AIM: To explore the application of improved skills in central hole ICL V4c implantation and its clinical efficacy. <p>METHODS: This study included 141 eyes of 72 patients with myopia from September 2015 to August 2016. An implantable contact lens with a central hole(ICL V4c)was inserted by improved surgical skills including single 2.8mm clear corneal incision, no anterior chamber viscoelastics before ICL implantation. The intraocular pressure(IOP)was measured at the early stage within 6h after operation. The visual acuity, diopter, intraocular pressure and corneal endothelial cell density were observed after operation and follow up 2a. <p>RESULTS: ICL V4c was implanted successfully in all patients by this improved skills and fine clinical results were achieved. Elevated IOP is possible at early stage post-operation, especially within 2h after operation. 95.7% had normal IOP 6h after operation. The postoperative IOP was stable within 2a follow-up period. The cumulative corneal endothelial loss rates of 6mo, 1a and 2a were 4.70%, 7.59% and 9.63% respectively. There was no complications such as subcapsular cataract during the 2a follow-up period.<p>CONCLUSION: The improved skills used in our study is safe and feasible.
