LENZ Therapeutics, Inc. (Nasdaq: LENZ) announced April 20, 2026, that it has submitted a Marketing Authorization Application (MAA) to the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) for VIZZ® (aceclidine ophthalmic solution) 1.44%, seeking approval for presbyopia treatment in adults.

The San Diego-based pharmaceutical company’s UK regulatory submission represents a significant milestone in expanding access to what the company describes as the first and only aceclidine-based eye drop specifically developed for presbyopia treatment.

Regulatory Progress Across Europe

The MHRA submission builds on LENZ Therapeutics’ recent regulatory success in Europe, where the European Medicines Agency (EMA) validated the company’s MAA for VIZZ in March 2026. This dual-track regulatory approach positions the company to potentially serve both EU and UK markets simultaneously.

Presbyopia, an age-related vision condition affecting near-sight clarity, impacts millions of adults worldwide. The condition typically begins affecting individuals in their 40s and progressively worsens with age, creating a substantial market opportunity for effective treatments.

Market Implications and Timeline

VIZZ’s unique aceclidine-based formulation differentiates it from existing presbyopia treatments in the market. The 1.44% concentration represents a specific therapeutic approach that LENZ has developed through clinical trials and regulatory review processes.

The company’s strategic focus on both EU and UK markets reflects the significant commercial potential for presbyopia treatments in these regions. With aging populations across Europe and the UK, demand for effective presbyopia solutions continues growing.

Next Steps in Approval Process

The MHRA will now conduct its comprehensive review of LENZ Therapeutics’ submission, evaluating VIZZ’s safety and efficacy data. This review process typically involves multiple phases of regulatory assessment before final approval decisions.

Success in both EU and UK markets would provide LENZ Therapeutics with substantial commercial opportunities and establish VIZZ as a leading presbyopia treatment option for European patients seeking alternatives to reading glasses or surgical interventions.
