However, designing successful accommodating IOLs remains daunting, said Julian Stevens MRCP, FRCS, FRCOphth, DO of Moorfields Eye Hospital. Several mechanical and flexible gel lens IOL designs have lost accommodative range over time due to capsule fibrosis, and lens mineralisation has developed as much as five years after implant, he noted. Detecting such problems lengthens development time, but is necessary, Dr Stevens added. “Given that we are implanting these lenses in younger people for refractive reasons, how much safety and efficacy data do you need, how long do you wait before you say ‘yes, that’s it?’” He believes electronic accommodating IOLs will be the solution, though battery technology must improve to provide a 40- to 50-year lifespan. Alcon are making progress on electronic accommodating IOLs and contact lenses, noted Laurent Attias, senior vice president for corporate development at the Novartis division. “The battery technology is not that far off. … we’ve seen improvements from four years to 20 years.” MK Raheja, head of ophthalmic implant R&D for Johnson & Johnson, is not willing to write off mechanical and shape-changing designs. Every technology has its advantages and limits and all are at an early stage, he said. “We need to push forward on every front.”
