Surgically-induced corneal changes following macular translocation with punctate retinotomies and chorioscleral infolding (limited macular translocation)

Introduction: To report the sequential changes in corneal topography and astigmatism following limited macular translocation. Clinical Picture and Treatment: A 45-year-old-man who underwent limited macular translocation for idiopathic subfoveal choroidal neovascularisation in the right eye was evaluated by corneal topography and manifest refraction preoperatively and serially for 1 year postoperatively. Outcome: An increase in astigmatism with corneal steepening along meridians corresponding to the area of chorioscleral infolding was observed and this persisted for I year after surgery. Vector-analysed astigmatic change showed significant surgically induced astigmatism of 2.18 dioptres (D) X 52.9 degrees, 2.17 D X 57.8 degrees and 2.56 D X 59.1 degrees at 2,5 and 12 months after surgery respectively. Conclusion: Surgically induced corneal changes are evident after limited macular translocation and may remain up to I year after surgery.
