What does toric fit mean?

astigmatism
Contact Lens Fitting If you have astigmatism, the curvature of your cornea is not perfectly round and therefore a “toric” lens, which is designed specifically for an eye with astigmatism, would be fit to provide the best vision and lens fit.

What is toric astigmatism?

Toric contact lenses are designed for people with astigmatism. Toric contact lenses correct for astigmatism issues that arise from a different curvature of the cornea or lens in your eye (referred to as regular astigmatism, corneal astigmatism or lenticular astigmatism).

What is the difference between toric and non toric lenses?

Toric contact lenses can rectify astigmatism. The main difference between these and regular lenses is the design. Regular lenses have just one power, but toric lenses have two: one for distance vision and one for astigmatism.

What is spherical and toric?

Standard contact lenses have a spherical surface: think of a slice of the side of a beach ball. A torus, in contrast, is a geometric shape that looks like a donut. A toric lens is shaped like a slice of the side of this donut. The refractive strength increases or decreases gradually as you move around the lens.

Does a toric lens correct astigmatism?

The toric lens may not correct all of the astigmatism, especially if it is severe. Weaker eyeglasses can correct whatever astigmatism remains. In addition, like the conventional lens implant, the toric lens is still a “single focus” lens and therefore reading glasses must still be used if the distance eyesight is good.

Can IOL correct astigmatism?

Corneal astigmatism can be corrected during cataract surgery by implanting a Toric Intraocular lens (IOL), corneal arcuate incisions, or a combination of both.

Who needs toric lenses?

Toric contact lenses are often the best choice for contact lens wearers with an astigmatism, because they’re specifically designed to address the problem. The special shape of a toric lens creates different refractive, or focusing, powers that can help correct either a corneal or a lenticular astigmatism.

What is a monofocal toric lens?

MONOFOCAL TORIC LENS IMPLANTS (Lenses for Astigmatism) The Monofocal Toric Lens Implant is designed to help patients with astigmatism achieve their best possible distance vision following cataract surgery, with minimal need for distance eyeglass correction.

What are spherical lenses?

Spherical lenses—also sometimes referred to as singlets—are optical lenses that feature a spherical surface with a radius of curvature that is consistent across the entire lens. They are constructed such that the light entering them diverges or converges, depending on the lens design.
