Think about the day to day activities that could be frustrated by loss of sight and aim to maintain them. E.g. dressing, cooking, cleaning, shopping, correspondence, socialising.
Also at 91 dealing with bureaucracy is a challenge in itself without the added burden of failing site. Making phone calls and filling in forms would be great help.
You could help make sure that she is connected to all the right organisations that will provide help.
/u/shacklebolt said check out the RNIB website, it is a fantastic resource, but I would go further and give them a call.

I think it is the local authority (LS) / social services who have some responsibility, e.g. supplying mobility aids like white canes. Your aunt will need to be registered with the LA as blind for this (
$1).
Being registered blind will entitle her to a Blue Badge, this will help anyone giving her a lift to be closer to the destination for them to guide them onward.
She's should be eligible for
$1. Applying for attendance allowance is a pig of a job, 52 questions on 31 pages, but you could fill it in for her.
Other benefits like
$1 may be available.
With this extra money she could employ people to help her with tasks like cleaning the house (seeing dirt is difficult when your blind as is using cleaning products safely) and going through correspondence (you need someone very trustworthy for this) or just reading the local newspaper to her.
Employing people is challenging, from interviewing and selection to making sure they are paid along with their taxes, holiday pay and pensions. There may be a local organisation who can help with this payroll administration.
Getting an appointment with an
$1 could get her illuminated magnifiers or monoculars or other aids to help her read things.
If she has an iPhone then
$1 app has great potential.
Help her get in touch with the local blind charity. They may do home visits, have examples of aids for blind people to try out, can give advice, offer a social centre where people can meet up in a blindness friendly environment.
Get her some
$1 so she can mark the preferred settings for toaster / cooker / washing machine.
$1 look really useful too, I think I may get some of those for someone I know.
Good lighting helps too,
$1.
Edit: Buying a screen-reader / magnifier software is just a start. Whether it is Voiceover on an iPad or iPhone, or PC software like
$1 then training and support is a must for any user to get the best out of it. Either pay for training or learn how to use these yourself and be the trainer.
