Demand for minimally invasive treatment is growing. HOYA develops medical endoscopes that enable early diagnosis and treatment under the PENTAX brand. HOYA also offers medical devices such as intraocular lenses and orthopedic implants.

Medical Endoscopes

Medical flexible endoscopes are used in minimally invasive medical procedures worldwide as a method that is beneficial for both physicians and patients.
With a wide array of products, including video scopes and fiberscopes, and high-quality after-sales services, PENTAX Medical contributes to diagnosis, treatment, and medical research in diverse departments, including those related to the digestive organs, otorhinolaryngology, and respiratory disease.

Through the strategic acquisition of majority shares of Wassenburg, HOYA now offers high-end automated endoscope reprocessors (AERs). As the number of endoscopy procedures increases and the importance of endoscope reprocessing grows driven by the rising hygienic awareness around washing and disinfection of flexible endoscopes, demand for a cutting-edge and advanced product solution is increasing.
(AERs and related products made by Wassenburg Medical are unapproved by MHLW in Japan)

Laparoscopic Surgical Instruments

Microline laparoscopic surgical instruments integrate disposable and reusable functions that enhance performance, reduce cost and improve patient outcome. The MiFusion product line offers a broad spectrum of open and laparoscopic instruments used to seal and divide tissue utilizing proprietary Thermal Fusion technology.

Intraocular Lenses

An intraocular lens (IOL) is an artificial crystalline lens used in an eye after a clouding crystalline lens has been removed during cataract surgery. It is an innovative medical device that enables people who once suffered from cataracts to see normally again. HOYA Surgical Optics manufactures and sells lens injection systems that facilitate surgery, along with soft, foldable IOLs that can be inserted through extremely small incisions (1.8mm incisions).

Prosthetic Ceramic Fillers and Metallic Implants

Apatite products are used mainly in the fields of orthopedics, brain surgery and dentistry as prosthetic fillers for bone defects. APACERAM, one of HOYA Technosurgical's apatite products, is made of hydroxyapatite, a chemical compound virtually the same as the constituents of human bone. Hydroxyapatite implantation is safe, and over time, the implant is partially resorbed and replaced by natural bone, as it becomes part of the body.

Metallic orthopedic implants are used to plate a broken bone. HOYA Technosurgical manufactures and sells products using titanium of superior strength and biocompatibility. HOYA Technosurgical encourages early rehabilitation of patients.
