Application of 23-G vitrectomy via cornea approach in ocular trauma

Objective To investigate the effect of first-stage 23-G vitrectomy via cornea approach in the treatment of ocular trauma.Methods This retrospective study involved a total of 26 eyes from 26 patients who suffered from complicated ocular trauma.Lensectomy and anterior vitrectomy via cornea approach were performed:two incisions were made using a 23-G stab knife in transparent cornea near limbus.Trocars were inserted:one connected to the infusion tube and the other made the vitreous cutter enter anterior chamber.Results No complications occured during the operations.The postoperative best corrected visual acuity was better than 0.5 in 3 eyes(11.54％),from 0.1 to 0.4 in 8 eyes(30.72％),from 0.02 to 0.08 in 12 eyes(46.15％),less than CF in 3 eyes(11.54％).The mean IOP at 3 days and 1 week after surgery was (13.26 ±4.83) mmHg and (14.65 ±3.91) mmHg respectively.The intraocular lens (IOL) were implanted in 18 eyes later.9 eyes had retinal reattachment after timely vitreoretinal surgery.Conclusion Firststage 23-G vitrectomy via cornea approach is very effective for the complicated ocular trauma.
