The Future of Surgery

Posted Posted in Health and Medicine: General

By Nicole Strossman, Biochemistry and Molecular Biology, ’17 What do you picture when you think about surgery? Most likely, you imagine a person having their body cut open, and then a surgeon performing what is necessary to fix the problem, whether that be removing a damaged organ or tissue, repairing damages internally, or performing some other procedure. In all of these cases, it is expected that the doctor makes a cut large enough so that he or she can see what is inside of the body and operates. However, a new method of surgery takes a radically different approach. Laparoscopic surgery, also called minimally invasive surgery, Band-Aid surgery, or keyhole surgery, is a relatively new surgical technique that is revolutionizing the surgical field. Traditionally, surgery is performed by making a large incision in order to directly view and operate on the tissues, organs, and other structures of interest inside of […]

By David Ivanov, Biochemistry and Molecular Biology, 2015 LASIK, or laser-assisted in situ keratomileusis, is a surgical procedure commonly used to correct for visual defects or lack of visual clarity. Commonly referred to as laser eye surgery, LASIK is a type of surgery that is used to alleviate visual loss associated with common defects of the eye, such as myopia (nearsightedness), hypermetropia (farsightedness), and astigmatism. Astigmatism, like near and far-sightedness, can be caused by the irregularity in shape of the cornea that leads to blurred vision. For all three cases, corneal remodeling via LASIK can be performed (Thomson, 2015). The cornea is the outermost layer of the eye, the transparent part that one can touch, and upon which contact lenses are placed. It is responsible for most of the focusing power, and thus is a common culprit in visual defects of the eye. The cornea focuses the light reflected into […]
