The explanted inlay was returned to the manufacturer and subjected to visual microscopic inspection and dimensional analysis.Visual inspection revealed that the inlay did not have a cloudy appearance.Dimensional analysis (measurement of edge thickness and diameter) was unable to be performed due to the damaged condition of the inlay, which was torn into 4 separate pieces; the pieces were observed with cuts and particles on the surface.Since there was no report of inlay damage, the damage is presumed to have occurred during the explant procedure, where damage can occur from the surgical instruments used to remove the device from the eye and place it in a hydrated storage container for transport.The device history record review of the manufacturing lot was performed and there were no discrepancies or unusual findings related to the reported issue.Corneal haze is listed in the device labeling as a known potential risk.(b)(4).

The patient underwent uneventful implantation of the raindrop corneal inlay in the left eye on (b)(6) 2016.The inlay was explanted 10 months postoperatively due to corneal haze on and around the inlay that persisted from 3 months postoperatively until explant.There was no significant decrease in best corrected distance visual acuity, however, the patient experienced significant glare symptoms at night.Central corneal haze was present at the last examination one day post explant and bcdva was 20/25.Additional information is being requested.
