Cornea Donation
The gift of sight is precious.
More than 3,600 people have their sight restored by cornea transplants in the
UK every year.
Transplant
·
Cornea transplants are successful sight-saving
operations, with 93% of grafts functioning after one year. By five years, 72%
of grafts are still functioning and many will continue for many more years
after that
·
The first successful cornea transplant was reported
in Olmütz, Moravia, (now the Czech Republic) on 7 December 1905
·
Around 2,000 people donate their corneas after their death, but there is
still a shortage in the UK – more people could benefit from a sight-saving
transplants if more corneas were available
·
More than 44,000 cornea transplants have been
recorded on the National Transplant Database since the Corneal Transplant
Service began in 1983
·
Both old and young patients benefit from cornea
transplants. The youngest person to receive a cornea transplant was just a few
days old. The oldest was 104
·
The oldest recorded cornea donor was 103
·
People of all ages can donate
corneas and about 65% of cornea-only donors are over 60 years old
·
Corneas from very young donors (under three years)
are needed very rarely
·
Over half (52%) of all cornea transplant recipients
are aged 60-89; nearly a quarter are patients in their 70s; and 3% of
recipients are under 19 years old
·
The Corneal Transplant Service (CTS) was launched
to help distribute corneas around the country so that all patients who needed a
transplant could benefit
·
90% of transplants use corneas stored in the CTS
eye banks in Bristol and Manchester, which use special techniques to store the
corneas for up to four weeks. Corneas are sent from other eye banks and
hospitals throughout the UK for storage and subsequent distribution to more
than 200 cornea transplant units
·
Many more people could be cornea
donors than general organ donors. Unlike most other organs, corneas can be
donated up to 24 hours after death. You do not have to die in hospital to
donate your corneas but the retrieval service is usually provided by a major
hospital
·
There are now eight hospitals around the country
with full time eye retrieval staff funded by UK Transplant, aiming to maintain
or increase supplies of corneas for transplant
About the cornea
·
The cornea is the clear tissue at the front of the
eye that lets in light and helps focus it on the retina so that we can see
·
Disease or injury can make the cornea cloudy or
distorted in shape, causing loss of vision
·
A cornea transplant replaces diseased corneal
tissue with a disc of healthy tissue from a donor
·
The procedure is straightforward and usually takes
about an hour to complete
·
There is no upper age limit to cornea donation –
many successful transplants have been performed with corneas from donors in
their 90s
·
The most common reason for cornea
transplantation in younger people is a condition called Keratoconus where the
cornea becomes misshapen and cone-shaped
·
In older people, age-related or inherited
conditions may lead to cloudiness of the cornea
