Diagonal haptic capture of a plate intraocular lens with 4 haptics

摘要

A technique of diagonal haptic capture of a plate intraocular lens (IOL) with 4 haptics for cases with insufficient posterior capsular support is presented. The diagonal haptics were captured through the capsulorhexis by sequentially depressing each side of the haptic beneath the rim of the capsulorhexis with a gentle pressure. The IOL is fixated by pure IOL-capsule capture without sulcus fixation of haptics. The technique was used in 12 eyes (12 patients). The IOLs were well centered within the follow-up period. No IOL malposition, pseudophacodonesis, pupil capture, pigmental dispersion, or high intraocular tension was observed postoperatively. Ultrasound biomicroscopy revealed that there was no chafing of the IOL with the posterior iris. The technique provided an instant and definitive fixation with high adaptability to different sizes of capsulorhexis, and thereby could reduce the risk for complications related to haptic-sulcus fixation.
