Milestones in Benz R&D History

1987   Developed a unique and comprehensive purification process for 2-HEMA monomer that has been the source of raw material for most of the soft lenses produced worldwide since 1987.

1989   Developed the first precision, isotropically expanding polymacon and hefilcon contact lens polymers. These were the first commercially available materials that allowed soft contact lenses to be manufactured to order rather than manufactured for inventory. This development greatly reduced the cost of producing custom lenses.

1991   Developed a high volume process to produce precision ground contact lens blanks, where all surfaces are ground, eliminating the need to trim blanks before manufacturing a contact lens. Benz blanks remain the benchmark of the industry in their precision of diameter, squareness, parallel and thickness. This high volume manufacturing process is operated using Statistical Process Control.

1993   Developed and patented worldwide, an Optical Blocking and Inspection machine that delivers micron accurate radius measurement and concentric blocking. Patented 1994.

1994   Developed the first and still the only dimensionally stable soft contact lens material that remains 100% saturated on the eye. This family of performance materials is called Benz-G materials. Today, almost 10 years later, there is no other material available to the specialty lens manufacturer that matches the on-eye performance of Benz-G materials. Patented 1995.  Achieved ISO 9001 certification for monomer, and polymer blank manufacturing and development.

1995-96   Developed the first fully integrated automatic lens manufacturing process utilizing micron precision Optical Blocking. Developed automatic machinery to provide customers, at no additional cost, with blanks containing a precision precut that reduces manufacturing time and expensive diamond tool wear.

1997   Developed Benz IOL25 UV, a unique and mechanically superior hydrophilic IOL material. This material allows IOL manufacturers to precisely hit target even at 35+ Diopters and create designs that can be inserted through 1.2 mm incisions. Patented 2002.

1998-99   Achieved EN 46002 for the manufacture of custom base curves, lenses and dry polished intraocular lenses using Integrated Lens Manufacturing with Optical Blocking. Developed the first commercially available disposable lens that remains 100% saturated and dimensionally stable on the eye. This lens material is based on BENZ-G 5X and is called Extreme H2O. This product is manufactured and sold by Hydrogel Vision Corporation.

2001   Commercialized an automated lens manufacturing system utilizing micron accurate Optical Blocking. This system is called Integrated Lens Manufacturing (ILM) and can manufacture IOLs and contact lenses with several times the efficiency and precision of normal methods.

Initiated research to develop an automated wet packaging process and high volume molding process for Extreme H2O lenses. The wet process went into production in the fall of 2002. The molding process began production April 2003. Our research and development effort initiated in 2001 has resulted in a complete cast molded lens manufacturing operation for Hydrogel Vision Corporation less than 2 years later here in Sarasota, Florida, USA.

2002   Developed new process technology called ES which results in more durable G-materials. Developed the first commercial 70% water content soft lens material that remains 100% saturated and dimensionally stable On The Eye. This product, called Aqua 70, is made with ES technology.

2003   Developed the first commercially available high quality bimodulus lens materials for both IOL and contact lens applications. Introduced ILM2, the second generation of Integrated Lens Manufacturing System for fabrication of custom contact lenses, including toric designs. This research and development effort has resulted in a further increase in speed and productivity of ILM.

2004   Validated the entire ILM-2 automated contact lens manufacturing system to be compliant with ISO 13485: 2003 standard requirements from blanks to finished lens. This is a state of the art manufacturing system available "turn-key" to our customers.

2005   Introduced Benz-G 72-HW, a 72%water G-material to replace lidofilcon (NAPALM) Polymers for high water applications. This is the first easily manufactured material in the 70+% water content range that does not contain N-vinylpyrrolidone. Introduced ILM-3, the second generation ILM for hydrophylic IOL manufacture.

2006-2007   Introduced Benz-G 4X 54% water G-material, a multi-modality capable high performance GMA hydrogel material designed for use as a molded lens as well as a custom lens. Introduced Benz Natural YellowTM, a unique compound utilizing nature's own UV-A blocker and violet light filter. Available in all IOL materials. Introduced ULtra O2 Plus, a third generation high water hybrid GMA soft lens material with a Dk of 50.
