Help needed with corneal topography please!

[LalitaCJ]

Hello, my name is Laura,
I am glad to find this forum which I hope will be helpful. My sister suffers from vision problems; she has been diagnosed with keratoconus, corneal ectasia, and irregular astigmatism. Her diagnosis has been difficult and even differs from one professional to another. Over the years several factors may have made her vision worse. Currently she is 38 years old: at 22 she had radial keratotomy surgery after which her vision was much improved. However, after 6 years it began to decline significantly and quickly until she was told she had corneal ectasia and irregular astigmatism. She used rigid gas permeable lenses + soft Piggiback lenses but her eyes did not tolerate them making it impossible to wear them probably due to incorrect measurement. After that she used kerasoft 2 but her vision was blurry, again perhaps due to poor measurement. 4 months ago she started using Boston rigid gas permeable lenses and her vision improved but she is feeling uncomfortable like needles in the eye, and also has photophobia and watery, irritated eyes so she is not using them for long periods.
I live in England but my sister is in Bolivia. She has seen different doctors in various cities but has had little success due to lack of resources. She was told that it would be best to have a corneal transplant which terrifies her. I promised her to try to find someone who can help us and be able to read her topography which was measured with OCULUS – PENTACAM hoping someone could advise us about her options for being able to get accurate lenses for her problem. She is not able to deal with the daily pressure of life with 3 kids and a job with her poor vision. Please help!
Thank you.
