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.
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.
