Alcon: Dailies Total1
Alcon says its Dailies Total1 for Astigmatism contact lens is the first and only daily disposable toric lens to feature the company’s Water Gradient material. The material features a gradual increase in water content and approaches 100% water at the surface, so all that touches the eye is a cushion of moisture. The lens also integrates Alcon’s SmarTears technology, which involves the release of an ingredient found naturally in tears that helps stabilise the lipid layer of the tear film. The product features Alcon’s Precision Balance 8|4 lens design, which aims to quickly settle to the proper on-eye position, giving the wearer clear vision in a matter of seconds.

Bausch+Lomb: Ultra for Astigmatism
Ultra for Astigmatism is a monthly reusable silicone hydrogel contact lens that Bausch+Lomb says offers stable and consistently clear vision through its OpticAlign design. This is an optimised ballast design that is said to enable rotation at dispensing ≤5˚ for 94% of patients. Additionally, spherical aberration control is optimised in both axes for sharp vision and a reduction in halos and glare while the thin-edge design minimises lid interaction. The company also notes that the axis indicator and orientation mark helps assess rotational stability and to aid application of the lens.

- Oxygen transmission 114 Dk/t (@-3.00D)
Ultravision: Avanti
Ultravision says its Avanti lens has a unique design that guarantees rapid stabilisation and crisp, clear vision at all times by utilising peripheral balancing zones. These zones interact with the top and bottom lids to ensure the lens does not mislocate during wear. According to the company, whether your patient is on the move or laying down to watch TV, lens stability is always maintained when the head is tilted and vision is always consistent through gaze excursions. Avanti features a thin design and silicone hydrogel material that allows for all-day comfort and, with a wide parameter range, offers the convenience of a monthly with the flexibility of a custom made.
- Material: Definitive 74% SiH Blue UV
- Modality: Monthly
- Design: Front-surface toric
- Power range: ±20.00 (0.25DS steps)
- Cylinders: -0.75 to -8.00 (0.25DC steps)
- Axes: 1° to 180° (1° steps)

Menicon: Miru 1day Flat Pack Toric
An advanced daily disposable lens, Miru 1day Flat Pack Toric is said to boast a unique bi-aspheric thinner design that anatomically matches itself to the natural eyelid contours, optimising lens centration and axis stability to support stable, clear vision. Menicon says the lens is intricately designed to provide spherical aberration management that accounts for any slight lens-eye misalignment while maintaining visual performance.
With a smooth 14.2mm diameter surface with minimal thickness, the eyelid is able to glide comfortably over the lens. The company says its user-friendly Smart Fit technology naturally orients the lens correctly no matter which way it is applied. The lens also incorporates innovative Smart Touch technology that combats contamination and boasts slim 1mm-thick packaging.
- Material: Hioxifilcon A
- Modality: Daily wear
- Design: Bi-aspheric
- Power range: +2.00D to -6.00D (-0.25D steps) -6.50D to -10.00D (-0.50D steps)
- Cylinders: -0.75D, -1.25D, -1.75D (-1.75D is only available for axis 180 degrees)
- Axes: 15, 90, 165 and 180 degrees
- Base curve: 8.6mm
- Diameter: 14.2mm

Cantor & Nissel: Hydrocyl
Hydrocyl is said to be a great choice for any patient requiring a soft toric lens. This daily wear, lathe-cut lens, can last patients up to a maximum of 12 months. Its spherical front surface is dynamically stabilised, with the back surface toric design offering maximum stability. The extensive power range and prism-free optical centre is said to ensure optimum vision and its wide range of materials and parameters aim to provide a comfortable fit for most patients. Hydrocyl lenses can also be tinted with pastel tints and opaque tints for cosmetic or therapeutic purposes.

Safilens: Astigma DD
To be effective, Safilens says a toric daily disposable contact lens should properly stabilise and be consistent. Unlike a frequent replacement lens, it has to be thin and comfortable on first fitting. In response, Safilens developed a new simple and effective toric lens design with minimum decentration between surfaces and with inner toricity.
The unique SleekForm stability design is said to use a minimum pure prism profile to achieve quick and precise orientation without the need of enhanced thickness zones in the lens. The lens uses and also benefits from the company’s Fusion technology, in which the synergistic actions of hyaluronic acid and TSP normalise and keep the physiological relation between tear film and ocular surface stable with the aim of giving wearers natural and longer-lasting comfort.

Mark’ennovy: EDOF Toric
Mark’ennovy and the Brien Holden Vision Institute (BHVI), non-profit organisation for innovative vision care solutions, have collaborated on Extended Depth of Focus (EDOF) Toric, a new soft contact lens for presbyopes with astigmatism. This monthly individually crafted lens, powered by the BHVI patented EDOF technology, is said to provide clear vision at all distances.This supports an easy adaptation to the lens, enhancing the overall wearing experience as well as reducing annoying haloes and ghosting. The silicone hydrogel material combines high water content and a low coefficient of friction to improve comfort throughout the day, while its vast range of parameters and low elastic modulus is said to ensure a precise fit and easy handling. EDOF is typically shipped within 72 hours and can be expected in practice within four to five working days.
