Abstract Details

Purpose:

To evaluate the UltraSert™ pre-loaded IOL Delivery System through a surgeon evaluation questionnaire.

Setting:

Cataract Treatment Centre at Sunderland Eye Infirmary UK, and 7 other clinics in Europe

Methods:

13 surgeons in eight European countries evaluated use of the UltraSert™ device in 294 surgeries. Incision sizes just before and immediately following IOL delivery with the UltraSert™ were measured using callipers with 0.1mm increments. At the end of surgery, using a scale from 1 (Not at all) to 5 (Extremely), the surgeons ranked different features of UltraSert™: control of advancement, visibility, ease of placement of the leading haptic in the capsule bag during delivery, usefulness of the plunger extension after delivery and the overall effective performance of the UltraSert™.

Results:

The majority of the surgeons (88%) made incisions of 2.2 mm with a mean IOL dioptric power 21.3 ± 2.6 D. Results showed that pre-IOL delivery incision sizes were at 2.2 mm (43%) and 2.3 mm (41%). Post-IOL delivery surgeons reported a final incision size of 2.3 mm (52%), and 2.4 mm (34%). In most cases (65%), the incision enlargement was 0.1 mm, with a third of the cases experiencing no incision enlargement (32%). Overall, a majority of surgeons ranked UltraSert™ positively (3 – Somewhat to 5 – Extremely) with most falling in the 5 (Extremely) ranking.

Conclusions:

The results of this questionnaire showed the benefits of the UltraSert™ pre-loaded Delivery System features, such as the minimization of the incision stretch, thanks to the Depth Guard. Only 3% of patients have incision enlargement 0.2mm and none with >0.2 mm. More than 60% of the surgeons ranked the control of IOL advancement as extremely well managed, thanks to the TensionGlide™ Spring. The visibility of the IOL inside the injector was also ranked extremely well by 70% of the surgeons and almost half of the doctors considered the placement of leading haptic in the capsular bag during delivery extremely easy.
