LENZ Therapeutics soars 20.7% after FDA-approved VIZZ launch for presbyopia patients

LENZ Therapeutics has announced that VIZZ, the first and only FDA-approved aceclidine-based eye drop for presbyopia in adults, is now available in the United States, with nationwide sample distribution to eye care professionals underway and commercial shipments to consumers starting in October.

This launch positions LENZ as a key player in the large and previously underserved U.S. presbyopia market, with clinical trial results showing rapid and sustained improvement in near vision for the majority of patients.

We’ll look at how the entry of VIZZ as a first-of-its-kind treatment shapes LENZ Therapeutics’ investment narrative and future growth prospects.

For shareholders in LENZ Therapeutics, the big picture centers on belief in the commercial and clinical potential of VIZZ, the just-launched, FDA-approved eye drop for presbyopia, a market affecting millions of adults. The company’s move from pre-commercial to commercial-stage with VIZZ marks a shift in the short-term catalysts, immediately bringing execution risk and real-world uptake into focus. Previously, the key drivers were regulatory progress and an expanding pipeline, but now early sales metrics, physician feedback and distribution success will likely drive sentiment and price movement.

This approval pushes LENZ closer to meaningful revenue generation, but with losses widening and limited current revenues, financial performance in the near term remains a challenge. While recent share price gains suggest high expectations, failure to achieve broad physician adoption or unexpected safety concerns could reverse this optimism. The VIZZ launch is material, shifting the narrative from promise to proof, and the stakes have risen accordingly.

On the flip side, as execution risk grows, so does exposure if uptake falls short of investor hopes.

LENZ Therapeutics’ shares have been on the rise but are still potentially undervalued.
