Purpose

Implantation of a monofocal intraocular lens is the current gold standard in cataract surgery, rending patients dependent on glasses after surgery. New implants with enhanced depth of focus could improve intermediate and near visions with uncompromised far visual acuity and limited dysphotpsia.

The objective of this prospective study was to compare a bilateral implantation of an extended depth of focus intraocular lens - Isopure® - versus a bilateral monofocal intraocular lens with same material and basic design - Micropure® - (PhysIOL, Belgium). 

Setting

This multicentric study was conducted in two university hospitals in Brussels, Belgium.

Methods

Eligible patients with bilateral cataracts were randomly assigned to two groups. Monocular and binocular, corrected and uncorrected, near (40cm), intermediate (80cm) and far (4m) visions were measured before and after their operations using ETDRS charts. A pre- and postoperative questionnaire was realized in order to assess the impact of their vision on their daily tasks.

Results

This prospective, randomized, double-blind study included 8 patients in the Isopure® group and 10 patients in the Micropure® group. Near and intermediate visual acuities were found to be significantly better in the Isopure® group. Near visions was respectively 0.27 ± 0.13 and 0.50 ± 0.13 LogMar (p-value=0.0037) while intermediate vision was 0.02 ± 0.08 and 0.21 ± 0.08 LogMar (p-value <0.001). No significant difference was demonstrated in the corrected monocular far vision (p-value 0.5490 and 0.1194). The questionnaires showed that patients in the Isopure® group had significantly fewer difficulties with daily activities including more independecy of their glasses. The overall questionnaire satisfaction was equivalent in both groups.

Conclusion

The Isopure® intraocular lens significantly improved intermediate and near vision while providing daily visual comfort, compared to its Micropure® homolog.
