We describe the technique of sealed capsule irrigation, which aims to reduce posterior capsule opacification and better control lens epithelial cell activity.

The Miyake-Apple technique for posterior photography and video analysis of postmortem eyes and its variations provide a unique view of the anterior segment structures and surgical manipulations that are not readily seen during surgical procedures or by clinical inspection. It is particularly useful in studying and teaching anterior segment surgery, especially cataract and intraocular lens (IOL) surgery. We summarize the peer-reviewed literature on the use of this technique (1) in experimental studies with fresh human or animal eyes to analyze new IOLs and surgical techniques, (2) in formalin-fixed human pseudophakic autopsy eyes to study IOL-related complications, and (3) for teaching and training purposes.

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 5.801 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 41.001. 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.
