PHAKIC POSTERIOR CHAMBER INTRAOCULAR LENSES FOR THE CORRECTION OF HIGH MYOPIA

BACKGROUND: This article evaluates the benefits and risks of silicone intraocular lenses (IOLs) implanted just anterior to the surface of the crystalline lens. METHODS: In this pilot study, 8 silicone IOLs were implanted into the posterior chambers of 8 phakic, myopic eyes (-8.00 to -20.00 diopters [D]) under local anesthesia through a 6-mm corneal incision. RESULTS: Five of the eyes (62.5%) had a spherical equivalent refraction within +/-1.00 D and all were within +/-1.50 D of the attempted correction. The spectacle-corrected visual acuities were improved postoperatively in all eyes. Anterior chamber depths were decreased with a mean depth of 0.288 mm, Slight decentrations were observed in three eyes without any optical problems, CONCLUSION: Phakic posterior chamber lenses are a promising intervention in highly myopic patients, especially in anisometropia. Further study is needed to prove the reliability of this technique.
