How Has LASIK Changed in the Last Several Years?
LASIK surgery has undergone several improvements since its approval in the United States in 1999, harnessing the latest technology to make procedures safer and more effective than ever. In fact, today’s LASIK often helps patients achieve 20/20 vision or better, all in a matter of minutes.
The LASIK surgeon accesses the deeper layers of the cornea by creating a micro-thin flap of tissue on the surface of the cornea. One method involves using a microkeratome, or hand-held spinning blade. While the microkeratome has produced good results for millions of patients over the years, the IntraLase laser has exceeded the microkeratome in both comfort and accuracy.
The IntraLase laser, also known as Blade-free LASIK or All-Laser LASIK, forms the corneal flap without a blade, increasing the accuracy and predictability of flap thickness and size. Patients who choose IntraLase (around 78%), report increased vision improvement and reduced incidence of dry eyes.
In 2002, Wavefront technology came on the scene, changing LASIK forever. The VISX WaveScan aberrometer creates a 3D map of your cornea using over 200 points of reflected light. The surgeon downloads your vision “fingerprint” to the VISX STAR S4 IR Laser System before the day of surgery. This automated transfer of data ensures more precise shaping of your cornea during the procedure, resulting in crisper, clearer vision.
Our eyes are constantly on the move, even when we don’t realize it, and they don’t keep still during surgery! In the early days of LASIK, patients were required to fixate on a light during the procedure. Today, infrared 3-D eye tracking technology detects and compensates for the smallest of eye movements, making the procedure easier for the patient and more accurate for the surgeon as the laser beam stays centered precisely over the treatment area.
Today’s LASIK patients benefit from a number of technological advancements that make the procedure as comfortable and accurate and possible. For more information on how to get the best available treatment for your eyes, call 419-289-6466 to set up an appointment.
