Wound Integrity of 2.0 mm Transconjunctival Single-Plane Sclerocorneal Incision: A Comparison between a Motorized Injector with/without Pause Time and a Manual Injector

Purpose. to compare the final incision size and wound structure after the intraocular lens implantation from 2.0 mm transconjunctival single-plane sclerocorneal incision (tssi) between the use of a motorized injector at first speed and the use of a manual injector. methods. patients were divided into three groups as follows: group a,a manual injector,group b,a motorized injector with 0.5 s pause time,and group c,a motorized injector without pause time. the change in incision size and anterior segment optical coherence tomography findings of the wound structure were analyzed. results. 110 eyes were enrolled (group a: 40,group b: 30,and group c: 40). the averaged change in incision size (mm) was 0.08,0.01,and 0.03 in groups a,b,and c,respectively (p<0.001). the incision enlargement in group a was statistically larger compared with other groups (p<0.01). descemet's membrane detachments were seen in 26,9,and 27 eyes one day after the surgery in groups a,b,and c,respectively (p=0.001). the rate of descemet's membrane detachment in group b was significantly lower than other groups (p<0.01). conclusions. the use of a motorized injector by fastest setting with 0.5 s pause time is the best for less wound damage in 2.0 mm tssi. copyright © 2016 hisanori imai et al.
