A 60-year-old female with pseudophakic bullous keratopathy presented with pain and defective vision in OD for 3 months. She also gave a history of cataract surgery performed in OD 3 years back. Slit-lamp anterior segment examination revealed conjunctival congestion, epithelial bullae, diffuse stromal edema with corneal decompensation, and the rest of the details were hazy. Fundoscopy was hazy in OD. Anterior and posterior segment examination in left eye (OS) was normal. Her visual acuity was finger counting close to the face (FCF) OD and 20/20 in OS. Intraocular pressure by noncontact tonometry was an error in OD and 14 mmHg OS. In view of severe pain, bullae rupture was done and a Bandage contact lens (BCL) was applied. She was advised topical 0.5% moxifloxacin six times/day, 0.5% carboxymethyl cellulose six times/day and 1% homatropine two times/day eye drop under close follow-up. The patient was lost to follow-up for 2 months. Later she presented with pigmented mid-stromal fungal infiltrate of 4 mm × 4 mm with another 3 mm × 3 mm central pigmented patch under the BCL [Figure 1]a. Scraping was performed which revealed pigmented fungal hyphae on 10% KOH and culture on potato dextrose agar and lactophenol cotton blue mount revealed Alternaria spp. Pigmented fungal infiltrate under BCL [Figure 1]b is a very rare occurrence. After the culture results, the patient was treated with topical 5% natamycin and 1% itraconazole hourly, 0.5% moxifloxacin six times, 1% homatropine two times, and advised follow-up after 5 days.

| Discussion|| |
The fungal entry in the lens matrix is promoted by manufacturing defects of the lens, structural damage, repetitive removal, and application of the lens. This is a very rare presentation of dematiaceous fungi Alternaria in BCL. This case highlights the importance of contact lens care and handling, patient education, counseling, and regular follow-up post-BCL application., Prompt microbiological evaluation and meticulous management can prevent irreversible blinding sequelae in these scenarios.
