Experience with the Artisan phakic intraocular lens in Asian eyes.
OBJECTIVE
To investigate the efficacy and safety of implantation of an iris-claw phakic intraocular lens (PIOL), Artisan Myopia, in Asian eyes.


METHODS
Minamiaoyama Eye Clinic, Tokyo, Japan.


METHODS
Forty-four eyes of 32 Japanese patients and 1 Korean patient with high myopia had Artisan Myopia lens implantation to correct their refractive errors. Lens models, 5/8.5 or 6/8.5 (optic diameter/overall diameter), were chosen as standard lens model. A smaller lens model (5/7.5-Artisan Myopia Small) was implanted in eyes with corneal diameter less than 11.0 mm. Postoperative examinations were performed on 1 day, 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years after surgery. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, corneal endothelial cell counts, intraocular pressure, and complications were evaluated.


RESULTS
Artisan Myopia Small lenses were implanted in 4 eyes (9.1%) and 8.5 mm diameter lenses were implanted in 40 eyes. Preoperative UCVA (logMAR) improved from 1.57 to 0.09 at 1 month after surgery and no regression was observed thereafter. Postoperative manifest refraction was -1.02 +/- 0.87 D (-3.25 to -0.00 D), and within 1.0 D in 20 eyes (55.6%), within 2.0 D in 32 eyes (88.9%) at 1 month after surgery, and stable during the follow-up period. The final BCVA decreased 2 lines in 2 eyes (4.5%) due to progression of age-related cataract. No serious complications such as angle closure or progressive endothelial cell loss were observed.


CONCLUSIONS
Implantation of an Artisan iris-claw PIOL implantation may be a safe and effective procedure for Asian eyes.
