Semi-flexible posteriorly vaulted acrylic intraocular lens for the treatment of presbyopia

A uniplanar intraocular lens comprising:

• a single-focus, semi-rigid acrylic optic, the optic being vaulted backwards;
• and
• a pair of semi-rigid, acrylic haptics connected to opposite sides of the optic, each haptic comprising a plate haptic,
• wherein the intraocular lens has a fixed longitudinal length, the fixed longitudinal length being measured from the distal end of one of the haptics to the distal end of the other of the haptics and along a longitudinal axis of the intraocular lens, the fixed longitudinal length being the same pre-operatively and post-operatively, such that the intraocular lens haptics resist deformation during contraction and relaxation of the ciliary muscle and fibrosis to maintain the optic in the same position along an optical axis of the eye, the fixed longitudinal length being between 9.5 mm and about 12 mm, the lens configured to provide uncorrected vision at near, intermediate and far distances without accommodation.

A non-accommodating intraocular lens comprising:

• a single-focus optic;
• and
• a pair of semi-rigid haptics connected to opposite sides of the optic,
• wherein the optic is pre-operatively vaulted posteriorly at a fixed angle relative to each haptic, the vault angle remaining unchanged after implantation, the vault angle being between 1 degree and 50 degrees, the lens configured to provide uncorrected vision at near, intermediate and far distances without accommodation,
• wherein the semi-rigid haptic is sufficiently flexible to be compressed from an original configuration to a compressed configuration for insertion into the eye through a small incision and sufficiently rigid to resist compression when subject to pressures by the ciliary muscles and fibrosis, the intraocular lens being configured to return to the original configuration after implantation, the original configuration being vaulted posteriorly at the fixed angle, and
• wherein an outmost lateral periphery of the haptics has a transverse dimension larger than that of the optic and surrounding at least a portion of the periphery of the optic and a lateral side of each haptic.

A non-accommodating intraocular lens comprising:

• a single-focus, acrylic optic;
• and
• a pair of acrylic haptics connected to opposite sides of the optic, each haptic having a proximal end and a distal end, the proximal end being closer to the optic than the distal end,
• wherein the lens optic is manufactured vaulted posteriorly at a fixed angle relative to each haptic, the vault angle remaining unchanged after implantation, the vault angle being between 1 degree and 50 degrees, the lens configured to provide uncorrected vision at a near, intermediate and far distances without accommodation,
• wherein the intraocular lens has a fixed longitudinal length, the fixed longitudinal length being measured from the distal end of one of the haptics to the distal end of the other of the haptics and along the longitudinal axis of the intraocular lens, the fixed longitudinal length being the same pre-operatively and post-operatively, such that the intraocular lens resists deformation during contraction and relaxation of the ciliary muscle and fibrosis to maintain the optic in the same position along an optical axis of the eye, the fixed longitudinal length between about 9.5 mm and 12 mm, and
• wherein the optic and the at least one haptic are monolithic.
