Choosing a lens to suit your lifestyle:
The Halifax Vision Surgical Centre understands the importance of choosing the right lens for your eyes. We work together with you to understand your lifestyle in order to make an informed decision. When it comes to having refractive eye surgery we offer a variety of procedures and there is something for everyone. Our surgeons are dedicated to providing you with the best quality diagnostic testing and surgical procedures to serve your eye care needs.
During your consultation, you and the surgeon will discuss your options and come up with a solution based on your needs and your desired outcome.
- Do you do a lot of reading?
- Do you drive for long periods of time?
- Do you use the computer for extended lengths?
- Do you suffer from dry eye?
Intraocular Lens (IOL) options available depending on your needs:
The most common type of lens used with cataract surgery is called a monofocal IOL. It has one focusing distance. It allows people to see far away and glasses will be required for reading and close-up work.
Astigmatism correcting lenses:
For people with astigmatism, there is an IOL called a toric lens. Astigmatism is a refractive error caused by an uneven curve in your cornea or lens. People with astigmatism have an eye that is shaped more like a football than a baseball. The toric lens is designed to correct that refractive error. Similar to a monofocal lens, it will correct distance vision only meaning glasses will be needed for up close tasks and reading.
Extended Depth of Focus / Trifocal lenses :
Extended Depth of Focus or Trifocal IOL’s provide both distance vision and some intermediate/near focus at the same time. The lenses have different focal zones and allow patients to be less dependent on glasses for intermediate or near tasks. They are designed so that your brain learns to select the right focus automatically.
This provides comprehensive information for pre-operative assessment and post-operative investigations. Some of the information that is provided includes:
- Corneal Topography
- Spherical Aberration Measurement
- Astigmatism lens Planning Tool
With a recent upgrade in our biometry equipment, The ZEISS IOLMaster® 700 now allows us to measure both eyes in less than 45 seconds.
With the ZEISS IOLMaster 700 you get a piece of cutting-edge technology that points the way to the future of optical biometry.
The ZEISS CALLISTO eye matches the reference image for alignment to the patient’s eye and continuously tracks the image to provide assistance overlays. The target axis is displayed as an overlay on the live image for markerless and precise toric IOL alignment. It is no longer necessary to physically mark the cornea before surgery.
