Visual and Refractive Outcomes of Phacoemulsification with Implantation of Accommodating versus Standard Monofocal Intraocular Lenses.

PURPOSE: To compare distant and near visual function after cataract surgery with implantation of Crystalens HD or Tek-Clear as accommodating intraocular lenses (IOLs), versus SA60AT as a standard IOL.

METHODS: The study included 62 eyes of 58 patients divided into three groups using three different IOLs: Crystalens HD (Bausch and Lomb, NY, USA), Tek-Clear (Tekia, CA, USA) and SA60AT (Alcon, TX, USA) were implanted in 23, 14 and 25 eyes, respectively. Corrected distant visual acuity (CDVA), uncorrected and distance corrected near visual acuities (UCNVA and DCNVA), near point of accommodation (NPA), spectacle freedom and patient satisfaction were assessed six months postoperatively and compared between the three groups.

RESULTS: After 6 months, all patients showed significant improvement in CDVA with no significant difference among the study groups. However, UCNVA and DCNVA were significantly better in patients implanted with accommodating IOLs. NPA was closest in the Crystalens HD group, followed by Tek-Clear and monofocal SA60AT (P < 0.001). Patients with accommodating IOLs were more likely to become spectacle free and satisfied with their near vision as compared to subjects receiving a monofocal IOL.

CONCLUSIONS: Accommodating IOLs (Crystalens HD and Tek-Clear) effectively reduce the necessity for spectacles after cataract surgery.
