The explanted corneal inlay has not been returned to the manufacturer at this time.The site is being contacted to determine whether it is still available for analysis.The device history record review of the manufacturing lot was performed and there were no discrepancies or unusual findings related to the reported issue.Dry eye, epithelial defect, vision loss, and infection 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) 2017.On (b)(6) 2017, the patient presented with a corneal ulcer/possible infection and the patient's best corrected distance visual acuity had decreased from 20/20 (preoperatively) to 20/70.The size of the ulcer was approximately 5 x 5 mm, located at the 6-8 o'clock position.The eye was cultured at this visit and the culture report revealed a few gram negative rods, possible pseudomonas.It was also noted that the patient had punctal occlusion of lower and upper lids.A second culture report was unchanged and a 3rd culture showed very few possible staph species.A 4th culture report showed a few staph epi and a 5th culture was positive for staph epi and p.Acnes.On (b)(6) 2017, the patient's bcdva decreased to 20/100 and the inlay was explanted.During the procedure to lift the flap/remove the inlay and remove the epithelium sheets with a prk spatula, there was a small area of flap damage (5 x 5 mm) at the 7-9 o'clock position.The patient was treated with amniotic membrane transplantation and a bandage contact lens was placed.Medications prescribed and/or administered included: tobramycin, vancomycin, bacitracin, lotemax, gatifloxacin, sochlor, maxitrol, prolensa, and durezol.The surgeon suspects the patient's evaporative dry eye (despite treatment) was a contributing factor.The patient's prognosis is guarded with amniograft/bandage contact lens in place to heal the persistent epithelial defect.At last examination on (b)(6) 2017, the patient's bcdva was hand motion at 3 feet, but the amniotic membrane was still on the cornea.Additional follow-up will be requested.
