Ophthalmic laser systems, including excimer and femtosecond platforms, are widely used in refractive and cataract surgery. Their precision, programmable energy delivery, and integration with imaging or planning modules classify them as active medical devices under Mexican regulation.
This article outlines the main types of ophthalmic laser systems, their classification under COFEPRIS, and practical considerations for grouping and regulatory submissions.
What Are Ophthalmic Laser Systems?
- Excimer Lasers
Excimer lasers are used for corneal reshaping in refractive procedures such as LASIK and PRK. They operate by photoablation, enabling micronlevel corneal tissue removal with minimal thermal impact. Typical system components include the laser module, eyetracking technology, software interface, and disposable patient interface accessories.
- Femtosecond Lasers
Femtosecond lasers emit ultrashort energy pulses for corneal flap creation, cataract fragmentation, lenticule extraction, and precise lamellar dissections. Their use has expanded toward integrated cataract workflows where imaging, docking systems, and surgical planning software operate as a combined platform.
- Hybrid and Integrated Platforms
Some manufacturers provide systems where femtosecond and excimer modules operate in a coordinated workflow. While each module has its own specification, the regulatory submission may address the platform as a unified system when marketed as such.
How Are Ophthalmic Laser Systems Classified in Mexico?
Under the Mexican regulatory framework, ophthalmic laser systems are categorized as active medical devices, as they rely on an external energy source and deliver controlled laser energy to ocular tissue. Because of this, most ophthalmic laser systems (including excimer and femtosecond platforms) are generally classified as Class II medical devices in Mexico.
Accessories designed exclusively for these systems, such as patient interface components or docking elements, may be included under the same registration when they form part of the integrated system.
Different bundles, such as systems sold with diagnostic modules, imaging addons, or upgraded software licenses, may be included under a single registration when the core laser remains unchanged.
Grouping Criteria for Ophthalmic Laser Registrations
Manufacturers may group multiple models or configurations under a single COFEPRIS registration if they meet specific criteria.
- Same Manufacturer
All included laser models must originate from the same legal manufacturer, with consistent quality system documentation.
- Same Commercial Name
Grouping applies when excimer or femtosecond units belong to a recognized product family, share branding, and maintain a similar functional purpose.
- Same Intended Use
Models must be intended for the same surgical applications—e.g., corneal ablation, flap creation, lenticule extraction. Systems with different optical mechanisms or surgical targets usually require their own registration.
- Same Technology Base
Eligibility for grouping depends on shared:
- Operating wavelength and laser type
- Core hardware configuration
- Software architecture
- Patient interface design
Frequently Asked Questions (FAQ)
- What is an ophthalmic laser system?
It is a surgical platform that uses laser energy to reshape eye tissue or assist with corneal and cataract procedures. - Are excimer and femtosecond lasers considered medical devices in Mexico? Yes. Under the COFEPRIS regulatory framework, they are classified as Class II active medical devices.
- Are disposable patient interface components registered separately?
Not when they are designed exclusively for the laser and packaged as part of the system. - Do software updates require new regulatory submissions?
When the software is part of a closed-loop system, it is considered an integral component of the medical device itself. In such cases, updates generally do not require separate regulatory submissions, since the software is already recognized as part of the device.
In contrast, independently registered Software as a Medical Device (SaMD) may require submissions when updates affect its core functionality, but minor interface improvements typically do not.
Conclusion
Ophthalmic laser systems, whether excimer or femtosecond, are regulated in Mexico as Class II medical equipment, requiring detailed technical documentation and clear alignment with COFEPRIS expectations. Understanding their classification and grouping supports efficient submissions and consistent market access.
