Bausch + Lomb Ultra Multifocal for Astigmatism
Finally, a standard issue multifocal toric contact lens. This lens uses Bausch + Lomb’s 3-Zone Progressive Design to provide presbyopic correction and the company’s OpticAlign design for toric stabilization. These are the same design elements already familiar in Bausch + Lomb Ultra for Presbyopia and Bausch + Lomb Ultra for Astigmatism.2
The lens is made of samfilcon A with MoistureSeal technology, and it has a Dk/t of 163 and water content of 46 percent. Although it is a monthly disposable, it is not yet approved for seven-day extended wear as other Ultra family lenses.
Bausch + Lomb Ultra Multifocal for Astigmatism is available in a base curve of 8.6 mm and a diameter of 14.5 mm. The powers range from +4.00 D to -6.00 D in 0.25 steps and extend to -9.00 D in 0.50 steps.
Cylinder choices include -0.75 D, -1.25 D, and -1.75 D and axes 10 degrees to 180 degrees in 10-degree steps. The low add covers spectacle add powers +0.75 D to +1.50 D, and the high add is prescribed for spectacle adds of +1.75 D to +2.50 D.2
It’s easy to say “Wow, we need this in a daily disposable.” But it is impressive to see the lens debuted with such expansive parameters and, as always, ODs must embrace the technology present before a company takes the next step toward further specializing a lens. In addition, keeping it as a monthly modality helps control the cost for the patient.

CooperVision’s myopia control soft lens is not yet available in the U.S., but it is already on the shelves in Canada and the UK and multiple countries in Asia and Europe.3 ODs know of the need for retarding myopic progression in youth. Aside from self-image concerns and inconvenience of a large myopic refraction, myopia presents serious pathological consequences such as retinal detachment and glaucoma.4
It is encouraging to see this technology come to market because it will raise awareness among the public and obligation among doctors to take action.
Historical treatments have included atropine, orthokeratology (ortho-K), progressive addition lenses (PALs), or bifocal spectacles. Over the past decade, ODs have also learned that time spent outdoors has an impact on the onset of myopa. Though there is not yet a consensus on the minimum amount of time needed, more time outside is better.4
The lens is designed as a bull’s eye pattern with a distance center and 2.00 D of defocus in the peripheral treatment zone. Some wearers may experience shadowing during adaptation, but it often dissipates in approximately one week.
MiSight is made of omafilcon A—the same material as CooperVision’s Proclear. The high wettability and water content of 60 percent—as well as the daily disposable wear modality—make it an ideal option for fitting pediatric patients.3
This reduces the influence of questionable hygiene habits and over wear. The parameters currently available in approved countries are -0.25 to -6.00 D in 0.25 D steps with an 8.7 mm base curve, 14.2 mm diameter, and 28 Dk/t, and it is sold in a 30-pack.
Each of these contact lens advances warrants a specialty fit. They require ODs to get out of their box and present technology that may take more time to fit, require additional coaching, or be more costly to the patient.
But they are also technologies that can change a patient’s quality of life, both now and for years to come. It is an opportunity for ODs to embrace technology, become early adapters, and differentiate their services to the patient. Set yourself apart by offering your patients the latest technology available.
