Intraocular Lenses & Common Questions

During a cataract procedure, the natural lens of the eye is that has become cloudy, is removed and replaced with a clear man-made lens. These are called Intraocular Lenses or IOLs.

Excellence in cataract surgery optical outcomes

A recent article from the European Society of Cataract and Refractive Surgery discussed the accuracy cataract surgery outcomes for needing spectacles. It was noted that “we are still hovering at a figure of about 80% of patients achieving within +/- 0.5 units of focus (Dioptres D) of their target. We are very pleased to say that at Cataract Surgery SA 93% of patients achieve within +/- 0.5 D. The article noted the importance of using Swept source OCT biometry Macular OCT Fourth generation IOL prediction formulas Surgeon personalized IOL constants Personalized surgeon induced astigmatism factors Tracking of refractive (spectacle need) outcomes We are also very pleased to say we do all these things at Cataract Surgery SA. This allows us the best chance as indicated in excellent results above of achieving the outcome each individual patient desires for their use of spectacles, or not, after cataract surgery at Cataract Surgery SA.

Contemplating cataract surgery if you live alone?

At Cataract Surgery SA we make cataract surgery for those living alone easier.

Cataract surgery anaesthesia

Cataract surgery anaesthesia is an important issue for patients. There is strong anecdotal evidence that some patients needlessly avoid having cataract surgery, persisting with inferior vision, because of concerns about the anaesthetic.

Cataract surgery and cognitive function

Caregivers of the depressed elderly with significant cataract do hope cataract surgery will improve mood and cognitive function. There is no further evidence to support that this is indeed the case.

Value of cataract surgery

Results of poor vision are an increased risk of falls, depression, suicide, and increased general mortality. The scientific literature provides support for the idea that cataract surgery will improve quality and length of life, whilst decreasing the risk of falls, fracture, and motor vehicle accidents.

Cataracts and Balance

Measurement of balance in adults 45 to 85 years old showed cataract and reduced visual acuity were associated with poorer balance. Age related macular degeneration and glaucoma in contrast were not associated with reduced balance. Balance was tested by whether the patient could stand on one leg for at least 60 seconds. For each line of worse visual acuity there was 15% higher odds of failing the balance test. This research supports previous research elsewhere showing that there is an increased risk of falls associated with cataracts, and that this risk decreases following cataract surgery in one eye, and again following cataract surgery in the fellow eye if it has cataracts also.
