A safe method of ciliary sulcus fixation of foldable intraocular lens using a ciliary sulcus guide

Repair of angle recession prevents pupillary capture of intrasclerally fixed intraocular lenses

PURPOSE

We evaluated a new concept for treating pupillary capture of the intraocular lens (IOL) following intrascleral fixation of the IOL. Pupillary capture of the IOL is a common postoperative complication that occurs after suturing and intrascleral fixation of the IOL. In such cases, blunt trauma is often related to zonular dialysis, iris retraction, iridodonesis, and angle recession. Several methods such as barricading by suturing, pupilloplasty, and pars plana fixation are reported to prevent pupillary capture. Although effective, none of these techniques fix iris-malposition and angle recession. We considered that repairing angle recession could correct the iris position and prevent pupillary capture recurrence.

METHODS

We repaired angle recession in four cases and have followed up.

RESULTS

Pupillary capture was not observed in all three cases of larger IOLs for more than 9 months, but observed after 1 month in an IOL with normal 6 mm diameter, in which the angle was not properly lifted.

CONCLUSION

In select cases, repairing angle recession may be useful for preventing pupillary capture after IOL suturing and intrascleral fixation.
