Yag laser is only good for blurred vision. It does not cause pain or redness. Pred Forte 1% is a suspension. It will say on the bottle in fine print to shake. Many pharmacists put an extra tag on the bottle saying to shake and the prescribing information given when you buy the medication says to shake. I still feel you need to see a consultant. If your optometrist saw inflammation that is a problem. A low grade infection (endophthalmitis) can cause ongoing infection in the eye can can be difficult to diagnose. In describing why you need to go to a referral center you have ongoing pain, redness, sensitivity to light and blurred vision and your local doctors don't seem to be able to find a cause.
Many good places in TX. Baylor is wonderful. This is a internationally known doctor that specializes in post cataract surgery problems: https://www.chistlukeshealth.org/physician/Douglas-Koch-12777 If he can't see you another anterior segment surgeon in his department would likely be excellent. Also the Dean McGee eye institute of U of OK school of medicine is great. This is a link to all ophthalmology programs in Texas. All strong programs: https://www.residentswap.org/Ophthalmology/TX/ You could also go to Mayo Clinic in Florida, Vanderbilt, Bascom Palmer eye institute of U of Miami. It would be best is you could find one close enough to drive within a reasonable time. You may have to pay a duplication fee for your old records but legally they have to be provided to you upon payment and in a reasonable period of time. If not you can either send your lawyer to get them or you can call the county medical society and make a complaint.
Intraocular lenses (IOLs) used in the United States are of high quality. While patients are given a choice of monofocal, toric and multifocal , they are not given choice of brand names in most cases. This is the same as for most prosthetic devices used in the human body (hip replacements, heart valves, cochlear implants). Hospitals cannot possible stock all implants and the implant should be one the surgeon is familiar with. Your surgical outcome is decidedly abnormal and you need to see an Eye MD that specializes in post cataract surgery complications (which are few in number, cataract/IOL surgery is the most common and successful surgery done on adults). If you live in a major US city I suggest the ophthalmology department of a University School of Medicine.
