About a year and a half ago, I dropped my iPad while on a flight from Japan to the US. The screen cracked in the top corner. I tentatively touched the screen, to see if the crack was dangerous. I did not cut my finger, but did succeed in transferring a very small piece of glass to my finger.
People touch their eyes frequently, often unconsciously.
Six hours later, after attempting self-irrigation on the plane and at the airport, I was at a hospital in Chicago seeing an eye doctor. Time from arrival at proper floor to being taken to room: three minutes ("glass in eye" cuts down on paperwork quite a bit). Time to arrival of doctor: approximately four minutes after that.
They successfully treated me for, possible misquote, "non-traumatic introduction of a foreign body to the eye." (The attending physician's first words, after reading the chart, were "How in God's name does an iPad screen end up in your eye?")
Treatment was approximately 15 minutes of a resident's time and 5 minutes of the attending physician's time plus one cotton swap and some iodine.
Total cost: approximately $300, plus twenty minutes of dealing with the billing clerk (after approximately 30 minutes of waiting for the billing clerk to be ready).
Most of the time with the billing clerk was a result of the clerk getting the run-around from a Japanese commercial travel insurance company. I customarily travel with private insurance which, among other things, covers me for medical emergencies while traveling. (Normally I'm covered by Japanese national insurance, which doesn't normally cover treatment of Americans in America for all the obvious reasons.) The insurance company denied reimbursement for elective medical treatment. Direct quote: You could have elected to leave it in your eye.
