medical researchers at Spire Gatwick Park Hospital, a medical
facility near Sussex in the UK, have completed the most advanced
artificial lens implant to date and have endowed patients with vision
than the most able humans traditionally have.
to get "high definition" vision begins with the
implantation of an artificial lens, using the standard procedure for
cataracts. Where as some lens implants are made of plastics
PMMA or acrylic, the high tech lenses use special light-sensitive
Several days after the implant, doctors zap the lens
with UV light, fine tuning it. Over days, the lens is carefully
tuned to overcome defects in the eye until patients have perfect
vision. A final blast of light fixes the lens in a final
The typical net result is that the recipients'
vision significantly surpasses 20/20 sight, the best vision typically
found in adults.
Dr. Bobby Qureshi is the first
ophthalmic surgeon in the UK to use the new lens and calls it "a
hugely significant development". Its not being used to
give supervision to the masses quite yet, but rather is targeting
patients with cataracts and long-sightedness, typically age-related
Describes Dr. Qureshi, "We have the
potential here to change patients' vision to how it was when they
were young. The change is so accurate that we can even make the
lens bifocal or varifocal, so as well as giving them good vision at
distance we can give them good vision for reading. They won't
need their glasses at all."
The patients are amazed at
the results. Gill Balfour, one of the first patients to receive
the lens recalls how she used to have cataracts and other vision
problems. Now the world is a richer place for her. She
comments, "It's absolutely incredible. To think it's been
tailor-made for you, matching any imperfections. It's the way
forward, isn't it?"
