RÉSUMÉ
@#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.
RÉSUMÉ
PURPOSE: To report two cases of toxic corneal reaction induced by infusion of distilled water into anterior chamber during cataract surgery. CASE SUMMARY: The first case was a 60-year-old female who was inadvertently infused with distilled water for 20 minutes during phacoemulsification in place of balanced salt solution (BSS). The second case was a 70-year-old male who received anterior chamber irrigation with distilled water for approximately 1 minute then and then immediately irrigated with BSS as soon as the mistake was identified. In both cases, topical 1% prednisolone acetate and 5% NaCl solution was immediately administered every hour as well as oral prednisolone at 1 mg/kg for one week after which the dose was slowly tapered. The first case completely returned to normal after 3 months, whereas the second case only requied 1 month to return to pre-surgery conditions. CONCLUSIONS: Patients who were exposed to distilled water within the anterior chamber resulted in corneal endothelial damage and corneal edema proportionate to the amount irrigated. However, The corneal edema gradually healed with treatment and eventually regained translucency without complications, completely.
