The visual outcome of cataract surgery in patients with a previous history of KAMRA inlay implantation is an emerging issue for which limited research exists. The purpose of this study is to describe postoperative visual outcomes in this patient population.
This is a case series with retrospective chart review. Seven patients underwent cataract surgery following KAMRA corneal inlay implantation. Visual acuity was assessed before and after cataract surgery. Keratometry was measured before and after KAMRA inlay implantation, and optical biometry was performed prior to cataract surgery.
Postoperatively, uncorrected distance visual acuity (UDVA) was 20/20 in five (71%) patients and 20/40 or better in seven (100%) patients, corrected distance visual acuity (CDVA) was 20/20 or better in six (86%) patients and 20/25 in seven (100%) patients, and uncorrected near visual acuity (UNVA) was J1 in four (57%) patients, J2 or better in six (86%) patients, and J3 or better in seven (100%) patients. There was no significant change in keratometry after KAMRA inlay implantation. Biometry calculations accurately predicted intraocular lens (IOL) power after cataract surgery. Surgeons did not report a significant change in the surgical technique of cataract surgery.
Patients who undergo cataract surgery with a previous history of KAMRA inlay implantation have good visual outcomes. Furthermore, intraocular lens (IOL) calculations accurately predict power, and there appears to be no significant change in surgical technique.
对于既往有KAMRA人工晶状体植入史的患者，白内障手术的视觉效果是一个新出现的问题，相关研究有限。本研究的目的是描述该患者群体的术后视觉效果。
这是一项回顾性病例系列研究，对病历进行回顾。7例患者在植入KAMRA角膜人工晶状体后接受了白内障手术。在白内障手术前后评估视力。在植入KAMRA人工晶状体前后测量角膜曲率，并在白内障手术前进行光学生物测量。
术后，5例（71%）患者的未矫正远视力（UDVA）为20/20，7例（100%）患者的UDVA为20/40或更好；6例（86%）患者的矫正远视力（CDVA）为20/20或更好，7例（100%）患者的CDVA为20/25；4例（57%）患者的未矫正近视力（UNVA）为J1，6例（86%）患者的UNVA为J2或更好，7例（100%）患者的UNVA为J3或更好。植入KAMRA人工晶状体后角膜曲率无显著变化。生物测量计算准确预测了白内障手术后的人工晶状体（IOL）度数。手术医生未报告白内障手术技术有显著变化。
既往有KAMRA人工晶状体植入史的患者接受白内障手术后视觉效果良好。此外，人工晶状体（IOL）计算能准确预测度数，且手术技术似乎无显著变化。
