To read some people's comments, my opinion that the annoying tendency of the DSC and PIC writing staff to use, reuse, overuse, abuse, and misuse the "eye scream" trope (cases in point, the maiming, murder, and possession of Leland by Control in "The Red Angel," the death of Icheb in "Stardust City Rag," and the two "eye scream" invocations in PIC episodes that I haven't gotten to yet) were gratuitous gross-outs as well as poor artistic choices (sacrificing good storytelling for the sake of expediency) is a controversial opinion.
Of course, for the sake of full disclosure, even though people I know (my own parents included) have gone through successful cataract surgery with prosthetic lens implantation, I'm so hypersensitive to "eye scream" that if I were presented with a choice between eye surgery and going blind, I'd have to think long and hard about it. And assuming I did choose the former, I'd require full-blown general anesthesia, and probably professional aftercare. And the one time an ophthalmologist tried to get IOP readings on me with a contact tonometer, he eventually gave up and took me into his pediatric treatment room, where he kept his air tonometer.
