Dr. Trattler, Thank you so much for replying to my question. I just have a few more, What is DLK?? Also to let you know, my husband had contacts put in last Wednesday the Dr. said he probably didn't correct him enough. The contact were taken out this morning, by the way his vision was only clear on Wednesday night. The Dr. told him that he had developed some swelling in or around the cornea. He told him to use Muro Sodium Chloride 5%. My husband said that the Dr. looked baffled to him. Which is really worrying my husband, I do feel that this dr. has gone above and beyond for us, he really seems to care and has always been there. We are just really scared. He says he will probably need an enhancement but it will have to wait a few months, which we understand in the meantime what can we do my husband is missing work and he is self employed. Can eyeglasses be prescribed for him in the meantime? Any more of your input would be greatly appreciated. Our Dr. is Bill Columbus of Trevose, PA and Wilkes-Barre, PA. Thank you again for your time.
