PURPOSE: To compare the incidence of corneal epithelial defects following vitrectomy surgery with Charles hand-held infusion lenses, Landers sew-on lenses, and the Oculus BIOM noncontact lens system. METHODS: We performed a retrospective chart review of 234 patients who underwent initial vitrectomy surgery by one surgeon. We determined the presence and duration of postoperative epithelial defects and identified predisposing factors. RESULTS: There were more corneal epithelial defects noted postoperatively in eyes with hand-held infusion lenses (23.8%) compared with eyes with sew-on lenses (8.6%; P = 0.010) and eyes with noncontact lenses (0%; P < 0.001). There were also more defects in sew-on versus noncontact lenses (P = 0.014). Diabetic patients had more postoperative epithelial defects with hand-held infusion lenses (32.1 %) than with sew-on lenses (8.8%; P = 0.011) or with noncontact lenses (0%; P < 0.001). The average operative time for patients with epithelial defects (169 minutes) was longer than for patients without defects (117 minutes) (P < 0.001). The risk of these defects remained significant after controlling for both length of surgery and diabetes status. CONCLUSIONS: Corneal epithelial defects were more common after vitrectomy surgery using hand-held infusion lenses than after surgery using sew-on lenses and did not occur with the noncontact lens system. In addition, reducing the operative time may independently reduce the risk of epithelial defects, regardless of lens type.
