ABSTRACT
AIM: To evaluate the visual quality of patients with high myopia and cataract who received micro binocular single vision implantation of Tecnis Symfony intraocular lens(IOL), hybrid implantation of Tecnis Symfony IOL and Tecnis ZMB00 multifocal IOL, and binocular implantation of AcrySof IQ Panoptix IOL.METHODS: A prospective non-randomized controlled study was conducted to select patients with high myopia and cataract who underwent phacoemulsification combined with IOL implantation in the First Affiliated Hospital of Baotou Medical College from August 2020 to March 2022. According to the different IOL implantation schemes selected by patients, they are divided into micro single vision group, hybrid group and trifocal group. The postoperative follow-up was 3mo. The observation indexes included uncorrected far(5m), middle(80, 60cm)and near(33cm)visual acuity at 3mo after operation, contrast sensitivity(CS), uncorrected defocus curve under far vision, subjective visual quality score and light interference at 1 and 3mo after operation.RESULTS: There was no significant difference among the three groups in uncorrected far(5m)and middle(60cm)visual acuity at 3mo after operation(P<0.05); Uncorrected middle(80cm)distance visual acuity in the micro single vision group was similar to that in the hybrid group, and both were better than that in the trifocal group(P<0.05); Uncorrected near(33cm)distance vision of the hybrid group showed the best, followed by the trifocal group, and the lowest was in the micro single vision group(all P<0.05). The CS of dark light plus glare(12, 18c/d)was the best in the trifocal group, followed by the hybrid group, and the lowest was in the micro single vision group(all P<0.05). The defocus curve at 3mo after operation showed a span of +1.00～-3.00D, and the visual acuity of the three groups was better than 0.3 LogMAR; In the span of -1.00～-1.25D, the visual acuity of the hybrid group and micro single vision group was better than that of the trifocal group(all P<0.05); In the span of -3.00～-3.50D, the visual acuity of the hybrid group was the best, followed by trifocal group, and the lowest was in the micro single vision group(all P<0.05). At 3mo after operation, there was no significant difference in subjective visual quality scores among the three groups(P<0.05). Light interference in the micro single vision group was higher than that of the other two groups at 1mo after operation(P<0.05), and it decreased in the three groups at 3mo after operation, with no statistical significance(P<0.05).CONCLUSION: The three IOL implantation schemes can provide excellent visual quality for patients with high myopia and cataract. The vision of the micro single vision group and the hybrid group is better in the span of -1.00～-1.25D, and the hybrid group performs the best near vision in the span of -3.00～-3.50D. Although the design of micro single vision can make up for the weakness of Symfony IOL's lack of near vision, it is still worse than the hybrid group and the trifocal group.
