PURPOSE To compare the safety of the minimum ophthalmic viscosurgical device (OVD) technique with the standard procedure in phakic Visian Implantable Collamer Lens (ICL) (STAAR Surgical AG, Nidau, Switzerland) implantation. METHODS This retrospective cohort study evaluated a total of 147 eyes of 74 patients who underwent ICL implantation with the minimum OVD technique (minimum OVD group) and 154 eyes of 77 patients with the standard procedure (standard OVD group). Intraoperative and postoperative complications were recorded. Preoperative and postoperative visual acuity, intraocular pressure (IOP), aqueous depth (AQD), and central corneal endothelial cell density (ECD) were collected and analyzed over the 12-month follow-up. Lens vault and occurrence of paracentesis after surgery were also recorded. RESULTS No intraocular complications were observed. No difference was found in visual outcomes, lens vault, and AQD at all time points between the two groups (P > .05). The minimum OVD group had significantly lower IOP than the standard OVD group at 2 hours (17.04 ± 4.21 vs 19.40 ± 6.78 mm Hg, P < .001) and 3 hours (15.12 ± 3.38 vs 17.15 ± 5.09 mm Hg, P < .001) postoperatively. The IOP gradually returned to the preoperative level after 24 hours postoperatively. The occurrence rate of paracentesis was significantly less in the minimum OVD group compared with the standard group (0.68% [1 of 147] vs 3.2% [5 of 154], P < .001). ECD was not significantly different between groups at all time points (P > .05). CONCLUSIONS The minimum OVD technique could achieve visual and structural outcomes comparable to the standard procedure without additional damage to the corneal endothelial cells, while reducing the IOP fluctuations after surgery.

植入式角膜接触镜的最小眼科粘膜外科手术技术的安全性。

目的比较有晶体Visian可植入式散光镜（ICL）（瑞士瑞士尼道的STAAR Surgical AG）植入术中最小眼内镜手术器械（OVD）技术与标准手术的安全性。方法这项回顾性队列研究评估了74例采用最小OVD技术（最小OVD组）进行ICL植入的患者的147眼，以及77例采用标准手术（标准OVD组）的患者的154眼。记录术中和术后并发症。在12个月的随访中，收集了术前和术后的视力，眼内压（IOP），房水深度（AQD）和中央角膜内皮细胞密度（ECD）。还记录了晶状体穹顶和手术后穿刺的发生情况。结果未观察到眼内并发症。两组在所有时间点的视觉结果，晶状体拱顶和AQD均无差异（P> 0.05）。最小OVD组在2小时（17.04±4.21 vs 19.40±6.78 mm Hg，P <.001）和3小时（15.12±3.38 vs 17.15±5.09 mm Hg，P <.001）时的IOP明显低于标准OVD组。 ）。术后24小时，眼压逐渐回到术前水平。最小OVD组的腹腔穿刺发生率明显低于标准组（0.68％[147分之一]与3.2％[154分之5]，P <.001）。各时间点各组之间的ECD差异均无统计学意义（P> 0.05）。结论最低限度的OVD技术可达到与标准手术相当的视觉和结构效果，而又不损害角膜内皮细胞，同时减少手术后的IOP波动。[J Refract Surg。2020; 36（1）：42-48。]。
