AIM:

To investigate the relationship between crystalline lens rise(CLR)measured by anterior segment-optical coherence tomography(AS-OCT)and parameters of the anterior segment. And also measure the effects of CLR on the vault after phakic posterior chamber implantable collamer lens(PPC-ICL)implantation.<p>

METHODS:

The study included 80 eyes of 40 patients who underwent PPC-ICL implantation at the Department of Ophthalmology, the Second Affiliated Hospital of Anhui Medical University, from July 2017 to July 2018, to measure the sulcus-to-sulcus(hSTS)distance of the eyes using a Compact Touch STS ultrasound biomicroscope and lens curvature(LC), Pentacam was used to measure horizontal-white-to-white(hWTW), anterior chamber depth(ACD)and the vault one year after the operation. Moreover, AS-OCT was used to measure the CLR and horizontal iridocorneal angle-to-iridocorneal angle diameter(ATA).<p>

RESULTS:

CLR was negatively correlated with ACD(<i>r</i>= -0.706, <i>P</i><0.01)and vault one year after the operation(<i>r</i>= -0.509, <i>P</i><0.01); however, it was positively correlated with LC(<i>r</i>=0.667, <i>P</i><0.01). There was no correlation between CLR and hWTW(<i>r</i>=0.123, <i>P</i>=0.275), ATA(<i>r</i>=0.208, <i>P</i>=0.065)and hSTS(<i>r</i>=0.147, <i>P</i>=0.194). One year after the operation, there was a positive correlation between the vault and ACD(<i>r</i>=0.680, <i>P</i><0.01).<p>

CONCLUSION:

CLR has obvious correlation with ACD and LC, arch height after PPC-ICL and has a specific effect on the prediction of the vault after PPC-ICL implantation.
