Predicting Postoperative Intraocular Lens Dislocation in Cataract Surgery via Deep Learning

open access: yesIEEE Access
A critical yet unpredictable complication following cataract surgery is intraocular lens dislocation. Postoperative stability is imperative, as even a tiny decentration of multifocal lenses or inadequate alignment of the torus in toric lenses due to ...
