LASIK and Lasix sound similar, and they are even almost identical in spelling, but these two things are very different. In fact, while they are both used in healthcare, they aren't even remotely related, except that they sound very much alike. Luckily, it would be nearly impossible to confuse one for the other and accidentally get Lasix when you wanted LASIK or vice versa.

LASIK is a type of surgery, Lasix is a diuretic - a medication that makes you urinate.

LASIK Surgery

LASIK, or Laser Assisted In Situ Keratomileusis, is an eye surgery done to correct vision problems that are corrected with glasses. During this procedure, a laser is used to alter the shape of the cornea. In most cases, the patient will not need glasses or contact lenses after the procedure, and is able to go about their daily life without vision correction.

LASIK is pronounced "Lay - Sick."

Lasix Medication

Lasix, also known as Furosemide, is a strong diuretic that is given by IV or as a pill. This medication is frequently used after surgery. 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."
