Intrastromal corneal inlays are an emerging treatment for presbyopic patients. The KAMRA™ small aperture inlay was the first such inlay to receive Conformité Européenne (CE) marking in 2005. It has been shown to improve uncorrected near and intermediate visual acuity without adversely affecting uncorrected distance visual acuity. Due to the age of presbyopic patients, they may eventually develop cataracts. In two such cases, we found that cataract surgery with the KAMRA implant left in place was not technically more difficult, and that the surgical procedure could be improved by additional ocular rotations to improve visualization. Biometry readings were reliable, and it appeared that the SRK/T formula was accurate for calculation of intraocular lens power. Cataract surgery with the KAMRA implant left in situ is a viable option for patients.
角膜基质内镶嵌物是一种针对老花眼患者的新兴治疗方法。KAMRA™小孔径镶嵌物是2005年首个获得欧洲合格认证（CE）标志的此类镶嵌物。研究表明，它可提高未矫正的近视力和中视力，且不会对未矫正的远视力产生不利影响。由于老花眼患者的年龄因素，他们最终可能会患上白内障。在两例此类病例中，我们发现保留KAMRA植入物进行白内障手术在技术上并不更困难，并且通过额外的眼球转动以改善视野可使手术过程得到改进。生物测量读数可靠，而且似乎SRK/T公式在计算人工晶状体屈光度方面是准确的。保留原位KAMRA植入物进行白内障手术对患者来说是一种可行的选择。
