General Purpose: To Inform
Specific Goal: To inform my audience about LASIK surgery and the risks and benefits of associated with it.
Thesis Statement: LASIK eye surgery can be beneficial to some individuals. There are however, complications that can come from having the surgery done. I will explain what LASIK surgery is and explore the benefits and risks associated with LASIK surgery.
Preview: I will explain what is done when you have LASIK surgery and inform you of the risks and benefits associated with having it done.
I. Do you wear glasses or contacts? Have you ever thought about having LASIK surgery to correct your vision problem?
II. LASIK surgery is the newest and fastest growing tool eye surgeons now use to correct visual disturbances such as farsightedness, nearsightedness, and astigmatism.
III. LASIK surgery is a major decision for any individual. After doing some research on the internet I discovered the risks and benefits that are associated with the procedure.
I. What does LASIK stand for?
a. LASIK stands for laser in situ keratomileusis, or in simpler terms, using a laser underneath a corneal flap to reshape the cornea. (MedicineNet.com, 2010)
II. What happens during LASIK surgery?
b. During LASIK surgery a patient reclines under a surgical device called an excimer laser. c. First eye drops are administered to numb the eye, then an eyelid holder is placed between the eyelids to keep them open and prevent the patient from blinking. A suction ring placed on the eye lifts and flattens the cornea and helps keep the eye from moving. d. Once the cornea is flattened, a flap of corneal tissue is created using a microsurgical device. The corneal flap is lifted and folded back. Then the laser, preprogrammed with the patients with patient’s unique eye measurements, is centered above the eye. e. The surgeon checks to make sure the laser is position correctly, then the patient looks at a pinpoint light while the laser sculpts the corneal tissue. f. The surgeon then places the flap back into position and smoothes the edges. The corneal flap sticks to the main cornea and stitches are not needed. g. The patient is then allowed to have someone else drive them home. To help protect the cornea the surgeon places a transparent shield over the eyes and to help remind the patient not to rub them. h. It may take three to six months after surgery for the patient to see improvements in their vision. (allaboutvision.com)
III. Who is right for LASIK surgery
i. The ideal candidate is over the age of 18 and has had a stable corrective prescription for the last two years. j. The patient must have sufficient corneal thickness. k. Do not suffer from any disease, such as lupus or rheumatoid arthritis, which would reduce the effectiveness of the surgery or my ability to heal properly and quickly. l. Am I comfortable with possibility that I may have to have a second surgery or I might still need to wear glasses for certain activities such as reading or driving. (eyesurgeryeducation.com)
IV. Types of LASIK surgery
m. IntraLase LASIK
i. No blade is used. Instead the flap is cut using computer guided, infrared laser energy to cut the flap. After the flap has been cut the rest of the procedure is the same as traditional LASIK surgery. n. Wavefront LASIK
ii. Custom surgery that involves a 3-D assessment of how your eye functions. iii. It provides more precise LASIK correction.
iv. Not all LASIK surgeons provide this type of LASIK correction so you will have to do more research. o. Epi-LASIK
v. Combines LASIK surgery procedures with non-traditional procedures. vi. Ideal for patient with thin corneas.
p. Monovision LASIK
