OSN Europe: Endodiathermy marks useful in cases of postoperative toric IOL rotation
Imperative to the efficacy of all toric IOLs is the position of the IOL with regards to the intended alignment axis because every degree of misalignment leads to residual astigmatism. Misalignment of the IOL may be caused by either inaccurate placement or rotation of the IOL.Toric IOLs represent a significant advance in achieving optimal cylindrical and spherical refractions after IOL surgery and are the preferred method for correcting pre-existing astigmatism during cataract surgery. Accurate rotational stability and axial alignment of toric IOLs are critical to the efficacy of surgery. Each (Read more...)

Publication Exclusive: Correct technique, tools can optimize femtosecond surgery outcomes
Modern-day cataract surgery requires lysis of most, if not all, corticocapsular adhesions toward the outer lens surface and freeing cortical-nuclear attachments in the interior of the cataractous lens. Hydrodissection is utilized to shear corticocapsular adhesions, while hydrodelineation breaks the epinuclear-nuclear adhesions. These surgical steps will facilitate in-the-bag nuclear rotation, thus assisting in lens division and removal by the technique of the surgeon’s choice. Further, such separation of the cortex from the lens capsule will simplify cortical cleanup and help preserve an intact posterior lens capsule for in-the-bag IOL placement. Incomplete (Read more...)
