Here’s the story. I offer it for encouragement to those of you with bad eyes and a little extra cash, and to everyone else as a horrific cautionary tale of the limits of mortal man’s technology. Haha, just kidding. As you will see, there are no limits. We can do anything.
I went in Saturday afternoon to the place in Gwangju. They basically gave me all the same tests over again, but with slightly better English; so my corneal sickness was revealed to be corneal thickness, which is much less worrying. The doctor told me exactly how the surgery would work: the Da Vinci laser (he was ahead of his time) would first cut a corneal flap, a very shallow 3/4 circle around the orbit of my iris. They would then lift this, exposing the cornea, the important part, and then blast that with the Excimer laser for about ten seconds. I thought Excimer was a pretty cool name for a laser, and was comforted by that fact. This laser does the actual work; it shaves micrometers (that is, millionths of a meter) from the cornea, reshaping it into a more perfect lens. The science behind this is, frankly, amazing. The laser tracks eye position 4000 times per second, and adjusts accordingly. The doctor can control it on the nano scale.
Alternately, the doctor said, they could just pluck out my organic eyes (or “meat eyes,” as he kept calling them) entirely, and replace the whole affair, down to the nerve level, with a top-of-the-line cybernetic imaging system. This would have a higher cost, both in money and humanity, but would enable me to see into the infrared and ultraviolet spectra - but not the gamma spectrum, so I decided against it.
Then I waited, and waited, and waited some more, and then they finally slapped me in a hospital gown and led me into the “blasting chamber”. There was a bench, which I approached with some reluctance, over which was an arch with all sorts of lights poking from the bottom - the Excimer array. I laid down, stared up into the straight-from-a-UFO array of lights over my head, and started to get nervous. They put a speculum over my eye, cranked the lid open, flushed it with some solution, and went to work.
First, says the doctor, look at the green light. Absolutely do not look away. Watch the green light. If it disappears, keep watching where the green light was. Do not look away. “Or you’ll go blind” was implicit, but I knew what he meant. Machines hummed, and the doctor and a cadre of assistants were all cheerfully telling me not to move, in chorus, for about ten minutes. It was hell. I wanted to kick machinery and nurses, but I didn’t dare move. I wanted to scream. I just clenched and unclenched my fists and said, “Mmmf”. We had almost started.
The doctor finished his measurements, then swung out a plastic arm from the array that locked directly over my eye. This was the Da Vinci laser. They switched it on; orange light flared out and eclipsed my vision, then a black void grew from the center of the orange light. It was like I was being forced into another dimension, which at that point I welcomed. My eyeballs were numbed, but I swear I could feel it cutting, like a pencil dragging lightly across my eye. Enough to alarm me.
Then the doctor lifted the flap, “with spatula,” he said, and there I was with my eye cut open. Everything became very blurry. I could tell that there were still lights above me, but no shapes and few colors. It was surreal in the extreme. They swung the Da Vinci laser away and spooled up the Excimer.
You know when you’re at the dentist, and they keep rinsing your mouth or whatever, and you want nothing more than to close it? This was like that, except the penalty for closing is lifelong blindness. (I think.) It was extremely uncomfortable. From the green dot, at which I had been staring as if my life depended on it, a halo of red light expanded, expanded, covered my entire field of vision, brighter and brighter. It was evaporating my corneal cells. I swear I could feel pain. This was mostly in my head, I’m sure, but I could feel it, faint and distant, as if my eyeball were in another room, but I could feel enough to get worried. Then it was over, and the doctor was replacing the cornea flap and smoothing it with the spatula, which was a very strange thing to see through my numbed eyeball. Like someone mopping the other side of a pane of glass.
The doctor told me they were going to put a protective contact lens on, and I said with a sort of delirious happiness, “Do it! [And be damned, you!]” I’ve never been able to put on contacts with anything short of hellacious difficulty, but with my eye screwed open, it was the easiest thing I did all day. I had a good laugh about this, in my head. No one would have understood it anyway. Then there was a sharp pang as they released the speculum; normally they attach it to your eyelashes, but mine are so long and sensual that they just pinched a good chunk of eyelid instead. I exhaled for the first time in four minutes, and the doctor said, “Okay, now the other one.”
I’ll spare you that account - like the first, but worse, as that cornea is thicker and needed extra lasering. We rode home with a Korean family who happened to be at the clinic that day and lived in the same city as us. I felt fine at first. My vision was already better, I could tell, though quite blurry through the thick protective lenses.
On the way home, the numbing drops wore off, and I began to enjoy intense pains. I came up with two analogies for this exquisite sensation; at time it felt like ice picks plunged into my eyes, at other times as if my optic nerves had been rewired to carry not nervous electrical impulses, but red-hot magma. All I could do was rub my temples and rock back and forth. Randi did me a world of good by squeezing my hand. (Seriously. It’s remarkable what such a simple gesture will do when you’re suffering. I must remember this for my further interactions with hoo-mans.) When I got home, all I could do for the rest of the night was pace in the dark while listening to an audiobook of Roald Dahl short stories. Within four hours of the surgery, though, the pain had subsided, and when I woke the next day, it was gone completely.
So was my-opia. Things were a bit blurry from the lenses, but I knew there was a significant improvement. But I couldn’t imagine how significant. In the pre-surgery form, they tell you that they’re shooting for 20/40. When I went to the doctor for my follow-up exam, he told me that I now had better than 20/20.
Previously, with my glasses, I couldn’t make out facial features on the other side of my classroom. Now I can make them out on the other side of the cafeteria. When I looked out the window, I would see a leaf-textured tree shape; now I can see the individual leaves. I can look across the rooftops and see where the old women have spread out red peppers to dry, and see the individual peppers rather than a red mass. I can see not only individual bricks rather than brick-colored buildings, but I can see the rough textures of the bricks. I can see the pebbles on the playground rather than just dirt.
There’s still some eye strain when I try to see stuff within arm’s reach, so I can’t yet read books, which sucks. I can watch TV and play PS2, but not PC games, because they’re closer. When I’m looking at something close and then look at something distant, there’s a moment of weirdness as my eyes refocus. Otherwise, I have absolutely no side effects. It was an unqualified success. I am well pleased.
