An FDA study showed that approximately twice as many patients could see 20/20 or better after their final prescription was “written” onto the lens, compared to standard IOLs
You are Unique, and so are your Eyes
Lens Calculations
Every eye undergoing cataract surgery needs an intraocular lens (IOL) with a unique power. Special eye measurements are used to calculate the unique power of the lens.
As you might expect, these prediction formulas are not perfectly accurate for every patient because of individual differences.
Previous Eye Surgery and Special Eyes
Certain factors may make IOL power selection much less accurate, such as a history of prior refractive surgery like LASIK, PRK, or RK (radial keratotomy) .
Also, because of genetic variants, some calculations may have low predictability, like in large or small eyes.
This can lead to refractive surprises after cataract surgery
A Light-Adjustable Lens Provides the Reassurance that the Vision Can Be Customized After Surgery
A light-adjustable lens allows us to fine-tune based on real measurements after surgery, not on calculations.
Also, those who want significant independence from glasses with Blended Vision —using one eye for distance and the other for near — will enjoy the precision of this lens, because of its ability to fine-tune each eye for its optimal target.

How does the LAL actually work?
The power of any lens depend on it’s shape and curvature. Traditionally, intraocular lenses are made from materials that cannot be modified after the lens is manufactured.
The LAL is different: it contains light-sensitive molecules that can be adjusted by an external UV light beam to fine-tune the shape and power of the IOL without requiring additional surgery. The lens can be adjusted to treat astigmatism, nearsightedness, or farsightedness.

What to expect after surgery
The cataract surgery procedure is basically the same as with any other lens. The magic begins a few weeks after, once your eye has healed and your vision had stabilized.
The lens adjustments are performed with a Light-Delivering Device in our office. We will take some measurements of your eye(s) and then your eye(s) will be dilated. The treatments are painless and take about 5 minutes. It is possible to make up to 3 adjustments, although most eyes require only one.
When the result has been optimized, a final “lock-in” treatment is performed, after which the lens can no longer change or be adjusted. After lock-in, no extra protection is needed for sunlight or UV light.
