You should first get the extent of opacity in your cornea
assessed by a specialist. If it is covering the central area of your cornea, you should get your pupil dilated and get an examination done with stenopic slit. If there is improvement in the vision, you should go for a optical iredectomy. If there is no improvement in the vision with stenopic slit with a dilated pupil, keratoplasty may be the answer to the problem. For all this you need to visit a eye surgeon and get the needful done.
