Cataract Surgery, South Canterbury Eye Clinic

During 2016, Leah's eyes were painful, so she visited her Fairlie GP who said she had cataracts & needed to see an ophthalmologist. There was a long waiting list for ophthalmologist appointments at Timaru.

Breadwinner teacher Leah needed good eyes at Lake Tekapo School, St Joseph's School, Fairlie, working with private students at Fairlie & lecturing Specific Learning Difficulties topics at Seabrook Mackenzie Centre, Christchurch.

Leah's 3 year teaching contract ended at Lake Tekapo School, so at year's end we moved to Pleasant Point, after Leah got a Resource Teacher Literacy post at Timaru. Leah would need good eyes to commute daily by car from Pleasant Point to Timaru. Her new job also needed good driving eyes to South Cantebury schools from Timaru to Waimati southwards, Peel Forest northwards & Twizel westwards, requiring her regularly visiting & advising 40+ South Canterbury schools.

Wed 15.02.17. South Canterbury Eye Clinic appointment: Over 2 hours, Leah was seen & tested by 2 ophthalmologist nurses & an ophthalmologist to assess her for placement on the 4 month waiting list for cataract surgery at Timaru Hospital. Leah was told NZ state would pay $3000 for cataract surgery in one eye.

If Leah wanted cataract surgery in the other eye she would have to go through the whole bureaucratic nonsense again, seeing staff at South Canterbury Eye Clinic again to get on another waiting list for cataract surgery in her other eye. Or if we had the money, opt for cataract surgery by a private surgeon & pay his private fee. Meanwhile without cataract surgery on both eyes simultaneously, Leah's sight would be marginal & glasses defunct, while waiting for surgeries in separate eyes several months apart.

South Canterbury Eye Clinic gave Leah a handout - CATARACT SURGERY INFORMATION - PUBLIC which read:

Cataract is a clouding of the natural lens, the part of the eye responsible for focusing light and helping to produce clear, sharp images. The lens is contained in a capsule within the eye. Over time the lens changes, making images blurred or fuzzy.

For most people, cataracts are a natural result of aging but can also be caused by certain medications or injury to the eye.

In cataract surgery, the clouded natural lens is removed and, in most cases, a permanent intraocular lens (IOL) implant replaces the natural lens.

Eye tests at the Eye Clinic

The nurse puts drops into your eyes to make the pupils bigger [Leah's pupils became as wide as blackberries] so that the Ophthalmologist can examine the eye. He can advise you of possible risks and outcome you can expect from the surgery. He will get you to sign a consent form for surgery.

The nurse checks both your distance and reading vision and questions you to determine how your reduced vision is impacting on your life. Your eyes are measured on two different machines to obtain the exact lens strength required. You may also have had the operation explained to you and have been given written information. The nurse will also ask you questions about any other health issues, medicines you may be using, medication allergies and whether you have been in hospital before.

The office staff will get you to sign a form to give your permission to put your name on the waiting list. The office staff will get contact details for you and your next of kin for the Hospital.

You will be given a prescription for the post-operative eye drops, Please get this filled when you get your surgery date. Inform staff if help is required for the post-operative drops.

You have been placed on the list for cataract surgery. The Hospital Booking Office staff will notify you of the date when your surgery is scheduled. You will be sent admission information. Read the hospital information and the fact sheet and keep them.

If you take Warfarin you will be asked to have a Blood Test prior to surgery. Cataract surgery is usually done as a day case meaning you will be discharged from the hospital on the same day as your surgery.

Smoking

You are advised to stop smoking at least six weeks before your operation as smoking causes anaesthetic complications, can damage the eye's blood supply and impairs the body's healing ability. Eye Clinic or Hospital staff can refer you onto quit line. Please contact them prior to admission if you wish to take advantage o this service.

Discharge planning

Arrange for someone to take you to and from the hospital and to the post-operative appointment. You won't be able to drive yourself. You should either arrange to stay with someone, or have someone stay with you on the first night in case of unanticipated problems. [Like what?]

Food

* You will be advised by the Hospital or Ophthalmologist, but normally if your surgery is under local anaesthetic you will eat a light meal prior to admission.
* If you are having a General Anaesthetic or sedation you will receive fasting instructions from the Hospital. / Anaesthetist.
* Take your normal prescribed medication as usual unless told otherwise. Diuretics (water pills, e.g. Furosemide) may be omitted. You will be advised if there is any alteration for diabetic medication. Remember to take all your medications with you. The hospital will advise you about Warfarin according to INR results.

Do not wear any make-up (other than moisturiser) or nail polish.

On the day of your surgery

Go to the Day Patients on Level 4 of the Hospital. You will be seen by the Ophthalmologist performing your operation; you will sign the Consent Form, if it has not been signed, for the operation and a mark is placed over the operative eye.

You will also be assessed by the anaesthetist; and asked to sign Consent for the Anaesthetic. The Anaesthetist decides the type pf anaesthetic most appropriate for you - local anaesthetic - numbing of the eye before you have your operation, you may require light sedation or a general anaesthetic.

About one hour before your operation, drops will be placed in your eye to dilate the pupil. [Blackberry wide again]. Once you are taken to the operating theatre, other drops will be placed in your eye to numb the surface, and any other Local Anaesthetic will be given before the operation. If you are having a general anaesthetic you may not require these numbing drops. You will be asked your details and the operation you are having several times during your hospital stay - this is called 'Safe site surgery' and is recommended by the WHO (World Health Organisation).

During the operation

[Two pics of a plastic lens being folded into place with a surgical instrument behind the iris. Caption: Inserting the new lens].

The theatre nurses will make you comfortable on the theatre table.

You will be given a constant supply of oxygen during surgery and the clear, light, plastic, sterile drape will be lifted off your mouth and nose.

The procedure will be explained to you and you will be asked to warn them if you need to move or speak. It is important that you don't move any part of your body or talk. The ophthalmologist has instruments inside your eye and any unexpected movement you make could therefore result in damage to your eye. [Why not use a head brace?] He can usually stop and remove his instruments from your eye, or let you know when it is safe for you to move or cough.

The actual operation usually takes about 10-20 minutes per eye. so that is the only time you will need to be still for.

The time from when you arrive at hospital to the end of your surgery, will be subject to differing circumstances which cannot be controlled. [Like what?]

After the operation

You will return to the day ward with a cover over the eye which stays in place until the next day. After a light snack you will be free to leave.

The nurse will give you:

* an instruction sheet with contact phone numbers (in case of problems). [Like what?]
* eye drops should be collected prior to returning home, so the eye drop regime can be commenced when the cover is removed the next day - these drops will help settle inflammation.
* if the eye is uncomfortable, take Panadol (not Asprin or Disprin) [Why?] to relieve the discomfort.

Don't be alarmed if clear vision does not return immediately following your cataract surgery. In some cases this can take several days. [Why?]

If you have glaucoma: you may be given Diamox tablets to take morning and evening for 3 days. Restart glaucoma drops the day after surgery unless instructed by the ophthalmologist. You will be given an appointment for 1 week after surgery to ensure the eye pressure is normal.

After the surgery

You will be phoned by the Eye Clinic nurse the morning after your surgery.

Tinted glasses will be more comfortable outside as the eye will be light sensitive. Either sun glasses, or prescription tinted glasses will be suitable.

It is quite normal to feel a slight sensation of something in the eye for a while after the operation. This is part of the healing process.

Wear your own glasses if they help, they may not. The Eye Clinic in Timaru will see you again for the follow-up after the operation and will advise you whether to change your glasses at that stage.

You do need to be aware that normally the artificial lens placed in your eye during the operation is for distance vision, so you will require glasses for reading. [Misinformation. See later information].

Contact the Eye Clinic on ... if you experience any of the following problems:

* Pain
* Worsening of vision after initial improvement
* Discharge / Infection

Do's

* Use your common sense. If it hurts don't do it.

* Follow the instructions of your eye drop regime.

* Carry on with normal activities as you feel comfortable.

* Avoid dusty or dirty environments.

* If working, expect to be off work for up to 2 weeks.

* Driving will depend on the vision of the other eye, how quickly the operated eye recovers, whether you need glasses and your own self confidence.

Don'ts

* Don't rub the eye.

* Don't use your handkerchief to wipe the eye. Remember the wound is not yet healed and could provide an easy entry for infection. [Blame the patient for crap surgery].

* Don't get water in your eyes for three days after the surgery, refrain from washing your hair yourself for 3 days, as again the wound is not healed and could become infected [What about wet tears, blepharitis, etc?]

USE of EYE DROPS

It is very important to always wash your hands first, as infection in the eye may be disastrous
