Abstract Details

Purpose:

To evaluate the grade of tilt among patients undergoing femtosecond laser-assisted cataract surgery or clear lens exchange and determining possible connection with femtosecond laser-induced complications.

Setting:

International Vision Correction Research Centre (IVCRC), Department of Ophthalmology, University of Heidelberg, Heidelberg, Germany

Methods:

294 eyes of 200 patients were assessed. The intraoperative complications and the tilting angle of the cristalline lens while interface docking was evaluated. Therefore the optical coherence tomography (OCT) images provided by the LenSx femtosecond laser were used. On the OCT line scans the angle between a reference horizontal plane and the plane given by the two capsulotomy end points was measured.

Results:

Results yielded a mean angle of 2,93±2,25 degrees. As assessed, 181 eyes had a lens tilt of less than 3 degrees (1,50±0,87), 81 eyes between 3,01 and 6 degrees (4,22±0,86). 27 eyes showed a tilt between 6,01 and 9 degrees (7,33±0,91). In the case of 5 eyes a larger angle than 9 degrees (9,93±0,86) with the maximum value of 11,07 was obtained.

Conclusions:

At nearly two third of the evaluated eyes a tilt less than 3 degrees was measured. In only one tenth of the cases was the angle more than 6 degrees. Correlation between crystalline lens tilt and femtosecond laser-related complications, such as radial tear and posterior capsule rupture will be presented.
