Phacoemulsification combined with CTR implantation in the treatment of high myopia with cataract / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To explore the efficacy of phacoemulsification combined with capsular tension ring(CTR)implantation in the treatment of patients with high myopia complicated with cataract, and to analyze its safety. <p>METHODS: A retrospective analysis was performed on the clinical data of 186 patients(186 eyes)with high myopia and cataract who underwent phacoemulsification+ intraocular lens(IOL)implantation treatment in our hospital. Among them, 98 cases(98 eyes)were combined with CTR implantation(combined group)and 88 cases(88 eyes)were not combined with CTR implantation(control group). The best corrected visual acuity(BCVA, LogMAR), visual quality \〖root mean square value(RMS)of higher-order aberration(HOA)\〗 and corneal endothelial cell density were recorded in the two groups before surgery and at 1, 3 and 6mo after surgery, and the area of anterior capsular orifice and inclination angle of IOL were evaluated at 1, 3 and 6mo after surgery, and the occurrence of complications such as postoperative anterior capsule opacification, posterior capsule opacification and capsular contraction syndrome were compared between the two groups.<p>RESULTS: There were interaction effects in the BCVA between the two groups(<i>P</i><0.05). The BCVA of the two groups after surgery was decreased compared with that before surgery(<i>P</i><0.05), and the BCVA of combined group after surgery was lower than that of control group(<i>P</i><0.05). There were interaction effects in the total HOA RMS(<i>P</i><0.05), and the total HOA RMS of the two groups after surgery was increased compared with that before surgery(<i>P</i><0.05), and the total HOA RMS after surgery in combined group was lower than that in control group(<i>P</i><0.05). There were interaction effects in the anterior capsular orifice area after surgery between the two groups(<i>P</i><0.05), and the area in the two groups was decreased with the prolongation of postoperative time(<i>P</i><0.05), and the area in combined group at 3 and 6mo after surgery was higher than that in control group(<i>P</i><0.05). The IOL inclination angle of the two groups had interaction effects between the two groups(<i>P</i><0.05), and the angle of the two groups was increased with the prolongation of postoperative time(<i>P</i><0.05), and the angle of combined group at 3 and 6mo after surgery was lower than that of control group(<i>P</i><0.05). The corneal endothelial cell density in the two groups after surgery was lower than that before surgery(<i>P</i><0.05), but there was no interaction effect(<i>P</i> >0.05).<p>CONCLUSION: Phacoemulsification+ IOL implantation + CTR implantation can improve the visual function of patients with high myopia complicated with cataract, with few postoperative complications and good efficacy and safety.
