Cataract Testing

As the providers of your cataract surgery, the main goal of Canadian ophthalmologists is to provide you with the best visual outcome possible.

To help achieve this goal, some pre-surgery testing options that are not typically covered by your provincial or territorial plan are available for you to consider.

One option is special testing with the IOLMaster, and the second is Wavefront Analysis to facilitate selecting the ideal intraocular lens for you.

IOLMaster Testing

The IOLMaster uses laser technology to measure the length of the eye. Measuring the length of the eye accurately is extremely important in cataract surgery, as it allows the eye surgeon to select the right power lens to implant for each patient.

The IOLMaster is the latest technology in this area, and is more accurate than any other method, including the ultrasound test typically covered by provincial and territorial health plans.

IOLMaster testing is an option available for patients who would like the best possible accuracy available for lens selection. In many cases the increase in accuracy reduces the need for glasses after surgery. IOLMaster testing is considered non-essential and is not usually covered by provincial and territorial health plans; the cost for testing varies but the Canadian Ophthalmological Society recommends that charges for this test be approximately $193.

Wavefront Analysis

Wavefront analysis uses a special device to precisely measure the unique irregularities and variations in the cornea. This analysis has been likened to taking a ‘fingerprint’ of the eye.

With your chin resting on the device, you will be asked to stare past what is called a target light. A sensor will measure the irregularities in the wavefront pattern of the light reflecting from your cornea.

Wavefront measuring devices create a precise map of the cornea. It is very detailed and records subtle distortions in your cornea. Using the information from this map, your eye surgeon can select the intraocular lens used in your surgery to correct for some of these measured distortions, giving you clearer vision than would be possible with conventional lenses.

Wavefront analysis is considered non-essential and is not usually covered by provincial and territorial health plans; the cost for testing varies but the Canadian Ophthalmological Society recommends that charges for this test be approximately $127.
