The LASIK Process

Your Free LASIK Consultation

Our LASIK process begins with a complimentary information-gathering session at our Mechanicsburg office where you can get the facts about LASIK and we can learn about your goals and expectations for vision correction. We will address your concerns about the procedure and do some preliminary testing to confirm whether LASIK is the solution for you. This free consultation is your opportunity to meet with Dr. Armesto and ask questions about the procedure.

Refractive Surgery Evaluation

This comprehensive exam is to confirm that your eyes are healthy and to determine your degree of nearsightedness, farsightedness, or astigmatism. A dilated eye exam and several specialized tests are performed. We evaluate the curvature and optics of your eyes, analyze its surface and health of the tear film for signs of dryness, and measure the corneal thickness and pupil dynamics.   Your eyes will be thoroughly studied inside and out to ensure there are no issues that might need to be addressed before committing to surgery.  This detailed examination will also give Dr. Armesto the opportunity to learn more about you, your life, and your vision needs.  The information from this examination will give Dr. Armesto what he needs to create your optimal result.

Laser Eye Surgery

LASIK is refractive eye surgery in which a laser is used to reshape the cornea and improve vision. This painless procedure lasts just a few minutes, and your whole appointment shouldn’t be much longer than an hour. Your eye is numbed using “eye drop” anesthesia, and an eyelid holder is placed between your eyelids to prevent you from blinking. Dr. Armesto uses advanced Femtosecond laser technology to create a tiny flap that reveals your cornea. A second computer-controlled excimer laser is then used to precisely correct your exact, unique prescription.  This all-laser technique provides superior precision and safety.  In some cases, a corneal flap may not be appropriate.  In such instances, Dr. Armesto will use another laser procedure called Advanced Surface Ablation without the corneal flap.

LASIK for Nearsightedness, Farsightedness & Astigmatism

To treat nearsightedness, the cornea must be made flatter.  This is accomplished by removing tissue from the center of the cornea. You will be asked to look directly at a target light while the laser reshapes the cornea, usually in less than a minute. For farsightedness, the central cornea must be made steeper.  This is accomplished by directing the laser beam to remove tissue from around this area. To treat astigmatism, the cornea must be made more spherical.  By changing the pattern of the beam, tissue is removed in one direction more than the other.  Each eye for every patient has its own unique optics, like a fingerprint, which is digitally scanned into the laser’s computer.

With LASIK, as soon as the laser dose in delivered, the protective flap is carefully folded back in place where it bonds securely without the need for stitches. After LASIK, some patients report a slight discomfort that usually goes away within a few hours. For patients receiving Advanced Surface Ablation, the doctor will place a protective bandage contact lens on the eye to improve comfort during the 3-to-5-day healing process. The risk of side effects are less than 1% with properly selected patients, but it is still very important that you keep all your postoperative appointments.
