AIM: To evaluate the safety and effectiveness of phacoemulsification and Tetraflex accommodative intraocular lens(IOL)in providing both enhanced distance visual acuity and near visual acuity.

METHODS: Thirty patients(30 eyes)with age-related cataract underwent phacoemulsification and were implanted with Tetraflex IOL, while other 30 patients(30 eyes)were implanted with Akreos Adapt IOL. Prospective data collection included both uncorrected distance visual acuity(UCDVA)and uncorrected near visual acuity(UCNVA)testing, manifest refraction, best-corrected distance visual acuity(BCDVA), distance corrected near visual acuity(DCNVA), and the amplitude of accommodation. Intraoperative and post operative complications also were reported.

RESULTS: Six months after surgery, the uncorrected distance, corrected distance, and corrected near visual acuity had no significant difference between two groups. The UCNVA, DCNVA and the amplitude of accommodation of Tetraflex group were better than Akreos Adapt group(t=2.427, 8.687, 15.158, P=0.023, 0.000, 0.000).

CONCLUSION: The Tetraflex accommodating IOL is safe and effective. It provides enhanced near vision with good distance vision 6 months after surgery.
