Our Patent Portfolio

In March 2019, BHVI engaged Dr Arthur Back as its head of technology. Working with Dr Arthur Ho, Professor Padmaja Sankaridurg, Hassan Esfandiarijahromi and a team of optometrists and vision scientists, Dr Back has breathed new life into BHVI’s patent portfolio.

US Patent 11,061,253 B2 (Ophthalmic lenses for reducing, minimizing, and/or eliminating interference on in-focus images by out-of-focus light) was published in July 2021. The work of Dr Arthur Back and Hassan Esfandiarijahromi, the abstract describes it as:

An ophthalmic lens comprising: at least one first optical zone with a first axis, the at least one first optical zone being configured such that, in use with an eye, at least a portion of light passing through the at least one first optical zone is refracted to a first focal point on the first axis; and at least one second optical zone configured such that, in use with the eye, at least a portion of light passing through the at least one second optical zone is refracted to one or more focal points positioned off-axis relative to the first focal point and on at least one focal plane different than a focal plane corresponding to the first focal point; wherein the at least one second optical zone is configured such that the light extending beyond the one or more focal points provides extended depth of focus.

It supports a new generation of contact lenses, spectacle lenses and IOLs that may reduce and/or eliminate the effects of optical disorders including myopia and presbyopia.

Other applications and PCTs filed during Dr Back’s tenure encompass:

  • Geometrically defined shapes and/or contour optical elements for ophthalmic lenses and methods for creating such geometrically defined shapes and/or contour optical elements
  • Ophthalmic Devices, systems and/or methods for management of ocular conditions and/or reducing night vision disturbances
  • Ophthalmic lenses and methods for correcting, slowing, reducing, and/or controlling the progression of myopia in conjunction with atropine or related compounds
  • Intraocular Lenses for Reducing Peripheral Pseudophakic Dysphotopsia
  • Ophthalmic Devices, systems and/or methods for management of ocular conditions and/or reducing night vision disturbances
  • Ophthalmic Lenses using Binary Amplitude Modulation
  • Pharmaceutical Compositions and/or methods for Presbyopia, Mydriasis and/or ocular discomfort management
  • Pharmaceutical Compositions For Controlling And/Or Reducing The Progression Of Myopia
