What is a Toric Lens?
Astigmatism occurs when the cornea is shaped more like a football than a round basketball, causing light to focus unevenly on the retina and producing blurred or distorted vision at all distances. A toric IOL is precisely engineered to counteract that irregular curvature, neutralizing astigmatism at the same time the cataract is corrected. The result is a clearer, more focused vision — often reducing or eliminating the need for glasses to correct astigmatism after surgery.
What is a Multifocal Lens?
A standard IOL typically provides excellent vision at a single distance — either distance or near vision— meaning you will still rely on reading glasses for up-close tasks or distance glasses for far work. Multifocal IOLs are designed to give you a range of vision, allowing you to see clearly at multiple distances without glasses.
These lenses can dramatically improve near and intermediate vision, making everyday activities like reading, using a phone, and working at a computer easier without reaching for readers. The tradeoff is that some patients notice halos or glare around lights at night, particularly in the first few months after surgery as the brain adapts. For most people, these effects diminish over time.
Multifocal lenses aren't the right choice for every patient. During your evaluation, we'll review your lifestyle, visual priorities, and eye health to determine whether a multifocal or standard monofocal lens will serve you best.
What is an Extended depth-of-focus (EDOF) Lens?
EDOF lens offers a continuous, elongated focal range rather than distinct focal points, allowing you to see well at distance and at intermediate. You will still need glasses for up-close tasks, but can comfortably work on a computer, drive, and do daily activities without glasses.
EDOF lens aren't the right choice for every patient. During your evaluation, we'll review your lifestyle, visual priorities, and eye health to determine whether an EDOF or standard monofocal lens will serve you best.
What Is Monovision?
Monovision is a vision correction in which one eye is intentionally corrected for distance and the other for near or intermediate vision. The brain learns to use whichever eye produces the sharper image for the task at hand, reducing dependence on glasses for both distance and near work. Monovision works well for many patients, but it isn't ideal for everyone — which is why we'll thoroughly evaluate each eye and discuss your goals before recommending a lens strategy.
