Abstract:
AIM: To explore the application effect of capsular tension ring(CTR)in phacoemulsification(Phaco)combined with intraocular lens(IOL)implantation for patients with high myopia, cataract and suspensory ligament relaxation.METHODS: Prospective study. A total of 80 patients(80 eyes)with high myopia, cataract and suspensory ligament relaxation who underwent Phaco combined with IOL implantation in the hospital between April 2020 and August 2021 were enrolled. According to random number table method, they were divided into CTR group(Phaco combined with CTR and IOL implantation)and control group(Phaco combined with IOL implantation), with 40 cases(40 eyes)in each group. The best corrected distance visual acuity(BCDVA), anterior capsule area, total IOL inclination and subjective visual quality before and after surgery were compared between the two groups.RESULTS: At 1, 3 and 6mo after surgery, BCDVA was improved(P<0.05), and intraocular pressure was decreased in both groups(P<0.05). The anterior capsule area in CTR group was larger than that in control group, and total IOL inclination was lower than that in control group(P<0.001). After surgery, scores of subjective visual quality in both groups were increased(P<0.05), which were higher in CTR group than control group(P<0.001). Within 6mo of follow-up, total incidence of postoperative complications in CTR group was lower than that in control group(7.5% vs. 25.0%, P<0.05).CONCLUSION: With fewer complications, the application of CTR in Phaco combined with IOL implantation is beneficial to maintain capsular morphology, reduce capsular contraction, stabilize IOL position and improve postoperative visual quality in patients with high myopia, cataract and suspensory ligament relaxation.
