Abstract Details

Purpose:

The Vivity IOL is a non-diffractive, presbyopia correcting IOL that extends the depth of field through proprietary X-WAVE technology located on the anterior surface of the IOL. Visual disturbances are expected to be equivalent to a monofocal IOL. The purpose of the paper is to describe the performance of the Vivity IOL in a range of cases including prior refractive surgery, mild retinal disease and pre-existing monofocal IOLs in the contra-lateral eye.

Setting:

Patients undergoing cataract surgery and implant with the Vivity IOL at a private ophthalmic surgery centre.

Methods:

Retrospective review of consecutive patients undergoing cataract and lens-based surgery with the Alcon Vivity IOL. 11 patients representing the initial cohort undergoing cataract and IOL insertion with the Vivity IOL were included in the analysis. Aiming for mini monovision was targeted in some patients, while other were targeted for plano in both eyes. Routine preoperative demographic variables were collated. Data collected following surgery included visual acuity (distance, intermediate ~60cm and near ~40cm) and refraction. Patient selection and refractive endpoints will be discussed in the context of variables including age, concurrent ocular disease and patient expectations.

Results:

Mean age was 66 years (range 52 to 87) and 72.7% male. Mean preoperative spherical equivalent (SE) was -0.13 ± 1.76D. The predicted refractive endpoint ranged from plano to -1.0D. Three patients had prior surgery with an insertion of a monofocal IOL in the fellow eye. All patients requested optical independence for at least some daily activities. Uncorrected binocular distance vision was 6/7.5 or better in all cases. Binocular intermediate and near vision ranged from N4 to N12 in all cases (median value N8 and N6 for intermediate and near respectively). No patient described significant photic phenomena post-surgery.

Conclusions:

The current range of IOL options for surgeons to provide their patients is extensive. Utilising an IOL with an extended range, in the absence of significant photic phenomena may provide surgeons with a more appropriate and forgiving option allowing patients to maintain excellent distance vision whilst achieving a practical range of unaided near and intermediate vision. Further, this option may represent a valid option for patients not suitable for trifocal IOLs due to previous surgery or concurrent ocular disease.
