Hello Dora
Sorry to hear of your hand and eye problems, but glad you sought a second opinion on your eyesight and received the correct diagnosis. I would steer clear of any doctor who told me to take a pill before doing anything physical.
I have carpel tunnel and arthritis in my hands so can appreciate the agony of cutting with scissors which I always use for making templates but can manage the roatary cutter for a while when needed.
I wear wrist splints provided by Rehabilitation section of the hospital, and have a solid plastic-type splint made especially for use when gardening and DIY projects - it is moulded to the shape of my hand and wrist so fits like a second skin but supports my wrists very well. There are commercial supports available for hands, knees, ankles and elbows etc.
So glad to hear your eyesight is improving in one eye and you're able to begin quilting again. Take care and have fun
