnosis

• A comprehensive eye examination by an ophthalmologist including slit-lamp examination and imaging studies such as ultrasound biomicroscopy or optical coherence tomography (OCT).

Treatment Options

• Treatment may involve observation, repositioning of the lens through surgical intervention, or replacement of the lens. Surgical options may include suture fixation or scleral fixation of the lens.

Prognosis and Follow-Up

• With timely surgical intervention, the outlook is generally positive with restoration of vision. Regular follow-up is critical to monitor eye health and detect potential complications early.

Complications

• If untreated, the displaced lens can cause retinal detachment, increased intraocular pressure leading to glaucoma, or persistent visual disturbances.

Lifestyle & Prevention

• Regular eye exams to monitor eye health after surgery are key. Patients should avoid activities that may put excessive pressure on their eyes and follow their ophthalmologist’s advice to reduce displacement risk.

When to Seek Professional Help

• Immediate consultation is warranted if there is a sudden change in vision, increase in eye pain, or if visual symptoms like halos and glare significantly worsen.

Tips for Medical Coders

• Ensure accurate coding by verifying if the condition is a sequela (residual effect) using detailed patient medical history and records.
• Be cautious of coding errors such as confusing initial or acute displacement with sequela; confirm with supplemental documentation.
