The first systematic review of BVI Medical’s POD Double C-loop intraocular lens (IOL) platform has confirmed its high level of rotational stability across a range of lens types and materials. The review, co-authored by Sheraz Daya (UK), Christophe Chassain (France), and Christophe Pagnoulle (Belgium), and published in Clinical Ophthalmology, synthesizedd evidence from 19 clinical trials involving 1,428 eyes implanted with POD platform IOLs – both monofocal and trifocal, toric and non-toric, and manufactured in hydrophilic or hydrophobic acrylic – and analyzed at different follow-up periods.
Rotational stability is particularly critical in toric IOLs, where even small misalignments can compromise astigmatic correction. A 10° rotation can reduce the corrective effect by up to one-third, while some sources report that a rotation of over 30° can negate the correction entirely.
The POD Double C-loop design provides four-point contact with the capsular bag, offering a balance between adequate compression and stability without excessive tilt or axial displacement. While laboratory studies have previously suggested biomechanical advantages of this type of device, this review provides clinical confirmation.
The peer-reviewed studies examined in the review comprised the period 2013–2024, with follow-up periods being between one and 26 months, and IOLs including ANKORIS, PODEYE, PODEYE Toric, FINEVISION (POD F), FINEVISION Toric (POD FT), FINEVISION HP Toric, and the original POD AY 26P. While individual rotation values ranged between 1.18° to 5.84°, mean rotation across all studies was 2.61°, with nearly all lenses demonstrating rotations well under the clinically significant 5° threshold. The observed rotations typically occurred early, within the first ten days of surgery, and stabilized thereafter as the capsular bag contracted.
The Clinical Ophthalmology review confirms that the POD Double C-loop IOLs achieve exceptional stability, placing them on par with other leading platforms. For cataract and refractive surgeons, this translates into: high predictability of astigmatic correction with toric lenses; reduced need for secondary repositioning or enhancement procedures; consistent outcomes across designs and materials, including trifocal and hydrophobic lenses.
The findings reinforce the platform’s suitability as a foundation for next-generation premium lenses, including EDOF and adjustable optic technologies.
For further studies, the authors recommend researchers focus on the hydrophobic toric trifocal lens, as well as taking larger samples and studying longer follow-up periods extended to two years. They also highlight the importance of standardizing measurement methods, as discrepancies between slit-lamp, image analysis, and aberrometry can influence reported outcomes.
This landmark systematic review consolidates over a decade of evidence, showing that the POD Double C-loop haptic design delivers reliable long-term rotational stability. For study co-author Sheraz Daya at the Centre for Sight, London, this stability also means predictability for patients. “That translates into better, long-lasting vision without the need for secondary adjustments,” says Daya. “This study reinforces that our choice of lenses [at Centre for Sight] is the right one: they center well, hold their position, and provide the precision we promise. Patients benefit from fewer interventions, faster recovery and the confidence that their vision is in safe, expert hands.”
