The Paragon Veterinary Group provides an ophthalmology
service at its Newbiggin premises. We have facilities for ocular and
intra-ocular surgery and microsurgery, including cataract extraction and
artificial lens implantation, and see cases referred from other veterinary
practices throughout Cumbria and across the North of England and South of
Scotland. The following photographs
show some of the conditions that we treat.
Face-Lift Surgery
|
Some dogs such as this Sharpei, and this Sussex Spaniel have such heavily
wrinkled faces that they are unable to open their eyes and the upper
eyelids roll downwards, rubbing on the cornea. |
|
|
|
Face-lifts have been performed to keep the eyes open and
to stop the hairs rubbing on the eye. |
|
|
Corneal surgery
|
A deep ulcer has formed in this cornea.
The cornea has ulcerated down to the bottom layer and the eye will
rupture if the ulcer deepens any more. |
 |
|
A graft of conjunctiva has been stitched into the ulcer
to protect the cornea and to fill in the defect. |
 |
|
This graft gradually is incorporated into the surface of
the eye |
 |
|
Several weeks later the graft has been trimmed to leave
a scar at the site of the ulcer. |
 |
Corneal Grafting
This example is of a cornea that has been affected by the loss of
the cells lining the inside, causing the cornea to become cloudy and to
ulcerate. |
 |
A circular blade is used to remove the
central section of the cornea. |
 |
A corneal graft from a donor animal is then
sutured in place. |
 |
|
|
This example is of a cat's cornea affected by
a dark deposit called a "sequestrum" |
 |
The affected area of the cornea is carefully
dissected off. |
 |
A section of cornea is taken from the edge of
the same eye and sutured into the defect |
 |
Cataract surgery
A cataract is an opacity of the lens.
We see these regularly in dogs, on their own, or secondary to diabetes.
It is possible to remove a cataract and to replace it with an artificial
lens. The lens in a dog’s eye is
larger than in a human eye and a dog’s eye is more sensitive than our own, but
with modern operating techniques it is now possible. There is more detail and explanatory notes on the Cataract Surgery Client Information Page.
This is a cataract prior to surgery |
 |
The cataract is removed by breaking the lens
up using a vibrating probe and aspirating the fragments.
Here the initial groove is being cut in the lens. |
 |
The lens has been split into quarters which
can then be broken up further. |
 |
The lens has been removed leaving the
surrounding capsule. |
 |
|
The artificial lens that will be inserted into
the eye. The lens can be
folded to enable it to be inserted through a small incision. |
 |
|
The lens being introduced into the eye. |
 |
|
The eye with the artificial lens in place 6 weeks
post-operatively. |
