LASIK and Lasix sound similar, but are very different in reality. In fact, only one of them is a surgical procedure.
LASIK, or Laser Assisted In Situ Keratomileusis, is an eye surgery done to correct vision problems. During this procedure, a laser is used to alter the shape of the cornea. In most cases, the patient will not need glasses after the procedure, and is able to go about their daily life without vision correction.
LASIK is pronounced "Lay - Sick."
Lasix, also known as Furosemide, is a strong diuretic that is given by IV or as a pill. It stimulates the kidneys to produce more urine. It is often used after surgery, or to treat conditions such as congestive heart failure, acute renal insufficiency or high blood pressure.
Lasix is pronounced "Lay - Six."
