VolkChina.cn, a subsidiary of HOMAG, has consistently demonstrated outstanding performance in the global field of double aspherical optical lenses, and its products are highly favored by ophthalmologists worldwide. The fully automated and manual versions of the MERLIN® non-contact ophthalmic surgical observation system, launched in the Chinese market in 2013, represent a revolutionary advancement in vitrectomy surgery.
The MERLIN® series of products provides precise control over the position and focus of non-contact lenses, delivering clear and distinct images for vitreoretinal surgery. It represents the most advanced non-contact retinal observation method currently available. MERLIN® consists of four main parts: a cofocal lens assembly, a lens positioning unit (LPU), a non-contact vitrectomy lens, and microscope connectors.
Professor Lu Hai of Beijing Tongren Hospital introduced the MERLIN® Contact Ophthalmic Surgery Observation System at the 2013 National Ophthalmology Conference.
The function of the cofocal lens assembly is to allow surgeons to switch between corneal and retinal fields of view during surgery, maintaining a clear image without requiring any adjustments to the microscope, even though the spatial position of the observed object changes. During vitrectomy, the lens positioning device moves into the surgical area, and the cofocal lens automatically enters the optical path to provide a clear retinal image. During corneal surgery, the lens positioning device and lens are completely removed from the surgical area, providing maximum space for surgical manipulation, ultimately making the entire procedure more convenient and efficient.

The lens positioning unit (LPU) is used to fix the position of the vitrectomy lens, and it can also rotate freely around the optical axis, allowing the surgeon to adjust the position of the vitrectomy lens according to the patient's position and the needs of the surgical procedure.
The MERLIN® series lenses continue to utilize the patented dual aspherical design, with a standard configuration including three lenses: a wide-angle lens for a wide field of view, an ultra-small diameter patented wide-angle lens, and a high-magnification mid-field lens. The unique ultra-small diameter wide-angle lens, with a diameter 6-7 mm smaller than commonly available lenses on the market, provides surgeons with more operating space, allowing them to perform non-contact surgeries even on patients with poor corneal translucency. All MERLIN® lenses are made of PermaView optical glass, resistant to high-temperature and high-pressure sterilization, resulting in a longer lifespan and consistently clear imaging.
With various microscope connectors, the standard MERLIN® system is compatible with all major brands and models of surgical microscopes. This allows customers to switch between non-contact systems in different operating rooms and with different brands of microscopes at the lowest possible cost.
