Abstract
- PURPOSE: To evaluate the visual, refractive, and contrast sensitivity outcomes, as well as the level of photic phenomena, after cataract surgery with implantation of a trifocal diffractive toric intraocular lens (IOL). METHODS: This prospective study included 56 eyes with corneal astigmatism of 1.00 diopters (D) or greater of 28 patients (age: 23 to 78 years) undergoing cataract surgery with implantation of the trifocal toric IOL AT LISA tri toric 939MP (Carl Zeiss Meditec, Jena, Germany). Monocular and binocular visual outcomes, refractive changes, contrast sensitivity, and photic phenomena perception (Halo & Glare Simulator; Eyeland-Design Network GmbH, Vreden, Germany) were evaluated at 3 months postoperatively. RESULTS: Mean 3-month postoperative monocular uncorrected distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuities were 0.13 ± 0.15, 0.08 ± 0.15, and 0.13 ± 0.18 logMAR, respectively. Binocular postoperative CDVA, DCIVA, and DCNVA values were 0.10 logMAR or better in all cases. A total of 88.2%, 88.2%, and 95.5% of eyes achieved binocular UDVA, UIVA, and UNVA values of 0.20 logMAR or better, respectively. Postoperative refractive cylinder was 0.50 D or less and 1.00 D or less in 78.6% and 98.2% of eyes, respectively. Photopic contrast sensitivity was significantly better than mesopic values for the spatial frequencies of 6 ( P = .007), 12 ( P = .005), and 18 cycles/degree ( P = .011). Mean size and intensity of halos were 50.67 ± 15.69 and 54.89 ± 17.86, respectively. Mean glare size and intensity were 39.67 ± 3.51 and 44.67 ± 15.01, respectively. CONCLUSIONS: The evaluated trifocal diffractive toric IOL provides an effective restoration of the distance, intermediate, and near vision after cataract surgery with good levels of visual quality and minimal photic phenomena.
