[Asymmetric corneal tunnel incision for routine phacoemulsification and lens implantation]
1Universitäts-Augenklinik, Brüssel.
Abstract
Unlabelled:
This study was designed to investigate whether it is possible to improve wound stability and reduce induced astigmatism of a linear corneal tunnel incision for the implantation of foldable intraocular lenses by radializing wound components.
Materials And Methods:
A 4.1-mm linear and a 2.5 x 2.5-mm L-shaped corneal tunnel incision were compared in 60 and 59 patients, respectively.
Results:
Complications and induced astigmatism (vector analysis) were significantly less in the L-shaped incision group than in the linear incision group (0.62 +/- 0.53 D vs. 0.84 +/- 0.75 D after 3 months).
Conclusion:
An L-shaped incision seems to be superior to the conventional linear type.
