Purpose: AcrySof IQ Vivity is a unique non-diffractive extended depth of focus intraocular lens with wavefront-shaping X-WAVE technology. This study evaluated the cost-effectiveness of AcrySof IQ Vivity intraocular lens (DFT015) compared with standard aspheric monofocal intraocular lens (SN60WF), from a private health fund perspective in Australia.
Methods: A Markov model was developed using the following health states: well, need for spectacles (near/distance/bifocal/varifocal), very bothersome visual disturbances (glare/haloes/starbursts) - with/without spectacles, and death. Model inputs were sourced from a randomized clinical study (NCT03010254), published literature, prostheses list and clinical opinion. A lifetime horizon (up to 30 years) was considered, and cost and health outcomes were discounted at 5% per annum. Model outcomes included incremental cost-effectiveness ratio defined as incremental cost per quality adjusted life year gain. Sensitivity and scenario analyses were also conducted.
Results: Bilateral implantation of DFT015 intraocular lens provided quality adjusted life year gain of 0.16 at an incremental cost of AU$307 compared to bilateral SN60WF, leading to an incremental cost-effectiveness ratio of AU$1908/quality adjusted life year, well below the cost-effectiveness threshold (Range: AU$45,000-AU$75,000) typically used by Medical Services Advisory Committee in Australia. Results were most sensitive to intraocular lens costs, post-operative spectacle dependence, and disutility due to wearing glasses. Robustness of the results was further confirmed by probabilistic sensitivity analysis and scenario analyses.
Conclusion: AcrySof IQ Vivity intraocular lens is a highly cost-effective treatment strategy with improved vision-related quality of life outcomes for presbyopic cataract surgery patients.
