Tekia accommodating intraocular lens

The relatively long length and radius of distal portion 20 provides greater contact with the capsular bag for better fixation when IOL 10 is implanted in the eye.

Elbow 18 creates a hinge allowing haptic 14 to flex while minimizing buckling and vaulting of optic 12.

Alternatively, gusset 16 or optic 12 may be provided with other means (such as holes, grooves, notches, micro-fenestration, or protuberances (all not shown)) to facilitate fluid flow between posterior side 26 and anterior side 24 of IOL 10.

Distal portion 20 may have a length L of any suitable dimension, but between 4.00 mm and 5.00 mm is preferred with 4.65 mm being most preferred.

Haptics 14 contain gusset 16, elbow 18 and distal portion 20 having widened portion 22. 2, the thickness T of elbow 18 and distal portion 20 of haptic 14 is uniform, and preferably between about 0.30 mm and 0.60 mm, with between about 0.40 mm and 0.50 mm being more preferred and about 0.43 being most preferred.

Several new intraocular lenses (IOLs), called multifocal and/or accommodating IOLs, have been introduced in recent years that utilize advanced technology to achieve good distance, intermediate and near vision without glasses.

Prior to the present invention, however, single piece soft IOLs designs have been limited to plate designs (see e.g., U. Therefore, a need continues to exist for a single piece, soft, foldable IOL with an open loop haptic design.

The present invention improves upon the prior art by providing a single piece soft foldable IOL having open loop haptics of specific thickness and geometry.

These and other advantages and objectives of the present invention will become apparent from the detailed description and claims that follow.

of any suitable dimension, with between 10.5 millimeters (mm) and 14.0 mm being preferred and 12.5 mm being most preferred.
