Intra and Postoperative Outcomes With 3 Injectors

In this randomized, clinical trial, three types of injectors were compared :

• Manual, screw type injector (Monarch III)
• Manual, plunger type injector (Royale, ASICO)
• Motorized injector (Autosert, Alcon)

Having performed a phacoemulsification through 2.2mm incision, IOL implantation was performed using a D cartridge and one of three injectors which was decided in a randomized fashion.

The investigators evaluated incision enlargement at following points : at the end of phacoemulsification, and then, at the end of IOL implantation The investigators also looked at trypan blue ingress into the anterior chamber from the ocular surface. At 1 day, 1 week, and 1 month after surgery anterior segment OCT morphology was also studied.

further, the surgeon was asked to subjectively grade the ease of implantation with each injector
