Asymmetric L-shaped corneal no-stitch tunnel incisions for cataract surgery.
OBJECTIVE
To assess whether a unilateral asymmetric radial enlargement of a corneal tunnel incision for implantation of foldable intraocular lenses yields advantages over conventional linear enlargements.


METHODS
Department of Ophthalmology, University of Brussels, VUB, Belgium.


METHODS
Asymmetric corneal tunnel incisions with an L-shaped entrance and a concave exit were compared with equivalent conventional linear incisions in patients and in postmortem eyes.


RESULTS
The asymmetric no-stitch L-designs scored consistently better than the symmetric linear designs in induced astigmatism, postoperative astigmatic shift, complications, and pressure resistance.


CONCLUSIONS
An asymmetric corneal L-incision is superior to a conventional symmetric linear incision.
