The first human laser eye surgery was performed in 1989.
Refractive or laser surgery has been used to correct nearsightedness, farsightedness and astigmatism for close to 30 years. Over time, this medical procedure has quickly evolved with new technology being develop to make it much safer for the patient. Today, less than one percent of all recipients have serious complications from laser surgeries.
With millions of participants having the procedure done successfully, here are the major advances in laser surgery that has improved the outcome for the patient.
Medical Professionals are Discovering Wavefront Technology
Laser assisted in-situ keratomileusis (LASIK) is the most sought-after and successful surgery in medicine today. It’s a surgical procedure that changes the shape of the cornea. LASIK surgery tries to get to the middle layer of the eye, and correct the vision with a hinged flap. As doubts lessen about this procedure, the advances in LASIK surgery have come a long way in a short period of time.
Innovators have created a diagnostic tool called Wavefront Technology, which permits the doctor to build a 3D map of the eye. This highly advanced computer system allows the surgeon to diagnose and create an accurate shaping of the cornea based on the particular degree of the refractive error. The precision of this procedure has reduced the likelihood for optical aberrations such as glares and halos.
The surgeon begins the LASIK procedure by using the Wavefront Technology device to transmit a safe ray of light into the patient’s eye. The light reflects the back posterior portion of the eye, which is transmitted back to the computer. The wave of light is arranged into a unique pattern that measures both low and high aberrations. Those measurements are electronically transferred to the computer’s program that confirms where the incision is needed to repair the eye.
Technological Advancements for the Excimer Laser
The Excimer Laser was created in the late 1970s to assist surgeons in pinpointing the area of entry to the middle of the cornea. The use of lasers has revolutionized eye surgeries by gaining greater safety with each procedure that takes place.
The recent technological advancements have allowed the Excimer Laser to penetrate the cornea and remove tissue without burning or cutting the surrounding tissues. The surgeon’s main goal is to completely remove the top layer of the cornea. The laser’s light can assist with this process by removing small particles of the tissue, while reshaping the cornea and thus correcting the patient’s vision. This is accomplished by allowing the Excimer Laser access deep inside the eye to repair the retina back to properly focusing for clearer vision.
The movements of the laser are controlled by a computer, which highlights the area of the specific vision error for the patient. The Excimer Laser is equipped with an automated eye-tracking system that monitors the patient’s eye movement. Thus, this technology ensures the laser remains on target during the medical procedure. The recovery time is a bit longer than other standard laser eye surgeries.
