Specifications:
The document outlines the specifications of the EXTEND series of intraocular lenses (IOLs), including EXTEND SL, EXTEND BN, and EXTEND Toric. These lenses have a platform C-Loop design with an overall diameter of 13 mm or 11 mm, and an optic diameter of 6 mm. They are designed for placement in the capsular bag and have a power range of 10-30 diopters with 0.5 D increments. The cylinder range for astigmatism correction is -1.0 D. The lenses feature a modified aspheric optic design to extend the depth of focus, with the EXTEND Toric also providing astigmatism correction.

Material and Design:
The lenses are made from glistening-free hydrophobic acrylic with a UV blocker and a natural yellow violet light filter. They have a refractive index of 1.48 at 35°C and are sterilized using ETO. The lenses are available in a preloaded configuration.

Performance and Benefits:
The EXTEND IOLs are intended to provide distance vision similar to standard aspheric monofocal IOLs while enhancing intermediate vision, thus reducing spectacle dependence for intermediate tasks. The EXTEND Toric is specifically indicated for correcting regular corneal astigmatism.

Clinical Data:
A study involving 12 cataract patients (24 eyes) showed that the EXTEND lenses provide an extended depth of focus with far-dominant performance and functional intermediate vision. The binocular defocus curve was assessed three months post-surgery.

Conclusion:
The EXTEND series of IOLs offer an innovative solution for patients seeking improved intermediate vision and reduced dependence on spectacles, particularly for those with astigmatism.
