Purpose

To evaluate the visual and refractive outcomes, vi­sual quality, patient satisfaction, and spectacle independence after phacoemulsification with bilateral implantation of a dif­fractive extended depth of focus (EDOF) intraocular lens (IOL).

Setting

Magrabi Eye Center, Jeddah, Saudi Arabia.

Methods

The study sample comprised 36 consecutive patients (72 eyes). Twenty-four (66.7%) patients underwent refractive lens exchange and 12 (33.3%) underwent cataract surgery. Exclusion criteria included previous ocular surgery, corneal higher order  aberrations of greater than 0.5 μm, and corneal astigma­tism of greater than 2.00 diopters (D). The dominant eye was targeted for emmetropia and the nondominant eye for -0.4 D. Uncorrected distance visual acuity (UDVA) and distance-corrected visual acuity were measured at 4 m and 66 and 40 cm. Patient satisfaction was assessed with a subjec­tive questionnaire at 3 months postoperatively. A P value of less than .05 was statistically significant. Follow up rate at 3 months was 92%.

Results

At 3 months postoperatively, the mean manifest refractive spherical equivalent was -0.32 ± 0.45 D. Binocu­lar UDVA at 4 m and 66 and 40 cm was -0.00 ± 0.09, 0.08 ± 0.10, and 0.23 ± 0.10 logMAR, respectively. Binocular defocus curves presented two peaks of -0.02 and 0.07 logMAR for 0.00 and -1.00 D defocus, respectively. The Objective Scatter Index score was 1.29. Mesopic contrast sensitivity with and without glare was within normal limits at lower frequencies (1.5 and 3 cycles per degree [CPD] and significantly lower at higher frequencies. No patient needed spectacle correction for intermediate vision while 24 (66.7%) patients needed spectacles for near vision. All patients were satisfied or very satis­fied with the postoperative outcome.

Conclusions

Bilateral implantation of a diffractive EDOF IOL resulted in good visual performance and spectacle independence for far and intermediate distances with high patient satisfaction at 3 months postoperatively.
