摘要
目的:观察有晶状体眼后房屈光晶状体(PC-PRL)植入术治疗超高度近视的临床疗效。方法:回顾性病例研究。选取2021-01/2022-01于我院行PC-PRL植入术治疗的超高度近视患者36例67眼,按术前球镜度数分成两组:球镜≤-18.00D者16例30眼和球镜>-18.00D者20例37眼。比较两组患者手术前后视力、眼压、角膜内皮细胞密度(ECD)、中央前房深度(ACD)以及术后拱高、并发症的情况。结果:两组患者术后3mo UCVA均达到或超过术前BCVA(均P<0.05),且球镜>-18.00D组的视力提高幅度更大(P<0.01);两组患者术后1d眼压、角膜内皮细胞密度与术前比较均有差异(均P<0.05);术后不同时间点拱高均呈下降趋势,但均在正常范围内;术后3mo ACD均低于术前(均P<0.01)。两组间手术前后眼压、ECD、ACD及术后拱高比较均无差异(P>0.05)。两组患者术后均未发生严重并发症。结论:PC-PRL植入术治疗超高度近视患者早期视力得到良好改善、屈光状态稳定、安全可靠、无严重并发症。
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.
