PURPOSE To evaluate the refractive and visual outcomes following cataract surgery and implantation of a new enhanced monofocal extended depth of focus (EDOF) intraocular lens (IOL). METHODS Fifty eyes of 25 consecutive patients who underwent implantation of the xact Mono-EDoF IOL (Santen Pharmaceutical Co, Ltd) were enrolled in this study. Main outcome measures were refractive error and monocular corrected (CDVA) and uncorrected (UDVA) distance visual acuity values. Monocular visual acuity at different vergences (defocus curve) was obtained. Patients were evaluated at 12 months postoperatively. RESULTS At 1 year of follow-up, all eyes showed a postoperative spherical equivalent within ±1.00 diopters (D) and 95% of eyes within ±0.50 D. The mean postoperative spherical equivalent was -0.15 ± 0.28 D. A total of 88% and 100% of eyes showed UDVA and CDVA of 20/25 or better, respectively. The mean values of UDVA and CDVA (Snellen decimal) were 0.94 ± 0.09 (range: 0.70 to 1.00) and 0.99 ± 0.03 (range: 0.79 to 1.00), respectively. Defocus curve showed good visual acuity at distance and intermediate distances with a depth of focus value of 1.25 D. No visual disturbances were reported in the whole sample during the entire follow-up. CONCLUSIONS The current study shows that this EDOF IOL provides good visual performance at far and intermediate distances. The lens may be considered for patients interested in reducing spectacle independence at intermediate distances. [J Refract Surg. 2021;37(9):595-600.].
