A British toddler recently had his right eye sliced in half by a neighbor’s drone, which resulted in the removal of his eyeball. He will eventually be fitted with a prosthetic.

According to BBC Watchdog, Oscar Webb was just 16 months old at the time of the accident. He was out playing in front of his home in Stourport-on-Severn, Worcestershire when a neighbor’s drone hit him in the face. Pilot Simon Evans, a next-door neighbor of the Webb family, flew the drone in front of his house, where it clipped a tree and "spun out of control" for a moment before colliding with the young boy. (The BBC described Evans as an "experienced" drone operator.)

"It was up for about 60 seconds," Evans said. "As I brought it back down to land, it just clipped the tree and span round. The next thing I know I've just heard my friend shriek and say, 'Oh God no' and I turned around and just saw blood and his baby on the floor crying."

The accident, which took place seven weeks ago, is likely one of the worst known consumer drone-related accidents. Amy Roberts, the boy’s mother, told the BBC, "What I saw was what I thought was the bottom half of his eye, and it's the worst thing I've ever seen."

Webb immediately had to have multiple eye surgeries before doctors determined that his eye needed to be removed. "I've not seen one in somebody so young, and I've also not see one from a drone," Dr. Faye Mellington, a consultant in oculoplastics and orbital surgery at Sandwell and West Birmingham Hospitals NHS Trust, told the BBC. "Any instrument that can come close to the eye and at high speed can cause devastating injuries."

Evans has reportedly been forgiven by the family for the "awful accident" and said he has not flown another drone since: "I look at the drones in the garage and I feel physically sick."

Both British and American aviation authorities have recently released safety guides for drone pilots.

UPDATE Tuesday 2:54pm ET: Ars spoke with Dr. Mellington, who said that Oscar will likely be able to lead a normal life as he grows up.

"On the whole, we are absolutely delighted at his progress," she said. "He's happy, he's tolerating it very well, his eyelids are fine. We're expecting a good cosmetic outcome. On the whole, I think he will be very well indeed. Lots of people manage with just one eye."
