Combining Small Aperture Approach and Toric Correction for Irregular Astigmatism Management

The authors investigate whether a hybrid intraocular lens (IOL) design that combines small-aperture and toric elements can effectively manage irregular astigmatism in cataract surgery, which is challenging due to complex geometries and higher-order aberrations. Their experimental study reveals that this combined IOL significantly improves optical performance compared to traditional toric or small-aperture IOLs alone, suggesting that such a hybrid approach could enhance visual outcomes in patients with complex corneal profiles.
