Abstract Details

Purpose:

To demonstrate Precisight Multicomponent IOL Implantation Trough Micro Incision Less Than 1.6 mm Cataract Surgery.

Setting:

Novavision Laser Center, Mexico City.

Methods:

After phacoemulsification, a 1.5mm injector was used to inject the two optical elements of multicomponent PrecisightTM lens system, a 14 diopter base lens and a 7 diopter front lens. The lenses were then assembled in the anterior chamber by inserting the tabs of the front lens into openings (“bridges”) projecting off the anterior surface of the base lens. The assembled, 21 diopter, lens was positioned such that the haptics of the base lens were in the bag the tabs of the front lens were in front of the rhexis (capsule opening).

Results:

The intraocular lens assembly was easily accomplished. The location of the front lens outside the capsule has enabled the exchange of the front lens component where undesirable refracting results were found after the primary cataract procedure. Injecting the lenses separately takes a few minutes more surgical time since with routine 2.2mm incision surgery, the PrecisightTM lenses are injected having been preassembled, but this separate injection technique allows, theoretically, for incisions as small as 1.3mm.

Conclusions:

The PrecisightTM lens system has several advantages over other single or multicomponent systems. By splitting the dioptric power thickness in two components, we demonstrated that the lens can be injected through a 1.5mm injector. In addition, the front lens is easily exchangeable at any time for refractive adjustments. Finally, because there are two optical elements, by placing the toric correction in one component and the spherical correction in the second component, a small inventory of components allows refractive customization.
