PURPOSE: To develop a selection pathway to facilitate the use of multifocal intraocular lenses (mfIOLs) in cataract surgery in a public hospital setting.
METHODS: A single-surgeon prospective cohort study in an Australian tertiary referral public hospital was conducted. A mfIOL selection pathway was designed and assessed. Outcomes measured included unaided distance (UDVA), intermediate (UIVA) and near visual acuity (UNVA), dysphotopsia, spectacle dependence and satisfaction. Patient-reported outcome measures (PROMs) were assessed using Catquest-9SF (CQ) and Near Visual Acuity Questionnaire (NAVQ). A cost-analysis was performed.
RESULTS: Fifty-four eyes from 27 patients underwent cataract surgery with mfIOL implantation. The monocular UDVA (mean ± standard deviation) was 0.05 ± 0.12 logMAR; UIVA 0.19 ± 0.05 logMAR; UNVA 0.28 ± 0.14 logMAR; 87% and 98% of eyes achieved within 0.5D and 1.0D of target refraction respectively. Spectacle independence was 85% at distance, 81% at intermediate, 59% at near vision. High satisfaction was reported with CQ (>85%) and NAVQ (100%). The cost difference between bilateral monofocal and mfIOLs is comparable to a pair of spectacles. Projected annual cost to the health system for a 5%-10% eligibility rate is 1.1-2.3 million Australian dollars.
CONCLUSION: The selection pathway presented overcomes the challenges in patient selection inherent to a public hospital setting and was implemented by a senior trainee with excellent vision and PROMs. The pathway ensures the cost-effectiveness of mfOL implantation. There are several funding models that can be applied to support equitable access and improved visual outcomes with mfIOLs within the government funded health system.
