Abstract
Purpose
To evaluate the rotational stability of the Acrysof Toric intraocular lens (IOL) after experimental eye trauma.
Methods
Two human cadaver eyes were prepared in accordance with the Miyake–Apple technique, with closed-system modification. After phacoemulsification, an Acrysof Toric IOL was implanted in the capsular bag. Experimental traumatisation of the globe was achieved by pressing against the eye wall using a cotton tip or a fingertip, whereas the IOL was observed from the posterior view. Digital photographs of the eye before and after the procedures were overlaid to detect and measure rotation of the IOL.
Results
The IOL rotated 5.80° when the traumatic procedures did not cause important leakage from the incision. When the traumatic procedures caused important leakage from the incision and anterior chamber collapse, the IOL rotated 41.00°.
Conclusion
Ocular trauma can cause rotation of the Acrysof Toric IOL. In the event of an eye trauma with no or insignificant leakage from the incision, the IOL rotates less than when the trauma causes significant leakage from the incision.
