New anterior chamber lens has good early results

NICE, France — The Safety Flex Phakic anterior chamber lens seemed to be effective and safe in correcting high myopia, according to an early study presented here.

Giovanni Alessio, MD, MG, and colleagues discussed their results with the lens in a poster presentation at the European Society of Cataract and Refractive Surgeons meeting. The study evaluated efficacy, predictability, safety, stability and quality of vision with the Safety Flex Phakic 6H2 lens (Ophthalmic Innovations International) in 21 eyes of 11 patients.

After implantation of the anterior chamber lens, the authors said there was no loss of Snellen best corrected visual acuity in any eyes. Uncorrected visual acuity improved in all eyes. Spherical equivalent refraction improved from a mean of –13.8 D to –0.68 D. Refractive correction was stable from 2 days after surgery until the final follow-up examination at a mean of 11 months.

No complications were reported in the study. The authors noted that previous studies have shown a possibility of glare, pupil ovalization and other complications with the Phakic 6H2 lens, an older model from OII.

Endothelial cell loss was noted to be 2% at 2 months after surgery. The authors noted a progressive increase in cellular density in later follow-up.
