- Abstract: Objective To investigate the stability of pouch in patients with high myopia cataract after phacoemulsification cataract extraction combined with capsular tension ring(CTR)implantation.Methods A total of 80 patients with high myopia complicated with cataract(80 eyes)were included and randomly divided into the experimental group and the control group.The experimental group received phacoemulsification cataract extraction combined with CTR implantation,while the control group was not combined with CTR implantation,and the other interventions were completely consistent.The naked eye visual acuity(UCVA),best corrected distant visual acuity(BCVA),corneal biomechanics,contrast sensitivity,intraocular lens inclination and anterior capsular opening area were compared between the two groups at 1,3 and 6 months after surgery.The incidence of late cataract(PCO)was measured 6 months after surgery.Results UCVA and BCVA were improved at 1,3 and 6 months after operation.There were no significant differences in postoperative corneal biomechanical parameters ARTh and SP-A between the two groups of patients(P＞0.05).The Corvis biomechanical index(CBI)of the experimental group was significantly higher 3 months after surgery than that of the control group(P＜0.05),and there were no significant differences at other time points between the 2 groups.There was no significant difference in contrast sensitivity at each time point after surgery between the experimental group and the control group(P＞0.05).At 3 and 6 months after operation,the anterior capsule opening area was increased in the experimental group,and IOL inclination angle was decreased compared with the control group(P＜0.05).At 6 months after operation,no PCO occurred in 38 eyes and PCO grade Ⅰ in 2 eyes.No PCO occurred in 35 eyes in the control group,3 eyes in grade Ⅰ,2 eyes in grade Ⅱ and 2 eyes in grade Ⅲ.Conclusion Phacoemulsification cataract extraction combined with CTR implantation has higher stability,long-term clinical effect and visual quality in patients with high myopia cataract,and is worthy of clinical application.
