PURPOSE: To evaluate safety, efficacy, predictability, stability, complications, and patient satisfaction after Artisan phakic intraocular lens (IOL) implantation followed by laser in situ keratomileusis (LASIK) for the correction of high hyperopia.

SETTING: Instituto Oftalmólogico de Alicante, Alicante, Spain.

METHODS: This prospective trial included 39 eyes with a mean preoperative spherical equivalent (SE) of 7.39 diopters (D) +/- 1.30 (SD) and a cylinder between 0 and -4.25 D. The Artisan iris-fixated phakic IOL (Ophtec) for hyperopia was implanted, and LASIK was performed 6 to 8 months later. The best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), refraction, endothelial cell loss (ECL), endothelium morphologic analysis, and patient satisfaction were recorded. The minimum follow-up was 12 months.

RESULTS: At 1 year, 37 eyes (94.9%) were within +/-1.00 D of emmetropia and 31 eyes (79.5%) were within +/-0.50 D. Thirty-five eyes (89.7%) achieved a UCVA of 0.5 or better. There was a statistically significant decrease in BCVA after phakic IOL implantation, but this effect was corrected after LASIK. Nine eyes (23.1%) lost 1 line of BCVA; 7 eyes (17.9%) gained at least 1 line. One eye (2.6%) showed a change in SE greater than 1.0 D over the follow-up period. The mean ECL was 10.9%, but morphologic analysis suggested no additional damage caused by LASIK over that produced by phakic IOL surgery. Overall patient satisfaction was high.

CONCLUSIONS: The combination of Artisan phakic IOL implantation and LASIK safely, predictably, and effectively reduced high hyperopia. A loss of 1 line of BCVA should be expected in about one third of eyes implanted with this IOL. Halos and glare at night remain a potential problem.
