Single-action Implantation of SA60AT with Monarch II ®

Abstract

Purpose

The authors have invented a method to implant the AcrySof^® model SA60AT intraocular lens (IOL) with a single action to avoid complications in the recommended method.

Methods

After inversely inserting the SA60AT into the Monarch II^® cartridge, the optic of the SA60AT is held with IOL forceps and rotated 90° counterclockwise. At this point, the haptics of the SA60AT are placed on the upper side of the optic within the cartridge. Next, the cartridge is inserted into the anterior chamber, and the main body of the Monarch II^® injector rotated by 180° prior to pushing the plunger gradually. Once the front area of the SA60AT is inserted into the capsular bag, the remainder of the SA60AT can be slowly injected into the capsular bag. Aspiration of viscoelastic substances enables the haptics to expand in the capsular bag. The authors examined the complications in the invented method.

Results

The authors successfully implanted the SA60AT into the capsular bag in 226 consecutive patients (170 patients with cataract surgery alone and 56 patients with combined vitreous surgery) using the single-action method without any complications.

Conclusions

The method is simple and useful for the implantation of SA60AT with Monarch II^® injector.
