My best friend has just gone through this. Her eyesight was more or less fine (just needed bog standard glasses), but the ophthalmologist noticed she had a degenerative condition that would almost certainly lead to blindness in the next 20 years. They recommended a routine, preventive surgery… after which she was in excruciating pain for 3 weeks (bad enough to be hospitalized overnight) and could only see things in a way that was misty and shadow-like for a solid 5 months. It was profoundly distressing, and she had several panic attacks and depressive episodes over those few months.
What ultimately helped her was finding a better ophthalmologist, who she really trusted (she went through 4 first, I think, and had to really advocate for herself). With that ophthalmologist, she created a list of the possible interventions that remained, in the order they would try them in. Something like: 1) different steroid drops, 2) a third different set of non-steroidal drops, 3) corrective glasses, 4) wait 6 more months to see if healing occurs naturally, 5) corrective contact lenses, 6) repeat of the original surgery, 7) attempt at a more experimental procedure.
Then we took that medical plan, and together traced out the non-medical elements of life she’d need to figure out. E.g., if she got to 3), another friend and I would help her fund the glasses which she couldn’t afford. If she got to 4), she would apply for medium-term disability benefits and workplace accommodations and start seeing a therapist; if she got to 5) she would sell her car since she couldn’t drive through any of this, and she would join a local support group for the partially sighted, etc.
Talking about these things was initially overwhelming, but once she had a list of future actions she could take actually written on paper, life felt a bit more under control.
Thankfully steps 3 & 4 combined worked, and she didn’t need to go through any additional surgery. 8 months later, she’s back in her regular job, able to drive (though not at night), and beginning to be able to put the nightmare behind her.
I don’t think anything could have prepared her for how terrified and powerless she felt during those months, but “planning for the worst” with friends and in therapy helped relieve some of the anxiety. Might be worth a try!
I’m so sorry you’re going through this!
