Clinical Outcomes of Tetraflex Accommodative Intraocular Lens Implantation 2 Years after Cataract Surgery for Presbyopia

Aims: To evaluate the 24 month visual and accommodative outcomes of Tetraflex accommodative intraocular lens (AIOL).

Study Design: Retrospective, interventional case series.

Place and Duration of the Study: Bakirkoy Training and Research Hospital, Istanbul, Turkey, between December 2011 and April 2012.

Material and Methods: The patients who underwent cataract surgery with phacoemulsification, and in whom Tetraflex AIOL was implanted and who completed the follow-up period of 24 months were included. Uncorrected (UCDVA) and best corrected distance visual acuities (BCDVA) were evaluated pre- and post-operatively, and uncorrected (UCNVA), distance-corrected (DCNVA) and best corrected near visual acuities (BCNVA) and spherical equivalent (SE) refraction errors were evaluated post-operatively only. Accommodative amplitude was measured with a subjective and objective method and at post-operative month 3, 6 and 24.

Results: A total of 16 eyes of 14 patients were included. The mean baseline, month 3, 6 and 24 UCDVA of the patients was 0.95 ± 0.47, 0.11 ± 0.14, 0.14 ± 0.16 and 0.14 ± 0.17 LogMAR, respectively. The mean month 3, 6 and 24 UCNVA was 0.49 ± 0.16, 0.54 ± 0.15 and 0.51 ± 0.16 LogMAR, respectively. The mean amplitude of accommodation by subjective defocus method was -1.06 ± 0.30, -1.14 ± 0.27 and -1.13 ± 0.27 D and the average pilocarpine-induced IOL mobility (∆ ACD) was 0.34 ± 0.16 mm, 0.37 ± 0.16 mm and 0.36 ± 0.15 mm at postoperative month 3, 6 and 24, respectively.

Conclusion: The Tetraflex AIOL implantation seemed a safe and effective treatment option for presbyopia.
