odd shaped corneas/difficulty correcting vision

Question
Hello, I would greatly appreciate any advise or suggestions regarding my vision issues. I am a 22 year old female, and have been wearing contacts and glasses (the best I can) for about 7 years. Contacts have always been very uncomfortable, some have floated, all of them have been somewhat dry, I can always feel them, it always feels like there is something in them, and I am constantly blinking. As a result, they cause me to get headaches and I usually take them out within a few hours of wearing them. I am currently wearing Air Optix, they are the best lenses so far, but I am still having the same difficulties minus the floating. I also had glasses made, (partial rimless) and they were making me extremely nauseous and somewhat disoriented, I felt motion sick. The Dr. told me to choose another frame that might work better, (completely rimless) and they gave me the same problems. I have another pair of glasses that I got last year from a different optometrist, and can see perfectly out of them, although the ear piece broke off so I don't really like wearing them super glued together. They are -1.25 in both eyes. The optometrist then changed my new glasses to the same prescription as my old glasses, and I am still having the exact same problem. What could be the reason for this? I have never had problems with glasses before. Last but not least, when I went back to the Dr., he recommended trying CRT lenses. We did try these, and went through three different pairs of lenses, all causing distorted vision. He explained to me that my cornea is not shaped like the average cornea, but more football shaped than round. He also said that rather than being completely convex, my cornea was wavy. He said that the meridians of my eyes were different. Also, that I had astigmatism, but that it did not show up in my prescription. I have also had a consultation for LASIK, and the Dr. said I was not a candidate for the procedure due to the shape of my cornea. At this point, I am willing to try anything. This is causing a constant problem in my daily life and career, and a constant headache. What would you suggest doing? Can this be corrected in anyway? Is there someone that could help me? I am desperate. I would greatly appreciate anything that you have to say. Thank You!!


Answer
Dear Lauren,



Unfortunately in your case, the best corrected prescription which suits you and gives you a comfort fit, has to be done by trials.



This would require you to have a good optometrist who would painstakingly check yur prescription and not rush it.



If there is a complex number or pwer (I dont know if thats the case since only one kind of power is mentioned), lenses may become difficult to make.



A cornea specialist could also look inot your case and see whats the best way out for you.



If there is a combination of treatment like correcting some power like a high cylinder by LASIK, some people benefit the LASIK treatment as it makes their complex spectacle powers simple ones, so do not look at options which may correct the situation in one go but maybe in steps...
