Purpose
To compare the enlargement of the clear corneal incision during cataract surgery from IOL implantation with two different preloaded intraocular lens (IOL) injectors: the AutonoMe injector preloaded with the Claron IOL (Alcon Laboratories, Inc) and the Multisert injector preloaded with the Vivinex IOL (Hoya
Setting
This prospective, randomized, intraindividual comparative clinical study was conducted at a university eye clinic in Germany
Methods
96 eyes of 48 cataract patients were intraindividually randomized to treatment with one of the two IOL injector models. In the eyes in which the Multisert injector was used, the insert shield, a design feature limiting injector advancement, was used in 23 randomly selected eyes. Intraoperative measurement of the incision size was performed before and after phacoemulsification and after IOL injection. The initial incision size was 2.2 mm for both injectors. At the 3-months follow-up visit, keratometry, subjective refraction and visual acuity were assessed.
Results
Mean incision enlargement was 0.213 ± 0.068 mm in the Multisert group treated with insert shield and 0.265 ± 0.055 mm in the fellow eyes treated with the AutonoMe injector (
P < .05). Mean incision enlargement in Multisert eyes treated without insert shield was 0.272 ± 0.060 mm and 0.296 ± 0.066 mm for the fellow eyes (AutonoMe) (
P > .05).
The mean absolute surgically induced astigmatism (SIA) was 0.42 ± 0.23 diopters (D) in the Multisert with shield group and 0.50 ± 0.25 D for the Multisert without shield group. For the AutonoMe group, mean SIA was 0.44 ± 0.18 diopters D. Differences between groups were not statistically significant (P >.05).
Uncorrected (UDVA) and corrected distance visual acuity (CDVA) were comparable in all groups.
Conclusions
The Multisert injector was associated with less corneal incision enlargement. Eyes treated with insert shield showed significantly lower wound enlargement than patients treated without the insert shield. Despite the differences in incision enlargement, functional outcomes including SIA, UDVA and CDVA were comparable in all groups.
