RxSight | Light Adjustable Lens (LAL)
This disruptive technology represents
a huge paradigm shift: It's the first
FDA-approved IOL that can be adjust-
ed after surgery. The lens is made of
a photosensitive material that
changes the shape and power of the
lens in response to ultraviolet light,
an innovation that leads to enhanced
refractive outcomes. Surgeons
implant the lens and make needed
adjustments with a light delivery
device during follow-up clinic visits
three weeks after surgery. They shine
a specific wavelength of blue light
into the eye for 30 to 45 seconds to
change the shape and prescription of
the lens. The power of the lens can
be adjusted multiple times until the
optimal refractive outcome is achieved. My early results indicate
refractive accuracy can be achieved in 95% to 98% of patients, much
higher than the 80% to 90% accuracy range surgeons typically reach
with fixed-power IOLs. This is a big development because it elimi-
nates the guesswork and pressure of predicting and promising
refractive outcomes to patients, and then having to meet their
understandable expectations of being able to see clearly without
glasses after surgery. With the LAL, we don't have to deal with the
pressure and uncertainty of trying to implant the "perfect lens." In
short, the LAL is the most accurate IOL in the world.
