Abstract Details

Purpose:

To assess visual outcomes and patient’s satisfaction of multifocal and extended range of vision intraocular lenses (IOLs) in comparison to monofocal IOL implantation with and without monovision.

Setting:

Ein Tal Eye Center, Tel Aviv, Israel

Methods:

Consecutive patient’s records who underwent bilateral IOL implantation following cataract extraction surgery and had 1 month postoperative manifest refraction, were reviewed. Spectacle independence, patient satisfaction, and photic subjective phenomena were analyzed using a questioner survey. Four groups of IOLs were selected: (1) extended range of vision IOL (ERVI), (2) trifocal IOL, (3) monofocal IOL, and (4) monofocal IOL using the mono-vision method.

Results:

The ERVI group comprised 38 patients; the other groups comprised 50 patients. Mean postoperative-uncorrected distant, intermediate and near visual acuities were: 0.07±0.10, 0.08±0.13, 0.23±0.15 (ERVI); 0.07±0.09, 0.08±0.11, 0.06±0.08 (trifocal); 0.17±0.14, N/A, N/A (monofocal); and 0.08±0.12, N/A, 0.07±0.12 (monovision). 95%, 96%, 48%, 80% of patients respectively, reported to be distant spectacles independent. 87%, 96%, 4%, 80% were spectacles independent for intermediate. 55%, 86%, 36%, 52% were spectacles independent for near. 13%, 38%, 2%, 6% of the patients reported experiencing postoperative halos/glare. 72%, 76%, 56%, 72% would choose the same IOL again.

Conclusions:

Trifocal IOLs are more effective at improving the whole range of vision, and patients reported more spectacles independent than those in the other groups. However, patients with trifocal lenses reported more glare and haloes. Patient satisfaction was high in all the groups but the monofocal group.
