Preloaded injector falls short in providing safe, predictable IOL delivery
A preloaded IOL injection system failed to provide safe and predictable IOL insertion, according to a study.
The prospective study included 85 eyes of 85 patients who underwent phacoemulsification; patients’ mean age was 73.1 years. All eyes received an AcrySof IQ SN60WS single-piece 6-mm hydrophobic acrylic IOL (Alcon) preloaded and delivered with Alcon’s AcrySert injector system.
Correct IOL insertion was achieved in 38 of 85 eyes (45%). Additional rotational manipulation was required in 47 eyes (55%). Average time to attain satisfactory IOL position was 47 seconds, according to the study.
Problems associated with injection included trapped trailing haptics, haptic-optic adhesion, the plunger over-riding the optic and trauma to the optic edge.
Proper IOL centration in the capsular bag and sutureless wound closure were achieved in all cases; no intraoperative complications were reported.
Further refinement is necessary to improve delivery characteristics in order to benefit from the potential advantages of a preloaded IOL system, the authors said.
