Viscoat viscoelastic combined with soft corneal contact lens for central corneal perforation / 眼科新进展

ABSTRACT

Objective To investigate the clinical effects of the Viscoat viscoelastic combined with soft corneal contact lens for central corneal perforation.Methods Six cases were collected and treated with corneal local debridement of which diameter were less than 2.0 mm.Six cases received Viscoat viscoelastic injection into their anterior chamber.And then soft corneal contact lens were worn.The curative effect indicators such as patients' symptom,visual acuity,slit lamp examination,intraocular pressure,confocal microscope and corneal endothelial cell counts were recorded in the follow-up periods.Results All the cases were healed with the recovery time of 1 month to 2 months;After treatment,the best corrected visual acuity of patients were increased to 0.6-0.8 and average corneal endothelial cell count was (3415.5 ±279.5)mm-2.No obvious scar was left in the cornea and no serious complicatious occurred during treatment.Conclusion For traumatic corneal central perforation with diameter is 2.0 mm or less can be treated with Viscoat viscoelastic combined with soft corneal contact lens.This therapy is worthy of popularize since it's satisfied prognosis and less economic burden.
