Intraocular Surgery and Lenses

Purpose: To evaluate the visual outcome and optical quality in eyes with diffractive multifocal intraocular lens (DMIOL) implantation after myopic refractive surgery.Methods: Nineteen eyes (15 patients) were implanted with AcriSof ReSTOR ® SN6AD1, the aspheric DMIOL after myopic refractive surgery (laser-assisted in situ keratomileusis [LASIK] 14 eyes, photorefractive keratectomy [PRK] 4 eyes, laser-assisted subepithelial keratomileusis [LASEK] 1 eye).Preoperative and postoperative visual acuities and manifest refraction were measured.Preoperative corneal higher-order aberrations (HOAs) were measured using Hartmann-Shack (H-S) aberrometer in dilated pupils, and optical qualities were measured 1 month postoperatively using H-S aberrometer and a double-pass system under mesopic conditions.Patient satisfaction was investigated using a questionnaire at 2 months postoperatively.Results: Uncorrected distant and near visual acuities at postoperative 2 months were 0.11 ± 0.19, and 0.19 ± 0.12 (log MAR), respectively.Postoperative spherical equivalent (SE) of 16 eyes (84.2%) was within ±0.50 diopters (D) and all eyes were within ±1.00 D from emmetropia.Preoperative corneal and postoperative ocular spherical aberrations in a 4.0 mm pupil diameter were 0.08 ± 0.08 and 0.07 ± 0.07 (μm), respectively.Objective scatter index was 3.42 ± 1.71 and modulation transfer function (MTF) cut-off value was 21.03 ± 12.37 cpd.General satisfaction score was 3.52 ± 0.96 points out of 5, and 8 patients (11 eyes) were not satisfied with DMIOL implantation.Conclusions: After DMIOL implantation in the eyes with previous myopic refractive surgery, postoperative SE was close to the target D, but optical qualities and patient satisfaction were poor.
