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 1 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 1 year after surgery.

Changes in corneal curvatures and astigmatism after retinal surgery are well documented. Although some of these changes are mild and transient, some have reported clinically significant irregular and asymmetric corneal changes.
