By all means, feel free to send us whatever findings you have, including examination results, prescriptions, acuities, etc.
Thank you very much. I have prepared a PDF file. Should I send it via an email to firstname.lastname@example.org ? I would feel more comfortable to not upload my examination results in public.
You say you went to three eye doctors to rule out keratoconus. Why were you suspicious of having keratoconus?
In the beginning of October I suddenly started to have accommodation issues. During this period of time, I also started to see severe "double images" for approximately one week when looking, e.g., at a PC monitor. I had troubles to see sharp (subjectively 50% of my 100% vision accuracy) and switched from soft contact lenses to glasses. After two weeks my sharpness returned more or less (subjectively 80% of 100%) and my "double images" and focus problems slowly almost disappeared, which I now rather call ghosting. I noticed that I'm more sensitive to light and that I experience increased light strokes. When I visited my first eye doctor and when I was telling him about my symptoms, he told me that this could be due to keratoconus, but he didn't have appropriate equipment (no PENTACAM, no Orbscan, no OCT) to examine this. This is the reason why I wanted to rule out keratoconus. I updated my glasses from (L:-6.00 dioptrins, R:-5.75 dioptrins) to (L:-6.5 dioptrins, R:-6.5 dioptrins) and obtained back my entire sharpness. It should be noted that I experienced similar issues 4 years ago (sudden loss of sharpness coming entirely back after 2-3 days), but never experienced any post-incident symptoms, which is unfortunately now the case.
Based on your description your problem is obviously something optical (as opposed to neurological). That would bring three things into consideration. (1) tear film, (2) cornea and (3) the physiologic lens. Since the drops you were given (I assume they were lubricating drops, i.e., artificial tears) gave you no noticeable improvement, I don't think the tear film is the issue.
Yes, these were artificial drops. I could imagine that both, (1) and (2), may be the case. Some light strokes are more or less constant and vanish away when my pupils shrink, but are not affected by any eye drops. Then, I sometimes additionally experience "dynamic" light strokes, which do change its size with each eye blink. These are influenced by eye drops, but not necessarily in a positive way.
It is especially my left eye, which is the problematic one regarding my symptoms. My right eye performs much better (almost no ghosting, only little light strokes). Maybe it is important to mention that when I tested one-day soft contacts, I also started to experience stronger ghosting issues on the right eye similar to my left eye with glasses. Hence, I didn't use any contacts since some months now.
The Pentacam should give a good indication if the problem is corneal. The third possibility is the natural (physiologic) lens. You are quite young to have changes in the lens but it's possible and somewhat consistent with your symptoms.
My second doctor told me that I have very clear lenses, which was confirmed by my third doctor. Is there a chance that bad lenses are hard-to-detect at an early stage?
Are you taking any medications?
I don't take any.
