Abstract

Purpose: To assess the impact of inserting an ophthalmic viscoelastic device (OVD) into the dexamethasone (DEX) implant needle on pellet velocity in simulated vitrectomized eyes.

Methods: DEX implants were injected into a calibrated ex vivo test chamber filled with balanced salt solution (BSS). All DEX implants were administered by the same physician and aiming for the same button depression time. In Group 1, three DEX implant injections were performed without an OVD, while in Group 2, the OVD was safely inserted into the DEX implant needle using a 27-gauge cannula just prior to injection. The slow-motion video mode of the IPhone 14 was utilized to record the procedures and calculate time and distance measurements.

Results: Group 1 exhibited a mean velocity of 450 mm/sec for the DEX pellet in BSS, compared to 54.57 mm/sec in Group 2. Furthermore, DEX pellets in Group 1 had horizontal displacements of 24, 29, and 31 mm, while those in Group 2 had displacements of 17, 16, and 15 mm.

Conclusions: Injecting OVD into the DEX implant needle significantly decreases the velocity of the free pellet in BSS by 87.87%. This modification may help prevent potential velocity-related complications linked to DEX implantation in vitrectomized eyes.

SMARTQCA：在玻璃体切除术眼内注射地塞米松时防止速度相关并发症的简便方法。

目的：评估在地塞米松（DEX）植入针中插入眼科粘弹性装置（OVD）对模拟玻璃体切除眼球中颗粒速度的影响：方法：将地塞米松（DEX）植入针注射到装有平衡盐溶液（BSS）的校准体外试验箱中。所有 DEX 植入物均由同一位医生注射，并瞄准相同的按压时间。在第 1 组中，三次 DEX 植入注射都是在没有 OVD 的情况下进行的，而在第 2 组中，则是在注射前使用 27 号套管将 OVD 安全地插入 DEX 植入针中。使用 IPhone 14 的慢动作视频模式记录操作过程，并计算时间和距离测量值：结果：第 1 组的 DEX 粒子在 BSS 中的平均速度为 450 毫米/秒，而第 2 组为 54.57 毫米/秒。此外，第 1 组 DEX 粒子的水平位移分别为 24、29 和 31 毫米，而第 2 组的位移分别为 17、16 和 15 毫米：结论：在 DEX 植入针中注入 OVD 可将 BSS 中游离颗粒的速度显著降低 87.87%。这种改变可能有助于预防玻璃体切割眼中与 DEX 植入有关的潜在速度相关并发症。
