微单视设计双眼连续视程人工晶体植入术后视觉质量分析

Visual quality study following bilateral implantation of extended range of vision(ERV)tecnis symfony intraocular lens(IOL)with micromonovision design

目的 评估微单视设计双眼植入连续视程人工晶体后患者视觉质量及满意度。方法 本研究为前瞻性研究,招募2021年8月至12月在四川省人民医院眼科接受手术的40位患者。术前测主视眼,术后第1天、1周、1个月和3个月进行随访。指标:双眼裸眼视力;离焦曲线;OQAS视觉质量;满意度问卷。结果 患者术后视力提高,全程视力表现平稳;客观散射指数、调制传递函数截止频率、斯特列尔比值、模拟对比度视力的差异无统计学意义(P<0.05为有统计学意义);个别患者有光晕、眩光不适,但总体脱镜率高,满意度高。结论 本设计中患者满意度高,可完善围手术期评估与治疗后进一步推广。

Objective To evaluate the patient visual quality and satisfaction following bilateral implantation of EDOF(Extended depth of focus lens)lens with Micromonovision design.Methods This prospective study recruited 40 patients who received binocular cataract phacoemulsification surgery from Si Chuan Provincial People’s Hospital from August to December 2021.Tests on all 40 patients for both dominant eyes done prior to surgery,and postoperative follow-up visits for the aforesaid patients were exercised 1 day,1 week,1 month,and 3 months after surgery.The criteria of the follow-up were focused on uncorrected visual quality,defocus curve,OQAS visual quality and patient satisfaction.Results Significant improvement in the patient visual quality has been shown in this study,and patients were observed with stable performance for uncorrected far,intermediate and near vision.There was no statistical significance in the difference in objective scatter index(OSI),the modulation transfer function cut-off frequency(MTF cut-off),Steel ratio(SR)and simulated contrast visual acuity.(P<0.05 was considered statistically significant)Though light halo and glare has been observed on some individual patient,however,a high spectacle independence rate and high satisfaction were reported among these recruited.Conclusion A generally high satisfaction has been reported in the patients after cataract phacoemulsification surgery and bilateral implantation of EDOF lens with micromonovision design.The foregoing design is recommended for application after consummation in the perioperative assessment and treatment.
