Abstract Details

Purpose:

To compare clinical outcomes after cataract surgery with implantation of a monofocal or an extended-range-of-vision (EDOF) intraocular lens (IOL).

Setting:

Hospital da Luz, Lisbon, Portugal

Methods:

Patients who had previously undergone myopic laser in situ keratomileusis (LASIK) had cataract surgery with bilateral implantation of an extended-range-of-vision intraocular lens (Tecnis Symphony) or a monofocal IOL (Tecnis ZCB00). Visual acuity, refraction, defocus curve, contrast sensitivity, photic phenomena, spectacle independence, and patient satisfaction were evaluated at 4 months postoperatively.

Results:

The study comprised 44 patients with 22 patients in each IOL group. No significant diferences were found for most parameters (all p > 0.27). Binocular uncorrected intermediate and near visual acuities were significantly better in the EDOF group (p<0.01). The defocus curves both IOLs differed more with increasing negative defocus (p<0.01). No significant diferences were found in contrast sensitivity (p>0.05). Mild glare was reported in 22,7% in the EDOF group, in 9,1% of the monodical group. Mild haloes was found in 13,6% of patients in both groups. Spectacle independence for intermediate an near vision was higher in the EDOF group.

Conclusions:

The extended-range-of-vision IOL was a useful option to restore visual function after cataract surgery in eyes that previously had myopic LASIK surgery, offering levels of visual quality comparable to those achieved with the monodical IOL.
