Abstract
Astigmatism is a common form of refractive error.For patients who also have cataracts,implanting a Toric intraocular lens(Toric IOL)offers an effective solution.However,in patients with compromised integrity of the capsular bag,Toric IOL implantation encounters the dual challenges of inadequate capsular support and difficulty in maintaining lens stability.Our article presents a systematic review of novel fixation strategies for Toric IOLs in patients with lens dislocation.It delves into an analysis of the technical characteristics of anterior chamber intraocular lenses(ACIOLs),transscleral suture fixation(TSF),intrascleral IOL fixation,and intraocular implant materials.Among these options,ACIOLs were once the preferred choice for implantation when capsular bag support was insufficient,primarily relying on the integrity of the anterior chamber structure.However,their use has gradually waned due to concerns over corneal endothelial damage.Transscleral suture fixation is more widely applied,and several small-scale cohort studies have validated the long-term effectiveness of this approach for Toric IOL fixation.Nevertheless,complications related to sutures remain a cause of concern.Scleral intrascleral fixation utilizes the IOL haptic as an anchor point.The specially designed Carlevale IOL performs exceptionally well with this technique,and its Toric model is particularly adept at correcting astigmatism,showing great potential.Moreover,advancements in intraocular implant materials,such as capsular tension rings(CTRs)and capsular hooks,have enhanced surgical success rates in cases of subluxated lenses,with long-term follow-up confirming the stability of the IOL stability.Furthermore,the combined use of implantable capsular hooks and CTRs facilitates the repositioning of late-displaced IOL-capsular bag complexes.关键词
