Purpose
To compare the visual outcomes, spectacle independence and patient satisfaction of bilateral implantation of either monofocal plus IOLs (Eyhance ICB00) or standard aspheric monofocal IOLs (Alcon SN60WF), using a micro-monovision technique.
Setting
University Hospital, London, United Kingdom.
Methods
Patients with bilateral cataracts and corneal astigmatism of less than 1.50 dioptres, and no other significant ophthalmic co-morbidities were randomised to receive either bilateral insertion of Alcon SN60WF or the Eyhance ICB00 IOL with micro-monovision. The refractive target of the dominant eye was 0.00 to -0.25D, with the target of the myopic eye -0.75 to -1.00D. Patients were reviewed at 2 weeks, 6 weeks and 6 months. Primary outcomes were vision, contrast sensitivity, stereoacuity and patient satisfaction.
Results
Sixty-four patients were randomised to the Alcon SN60WF group (21M:43F, mean age 69.08 yrs), and Sixty-six patients to the Eyhance ICB00 group (23M:43F, 67.18 yrs). At 6 weeks mean unaided distance vision of the emmetropic eye in the Alcon group was 0.06 logMar (-0.16 to 0.44), and 0.08 (-0.18 to 0.54) in the Eyhance group (p=0.25). Mean unaided near vision of the myopic eye was 0.36 logMar in the Alcon group (0.1 to 0.72), and 0.25 in the Eyhance group (-0.1 to 0.52) (p<0.05). In the Alcon group 66% (42 patients) used reading glasses after surgery, compared to only 21% (14 patient) of the Eyhance group (p<0.0001). There were no statistically significant differences in contrast sensitivity, stereovision and patient reported outcomes.
Conclusions
More patients in the Eyhance ICB00 group achieved spectacle independence for distance, intermediate and near than the Alcon group with micro-monovision implantation. This supports the use of the Eyhance IOL in public health sector patients to reduce their dependence on spectacles following cataract surgery. We aim to present further data, with larger groups and 6-month follow-up data.
