"Split focus view finder"

I have a year old D7000
I installed a 3rd party view finder ..... prism? .... when I bought the camera. I can't remember the brand name. It has been brighter and a tad easier to manual focus than the original. But the difference is not much.

1000 years ago I had a split screen view finder on my ancient and totally manual Nikon F. Manual focus was easy. Even though I have relatively poor eyesight, I would twist the focus ring until two split edges of the subject came together. Then I knew I had razor sharp focus.

D7000 automatic focus (even in spot mode) is troublesome. I like to use a 400mm lens up close. That gets a bit like macro, where you have very little depth of field. The autofocus on birds is always sharp as pistol on the bird's leading shoulder, and a bit blurry on the eye. You can use AP mode on a smaller aperture. But what you really want is razor sharp focus on the bird's eyeball. No matter what.

I'd give up on autofocus. But I'm 63 and my eyesight is sliding downhill fast. Is there a 3rd party product? Any way to make my D7000 have a split screen manual focus?

Or do I need to buy new camera?

Katzeye appears to be the one to get.

I have the Katzeye. It is a bit easier to use than the stock Nikon view finder. But the difference is subtle. The spit image in the middle of the view finder is small and hard to track.

My old Nikon F was far easier to use.

There's one other on the market here:

. . . but the split is no larger than the one in the KatzEye focusing screen. Maybe it's also time for a stronger diopter eyepiece for your viewfinder?

If you are getting sharp focus on the shoulder but not the eye it would seem your focus point is off. Are you placing you focus point/slit prism on the eye of the bird or somewhere else?

OK. I'm an aging amateur, still learning how to use my new camera. I need to figure out what focus lock is and use that I guess. Birds up at maximum close, right at the nearness limit of 400mm only give you about one second to shoot at best. And then they're gone. So focus, lock, recompose, press shutter is......what separates professionals from duffers I guess.

I do a lot of studio work with captured but still alive insects, and with macro closeups with fishing flies. Lazer sharp focus makes all the difference. It's easy in the studio. Difficult in the field.

One of the best all-around bird photographers I've run into on the net is a Texas birder named Dan Pancamo. He has hundreds of lazer sharp field closeups. Not backlighted is important too. I think in that regard you have to train yourself to not even look for birds when the lighting is behind the subject.....and to work late or early, when the lighting is not prohibitively harsh.

I like the stronger diopter idea mentioned in another post too.
Thank you all for responding.

Here's an example of one of my almost but not quite photos:
