8:30 am to 5:30 pm. All types of ophthalmic surgery
are performed within the department including :-
- vitreo-retinal surgery
- paediatric ophthalmic surgery
- strabismus (squint) surgery
- lid surgery
- corneal surgery
- cataract surgery
- oncology surgery
- emergency surgery e.g. penetrating injury , lid
PHILOSOPHY OF CARE
We believe each individual should receive a holistic
approach to care which accounts for physical,
psychological and cultural needs.
Care should be offered in a clean, safe environment
and delivered in a courteous, professional manner.
Confidentiality, privacy and dignity should be respected
at all times through practice within the professional
code of conduct.
We aim to improve patient care through life-long
learning, audit and evidence based practice and so
offer patients informed choices in their care.
Each patient will have his or her own Named Nurse
responsible for assessing, implementing and co-
ordinating care within the multi-disciplinary team.
By use of a problem solving, patient focused approach
to care, we hope to build a partnership of care that
aims to help patients attain, maintain and restore
We aim to develop our role as educators and provide a
supportive environment where learning is encouraged
for all staff, patients and carers.
There are 13 different consultant ophthalmologists
who operate regularly in our department :
- Mr Inglesby : vitreo-retinal surgery
- Mr Fetherston : vitreo-retinal surgery
- Mr Steele : vitreo-retinal surgery
- Mr Morgan : corneal surgery
- Mr Bell : corneal surgery
- Mr Danjoux : corneal surgery
- Mr Boyce : lid and plastics surgery
- Miss Chapman : lid and plastics surgery
- Mr Tiffin : paediatric ophthalmic surgery
- Mr Gnanaraj : paediatric ophthalmic surgery
- Mr Allchin : strabismus (squint) surgery
- Mr Fraser : glaucoma surgery
- Mr Wood : ophthalmic oncology surgery
There are 2 other surgeons who specialise in fast track
- Mr Phelan
- Mr Allen
Both of these surgeons are based in Cataract
Treatment Centre and only operate in our theatres on
Most patients operated on within the department are
in-patients from Haygarth Ward and usually require a
general anaesthetic. We also perform day case surgery
under local anaesthetic, usually for patients requiring
lid surgery e.g. for an in-turning eyelid (entropian).
Some of our staff have an ophthalmic nursing
qualification and training for those who don’t is
encouraged when opportunities arise.
Research is also encouraged from both nursing and
medical staff to improve and update current practice.
Patients visiting theatre from Haygarth ward are
allocated their own primary nurse on arrival. This nurse
will then be responsible for the patients care during
their entire stay in the department. The same method
is adopted for patients attending the department as
day case patients.
Each consultant is also allocated their own primary
nurse who is responsible for co-ordinating the care and
nursing team when they operate in the department.
The consultant also liases directly with their primary
nurse to ensure all requests , equipment etc are

Emergency Alarm Calls And Numbers
Every Thursday morning the fire alarm sounds an
intermittent tone at around 11:45 am. This is the test
procedure. If this sounds at any other time it indicates
a real fire alarm and action must be taken. All doors
and windows are to be closed and remain so until the all
clear is given. A continuous tone indicates a fire alarm
in your area and immediate investigation is required
and possible evacuation of all patients, relatives and
In the event of a cardiac arrest in the department the
first action is to put out a crash call and shout for
assistance. The crash trolley is located in the recovery

The study of the eye and its associated parts.
Ophthalmology deals with diseases of the eye and their
treatment. The word ophthalmology has greek roots
derived from the greek words ophthalmos meaning eye
and logos meaning word. So its literal meaning is ‘the
science of eyes’.
Anatomy of the Eye
Ophalmology is constantly changing and updating as
research and technology offer continually improving
treatments and equipment.
During your placement you will have the opportunity to
observe a wide variety of ophthalmic surgery in our
department. The following is a brief introduction to
the types of surgery performed in this department.
A cataract is a misting or opacity of the lens. It
prevents light entering the eye properly and causes
dimness of vision and eventually blindness if left
untreated. Most cataracts are caused by the body’s
normal ageing process but occasionally are caused by
trauma, diabetes or drugs.The cataract can be removed
by an operation called phacoemulsification (see below).
The lens is broken down using ultrasonic vibrations
then aspirated. A plastic lens implanted inside the eye
(IOL - intra ocular lens) then replaces the cataract
Sutures are not usually needed and the patient can
return to a normal lifestyle immediately afterwards.
Indicated for patients with glaucoma. The operation is
performed where prophylactic treatment fails to
control the intra ocular pressure (IOP). The aqueous
fluid of the anterior chamber, in the front part of the
eye, is unable to drain sufficiently away due to a
blockage in the drainage channel, the trabecular
meshwork, located at the junction between the sclera
and the cornea.
Trabeculectomy involves creating a thin scleral flap and
internally cutting two small holes, one in the iris (an
iridectomy) and the other in the drainage channel,
usually at 12 o’clock to be less noticeable under the eye
lid. This allows the aqueous fluid to flow freely and
gradually be absorbed by the bloodstream and so
lowering the intra ocular pressure.
A ptosis is a drooping of the upper lid. It can be caused
- Abnormal weight on the lid due to oedema, tumour
- trauma or disease to the muscle
- paralysis of nerves supplying the upper lid
- congenital causes
A ptosis can be corrected by lid surgery during which
the levator muscle in the lid is resected.
Is a turning in over of the eyelid due to weakness of
the lid retractors (the muscles which open and close
the eyelids). Usually occurs in the lower eye id causing
eye to water and eyelashes to rub against the cornea
causing pain and discomfort. There are many different
operations to correct entropian but all usually involve
removing part of the eyelid therefore tightening the
retractor muscle and shortening the lid.
Is a turning out over of the eyelid due to a weakness of
the orbicularis muscle. Usually occurs in the lower eye
lid and causes the eye to water constantly because the
drainage hole (punctum) is not in the correct position.
The most common operation is to shorten the eyelid
and to enlarge the punctum to reduce watering.
Lid Lesions - Removal
Usually performed to remove a lesion for diagnostic
purposes. If results indicate a carcinoma further
surgery will be required to remove it and re-construct
the eyelid. Some lid lesions may also be removed for
The Meibomian glands are found in the eyelids and
produce a sebaceous substance, which creates the oily
layer of the tear film. A chalazion occurs when one of
the Meibomian glands swell due to a blockage of its
If the swelling does not subside the chalazion can be
removed by incision and curettage. A clamp is placed on
around the chalazion and the eyelid everted. A small
incision is made and the contents scooped out using a
curette. The clamp is then removed and some anti-
biotic ointment and a firm pad are applied.
Removal of the contents of the eye, usually after an
infection has left the eye blind. A small amount of eye
movement is retained after this surgery giving a more
cosmetically pleasing result.
Removal of the whole eyeball leaving the extra ocular
muscles. The socket is fitted with a conformer to
enable a good cosmetic result with a prosthesis (fitted
at a later date). It is often performed as a last stage
of treatment for a painful, blind eye following
Epiphora, or watery eyes, occurs because of a blockage
in the normal lacrimal drainage system, which impairs
normal tear channelling into the nasal cavity.
Recurrent infection or dacryocystitis may occur as a
result of stagnation. DCR may alleviate symptoms and
involves surgical creation of a new passage of drainage
for tears into the nasal cavity.
Vitrectomy and Detachment Surgery
These operations are performed for patients who have
problems with their retina often associated with
diabetes, short-sightedness (myopia) or trauma. The
operations are often intricate and lengthy procedures.
Vitrectomy (internal approach) involves removing the
jelly part of the eye (vitreous) and replacing it with a
fluid containing minerals and salts and is about the
same consistency as the aqueous fluid of the anterior
chamber. Microsurgery is then performed to attempt
to rectify the specific problem such as retinal holes,
tears or membranes.
Detachment (external approach) is performed on the
outside of the eye (sclera) and involves suturing a
silicone explant onto the sclera to create an
indentation of the detached area of retina. A freezing
process (cryotherapy) is then applied over the sclera
to induce an inflammation over the retinal problem. The
inflammation will gradually subside taking the retina
back to its normal position and up against the
indentation of the explant.
Occasionally a gas bubble is (SF6 or C3F8) mixed with
filtered air is injected into the eye to tamponade
problem retinal areas. The gas bubble will expand a
little inside the eye and push up against the retina and
help keep it in place. The gas bubble is gradually
absorbed. Patients may need to posture post-
operatively to help with the success of the operation
i.e. lie in a certain position so gas bubble tamponades
the right area of retina. The posturing can be said to
be as important as the surgery itself.
A corneal graft is a transplant operation involving
removal of the central part of the cornea and its
replacement with a cornea from a donor. The donor
cornea comes from someone has expressed a wish that
their corneas be used to help someone else see after
their death. The donor cornea is sutured to the host
using either a series of interrupted sutures or one
continuous suture. The sutures may be left in place for
up to two years. Although rare, corneal rejection is a
post op complication and can occur even years after
surgery. Rejection occurs most commonly in the first
year after surgery.
Pre-admission Assessment Clinic
Almost all elected patients are assessed prior to
admission within one month of their surgery date,
investigations are undertaken, eg tonometry,
venepuncture, electrocardiograph, focimetry. Physical
and social needs are taken into consideration and social
services, occupational therapists or district nurses may
be required for input on discharge from hospital.
These services can be organised before admission,.
The patient can receive information about their
forthcoming surgery here.
Specialised nurse-led clinics are undertaken here, eg
blood monitoring, oculoplastics.
Patients attend as outpatients. Consultant
Ophthalmologists also hold regular clinics here.
Cataract Treatment Centre
Patients are assessed prior to day case surgery, nurses
prepare the patient for surgery and surgery such as
cataracts under local anaesthetic and other eye
operations are carried out and the patient is usually
discharged the same day.
Nurses carry out a post-operative telephone
assessment on the first post-operative day.
Patients are also seen as outpatients by Consultants
and listed for surgery as well as reviewed one-two
Main Theatre / Day Case Unit
Again, patients are assessed prior to day case surgery.
Patients undergo surgery for all manner of eye
problems under general and local anaesthetic, eg
vitrectomy, squints, cataracts, trabeculectomies.
Nurses carry out a post-operative telephone
assessment on the first post-operative day.
Accident and Emergency
Patients attending the department are triaged into one
of three categories.
1 = ocular emergency
2 = urgent
3 = non-urgent
The patient will be seen by the nurse practitioner, the
nurse consultant, or the doctor, who can carry out the
ocular examination and treatment. Conditions can
include chemical injury, embedded corneal foreign
body, arc eyes, eyelid lacerations, penetrating injuries,
conjunctivitis etc. A minor operating theatre exists
for small repairs/excision of chalazions and injection
of botulinum toxin injections.
Ocular ultrasound is undertaken, as well as laser
treatment and fluorescein angiograms on in-patients
and out-patients as needed.
Medical physics investigations can be done also.
The glaucoma unit also carries out tests here
Excimer Laser Unit
Patients undergo refractive surgery here carried out
by the Corneal Consultants.
Visual acuity is checked at each visit and doctor in the
clinic sees the patient. Adult and paediatric clinics are
