Abstract Purpose The aim of this study was to evaluate whether the simulated tissue models may be used in place of animal-based model for corneal laceration repair for surgical skills acquisition. Design Prospective randomized controlled trial. Participants Seventy-nine military and civilian 2nd- and 3rd-year ophthalmology residents and 16 staff ophthalmologists participating in the Tri-Service Ocular Trauma Skills Laboratory at the Uniformed Services University (Bethesda, MD). Methods Resident ophthalmologists underwent preliminary evaluation of their ability to close a 5-mm linear, full-thickness corneal laceration involving the visual axis. They then were randomized to undergo 90 to 120 minutes of either simulator-based (SIM) or swine cadaveric-tissue-based (CADAVER) corneal laceration repair. The same evaluation was performed post training. On a more limited basis, the study was repeated for attending ophthalmologists to act as a pilot for future analysis and test efficacy for “refresher” training. Main Outcome Measures Successful wound closure with secondary outcomes of suture length, tension, depth, and orientation, as graded by attending ophthalmologists. Results No significant difference in CADAVER versus SIM groups in the primary outcome of watertight wound closure of the corneal laceration. CADAVER group performed better than SIM group for certain metrics (suture depth, p = 0.009; length, p = 0.003; and tension, p = 0.043) that are associated with poor wound closure and increased amount of induced corneal astigmatism. For attending ophthalmologists, six of the eight in each group (SIM and CADAVER) retained or improved their skills. Conclusions For resident ophthalmologists, SIM training is sufficient for achieving the primary outcome of watertight wound closure. However, CADAVER training is superior for wound metrics for the ideal closure. For attending ophthalmologists, SIM training may be useful for retention of skills.

The objective of this case report was to present the development of implantation cyst following the perforating corneal injury, the problems related to the treatment, including total surgical excision of the cyst, the secondary cataract extraction, iridoplasty and the artificial intraocular lens reposition. A patient first presented with perforating corneal injury inflicted by a piece of wood, with the iris prolapse. Primary wound management, reposition of prolapsed iris and corneal sutures were performed four days after the injury. Eight months later, the patient was rehospitalized due to an implantation iris cyst and traumatic cataract. The cyst was excised, the extracapsular cataract extraction was done and the anterior chamber lens was implanted. Postoperative visual acuity was normal. Three years later, the patient presented for a follow-up examination, with the cyst filled up again, occupying two thirds of the anterior chamber. This time, the cyst was completely excised, all fibrous remnants of the secondary cataract were removed, and the iridoplasty was necessary due to large iris coloboma. Reposition of the anterior chamber lens was carried out. Histological examination revealed an implantation iris cyst covered by multilayered squamous epithelium. Normal visual acuity was achieved. The patient has been followed-up for six months uneventfully. Management of perforating corneal wound with iris prolapse may lead to development of an implantation iris cyst. Puncture of the cyst as well as incomplete excision will not solve the problem. Complete surgical removal of the iris cyst is the treatment of choice.

Corneal Laceration

Background: Nd:YAG capsulotomy is the treatment of choice for posterior capsular opacification after cataract surgery. We report a case of corneal perforation following Nd:YAG capsulotomy in a patient with systemic scleroderma. Case Presentation: A 69-year-old woman presented with acute onset of blurred vision 2 weeks following Nd:YAG laser capsulotomy for posterior subcapsular opacification. On examination, her best-corrected visual acuity was 1/120, and bio-microscopy revealed a central full-thickness corneal laceration. Conservative treatment consisted of topical ocular antibiotics, cycloplegics, hypotensive drops and a soft therapeutic contact lens. Her final visual acuity improved to 6/18 with resolution of the corneal laceration. Conclusion: The possibility of corneal perforation after Nd-YAG capsulotomy in patients with systemic scleroderma and connective tissue disease should be borne in mind when treating such patients.
