What dangers are there in the removal of a retained cortex? Should I trust the same physician who performed the cataract surgery to remove the cortex? From the moment this surgery was performed over three months ago, I have been suffering from loss of vision, pain, cloudiness, loss of depth of color, etc. Have been on various eye drops and back and forth to ophthalmologist. After all this time, the remaining cortex was discovered. Needless to say, I am not only frightened, but extremely skeptical, since I have been suffering for such a long time. Am advised that removal must be done but that it will not help in getting my vision back.
