Evaluation of Fluid-Driven Lens Delivery System for Injectable Silicone-Oil-Filled Accommodating IOL
Narrative Responses:
Purpose
To evaluate the efficacy of a novel fluid driven delivery system for a silicone oil filled accommodating IOL (AIOL) in which the lens comes pre-loaded and can be auto-loaded into the injector tip for delivery
Methods
Thirty patients were enrolled in this prospective, single-arm study of the FluidVision AIOL (PowerVision, Inc., Belmont, CA). Lens loading and delivery efficacy was subjectively assessed by surgeons participating in the clinical evaluation of the AIOL. Lens delivery was considered successful if the lens delivered, dialed into the capsule and the patients recovered visual function. Follow-up visits occurred at weeks 1 and 2, and months 1, 3, 6 and 12.
Results
All 30 AIOLs were successfully delivered into 30 eyes of 30 patients. Video of the auto-loading and delivery demonstrates the ease of use. At the 6 month follow up the mean BCDVA was logMAR -0.04 (s.d. 0.04) and the mean DCNVA was logMAR 0.20 (s.d. 0.08). 100% achieved accommodation by defocus of 3.0 D or greater. There were no adverse events. These results support the efficacy of the novel fluid driven lens delivery system. (to be updated in January 2014)
Conclusion
: The silicone oil filled IOL requires a novel fluid driven lens delivery system. The delivery system with the auto-loading lens carrier was easy to use. The clinical evaluation, lack of adverse events and excellent visual acuities support the efficacy of the fluid driven lens delivery system.
