Purpose:
To evaluate the course of astigmatic evolution and complications after clear corneal incisions using an intrastromal corneal suture.
Setting:
Instituto Oftalmologico de Alicante, University of Alicante, Spain.
Methods:
Eighty eyes of 62 patients had endocapsular phacoemulsification. A foldable intraocular lens was implanted through a 4.0 mm clear corneal incision. A 10-0 nylon intrastromal corneal suture was used in all eyes. Change sin corneal astigmatism were calculated by vector analysis; follow-up was 6 months. Early and late suture-related complications were also evaluated.
Results:
Mean induced cylinder was 1.25 diopters (D) +/- 1.24 (SD) with the wound 1 day postoperatively and 0.19 +/- 0.81 D against the wound at 6 months. There were no incision- or suture-related complications postoperatively.
Conclusion:
Use of the intrastromal corneal suture led to astigmatically neutral closure of multiplanar corneal incisions.
