fasting before cataract eye surgery

Why is fasting before cataract eye surgery important ?

Sometimes, even though patients know they will have intravenous sedation, they still do not understand why fasting before cataract eye surgery is necessary. On occasion a patient arrives for cataract surgery having eaten breakfast and unfortunately in these cases surgery has to be postponed, which can be very inconvenient for patients and doctors alike.

So why do you need to fast?

Fasting before cataract eye surgery reduces the risk of stomach contents/acid going the wrong way down into your lungs while you are asleep. Stomach acid can cause lung damage.

What is the correct way for fasting before cataract surgery?

  • NO solid food is to be eaten for at least 6 hours prior to your admission time.
  • NO fluids (except water, black tea or black coffee) are to be taken for at least 2 hours before your admission time.

Your regular medications may be taken at their usual time with a sip of water.

Cataracts – Causes, Symptoms, Diagnosis and Treatments

What are cataracts ?

Cataracts are a clouding of the crystalline lens of the eye. This in turn affects vision. Cataracts form for many reasons but the most common is age.  It is normal for people over the age of 65 to have some mild form of cataracts. Causes of Cataract development include age, steroid use, trauma, radiation, or as a result of other eye conditions such as glaucoma.  Cataracts can occur in one or both eyes, sometimes years apart, but it cannot spread from one eye to another.

State of the art – Medical best practice and architecture meet

IT’S HARD TO believe that beneath the welcoming, streamlined elegance and efficiency of the award-winning FOCUS Eye Centre in Kingsford, Sydney, is a century-old cottage. More remarkable is that the renovation work was completed to a strict six-month timetable on the very day promised by its architect Georgina Wilson.

How to choose an Ophthalmologist that’s right for you

When it comes to eye surgery, there are a couple of key decisions that need to be made.

The first is to commit to the treatment and the next is to choose a particular Ophthalmologist to proceed. For some people finding the right specialist often comes before deciding to go ahead with treatment.

Making a choice is very much a personal process, but there’s a number of things to know — and questions to ask – that can help you make an informed decision with which you can be confident and comfortable and that’s right for you.

Astigmatism correction with Acrysof T2 Toric IOL

“Astigmatism Correction with Acrysof T2 Toric IOL”

at 18th European Society of Cataract & Refractive Surgeons (ESCRS) Winter Meeting in Ljubljana, Slovenia

by Dr Richard Smith (presenter), Dr Margaret Kearns (co-author)


This study indicated that accurate correction of astigmatism is possible down to +/- 0.5 Dioptre. This is an important element in achieving better vision from cataract surgery.

Cataract Surgery after Laser Refractive Surgery

“Cataract Surgery after Laser Refractive Surgery”

at Australasian Society of Cataract and Refractive Surgery Annual Meeting July 2013

by Dr Margaret Kearns (presenter), Dr Richard Smith (co-author)


This study examined refractive outcomes of cataract surgery in subjects who had previously had laser vision correction. In these cases it is more difficult to predict correct IOL power pre-op.

The Haigis-L formula yielded fair results.



New Agents for Treating Dry Eye Syndrome

Authors: Simon E. Skalicky, Con Petsoglou, Avinash Gurbaxani, Clare L. Fraser, Peter McCluskey

Published article – abstract

Dry eye syndrome (DES) is characterized by an inadequate volume and/or quality of tears resulting in chronic ocular surface irritation and inflammation. Affecting up to 30 % of adults, DES has a considerable impact on visual function and quality of life. DES may complicate allergic ocular disease and allergy medication may exacerbate DES. The pathophysiology of DES involves osmotic, mechanical and inflammatory insults to the tear film, epithelium and subepithelial nerve plexus. Various immune-related molecular targets have been the focus of research aimed at developing new therapeutic agents for treating DES. This article provides an overview of established, new and future agents for treating DES.
