Background And Objective:
Questions remain regarding wound stability, in particular astigmatism and leakage, in large, sutureless, clear corneal incisions. A polymethylmethacrylate (PMMA) implant, which may be more desirable than a silicone foldable in a very young patient, can be implanted through this incision.
Patients And Methods:
Twenty eyes of 19 patients underwent a 5.2-mm, temporal approach, clear corneal, sutureless phacoemulsification with intraocular lens implantation. The Langerman single hinge technique with a curvilinear groove and a triplanar, sutureless incision was used in all cases.
Results:
The average axis-corrected induced cylinder was 1.05 D of with-the-rule change. Stromal hydration was not done and only one eye required a single suture.
Conclusion:
A 5.2-mm, clear corneal incision was self-sealing, with an acceptable induced with-the-rule astigmatism.
