Comment on: Toric intraocular lenses: Expanding indications and preoperative and surgical considerations to improve outcomes.

Dear Editor,

We read with interest the review article on toric intraocular lenses (IOLs), “Expanding indications and preoperative and surgical considerations to improve outcomes,” by Singh et al.[1] Various brands of toric IOLs were included in the two tables in the article, but the Envista Toric IOL (MX60T) was absent from the monofocal list and was found mistakenly in the multifocal IOL chart.

I have been using this Envista Toric IOL, which is a monofocal, aspheric IOL since long and it gives exacting astigmatic correction with dependable rotational stability and pristine visual clarity. The advantages are aberration-free and glistening-free performance in the hydrophobic acrylic platform.[2] This lens can be delivered through a 2.2-mm incision with minimal surgical-induced astigmatism using the Bausch and Lomb injector.

The distinctive design has more radial compression force, and the step vaulted haptics provide greater capsular bag contact of the 360° square edge optic, preventing posterior capsular bag opacification. I find the unique haptic fenestrations extremely helpful to facilitate intraoperative lens manipulation in the correct axis very easily. It is available in powers +6 D to +30 D range and a cylinder power 1.25 D to 5.75 D in the IOL plane. The online calculation at Envista Toric calculator site gives precise and pretty printouts for intraoperative use and the IOL had <5° rotation at 6 months.
