What are the next steps for an older adult with a history of cataracts who develops face swelling and rash after artificial intraocular lens replacement?

Management of Facial Swelling and Rash After Intraocular Lens Replacement

Immediately discontinue all topical eye drops and refer urgently to ophthalmology within 24 hours, as this presentation most likely represents allergic contact dermatitis from preservative-containing postoperative medications, which requires prompt allergen elimination and specialized periocular treatment. 1

Initial Assessment and Immediate Actions

Stop All Potential Allergens

• Discontinue all topical eye drops immediately, particularly preserved formulations of antibiotics (moxifloxacin), corticosteroids (prednisolone acetate), and NSAIDs, as preservatives are the most common cause of periocular allergic contact dermatitis in postoperative patients 1
• Review all cosmetics, skincare products, and any other substances applied near the eyes 1

Urgent Ophthalmology Referral Criteria

• All cases of facial swelling and rash after IOL surgery require ophthalmology evaluation within 24 hours to rule out serious complications including endophthalmitis, toxic anterior segment syndrome (TASS), or severe inflammatory reactions 2
• Immediate same-day referral is mandatory if accompanied by severe pain, vision loss, or signs of intraocular inflammation 2

Differential Diagnosis to Consider

Most Likely: Allergic Contact Dermatitis

• Preservative-containing postoperative eye drops are the primary culprit in periocular allergic reactions 1
• Presents as facial swelling, rash, and erythema around the eyes without necessarily affecting intraocular structures 1

Rule Out Serious Intraocular Complications

• TASS (Toxic Anterior Segment Syndrome): Sterile inflammation typically presenting within 12-48 hours post-surgery with anterior chamber reaction, but usually without facial rash 2
• Endophthalmitis: Infectious inflammation with pain, redness, decreased vision, and hypopyon; requires emergency treatment but typically does not present with facial rash 2
• Systemic hypersensitivity reaction: Rare but potentially serious; assess for respiratory symptoms, widespread urticaria, or hemodynamic instability 1

Initial Management While Awaiting Ophthalmology

Symptomatic Relief

• Apply preservative-free ocular lubricants to soothe the affected periocular area and provide immediate symptomatic relief 1
• Cool compresses may provide additional comfort, though this is not specifically addressed in guidelines 1

What NOT to Do

• Do not restart any preserved eye drops as they can worsen allergic contact dermatitis 1
• Do not apply topical corticosteroids to the skin without ophthalmology guidance, as periocular use requires specialized monitoring for glaucoma and cataracts 1
• Avoid self-prescribed antihistamines or other medications until the diagnosis is confirmed 1

Definitive Treatment (After Ophthalmology Evaluation)

Primary Treatment for Confirmed Contact Dermatitis

• Tacrolimus 0.1% ointment applied once daily to external eyelids and lid margins for 2-4 weeks has an 89% response rate and is the first-line treatment 1
• All patients using tacrolimus on lid margins require ophthalmology follow-up within 4 weeks 1

Transition to Preservative-Free Postoperative Regimen

• Switch to preservative-free antibiotic and corticosteroid formulations if continued postoperative treatment is needed 3
• Preservative-free prednisolone acetate 1% or loteprednol should replace preserved formulations 3
• Consider preservative-free ketorolac 0.45% for inflammation management 3

Adjunctive Treatments

• Topical antihistamine eye drops (olopatadine, ketotifen, or azelastine) for significant itching 1
• Warm compresses if meibomian gland dysfunction is present 1

Escalation for Non-Response

If No Improvement After 2-4 Weeks

• Discontinue tacrolimus and consider alternative treatments through ophthalmology 1
• Patch testing may be necessary to identify specific allergens 1
• Combination therapy with tacrolimus ointment and ciclosporin drops for treatment-resistant cases 1

When to Consider Systemic Corticosteroids

• Short-term systemic corticosteroids (such as methylprednisolone dose pack) may be considered for severe cases, but require close IOP monitoring due to risk of steroid-induced glaucoma 3
• This should only be initiated by ophthalmology after ruling out infectious causes 3

Critical Monitoring Points

Follow-Up Schedule

• Reassess at 4 weeks for patients on tacrolimus ointment 1
• If using any corticosteroids, monitor regularly for skin atrophy, glaucoma, and cataracts 1
• Standard post-cataract follow-up at Day 1, Weeks 1-2,1 month, 2 months, and 3-6 months should continue 3

Common Pitfalls to Avoid

• Continuing preserved eye drops in a patient with periocular dermatitis significantly worsens the condition and delays healing 1
• Assuming the rash is unrelated to postoperative medications when preservative allergy is extremely common in this setting 1
• Delaying ophthalmology referral risks missing serious intraocular complications that may present with periocular inflammation 2
• Using topical corticosteroids on periocular skin without ophthalmology supervision can lead to skin atrophy, glaucoma, and cataracts 1
