The explanted inlay was discarded by the facility and is not available for evaluation.The device history record (dhr) review of the manufacturing lot for this device was performed and there were no discrepancies or unusual findings related to the reported issue.Epithelial defect, recurrent corneal erosion, decreased bcdva, and inlay removal are listed in the device labeling as known potential risks.(b)(4).

The patient underwent uneventful implantation of the raindrop corneal inlay in the right eye on (b)(6) 2016.Postoperatively the patient developed a persistent non-healing epithelial defect in the operative eye, which was initially located at the superior flap edge and later involved the entire flap surface, approximately 5 mm round.At first onset 2 weeks postoperatively, the patient reported experiencing eye redness, photophobia, and blurred vision with periods of exacerbation and improvement.One month postoperatively the patient was diagnosed with epithelial basement membrane dystrophy (ebmd) in both eyes and the patient disclosed possible eye rubbing.On (b)(6) 2017, the patient presented with recurrent corneal erosion and bcdva decreased to 20/400; the inlay was subsequently explanted on (b)(6) 2017.On april 6, 2017, the patient presented with a neurotropic corneal ulcer and central corneal haze (grade 1-2+); the cornea was cultured and the culture report showed no bacterial or fungal growth.According to the surgeon, the corneal haze was not related to the corneal inlay with onset occurring only after inlay removal.At last examination on (b)(6) 2017, the patient was not improving and the prognosis is guarded.The epithelium has not healed, vision remains 20/400 - hand motion, and a corneal transplant is likely needed.In the surgeon's opinion, the likely causes/contributing factors include subclinical ebmd and the gutter surrounding the corneal flap did not re-epithelialize in an expected manner.
