Narrative Responses:

Purpose
Retrospective clinical evaluation of clear lens exchange procedures with implantation of multifocal and toric-multifocal intraocular lenses (IOLs).

Methods
In this single centre retrospective evaluation 75 eyes with clear lens exchange and diffractive-apodized multifocal IOL implantation and 26 eyes with diffractive-apodized toric-multifocal IOL implantation (Restor, Alcon) were included. Measured outcomes include accuracy of IOL calculation (intended versus achieved refraction) and functional outcomes for distance and near using ETDRS charts.

Results
Altogether 101 eyes of 55 patients were included in the analysis. Mean age was 57.7 ± 7.7 years in the multifocal and 54.1 ± 4.3years in the toric-multifocal group. Spherical equivalent IOL power ranged from +7.5 to +28.5 D and +10.5 to +29.5 D, respectively. The toric power ranged between 1 and 3 D cylinder. Uncorrected distance visual acuity (UDVA) at 3-6 months postoperatively was 0,13 ± 0,12 logMAR (multifocal group) and 0,20 ± 0,16 logMAR (toric-multifocal). Uncorrected near visual acuity (UNVA) at 3-6 months postoperatively was 0,09 ± 0,13 logMAR and 0,14 ± 0,15 logMAR, respectively.

Conclusion
The clear lens exchange procedures were uneventful in all cases and resulted in high patient satisfaction with significant improvement of uncorrected near and distance visual acuity. Toric multifocal IOLs were helpful in reducing remaining postoperative refractions.
