Title: Compressive C-shaped lamellar keratoplasty: a surgical alternative for the management of severe astigmatism from peripheral corneal degeneration. Author: Cheng CL, Theng JT, Tan DT. Journal: Ophthalmology; 2005 Mar; 112(3):425-30. PubMed ID: 15745769. Abstract: OBJECTIVE: To describe a compressive lamellar surgical technique for treating severe astigmatism in peripheral corneal ectasia. DESIGN: Retrospective, noncomparative, interventional case series. PARTICIPANTS: Four eyes of 3 patients with either pellucid or Terrien's marginal corneal degeneration were included in this series. METHODS: C-shaped lamellar keratoplasty using multiple trephines of different sizes, with deliberate undersizing of the donor graft for a controlled compressive effect, was performed on these patients. MAIN OUTCOME MEASURES: Visual acuity outcome and refraction were measured at different intervals at up to 40 months of follow-up. RESULTS: All eyes achieved Snellen visual acuity of 20/40 or better and stable astigmatism ranging from 0 to -2.75 diopter cylinder within 6 months, with no recurrence of corneal thinning or peripheral corneal vascularization. CONCLUSIONS: Compressive C-shaped lamellar keratoplasty is able to reduce severe corneal astigmatism in peripheral corneal ectasia and can result in good visual and refractive outcomes with early visual rehabilitation.[Abstract] [Full Text] [Related] [New Search]
