Purpose

To evaluate the long-term efficacy, safety, predictability, and stability of a foldable anterior chamber phakic intraocular lens (Artiflex) in eyes with ≥10-years of follow-up (F-U).

Setting

Instituto de Microcirugía Ocular (IMO), Barcelona, Spain.

Methods

Retrospective review of eyes undergoing Artiflex implantation from 2008-2011. 76 eyes (40 patients) with ≥10 years of F-U were included. Variables analyzed were preoperative, 1-month, 1-year, 5-years, and last F-U uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction, spherical equivalent (SE), endothelial cell count (ECC), and intraocular pressure (IOP). Descriptive statistics were performed for the collected variables and results reported following the Standard for Reporting Refractive Surgery Outcomes to include indices of efficacy, safety, predictability, and stability.

Results

Mean postoperative F-U was 10.67 ± 0.64 years. Mean preoperative SE was -8.26 ± 2.47 D. Efficacy and safety indices were 0.82 and 1.11, respectively. At the last F-U, 76% of eyes achieved a UDVA ≥20/40. No eye loss ≥2 lines of CDVA. Sixty-one percent were within ±0.50 D and 76% within ±1.00 D of the attempted SE correction. Ninety-five percent had ≤1.00 D of postoperative astigmatism, and 61% were within ±15° from the intended correction axis. At the final F-U, a statistically significant myopic progression of -0.56 ± 0.83 D was observed (p=0.01). Mean ECC loss was 12.2 ± 12.5%. IOP remained stable. Two eyes developed cataract after 10.3 years.

Conclusions

Long-term results demonstrate that Artiflex is effective, predictable, stable, and safe in eyes with ≥ 10 years of follow-up.
