| description | AIM: To observe the clinical effect of posterior chamber phakic refractive lens(PC-PRL)implantation in the treatment of ultra-high myopia.METHODS: Retrospective case study. A total of 36 patients(67 eyes)with ultra-high myopia who underwent PC-PRL implantation in our hospital from January 2021 to January 2022 were selected. They were and divided into two groups according to the preoperative spherical equivalent, with 16 cases(30 eyes)in spherical equivalent ≤-18.00D group and 20 cases(37 eyes)in spherical equivalent >-18.00D group. The preoperative and postoperative visual acuity, intraocular pressure(IOP), corneal endothelial cell density(ECD), central anterior chamber depth(ACD)and postoperative vault and complications were compared and analyzed.RESULTS: The uncorrected visual acuity(UCVA)at 3mo after operation of the two groups reached or exceeded the preoperative best corrected visual acuity(BCVA; all P<0.05), and the spherical equivalent >-18.00D group had a greater visual acuity improvement(P<0.01). There were significant differences in IOP and corneal ECD between the two groups at 1d after operation and before operation(all P<0.05); The vault at different time points decreased after operation, but it was within the normal range; The ACD at 3mo after operation was lower than that before operation(all P<0.01). There was no difference in intraocular pressure, ECD, ACD and postoperative vault between the two groups(P>0.05). No serious postoperative complications occurred in both groups.CONCLUSION: The PC-PRL implantation had improved early visual acuity and stable refractive state, which was safe and reliable, and there were no serious complications in the treatment of patients with ultra-high myopia. |
