To provide an initial evaluation of clinical and spectacle use one month after refractive lens exchange and implantation of a new extended depth of focus (EDoF) intraocular lens (IOL).
The first patients who underwent refractive lens exchange with implantation of a new EDoF IOL (AT LARA, ZEISS MEDITEC) and achieved one month postoperative followup were retrospectively analyzed. When the intention was to perform the procedure on both eyes, there was a one day interval between eyes. Refractive and acuity clinical outcomes as well as the postoperative use of spectacles to correct distant and near vision were assessed. Near vision was measured using a reading chart with logarithmically sized letters at 40cm.
There were 12 males and 10 females (42 eyes of 22 patients) with a mean age of 57.6 ± 7.7 years (47 to 72) who underwent uncomplicated phacoemulsification with implantation of the EDoF IOL. A reduction in mean manifest refraction spherical equivalent was noted from a preop mean of +1.61 ± 0.87D (-0.625 to +3.375D) to one month postop of -0.13 ± 0.45D (-1.75 to +0.875). There was a mean gain of 5 and 6 lines in uncorrected distant (UCDVA) and near vision, respectively, after surgery compared to preoperative unaided vision, and 61.5% and 95.2% of eyes achieved UCDVA of 20/20 and 20/40, respectively. Twenty one patients (95.5%) did not use spectacles for either distant or near activities postoperative. One patient (4.5%) required distant and near spectacles for 25% of the time during the day.
In this initial evaluation of a new EDoF IOL, unaided distant and near vision was improved by a mean of 5 and 6 lines, respectively, without complications. Only one patient required occasional use of glasses to correct distant and near vision.
