Buried within the seemingly mundane details of Carl Zeiss Meditec's Q2 2024 earnings call lies a story of seismic shifts, a silent revolution brewing in the world of vision correction. It's a story of laser-precise battles for market share, price-sensitive consumers, and a new generation of technology poised to reshape the industry. And it's a story that, if you're not paying close attention, you might miss entirely.

While analysts have understandably focused on the company's overall performance, the impact of destocking in China, and the integration of the D.O.R.C. acquisition, a subtle yet crucial trend has flown under the radar: the rising popularity of LASIK procedures in China, potentially at the expense of Zeiss's flagship SMILE procedure. This shift, though currently driven by economic factors, could have lasting consequences for the company's future growth and profitability.

Remember, Zeiss has bet big on SMILE. Their VisuMax laser, a critical component of the SMILE procedure, has become a global success story with over 2,100 units installed worldwide. They've even launched the next-generation VISUMAX 800, which promises even greater precision and efficiency. The company has built its refractive consumables business around this technology, enjoying higher margins and a captive market.

But China, a critical growth market for Zeiss, is throwing a wrench in the works. While procedure volumes are still growing year-on-year, a key detail from the earnings call reveals a shift in consumer preferences. Justus Wehmer, Zeiss's CFO, mentioned a "slightly higher share of LASIK procedures on our installed base, signaling that consumers favor less expensive options."

This seemingly innocuous statement carries significant weight. It suggests that, despite SMILE's purported advantages, price sensitivity is becoming a deciding factor for Chinese consumers. And this trend could be exacerbated by the economic climate, with Wehmer noting "pressure on the end patient price of SMILE among hospital operators."

Shifting Procedure Preferences in China

Here's where the hypothesis gets interesting. Let's assume Zeiss's estimate of 90% SMILE procedures on their installed base in normal circumstances is accurate. Wehmer states that they're seeing LASIK "increase temporarily to levels that are closer to 20%." This implies a 10 percentage point shift from SMILE to LASIK.

Now, consider the financial impact. If SMILE consumables command a higher margin than LASIK, as is likely, this shift directly impacts Zeiss's profitability. Even if procedure volumes remain robust, the company could find itself generating lower margins per procedure, impacting their overall earnings.

And the potential long-term implications are even more concerning. If this trend persists, it could undermine Zeiss's strategy of building its refractive business around SMILE. The company is pinning its hopes on the VISUMAX 800 to boost SMILE adoption. But what if Chinese consumers, accustomed to the lower price point of LASIK, are reluctant to pay a premium for the newer technology?

Zeiss faces a delicate balancing act. They need to maintain SMILE's premium positioning while also addressing the growing demand for more affordable options. The rollout of the VISUMAX 800 in China in 2025 could be a critical turning point. The company will need to demonstrate the value proposition of the new technology, potentially through innovative financing models or targeted marketing campaigns.

The stakes are high. Zeiss's success in China hinges on their ability to navigate these shifting consumer preferences and maintain their leadership in the refractive market. The silent revolution in laser vision correction has begun, and Zeiss needs to act decisively to ensure they remain at the forefront of this rapidly evolving industry.

"Fun Fact: The first excimer laser, the type used in both LASIK and SMILE procedures, was initially used to etch computer chips in the 1970s. It wasn't until the 1980s that its potential for vision correction was realized, leading to a revolution in how we address refractive errors."
