Abstract EN
Purpose.
To compare the surgically induced astigmatism from clear corneal and square posterior limbal incisions at the time of cataract surgery.
Methods.
Surgically induced astigmatism was calculated for a set of eyes after cataract surgery using a temporal 2.2 mm square posterior limbal incision.
Results were compared to similar available data from surgeons using clear corneal incisions of similar size.
Results.
Preoperative corneal astigmatism averaged 1.0 D and was not significantly different between the incision types.
Surgically induced astigmatism with the 2.2 mm posterior limbal incision averaged 0.25±0.14 D, significantly lower in magnitude than the aggregate surgically induced astigmatism produced by the 2.2 mm clear corneal incision (0.68±0.49 D).
Conclusion.
The 2.2 mm square posterior limbal incision induced significantly less, and significantly less variable, surgically induced astigmatism relative to a similar-sized clear corneal incision.
This is likely to improve refractive outcomes, particularly important with regard to premium intraocular lenses.
