TORIC INTRAOCULAR LENSES: HISTORICAL OVERVIEW, PATIENT SELECTION,IOL CALCULATION, SURGICAL TECHNIQUES, CLINICAL OUTCOMES, AND COMPLICATIONS
Keywords:
Toric intraocular lens, Multifocal, Phacoemulsification, Distance visual acuity, Refractive astigmatismAbstract
An overview of currently disponible toric intraocular lenses IOLs and multifocal toric IOLs is presented. Appropriate patient selection criteria, IOL calculation issues, and surgical techniques for IOL implantation are negotiated. Clinical outcomes including uncorrected visual acuity, residual refractive astigmatism, and spectacle independency, which have been announced for both toric IOLs and multifocal toric IOLs, are estimated. The occurance of misalignment, the most important complication of toric IOLs, is defined. Finally, future developments, are discussed, in the field of toric IOLs.
