I had near-perfect vision less than 2 years ago. It was somewhere close to 20/20, aside from some mild myopia, or nearsightedness, that I had developed in my early 20s and did not even wear glasses for.
Then, the keratoconus (KC) developed and went wild and you can read my blog for that saga. I was at my corneal specialist’s recently as he wanted to see me for a 6 week follow-up after discovering central corneal opacity, or scarring, in my right eye months after my bilateral cross-linking (CXL) surgery.
Despite what I have felt has been rather negligent care, I got the full workup at the appointment: reading 2 eye charts, a refraction, a corneal topography, a corneal pachymetry, a check of my ocular pressure, and who knows what else I forgot. I was in a bad mood due to the disorganized clinic and was not really sure why I needed all the tests when I just had them done, but asked if I could at least have a copy of my topographies since nothing was initially sent to my CXL surgeon in L.A. for the clinical trial.
The techs are nice and had no problem with my request of having 4 papers copied, as opposed to the last time when I asked the front desk girl, who said she would have to charge me. Now, I finally had the scans I needed to see what my corneas and KC really look like at this stage, although my surgeon confirmed the other week that per my scans, the CXL was successful in both eyes and the progression of KC has been stopped in its tracks. Thank the Lord for modern medicine.
After all the testing and finally seeing what I could of those scans myself, the doctor rushed in talking a million miles a minute. He never seems to remember who I am or what my post-op issues are, which is really frustrating. He asked if I had any improvement since I had last seen him and I replied that I had some intermittent watering in my left eye—possibly due to the Restasis starting to work after 5 months—and that my right eye with the scarring had the same vision, which is a good sign, as well as the fact that the horrid light sensitivity (sun burning my retinas) was better, but not gone. He did a quick check of my eyes and said, “Good. Good.” That told me nothing, per usual, so I began with the questions that he hates, as he is already making notes in my chart at this point.
Here we go with the issues to preface all this. I read 2 eye charts—from right to left my visual acuity (VA) is now 20/40, 20/40 on one chart and 20/30, 20/40 on another. My left eye had gone up to 20/60 at my last appointment, so I was dealing with a post-op fluctuation that has cleared up. To err on the side of caution, I will say my vision is 20/40 with great difficulty on those last 2 lines, as no one has had me read the charts with both eyes, or binocular vision, which often gives a better VA. Would my true visual acuity not be of importance post-CXL? Well, of course, but I am dealing with sub par healthcare here. However, the big question is: why can I not see?
I should add that I do have a bizarre zone where I can see somewhat normally—it seems to start 1 foot in front of me and stop at 4 feet or so and there can be no sunlight or bright, artificial lights or the whiteout sets in. This is the safe zone and aside from a plasma-type TV on a not-too-far wall, I get staggered vision of everything outside that space in small rooms. For a description of how I see outside, in big spaces, and in the world in general—also known as the Ghosted Mess—refer to this post.
I have to ease my way into questions or my doctor gets irritated and the appointment ends, so I started with the basics. I wanted to know if the Restasis was causing the intermittent watering in my left eye, or if that was just from my corneas finally starting to heal from the surgery, as Ehlers-Danlos syndrome (EDS) is causing very poor and slow wound healing. The doctor could not answer that one. He kept saying my eyes were dry due to my meibomitis (MGD), which causes a lack of lipid (oil) layer in the tears, and that I just need more IPLs. I told him I had my last IPL 2 months ago and his associate—the doctor I like who specializes in dry eye—said more IPLs would do nothing at that point and I would not need a touch up for possibly a year.
I had 5 IPLs with no improvement that I noticed. However, the doctor thought they were successful in terms of the meibomitis, but as my eyes stopped producing the water layer in my tears post-op, they were still dry as a bone. Yes, this is all confusing, but for more information on MGD, as well as post-op dry eye, refer to this post. The corneal specialist gives me an odd look every time I explain that my complaints are related to my lack of a water layer and he says that I could barely open my eyes due to the meibomitis before the IPLs—although I only saw him once since 2010 and never had that symptom so I think he has me confused with another patient. Can I just see the dry eye specialist instead?
That leads to the big question—if my vision is roughly 20/40, why am I visually impaired? 20/40 vision is legal to drive in most, if not all, of the U.S. and I am not too sure I should even be on the road late at night, let alone left to wander in a big box store, which I would like to peruse with a stiff drink to offset the anxiety from the chaotic mess. Why do people look like shapes and colors and nothing more, unless they are in my safe zone? Well, the doctor is not sure, of course. What is he sure of? Why is he a doctor? Why is he the best corneal specialist in this horrid city? I may have better luck getting answers from the local fortune teller, who happens to be in the jenky strip mall next to my motel.
Now, I am not an ophthalmologist, but I am quite capable of interpreting my scans. Per the topographies, my better eye pre-op has no evidence of KC now in either the scan—showing no corneal steepening and 0% severity—or the K-readings, which are in the normal range now. My worse eye pre-op decreased in severity by 32.5%, although my K-readings are relatively the same in that eye, thus showing keratoconus—although it will not progress further due to CXL. K-readings measure the curvature of the cornea and there is still a significant steepening, which I can also see in the color-coded scan, but it appears to be much less severe, which makes no sense, especially since I got 6 or 7 lines of vision back in that eye. Both topographies do look quite different from my pre-CXL ones, which is rather fascinating. So, it would appear that I would have no keratoconic vision in my better eye, yet there is from my vantage point and I do not have my old 20/20 vision, regardless. May I also point out that at my last appointment, my doctor could not even tell me if the CXL had worked in that eye. Can I please move to L.A. with a giant dehumidifier and go see my surgeon for follow-ups instead? As mentioned, even I could interpret that scan with my impaired vision!
Back to the question at hand—my doctor asked when I would be seeing my surgeon again, as he seems to think I am able to go to L.A. at the drop of a hat—even though I would need an all day ride, have to pay a huge cash sum to see my doctor, and rent a motel room there, while living in one here. I reiterated for the 100th time that I have not seen him since my surgery in September of last year due to X, Y, and Z—not to mention that my local doctor referred me there and said he would handle all my follow ups. My patience was wearing thin.
Then, he asked how soon I could have laser vision correction surgery done there, even though that is my local doctor’s specialty (hence, corneal specialist). Is he crazy? I am 7 months post-op and a poorly healing, scarred mess due to my EDS and he thinks laser vision correction—namely PRK, which to my knowledge is still being studied for safety in post-CXL eyes (please fact check that), is a good idea? Due to the weak collagen structure in keratoconic corneas prior to the development of CXL, laser vision correction is contraindicated and is why all laser vision correction patients are given a topography to look for any evidence of KC before LASIK or PRK surgery. My eyes are so dangerously dry, plus the central corneal opacity that is no worse 6 weeks later but has not resolved, and he is even considering this? Furthermore, upon researching this issue just for the hell of it, the only scholarly, research articles regarding PRK following cross-linking involve or reference this ophthalmologist in Greece, who is on the payroll:

Maybe it is best to just see the local shaman wandering in the desert at this point. Perhaps some native shrub, like tumbleweed, can fix my vision—or is the local shaman in on the hustle to further destroy my corneas for some exorbitant fee, as well?
I told my doctor—who I now have absolutely no trust in—that there was no way I would go through surgery again with all the complications I have had and he mentioned something about my vision being bad from astigmatism. What astigmatism? Irregular astigmatism aka keratoconus? 9 months before my diagnosis, the optometrist I saw had misdiagnosed my keratoconus as mild astigmatism in my worse eye. Was this something new that my doctor pulled from the refraction done that day that I was not given a copy of? Add it to the list of copies I will be paying for very soon.
So, aside from residual keratoconic vision and little improvement in my K-readings in my worse eye, which I still don’t understand if the cone is so much flatter per the topography, is massive astigmatism in both eyes—the normal kind—contributing to the significant visual impairment now? If so, why can I not see any better with a refraction, just like when I had one before my diagnosis. I just answer, “Same” every time they flip the lens and ask, “Which is better—1 or 2?” Is the KC cancelling out any hope of lenses correcting the astigmatism? Why can I not get correction in my now non-keratoconic eye like my brother who has astigmatism and gets by fine with glasses? I am so utterly confused and Dr. Corneal Specialist is of no help.
As I have no choice but to wait and hope my vision improves a little more as my corneas continue to heal, patience has now been added to the survival box, and while I twiddle my thumbs, I will keep crunching the numbers in attempts to resolve the elusive mathematical equation involving my VA: 20/40 = X.
