Worried About Eye Movement During LASIK? How Modern LASIK Handles It

Human eyes rarely stay still. In fact, your eyes move even when you are asleep. A question that a lot of individuals considering specs removal often have is, “What if my eyes move during LASIK?” 

LASIK has evolved enormously over the years. Not only has it become bladeless and painless, but it also accounts for the most minor eye movements. 

While with traditional LASIK, eye surgeons had to be cautious to take care of spontaneous eye movements, modern LASIK technologies make use of cutting-edge eye-tracking technology for the same.

In this blog, we are going to delve into this revolutionary feature of modern-day LASIK. So, let’s dive in!

LASIK Evolution: Advancements Over the Years

The advent of LASIK was nothing short of a revolution for specs wearers. Now, they did not need to dream, but could actually achieve specs-free clear vision. LASIK has witnessed tremendous innovations over the years. Here are some prominent ones:

• Femtosecond lasers
• Personalisation in surgery
• Intelligent eye-tracking systems

With the introduction of the innovative 7D eye-tracking, lasers follow every roll, tilt, and micro-movement of your eye to ensure that each laser pulse is targeted with utmost precision.

What it means for the patient: Sharper vision and peace of mind during advanced LASIK/laser procedures, such as Wavelight Plus Innoveyes, SMILE Pro, and Contoura Vision.

How Eye-Tracking Enhances LASIK Precision?

Try keeping your eyes still for just 3 seconds. What did you observe? Minor involuntary movements still occur!

Such micro-movements can mean the difference between good and outstanding LASIK outcomes. It’s here that the eye-tracking feature of modern LASIK proves critical:

• The system tracks the position of your eye to the tune of hundreds of times every second. That’s far quicker than you can blink. This allows rapid correction of even the smallest movements.
• If your eye goes out of range, the laser stops right away, and starts again when the eye is precisely re-aligned.
• The technology ensures each laser pulse is delivered at the precise location in the eye. It translates into accurate results and a minimal scope of human error.

How Does Eye-Tracking Function in LASIK?

This next-gen technology boasts innovative functionality:

1. The pupil and corneal surface are scanned in real-time by infrared cameras.
2. Within milliseconds, the eye movement data goes to the laser’s computer.
3. The laser synchronises its pulses with the actual eye position. If there is any eye movement, the laser pauses, and the next pulse is not fired. 
4. Some even more advanced trackers have predictive algorithms. It means they predict the extent and direction of movement, even before it occurs, and adjust accordingly.

In short, it means the system compensates for small involuntary eye movements during treatment.

How do Patients Benefit From Advanced Eye-Tracking in Modern LASIK?

Safety

The laser only works when your eye is perfectly aligned. This minimises the scope of human error by eliminating the risk of misplaced pulses if your eye happens to move during the procedure.

Exceptional Outcomes

As eye alignment gets more accurate, results become more predictable. Patients get sharp vision, even if they have cylindrical power or an irregular cornea.

Minimal Side Effects

Modern LASIK/laser technologies, like Wavelight Plus InnovEyes, SMILE Pro, and Contoura Vision, have significantly reduced the risk of uneven correction, induced astigmatism, halos, glare, decentred ablations, etc., so that patients enjoy better vision quality.

Wider Eligibility

Even patients who were once considered unfit for LASIK, due to high specs number or specific anatomy, can also benefit from modern vision correction technologies, and get freedom from specs.

Patient Satisfaction

Patients feel relaxed as they are no longer worried about eye movement issues. Additionally, studies reveal that more patients now get 6/6 vision or even better, further enhancing patient satisfaction.

Conclusion

Modern LASIK laser technologies are equipped with cutting-edge eye-tracking systems to handle even the most minor of your eye movements. So, no longer do natural eye movements, should there be any, pose any risk.

With sophisticated eye-tracking systems in place, you can rest assured of getting the best outcomes with LASIK. Of the several latest and most advanced refractive LASIK eye surgeries, some are fast gaining popularity. 

Examples of modern LASIK laser surgeries include Wavelight Plus InnovEyes (world’s 1st fully personalised & most advanced LASIK), Contoura Vision (topography-guided LASIK), SMILE Pro (the 9-second way to clear vision), and others.
