PURPOSE: : To assess the efficacy of image-guided limbal relaxing incisions (LRIs) in enhancing outcomes of cataract surgery with trifocal intraocular lenses (IOLs) implantation.
METHODS: This prospective cohort study included consecutive cataract patients with predicted postoperative corneal astigmatism of 0.5-1.0 D and intended for cataract surgery with trifocal IOL implantation. The enrolled subjects were randomized into the non-LRI group, manual-marked LRI group and image-guided LRI group. Correction effect of corneal astigmatism, as well as visual outcomes at 3 months after surgery were compared among the three groups.
RESULTS: Finally, 30 eyes of 30 patients in every group were included. The image-guided LRI group showed more corneal astigmatism correction (0.81 ± 0.32 D vs. 0.17 ± 0.22 D vs. 0.48 ± 0.37 D, p < .001) and less refractive postoperative cylinder (0.33 ± 0.29 D vs. 0.90 ± 0.25 D vs. 0.65 ± 0.31 D, p < .001) than the non-LRI group and manual-marked LRI group. The uncorrected near visual acuity and uncorrected intermediate visual acuity were significantly better in the image-guided LRI group and manual-marked LRI group than the non-LRI group (all p < .05). The image-guided LRI group also displayed significantly better ocular modulation transfer functions than the other two groups (all p < .05).
CONCLUSION: LRIs, especially image-guided LRIs, can effectively reduce corneal astigmatism and improve both near and intermediate vision, as well as visual quality of patients undergoing trifocal IOLs implantation.
