J&J, Alcon Expand Toric CL Parameters

All the above lenses from both manufacturers now have cylinder options from -0.75D to -2.75D in half-diopter steps, although not all of the highest cyl powers are available at every axis position.

The new Total30 parameter is available now and the others will be released in the second half of the year. At a press event, the company emphasized the importance of having more parameter options on hand for new contact lens patients in particular to ensure they have an easy on-ramp to lens wear.Earlier this week, Johnson & Johnson Vision said that its Acuvue Oasys 1-Day toric lens now comes with a -2.75D cyl option, in addition to existing powers of -0.75D, -1.25D, -1.75D and -2.25D. The move follows a similar expansion the company made to its monthly replacement lens Acuvue Vita earlier this year.
