飞秒激光辅助与传统超声乳化术后黄斑和视盘区神经纤维层厚度及血管密度变化
Changes in nerve fiber thickness and vascular density in macula and optic disc after femtosecond laser assisted and conventional phacoemulsification
摘要
Abstract
·AIM:To observe the changes of nerve fiber thickness and vessel density in macula and optic disc following femtosecond laser-assisted and conventional phacoemulsification cataract surgery through optical coherence tomography angiography(OCTA). ·METHODS:A total of 65 cases(85 eyes)that diagnosed with age-related cataract and received surgery in Aier Eye Hospital(East of Chengdu)were included in this prospective nonrandomized controlled study.The patients were divided into two groups according to the surgery choice,with 23 cases(30 eyes)in femtosecond laser assisted group,and 42 cases(55 eyes)in traditional phacoemulsification group.OCTA was used to compare the changes in central macular thickness,thickness of nerve fiber layer in optic disc,vessel density and blood perfusion preoperatively,and at 1 d and 1 mo postoperatively. ·RESULTS:BCVA of patients in the two groups was significantly improved and IOP was significantly reduced at 1 mo postoperatively(all P＜0.01).The macular nerve fiber layer thickness of the femtosecond laser-assisted group was increased at 1 d and 1 mo postoperatively(all P＜0.05),while there was no statistical difference in the traditional phacoemulsification group before and after surgery(all P＞0.05);there were significant differences in nerve fiber layer thickness in optic disc,vessel density and blood perfusion in both macula and optic disc of the traditional phacoemulsification group(all P＜0.05),but there were no differences in the femtosecond laser assisted group(all P＞0.05).Furthermore,there were no significant differences in foveal avascular zone area in the two groups of patients(all P＞0.05). ·CONCLUSION:Femtosecond laser-assisted cataract surgery had less impact on retinal vessels.关键词
