Iris-fixated phakic IOL a viable alternative to femtosecond LASIK for moderate myopia

A foldable, iris-fixated phakic IOL and femtosecond laser-assisted LASIK proved similarly effective in correcting moderate myopia, a study found.

“Most patients with myopia between –6.00 and –9.00 D are candidates for excimer laser procedures or [phakic] IOL implantation, and the selection ultimately depends on several factors including patient age, corneal thickness, anterior chamber depth, corneal endothelial status, and patient and surgeon preference,” the study authors said.

The prospective study included 92 eyes of 46 patients with a mean age of 30.9 years who were randomized to undergo bilateral implantation of the Artiflex foldable iris-fixated phakic IOL (Ophtec) or bilateral femtosecond laser-assisted LASIK. The IntraLase FS laser (Abbott Medical Optics) was used for flap creation; stromal ablation was performed with the Visx S2 excimer laser (AMO).

All data used for analysis were gathered at 12 months postop.

Study results showed no statistically significant between-group differences in refraction. Spherical equivalent refraction was within 0.5 D of the target in 42 LASIK eyes and 41 phakic IOL eyes.

Data showed that 43 eyes in the LASIK group (93.5%) and 46 eyes in the phakic IOL group (100%) had uncorrected distance visual acuity of 20/25 or better; 17 eyes in the LASIK group (37%) and 19 eyes in the phakic IOL group (41.3%) had uncorrected distance visual acuity of 20/20.

All eyes had corrected distance visual acuity of 20/20. Four LASIK eyes (8.7%) and 23 phakic IOL eyes (50%) gained one line of corrected distance visual acuity. No LASIK eyes gained two or more lines of corrected distance visual acuity; four phakic IOL eyes (8.7%) gained two lines, the authors said.
