The Enova Maestro is indicated for the primary implantation of a posterior chamber trifocal intraocular lens in adult patients with cataract or clear lens extraction seeking spectacle independence across the full visual range.
Adult patients undergoing cataract surgery or clear lens extraction who seek spectacle independence across the full visual range.
Macular degeneration, significant corneal pathology, uncontrolled glaucoma, or pupil abnormalities.
Photopic and mesopic conditions, pupil size and patient expectations are judged case by case by the prescribing physician.
Every lens in the Enova family is built on the same proprietary hydrophobic acrylic. Glistening, the fluid microvacuoles that form inside the optic over the years and scatter incoming light, is the failure mode this material was designed to eliminate. In an in vitro study at the Intermountain Ocular Research Center, University of Utah, the material showed no glistening formation.
Conventional trifocal IOLs rely on concentric diffractive ring steps. Each step scatters light at the transition. STT replaces the ring steps with a continuous sinusoidal wave, distributing light energy smoothly across the full defocus range. The result for the Maestro: clinically verified performance at distance (0 D), intermediate (−1.5 D), and near (−3.0 D), with a dysphotopsia profile distinct from any other trifocal on the market.

An independent University of Utah study found that the Enova hydrophobic acrylic exhibited no glistening formation after hydration and temperature variation, where AcrySof and Tecnis lenses showed mild to trace glistenings.
The preloaded Rotaryjet system removes preparation steps in theatre. The lens advances with one smooth rotation, and that reproducibility matters to me case after case.
The Enova Maestro is supplied preloaded in the Rotaryjet single-use injector. The rotary mechanism advances the lens through a 2.2mm incision with a single smooth rotation, no cartridge preparation, no lens handling, consistent delivery every time.
Inspect the preloaded injector. Confirm lens orientation and injector integrity before use.
Place the injector tip through the 2.2mm incision. Rotate smoothly, continuous motion, constant pressure.
Confirm haptic deployment in the capsular bag. Centre the optic. Standard aspiration to complete.
The Enova Maestro Toric, Advanced EDOF, and Monofocal GF3 share the same material and delivery platform. Select by indication.
Glistening-free hydrophobic acrylic monofocal for primary cataract surgery, non-preloaded or preloaded.
