Cataract /Lens Refractive technology has evolved significantly over the past 20 years to make it one of the safest outpatient procedures performed in North America. We use the most advanced and trusted technology and techniques at both the diagnostic and surgical stages to ensure that you get the safest and best possible visual improvement.
It is extremely important that the most accurate and detailed representation of your corneal and visual system architecture is obtained to allow for superior vision correction.
This representation is achieved through:
1. Obtaining accurate measurements and
2. Applying the ISA® Customized Algorithm for the systematic validation and weighting of each of these measurements to determine the unique ISA® Customized 13-D Diagnostic Set that best captures any given individual’s corneal and visual system architecture.
The diagnostic set is important because each diagnostic tool is uniquely able to measure along specific parameters. Utilizing a combination of tools, sometimes consecutively at different temporal points, is necessary to obtain the most accurate representation. The full suite of diagnostic tools will be discussed by our Surgeon and team of Vision Care Associates at your ISA® Customized Surgical Consultation.
There are numerous surgical technologies (ie. Femtosecond Lasers for Blade-Free Surgery); each produces optimal results under a specific set of surgical parameters. Applying the right surgical technology as optimized for your treatment and your eyes is necessary to produce superior post-operative results.
This is achieved through:
1. Using the ISA® Customized Surgical Technique to determine which specific cataract technology to use and
2. Applying the ISA® Customized Algorithm to determine which lens is uniquely suited to correcting your vision.
Our Surgeon and team of Vision Care Associates will discuss the best options for you and make a customized surgical and refractive recommendation at your ISA® Customized Surgical Consultation.
Different lenses can optimally correct for different visual requirements; having the appropriate procedure, lens, or pairing of lenses is extremely important to achieving the best visual outcome from your cataract surgery. Using the ISA® Customized Algorithm, our Surgeon will determine the right lens for each of your eyes.
Optimized Monofocal Lenses
These intraocular lenses are typically optimized for asphericity, filtering of harmful light, chromatic aberration and accurate effective lens positioning when possible.
Adjustable lenses are monofocal lenses that allow for the refinement of your eyeglass prescription post-operatively.
Diffractive lenses utilize optical principles to divide light into two or more focal points so that you can see at those discrete focal points. This decreases but does not completely eliminate the need for reading glasses. Some diffractive lenses utilize the principle of diffraction to minimize chromatic aberration to increase contrast and clarity while maximizing range of vision.
Toric lenses can correct for astigmatism to ensure that your post-operative vision is fully optimized.
Accommodative lenses have the potential to enable vision at a discreet range of focal points. This decreases but does not completely eliminate the need for reading glasses. The mechanism of action of some of these lenses is currently under debate.
These combine the benefits of various lens types.
ISA® Customized Bespoke Blended Vision
Blended Vision is the use of one eye for distance vision and the other eye for intermediate vision. It can involve using a combination of different technologies, optical properties and surgical techniques including diffractive lenses, laser vision correction techniques and bioptics to optimize the result depending on the patient’s refractive error, visual architecture and vision requirements.
Arcuate Keratotomy (with or without Femtosecond Laser)
This is a corneal procedure used in combination with any of the above lenses to correct for astigmatism at the time of cataract surgery. It involves the creation of typically paired corneal channels that act to flatten the cornea and therefore decrease astigmatism in the location of those channels. These channels can be created with a Femtosecond Laser for increased accuracy, consistency, corneal structural integrity and a decreased chance of infection.
Our Surgeon will discuss the lens selections that are best suited for your visual needs based on the ISA® Customized Algorithm and make a surgical and refractive recommendation.
