Abstract：Objective: To study the visual quality after femtosecond laser-assisted cataract surgery (FLACS) combined with TECNIS Symfony intraocular lens (IOL) implantation. Methods: A total of 148 patients (148 eyes) with cataract who underwent FLACS combined with IOL implantation in the hospital between August 2018 and October 2020 were selected and divided into study group and control group by simple random grouping method with 74 patients in each group. Patients in the study group were treated with TECNIS Symfony IOL, while patients in the control group were treated with traditional spherical monofocal IOL. Changes in visual acuity, contrast sensitivity (CS), wavefront aberration, corneal refractive power and astigmatism before and after treatment were compared between the two groups, and visual quality after surgery was evaluated. Results: There was no significant difference in uncorrected distant visual acuity, corrected visual acuity, CS from different angles, total low order aberrations and satisfaction with distant vision between the two groups (P>0.05). However, the uncorrected middle and near visual acuity, satisfaction with near vision and middle vision, spectacles-independent rate while reading and VF-14 score of the study group were significantly higher than those of the control group. The overall aberrations and overall high-order aberrations were significantly lower than those of the control group (P<0.05). After surgery, overall refractive power of the two groups was significantly reduced, and the overall astigmatism was significantly increased (P<0.05), but the comparison between the two groups before and after the operation showed no statistical significance (P>0.05). Conclusion: FLACS combined with TECNIS Symfony IOL implantation can better meet the vision needs of patients with cataract and provide them with high visual quality.
