Patient Candidacy
Who Is the enVista Envy Best For?
enVista Envy is suited for patients who want trifocal visual freedom with a particularly favorable side effect profile.
- Patients seeking independence from near, intermediate, and distance glasses
- Patients who want a trifocal lens but are concerned about halos and glare
- Patients without significant corneal irregularities or macular disease
As with all trifocal IOLs, some adaptation period is expected. Patients with extreme nighttime driving demands may wish to consider an EDOF lens such as Clareon Vivity or TECNIS PureSee.
