Post #12: Progress Update 6 Weeks after Surgery - August 3, 2020

Things have progressed well with the vision in my right eye over the last few weeks. I am now getting very good focus at all distances and my brain seems to have really figured this IOL out. I can quickly change from looking at objects in one range to looking at objects in another and whatever I shift my focus to comes pretty much instantly into focus.

For example, I can be sitting up on a deck looking at the palm of my hand 15 - 20 cm (6" - 8") away and I see every little line and detail in my hand in very sharp focus with very fine detail. I can then look over my hand at the deck railing about 1.2 - 1.5 m (4' - 5'0) away and instantly, the railing appears sharp and focused. My hand now appears out of focus as are objects off in the distance that are visible through the rails. If I then shift my focus on some object 40 - whatever m away off in the distance that I can see through the rails, those objects come nearly instantly into focus and the rails which I was just focusing on, now appear slightly out of focus in the foreground. If I switch back to focusing on the rails or my hand again, whatever I want to focus on, comes nearly instantly into sharp focus. And no matter what the range is, I'm getting a very sharp focused image with amazingly fine detail.

Sometimes, when I close my bad (unfixed) left eye and look at something at whatever distance with with my right eye only, I will notice that just for a fraction of a second that object may not appear to be in perfect focus and then, all-of-a-sudden, it is in perfect focus.

These things tell me that my brain has neural adapted to this IOL so well that no matter how close or distant something is that I shift my gaze to is, my brain knows virtually instantly what part of the signal on the retina to process and which parts to filter out in order to get the sharpest possible image. To me, it seems remarkable that our brains are so resilient and adaptable; that Doctors can rip out the optical lenses of our eyes that we have lived with and gotten used to for several decades and replace it with a new lens that's completely different in EVERY way and even if we are older, our brains can completely adapt to and master that lens within just a few short weeks.

So I think at this point, it's safe to say that the question of whether I could neural adapt to and see well at all distances with the Lentis MPlus IOL during the daytime has been answered. Yes I have and I can. The next big question is whether the haloing, starbursting and glare effects I'm getting at night (especially when driving) are going to diminish over time. I will begin to address that part of the equation in future posts. 

In the meantime, I'm scheduled to have IOL replacement surgery to fix the cataract in my left eye on Aug 19th. I will be having another Lentis MPlus IOL implanted into that eye as well.
