Even when we think our eyes are perfectly still, they are constantly making small movements. And while this might not be a hindrance in your everyday life, it can be a hassle during specs removal surgeries.
Years ago, LASIK surgeons had to rely largely on their skills to deal with the spontaneous movements of a patient’s eye. However, with newer technological advancements today, you can rest assured that the laser keeps pace with every little movement your eye makes.
If you plan on undergoing LASIK eye surgery, it is crucial to understand how advanced LASIK tracking systems make the surgery a safer and more precise procedure.
How Has LASIK Evolved Over Time?
When LASIK eye surgery made its debut, it was a game-changing revolution in the field of eye care. But conventional LASIK technologies, while transformative, largely depended on manual techniques.
However, today’s LASIK has completely changed the specs removal landscape with the introduction of femtosecond lasers, eye-tracking systems, AI-based surgical planning, wavefront & topography-guided systems, and much more. These new advancements (for example, in Wavelight Plus InnovEyes, SMILE Pro, Contoura Vision, etc.) ensure higher precision, fewer side effects, and sharper vision.
Why Does Eye Tracking Matter in LASIK Surgery?
Even when we try to keep our eyes perfectly still, they make tiny involuntary movements known as microsaccades. These movements can have an impact on the results of LASIK. This is where eye-tracking comes into play – by tracking every tiny movement of the eye, this advanced feature ensures the laser is applied precisely only at the desired area, ensuring consistent and accurate results.
- The system tracks each eye’s movements multiple times (hundreds to thousands) per second, quicker than you can even blink.
- In the off chance that your eye strays out of the laser’s range, the beams immediately pause and only resume once the eye is adequately realigned.
- This reduces the scope of human error and yields uniform results, providing excellent visual clarity.
How Eye-Tracking Really Works During LASIK Surgery
It may sound complex, but the tech behind eye-tracking systems is actually quite simple yet robust:
- Real-time corneal and pupil scanning through infrared cameras.
- All movement data of the eye is sent to the laser’s software within milliseconds.
- The laser then syncs its application with the eye’s real-time position. If a blink of harsh movement is detected, the laser automatically pauses.
- Some advanced systems use predictive algorithms to anticipate eye movement patterns and compensate in real time for tiny shifts during surgery. They can forecast the extent and direction of a movement before it even occurs, providing enhanced accuracy when you breathe, blink, or shift your eye.
Types of Eye-Tracking in LASIK Eye Surgery:
There are many types of eye-tracking systems, but the most commonly found are:
- Infrared-based trackers
- Video-based trackers
- Electromagnetic trackers
Benefits of Eye-Tracking in LASIK
Enhanced Safety
Tracking makes sure that laser energy is being applied only when the eye is ideally aligned. This advanced technology ensures there’s next to no risk of misplaced laser pulses, eliminating the prospect of over- or undercorrection.
Better Results
Because this technology ensures that the laser pulses are being applied only to the desired area, the visual results of LASIK are more accurate, consistent, and sharp (even for people with astigmatism or higher-order corneal aberrations).
Smooth Surgical Experience
Knowing that the system automatically adjusts to the eye’s natural, involuntary movements generally helps patients relax, especially if they’re nervous about keeping their eyes perfectly still.
Eye-tracking technology has made LASIK eye surgery a much safer and more precise procedure. So if you or a loved one is planning on getting LASIK, you can rest assured once you explore the wide range of advanced specs removal technologies at Sohana Hospital.
