Well back to the hospital today.
Appointment was booked for 4:10, I arrived early at 3:30ish on the off chance only to find a sign saying “Mr DeCocks surgery is running approximately 35 minutes late” – at least they let us know.
At 4:30 one of the consultants students appeared and we did an eye test, the vision is better than it was a couple of months ago and the student seemed quite impressed, I am really happy as with the pinhole glasses I could read all but the bottom two rows. I asked if it was possible to have a closeup photograph taken, and was not sure that she understood me (lack of english I think) and then she started going on about having a scan and that I would not understand it. She repeated that phrase a couple of times “You would not understand it”. I asked if she was implying that I am stupid, it was worth it to watch the colour drain from her face as she did the “Oh no I did not mean that”. Anyway that was the eye test so again I went to wait in the waiting room.
Some time later (not sure how long as I was engrossed in my book) I was called in. I didn’t get the consultant himself, I had his number one assistant by the look of it which was fine as I could tell he knew what he was doing.
We discussed the vision I was getting (which is very good), straightening out my eyes as one is lazy and this will be looked at later on when the graft has settled down. He did tell me that when the eyes are straightened out there is a possibility that I will have double vision, so in the meantime to use the lazy eye (grafted) as much as I can, as I will get used to using it, despite it being mental effort to do so at the moment.
I asked about the possibility of having a photograph done, fortunately he understood me and said that its possible but not today as they didn’t have all of the equipment with them today but that he would try and get it for the next appointment. In the meantime I have to stick with the steroid drops twice a day for the next three weeks and then down to once a week until I come in again. An appointment will be made to see me in six weeks time.
At this point things started to get exciting (well for me anyway), as I was told that they wanted to do a corneal topography on both my eyes. For the grafted eye to really measure how things were shaping up and for the other eye to measure how bad the keratoconus really is. So I sat at a bench with my head in a sling looking down what can only be likened to the time tunnel from the TV series of the same name. I was a cone with concentric rings alternating black and white with a red LED at the end. For the process it was lit for a few seconds so the white rings went bright yellow, the light was extinguished and a white LED thingy whizzed in front of my eye. All in all it took around ten seconds.
I noticed a big LCD screen at the side with loads of colour diagrams and has to ask what was going on. Apparently the piece of kit, measures the surface curvature of the cornea and the curvature of the innermost layers of the cornea and can work out how light is refracted inside the cornea. Amazing. Anyway I noticed colour print outs and asked if they could print two copies. Once again the junior did the “you would not understand” bit, and then the consultants voice was heard from the room next door to saying “give Mr Osborne a copy of the printouts” and so she did!
Armed with the printouts the number one assistant started to explain the diagrams to me, how they show the curvature and the light refraction, to which I chipped in with something like “so these figures are in diopters and becuase this area is all blue the surface at the back is fairly flat which is what we are after and shows that the keratoconus is not an issue in the grafted cornea, where with the other eye we can see the light being refracted all over the place?”, the assistant looked at me, smiled and said that that was exactly what the diagrams were showing. The junior in the background looked somewhat sheepish.
Anyway follows are some pictures:

This shows the surface curvature of the grafted eye, the high point being red is pretty much in the centre, there are chunks missing on the sides where the graft boundary and scarring confuse the machine (so it gives up).

This is fairly even (apart from the green spot) and shows the level of refraction through the cornea is pretty much consistent and so is sitting smoothly spreading light as it should do.

This is the cornea surface curvature on the right eye, the high point is over to the left, in both cases the oval shape shows the level of astigmatism.

This kaleidoscope picture (!) demonstrates that through the cornea the light is being refracted all over the place and shows the extent of the keratoconus in the eye. The left eye had it had these measurements taken before the operation would have looked much worse apparently.
