Glasses fog up. Contacts dry out. If you have a strong prescription and astigmatism, you know the pain. Blurry lines. Streaky lights at night. Endless squinting. Wavelight Plus can fix both problems at once. It uses more precise tools than older lasers.
Here is what makes Wavelight Plus different. Here is why it works so well for high power and astigmatism. And here is what you can expect.

Can Wavelight Plus Treat High Eye Power and Astigmatism?
What is Wavelight Plus?
Wavelight Plus is a fully personalized LASIK treatment. It uses Alcon's Wavelight EX500 laser. This is the same laser used in older LASIK treatments. But it adds a new tool. It is called the INNOVEYES SightMap system. When combined, it creates a full optical picture of the structure of your eye.
Older LASIK only measured the surface of the eye. Wavelight Plus deeply scans the cornea. It is far more precise and tailored for every unique cornea it comes across. The process is
- It maps the eye
- The corneal lens is examined
- The light ray entry through the entire eye is outlined
- A digital eye twin is created
- The model captures more than 100,000 data points on the eye
- Finally, an eye map is made
The treatment is suited to your eye needs and requirements with high precision. Wavelight Plus for high power is recommended for patients struggling with astigmatism.
Why High Power Prescriptions Need Special Care
Strong prescriptions bring extra challenges. Old lasers can struggle with high myopia. Results can vary more than patients hope. Wavelight Plus changes that. Wavelight Plus solves this issue in 2 ways
- A fast laser at 500 Hz is used, keeping the treatment time short. Shorter treatment time means less time for your eye to shift and move during the surgery.
- An eye tracker that runs at 1050 Hz, which follows every tiny movement in real time, locking in on the target.
How Does LASIK for Astigmatism Work With Wavelight Plus Technology?
How it Prevents Astigmatism
Astigmatism happens because your cornea curves unevenly. This shape scatters light instead of focusing it. That is why straight lines can look wavy or doubled. Standard LASIK treats astigmatism well. Wavelight Plus does more.
Wavelight Plus resolves this issue by using ray-tracing technology with precision. This method traces how light rays enter and travel through your entire eye. It takes into account factors like your natural lens and other hidden optical quirks.
This full eye view allows the laser to correct astigmatism that is well-suited to your unique vision. Clinical studies are backing it up, with studies showing that Wavelight Plus surgeries produce a few higher-order irregularities when compared to older systems, which is a great improvement.
Higher-order irregularities include tiny optical flaws that cause glares, halos, hazes, and poor night vision. LASIK for astigmatism with Wavelight Plus removes these tiny flaws and errors, guaranteeing you better vision and overall clarity, even in dim light.
The Numbers Behind It
So, to what extent can Wavelight Plus technology correct your vision?
Numbers matter more than marketing claims. Here is what one real study found. The US-FDA-approved WaveLight EX500 excimer laser is paired with SightMap.
It covers a range of spherical and astigmatic corrections with specific sets limited to cylindrical power at the spectacle plane. These numbers matter because they open doors and allow patients to obtain surgery.
If you were denied LASIK because your eye power was too strong, then now it is time for you to ask your eye surgeon about Wavelight Plus technology.
Results Given
Outcomes with Wavelight Plus Vision correction are always better, stronger, and positive. Clinical study data show that every patient in an FDA trial reached 20/20 vision.
Many patients even reported far better clarity in their vision than anticipated. A majority of the chunk recorded 20/16, with half reaching 20/12.5, which is a level of sharpness beyond typically accepted “perfect” vision.
This is all due to the personalized and tailored approach showcased by Wavelight Plus. Since the laser adapts to your eye’s exact map, it is not a one-trick pony approach. It builds a very in-depth treatment plan based on your specific optical fingerprint.
During the Procedure
Wavelight Plus is quite similar to LASIK, but only with a few added upgrades in it.
SiteMap Usage
- Your eye surgeon will use this device to scan your eye. This step gathers detailed data about your cornea, lens, and overall optical system. This map helps build a perfectly built cornea treatment plan.
Thin Flap Creation
- On the day of your surgery, a thin flap will be created on your cornea by the doctor. The laser beam will reshape the tissue underneath it. This all happens according to the customised eye treatment plan made using the SiteMap. Finally, your surgeon will reposition the corneal flap, which naturally seals in with the eye without any stitches.
Very Quick
- The whole procedure takes about 10-15 minutes per eye. This also includes the prep time and the positioning. But your total time in the surgical room will take around 20-30 mins, maximum. Patients also spend one to two hours at the office, counting pre-op and post-op steps.
- At least 18 years old and above, as the eyes are beyond the developmental stage.
- Stable vision for a year from pre-surgery.
- Eye power needs to fall under the treatable range for myopia and astigmatism.
- Recovery moves more quickly than most people expect. Many patients notice sharper vision within hours. The clarity keeps improving over the following day and weeks.
- You will need to use the prescribed eye drops as recommended by your eye doctor. Avoid eye-straining activities like contact sports and blue light screens.
- If you are concerned about durability, then you will be relieved to know that the changes hold up.
- The corneal reshaping is permanent. So, you will not experience vision regression, unlike that with untreated refractive error.
- But eyes, like any other body organ, age. So, roughly 10-15% patients require a touch-up enhancement within ten years. Natural age is responsible for this, not because the surgery failed with your eye condition.
