Had the bandage removed from the right eye yesterday. The vision in that eye is bright, sharp, with vibrant colors that I had forgotten existed. Then I noticed that he put in a lens to make me far sighted in that eye when I had made it a point that I need to be near sighted in both eyes. If something can go wrong... Still happy with the result, will try to get the other eye near sighted when the time comes.

That's usually the technique doctors down here use. They leave you with one near sighted eye, and the other far sighted. That way, they say, it minimizes the need to use glasses.... although when I ask them about the diminished distance perception capability and the cancellation of stereoscopic vision they normally give me a blank stare... I guess they're not used to people asking them things like that.
 
Yes, I showed that in one part of the drawing but apparently I left off the ground connection details in at least one of the drawings. Sorry for the confusion.
Necessary? No, you could do without it and use a separate power switch. But I had to buy the dual-gang pot anyway and the cost is essentially the same if you get a switch built into it.There is only one dual-gang pot. The built-in switch is used to switch the power while the variable resistors are for the output adjustment. It appears twice in the drawings, for clarity, but it's the same device.

A gap in the resistor numbers happens naturally in LTspice - it labels each resistor sequentially - when you delete a resistor and do not edit the remaining numbers. I was too lazy to make sure there was no gap.

Thank you for the timely help. Sorry, I am a novice, hence disturbed you a lot. After receiving the IC's TLV272 I will able to complete the unit and will inform you accordingly. Thanking you

At the outset let me request your permission to submit the following request:
If it is possible for you to design a simple Voll instrument using a calibrated micro-ohmmeter to measure bioelectric impedance on certain acupuncture points located on the hands and feet in response to changes in the physiological functions of organs and structures of the body. This process also evaluates bioelectric impedance of acupuncture points when substances, such as medicines, herbs, supplements, and homeopathics are placed in the same electrical circuit with the patient (compatibility test), which will be of great help to reduce financial burden and stress due to unsolvable health problems please. Thanking you

To my knowledge, there is no scientific basis to such devices and they're strictly for psychological manipulation of the "patient" (victim?). If you can cite scientific papers that say otherwise, I suggest you start a thread on the topic. Be as specific as you can about what the device needs to accomplish.

About 12 years ago I was blinded with cataracts and got the foggy old lenses replaces with synthetic ones. The next day up to today my vision is perfect.

On TV they advertise Doctor Ho (I doubt he is a doctor) showing his expensive machines that zap your muscles to make them twitch. I think it is much better to use your brain to do some real exercise.

Actually TENS and NMES are quite popular for muscle stimulation. The NMES versions are used to retrain the brain when nerve tissue has been cut or damaged. While I see Dr. Ho as selling well overpriced snake oil the concept of using electrical impulses for muscle stimulation is a very common and approved medical practice. When nerve tissue is severed there is no using the brain to do some real exercise, sort like trying to light a lamp using a severed extension cord which I am sure you can relate to. You may want to study the subject matter a little before offering non medical advice like "I think it is much better to use your brain to do some real exercise".
