The Light Adjustable Lens is a first-of-its-kind lens implant used in patients undergoing cataract surgery and custom lens replacement. The lens prescription can be adjusted after it’s implanted in the eye by exposing it to UV light. Traditional lenses are fixed and can’t have their prescription changed. 

We’ve all had eye exams in which the doctor asks us which lens we like better “number 1 or number 2”. When your eye doctor does this test, called a “manifest refraction,” they are showing you different options and allow you to choose which one you like the best. 

Everyone gets a lens implant with cataract surgery. The Light Adjustable Lens (LAL) technology combines over 20 years of advanced optics, materials science, computing, and photochemistry technologies. The LAL uses photosensitive material that changes its shape when exposed to a specific wavelength and pattern of light.

Just like other lens implants, measurements are taken before your cataract surgery to choose the prescription of the LAL that’s best for you. However, unlike other lens implants, the LAL’s prescription is adjusted after your surgery.

A few weeks after your surgery, you’ll come back to the doctor’s office to check your prescription. This is the test in which your doctor asks you whether you like “#1 or #2 better. After your doctor finds your prescription, the light delivery device (LDD) zaps it into your lens implant.

The Light Delivery Device (LDD) shines a light on your lens implant that causes a reaction within the silicone material of the implant. The adjustment process is simple and painless and takes approximately 30 seconds to 2 minutes. You are all set!
