Corvis ST Measures Corneal Strength with Just a Puff of Air
This technology is essential to determine whether your eyes are ready for procedures like LASIK or SMILE Pro. Let’s see how it works.
Eye Exam Without Touching? How Is That Possible?
Ever imagined your eyes being examined without anything touching them—just a gentle puff of air and a super-fast camera?
It’s not magic.
It’s called Corvis ST, a new standard in pre-screening for vision correction procedures like LASIK or SMILE Pro.
What Is Corvis ST?
Corvis ST is a device that measures the biomechanical properties of the cornea—in other words, its strength and ability to maintain shape under pressure.
Think of your cornea as the front window of your eye.
If that window is too flexible, vision correction procedures could be risky.
Corvis ST helps your doctor determine if your cornea is:
-
Strong enough?
-
Too flexible?
How Does Corvis ST Actually Work?
Let’s imagine you’re sitting comfortably in front of the device, then:
-
Corvis ST sends a soft puff of air to your eye.
-
Your cornea moves slightly in response.
-
A high-speed camera inside the device captures the movement—over 4,000 frames per second!
-
From the video, the device calculates:
-
How fast your cornea returns to its original shape
-
How far it bends
-
How stiff or flexible it is
-
-
The results appear instantly in graphs and numbers.
The entire procedure takes less than 10 seconds, and you won’t feel any pain at all.
Why Is This So Important Before LASIK or SMILE Pro?
Vision correction procedures like LASIK or SMILE Pro reshape and thin your cornea to improve your eyesight.
But if your cornea is too thin or too flexible, the procedure should not be performed.
With Corvis ST, your doctor can say:
-
“You’re good to go for LASIK or SMILE Pro!”
-
“Not yet—your cornea isn’t eligible for LASIK or SMILE Pro.”
How Is It Different from a Regular Eye Exam?
Typical eye exams only measure:
-
Your glasses prescription (minus, cylinder)
-
Corneal thickness
But Corvis ST provides:
-
Detailed insight into your cornea’s readiness for LASIK or SMILE Pro
-
Assessment of long-term risks like ectasia or early signs of keratoconus
Who Should Get Checked with Corvis ST?
Anyone planning to undergo:
-
LASIK
-
Presbyond
-
SMILE Pro
-
SMILE Pro for Hyperopia
-
PRK
-
Or those with high astigmatism, or a family history of keratoconus
In Summary: Smart Tech That Keeps Your Eyes Safe
Corvis ST is like a high-tech detective that helps your eye doctor decide whether your eyes are suitable for LASIK or SMILE Pro.
It’s fast, safe, and helps prevent long-term risks.
Your eyes are precious. Don’t take any chances without knowing their true condition
