Cataract Surgery In Perth
Aculase Cataract Surgery
Dr Chan has performed thousands of cataract surgeries in Perth and has had impressive results. Now with a state of the art laser cataract system, we are one of a handful of clinics to offer optional laser cataract surgery in Perth. Laser cataract surgery can offer even higher surgical precision especially when a multifocal lens implant is used. Patients who already have had their cataract surgeries done could also have other laser treatments to enhance their results.
We don't charge gap surgical fees for cataract surgery if you are with major health funds. In another word, most patient's cataract surgical fees are fully funded with us for most hospital cover policies. Perth Eye Hospital also has a reduced hospital fee program for pensioners if you do not hold an active hospital cover policy.
What is a Lens Cataract
As the natural internal lens ages, it becomes progressively less transparent and its refractive power may change. It is termed a cataract (obstruction) when the aged natural lens causes deterioration in vision due to scattering of light and reduction in the amount of light entering the eye. Cataract affected vision may be like looking through frosted glass or there may be glare in bright lights or with night driving. On the other hand, vision deterioration from cataract can be very slow. A lot of patients can have severely degraded vision for decades without knowing it due to the slow deterioration. Eventually cataracts can cause blindness. Cataracts can only be treated with surgery.
Cataract Surgery
Cataract Extraction and Intraocular Lens Implantation procedures have been performed since the 1940’s. It is one of the most commonly performed elective operations around the world. During the last 10 years cataract procedures have vastly improved in terms of recovery time, safety and refractive predictability.
The aim of the cataract surgery is to remove the blurry cataractous lens within the eye and replace it with a clear lens implant. Cataract surgery is effectively a lens exchange procedure.
Intraocular Lens Implant (IOL)
This replacement lens implant (IOL) can be of various custom power according to the patient's need. Therefore the patient’s refractive errors can also be corrected at the time of the surgery by using the appropriate IOL. Modern lens implants can correct myopia, hyperopia, astigmatism, some higher order aberrations and presbyopia.
Various types of advanced intraocular lens implants can provide accurate multifocal vision or increased depth of focus which result in spectacle free distance, intermediate and reading vision. With current technology, this form of multifocal vision is the closest match to the vision in a younger eye before the onset of presbyopia.
Most health funds fully cover these advanced lens implants.
However, some cataract patients are not suitable for these lens implants due to various individual parameters such as refractive error, concurrent eye problems and lifestyle.
LASER Cataract Surgery System
Laser cataract surgery system is also available for improved surgical accuracy. Laser cataract system is a premium option available to improve precision of several critical steps in cataract surgery to ensure the best outcome and comfort. The laser procedure is performed just prior to cataract surgery within the same hospital visit.
Perth Eye Hospital - Perth's Premiere Eye Surgery Facility
You will have your cataract surgery at Perth eye hospital. Perth Eye Hospital is Perth's only certified eye hospital. You can be confident with your cataract surgery at Perth Eye Hospital since this ultra-modern facility is one of the largest cataract surgery centres in Perth for over 20 years.
Cataract surgery is a very short comfortable local anaesthetic procedure performed in an operating theatre. Patients are only expected to be in the hospital for several hours.
Accurate Surgery begins with precise measurements in the clinic
IOL Biometry is a set of eye measurement test and calculation that predicts the power of the lens implant required for each cataract surgery patient. We have the latest bio-scanners in our clinic to ensure the most accurate results.
Modern biometry is performed with laser interferometry. Laser measurements are vastly superior to ultrasound measurements which was the standard not so long ago. Zeiss IOL Master is an automated non-contact laser biometer which measures the length of the eye, curvature of the cornea and other parameters.
We also use a Wavelight Oculyser to improve the accuracy of corneal curvature measurements. This is especially important on eyes with Astigmatism and when a Tri-focal Intra Ocular Lens (IOL) is used. This instrument is not commonly found in most eye clinics as it's mainly used to precisely measure the shape of cornea for Laser corneal eye surgery profile targeting.
In some cases we also use an OCT (optical coherent tomography) laser scanner to detect any abnormalities in the retina prior to surgery. An OCT is similar to a CT scan for the eye but only laser light is used (no xray). Cross sectional scans of the eye and retinal fundus photographs are taken at the same time to allow diagnosis of subtle retinal problems. Undetected abnormal shape in the retina can drastically reduce surgical accuracy and safety.
Using all these data, our software performs the necessary calculations to custom derive the required lens power for each patient. Ray-tracing software calculation is used in cases with astigmatism and patients who previously have had laser eye surgery.
All these tests are quick and painless. They are performed routinely before your consultation at our state of the art clinic. To find out more about cataract surgery in Perth Eye Hospital or to book a consultation at our Nedlands clinic, call us today on (08) 9388 1828.
