Abstract Details

Purpose:

To assess any changes in incision size and wound architecture when comparing two intraocular lens injector systems

Setting:

Sussex Eye Hospital, Brighton, England

Methods:

A consecutive case series of 40 eyes of 40 patients undergoing standard cataract surgery with IOL implantation. A single surgeon (MAN) performed all surgeries using a 2.2-mm incision and phacoemulsification. All patients received a C-flex Aspheric 970C IOL, using either a RaySert PLUS (Rayner Intraocular Lenses Limited, UK) or the Accuject injector (Medicel AG, Switzerland). The main wound was objectively measured using standardized wound gauges (Duckworth & Kent, UK) at three points during surgery: 1) before insertion of the phacoemulsification probe 2) prior to intraocular lens insertion and 3) post IOL insertion. Leakage of the wound was assessed using 2% fluorescein eye drop (Minims, Bausch+Lomb, Rochester, NY). Following the procedure the surgeon's subjective assessment of the two injector systems was obtained on a four-point Likert scale assessing a number of parameters.

Results:

The study compared several parameters related to the injector system performance: 1) ease of IOL loading into the injector; 2) ease of advancing the IOL into the loading bay and nozzle; 3) the force required to push the IOL through the nozzle; 4) the ease of incision entry, and; 5) the ease in which the IOL exited from the nozzle. These parameters were graded from 1 to 4 with 1 as ‘very difficult'; 2 - ‘difficult'; 3 - ‘easy' and 4 - ‘very easy'.

Conclusions:

Both IOL injector systems provide a safe and effective method of implanting the IOL into the bag during standard cataract surgery. A surgeon's subjective assessment of IOL injector systems should also be taken to into account when determining appropriate manufacturers and will be presented. Further evaluation of a number of injector systems within an NHS setting, would be worthwhile.
