Visual outcomes and patient satisfaction after bilateral implantation of an enhanced monofocal intraocular lens: a...

To evaluate and compare the visual outcomes of an enhanced monofocal intraocular lens (IOL) with two different monofocal IOLs.

Eye Clinic, Department of Medicine, Surgery and Health Sciences, University of Trieste, Trieste, Italy.

Prospective, single-center, single-masked, randomized controlled clinical study.

The study included patients undergoing phacoemulsification and IOL implantation. Patients were consecutively randomized by block randomization and assigned in a 1:1:1 allocation ratio to three study arms to bilaterally receive Tecnis Eyhance™ (model ICB00) or Tecnis^® monofocal 1-piece (model PCB00) or Clareon^® monofocal (model CNA0T0), respectively. Monocular and binocular (both corrected and uncorrected) visual acuities for far, intermediate and near were registered and compared among groups at 3 months. To track changes in patient quality of life, the Catquest-9SF questionnaire was administered to each patient before and after cataract extraction.

Ninety patients (30 for each group) were enrolled. At 3 months follow-up, statistically significant differences for intermediate visual acuities were found between the three groups. Nonstatistically significant differences were observed for distance visual acuities and the changes in Catquest-9SF scores.

Tecnis Eyhance™ provided better results in intermediate visual outcomes without adverse effects on patients' quality of life.
