Purpose: : To evaluate the variation in delivery characteristics and predictability of the injectable Alcon AcrySof IQ SN60WS intraocular lens (IOL) delivered via a preloaded AcrySert delivery system.

Methods: : A prospective observational case series of 85 eyes undergoing elective phacoemulsification and IOL implant. Analysis was made of the digitally captured IOL delivery stage of the procedure.

Results: : In 36 of the 85 eyes (42%) delivery of the IOL was achieved uneventfully without the need for additional manipulation of the IOL orientation during its delivery. 49 of the 85 cases (58%) required manipulation of the orientation of the IOL during the progress of the IOL delivery, usually via an appropriate rotational movement of the injector nozzle itself while positioned in the main cornea wound. In 34 of these cases the leading haptic repeatedly presented into the anterior chamber orientated to the right, requiring a 180 degree rotation in order to correct the misdirection. On 4 occasions, following leading haptic misdirection in each case, the final IOL orientation was inverted 180 degrees, although centred in the capsular bag. In 6 of 85 cases (7%) the trailing haptic became trapped in the syringe nozzle requiring an additional action in order to deliver the IOL satisfactorily. Other events witnessed were haptic-optic adhesion (1) and overriding of the syringe plunger over the entire optic (1). The average time to achieve satisfactory capsular bag IOL position was 47 seconds. IOL power and the grade of operating surgeon did not appear to influence the important event of a misdirected leading haptic in this series.

Conclusions: : In its present form, the preloaded AcrySof IQ SN60WS AcrySert IOL system does not demonstrate predictable IOL delivery character, commonly requiring significant intra-wound manipulation of the injector in order to complete safe IOL delivery. In order to benefit from the potential advantages of a preloaded IOL system, further refinement is required.
