To evaluate the outcome of surface deposits that occurred during implantation of hydrophylic acrylic intraocular lenses (IOLs) through a hexagonal cartridge.
Surface deposits were observed on the posterior surface of the ACR6D SE IOLs that were injected through a hexagonal cartridge filled with sodium hyaluronate 1%. All the patients were examined 1 day, 1 week, 1 month, 6 months and 1 year postoperatively. The location of the deposits was recorded and photographed. The patients were questioned about blurred vision, glare or halos.
Linear or curly deposits were detected on the posterior surface of the IOL in six patients. In four patients, the deposits were peripheral and were observed 1 week postoperatively. In two patients, the deposits were noticed immediately after implantation. In one eye, they were misinterpreted as a crack in the IOL's optic and were left in the eye. In the second patient the deposits were removed immediately after implantation with forceps. The deposits that were left after implantation (five eyes) did not resolve during 1 year of follow-up. None of the eyes developed abnormal inflammatory reaction. In three eyes the best-corrected visual acuity (BCVA) was 6/6. In the other three eyes the BCVA was 6/12. None of the patients experienced any visual disturbance.
Implantation of the ACR6D SE IOL through a hexagonal cartridge can lead to the formation of deposits on the posterior surface of the lens. The deposits do not resolve and may resemble a crack in the IOL. The deposits left on the IOL had no clinical relevance in our patients.
评估通过六边形药筒植入亲水性丙烯酸人工晶状体（IOL）期间发生的表面沉积物的结果。
在通过装有1%透明质酸钠的六边形药筒注射的ACR6D SE IOL的后表面观察到表面沉积物。所有患者在术后1天、1周、1个月、6个月和1年进行检查。记录沉积物的位置并拍照。询问患者有关视力模糊、眩光或光晕的情况。
在6例患者的IOL后表面检测到线性或卷曲状沉积物。4例患者的沉积物位于周边，在术后1周观察到。2例患者在植入后立即注意到沉积物。在一只眼中，它们被误判为IOL光学部的裂缝并留在眼内。在第二例患者中，沉积物在植入后立即用镊子取出。植入后留下的沉积物（5只眼）在1年的随访期间未消退。所有眼睛均未出现异常炎症反应。3只眼的最佳矫正视力（BCVA）为6/6。在其他3只眼中，BCVA为6/12。所有患者均未经历任何视觉干扰。
通过六边形药筒植入ACR6D SE IOL可导致晶状体后表面形成沉积物。这些沉积物不会消退，可能类似于IOL中的裂缝。留在IOL上的沉积物在我们的患者中没有临床意义。
