PURPOSE: To evaluate overall patient satisfaction, spectacle independence, binocular visual acuity, rotational stability, prevalence of optical phenomena, and decentration and tilt after bilateral toric extended depth-of-focus intraocular lens (EDOF IOL) implantation targeted for micromonovision.
SETTING: Department of Ophthalmology, Hanusch Hospital, Vienna, Austria.
DESIGN: Prospective case series.
METHODS: The study included 52 eyes of 26 patients with regular corneal astigmatism from 0.75 to 2.60 diopters (D) that were implanted bilaterally with a toric EDOF IOL targeted for micromonovision. Postoperative visual acuity, astigmatism reduction, rotation, tilt, decentration, spectacle independence, patient satisfaction, and photic phenomena were assessed.
RESULTS: For the 52 eyes studied, binocular means expressed in logarithm of the minimum angle resolution for postoperative corrected distance, uncorrected distance, uncorrected intermediate, and uncorrected near visual acuities were -0.10 (±0.12), -0.01 (±0.13), 0.01 (±0.14), and 0.13 (±0.14), respectively. Mean refractive astigmatism reduction was 1.31 ± 0.67 D resulting in a mean refractive cylinder of 0.47 ± 0.46 D at the 3-month visit. Mean postoperative rotation was 3.5 ± 3.5 degrees, at the 3-month time point. Most prevalent dysphotopsia were halos, starburst, and glare affecting 6 (23%), 6 (23%), and 5 (19%) of 26 patients, respectively; 20 (77%) of 26 patients reported spectacle independence, with 19 (95%), 19 (95%), and 14 (70%) of 20 patients questioned being satisfied with distance, intermediate, and near vision, respectively.
CONCLUSIONS: Toric EDOF IOL implantation targeted for micromonovision resulted in reliable reduction of preoperative astigmatism with a high degree of postoperative rotational predictability and centration, enabling functional distance, intermediate, and near vision, which manifested itself in high patient satisfaction.
