Who should I choose to represent my case in Houston concerning damage to my eyes? Could this potentially be a huge case/cases huge compensation?

Case #1: It isn''t known how Keratoconus (Progressive eye disease) is caused. But I didn''t start receiving symptoms of vision loss until eye injury occured at my previous job, which also caused a hole to form in my retina. Case #2/3 Pt. 1: In February I started going through D.A.R.S (Division of blind services) for help with my vision. They were aware of my Keratoconus, and retina damage. They were supposed to send me to a retina specialist, but as of today, it still hasn''t happened. Instead throughout the time with them sent me to a low vision specialist which brings me to case #3 Case #2/3 Pt. 2: Dr. ordered hard, plastic contacts. Fittings were wrong, and I''ve been in constant pain. She "forgot to polish contact". Then a few hours after polishing, I received an "abrasion of the cornea". Medication subscribed didn''t work. A month later eye still injured, and D.A.R.S took a month after calls and emails to help me. Symptoms of light sensitivity, illusions of spots etc.
