Hi Fatima -- very very sorry about getting the name wrong !
First off, yes, definitely register for DLA. Frankly if someone in your situation doesn't get deemed eligible then a) it would be a disgrace and b) you'd have to ask who
would get it. The forms for applying are pretty daunting though. As in, really horrible. What I'd suggest if you're not a real expert on filling in forms is to go along to your Citizens Advice Bureau and ask them to help you. There's one in Dunstable, hopefully not too difficult to travel to.
http://www.dunstablecab.org.uk/Before doing that though, I'd also sugggest you contact your GP (make an appointment to see him/her). Tell them exactly what you've told us here on the Forum (about how bad your sight is now and that you've had a corneal graft or grafts indicated as the only possible treatment -- which you're still considering). Say that you'll be applying for DLA and ask if the GP is okay with being listed as "the person who knows you best" on the DLA application form. Suggest to your GP that the opthalmologist should have sent a note of the diagnosis, but if they haven't then the GP might like to contact the opthalmologist, just so they know what the prognosis is. The reason for doing this is that, unfortunately, the DLA assessment team place way, way more weight on medical evidence than on self declarations or a layperson's opinion. Not right, but that's how the system works in reality. Hopefully your GP will understand how important this is for you. You could even print off this post and take it to your appointment, if you're anything like me when faced with a medical-type person, my normal intelligence abondons me and I end up gibbering inanely !
If your GP is agreeable, then go to the Citizens Advice Bureau (CAB) as I say and ask them to help you with the DLA form. If you are feeling really brave, you can apply for DLA yourself here:
http://www.dwp.gov.uk/eservice/ ... but given the severity of your visual impairment, I'd really recommend you ask for help at the CAB.
Finally, not an easy decision when considering whether to go opt for a graft; I know that I basically dithered for a whole year before deciding. It was one of the hardest choices I've ever had to make. Let us know if there are any factors about the decision which you need advice on. No-one can really say what is right or wrong for an individual but if there's information you need, probably someone here who can help find it.
Best wishes, good luck,
Chris
