Purpose
To compare postoperative visual outcomes between the RayOne EMV intraocular lens and the RayOne monofocal intraocular lens in a large real-world cataract surgery cohort.
Setting
Spamedica and Freedom Vision Hospitals
Methods
A retrospective multicentre dataset analysis of 5654 eyes undergoing cataract surgery with Rayner intraocular lenses. Eyes implanted with RayOne EMV lenses (including toric models) were compared with eyes implanted with RayOne monofocal lenses. Propensity score matching was performed using preoperative uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corneal astigmatism derived from keratometry, and axial length to generate balanced comparison cohorts. Postoperative UDVA, CDVA and visual acuity improvement were compared between groups. Multivariable regression analysis was used to evaluate the independent association between intraocular lens type and postoperative visual outcomes.
Results
Propensity matching generated balanced cohorts of 533 eyes in each group with good baseline balance across all matching variables (standardised mean differences <0.15). Postoperative UDVA was lower in the RayOne EMV group compared with RayOne monofocal lenses (mean logMAR 0.153 vs 0.086), with a smaller improvement in UDVA (0.351 vs 0.452 logMAR, p < 0.001). There was no significant difference in postoperative CDVA between groups (0.056 vs 0.052 logMAR, p = 0.68).
Conclusions
In this large real-world cohort, implantation of the RayOne EMV intraocular lens was associated with lower postoperative uncorrected distance visual acuity compared with a conventional monofocal RayOne lens, while maintaining equivalent corrected distance visual acuity. These findings are consistent with the optical design of extended-range intraocular lenses, which prioritise increased depth of focus and functional vision at intermediate distances.
