Analysis of the influencing factors of vault after the implantation of posterior chamber-phakic refractive lens for patients with super high myopia

AIM: To investigate the influencing factors of vault after the posterior chamber phakic refractive lens(PC-PRL)implantation for patients with super high myopia.METHODS: Retrospective case study. A total of 40 patients with super high myopia(77 eyes)who underwent PC-PRL implantation in the Haixiang E...

description AIM: To investigate the influencing factors of vault after the posterior chamber phakic refractive lens(PC-PRL)implantation for patients with super high myopia.METHODS: Retrospective case study. A total of 40 patients with super high myopia(77 eyes)who underwent PC-PRL implantation in the Haixiang Eye Hospital from January 2019 to January 2021 were selected. They were followed up for at least 2a, postoperative anterior segment parameters, such as the uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), central anterior chamber depth(ACD), anterior chamber volume(ACV), anterior chamber angle(ACA), lens thickness and vault were evaluated, and then the influencing factors of postoperative vault were analyzed.RESULTS: The UCVA and BCVA of the patients significantly improved after PC-PRL implantation(P<0.001). Average safety index(postoperative BCVA/preoperative BCVA)was 1.36±0.32, and average effective index(postoperative UCVA/preoperative BCVA)was 1.23±0.31 in 2a after surgery. The vault in 2a after surgery was correlated with preoperative ACD, ACV, ACA and lens thickness, and the preoperative ACV and lens thickness had significant impact on vault in 2a after surgery.CONCLUSIONS: The PC-PRL implantation is safe and effective in super high myopia, and it can significantly improve visual acuity. Furthermore, preoperative ACV and lens thickness are important influencing factors of postoperative vault.
