Abstract Details

Purpose:

To evaluate the efficacy, predictability, security and stability of a posterior chamber Implantable Collamer Lens phakic intraocular lens (ICL) with a central flow design (Visian V4C) to correct myopia after two years of follow up.

Setting:

Department of Ophthalmology, Q Vision, Vithas Vírgen del Mar Hospital, Almería (Spain).

Methods:

Series of cases in which myopic patients who were implanted a spherical phakic lens Visian V4C with a central flow design of aqueous humor through its central hole were included; avoiding the need of iridotomy. In all patients included, uncorrected (UDVA) and corrected visual acuity (CDVA), refraction, spherical equivalent, mean pachymetry, intraocular pressure (IOP), the endothelial cell count, the anterior chamber depth (ACD) and the sulcus - sulcus distance were measured. After surgery, the uncorrected and corrected visual acuity, refraction, spherical equivalent, intraocular pressure, endothelial cell count and complications were evaluated in a month, 6 months, a year and 2 years.

Results:

This study involved 39 patients (63 eyes) with a mean age of 31.8 ± 7.05 years (range 19-46 years). The mean postoperative spherical equivalent was (-0.12 ± 0.22) dioptres per month and it was constant throughout the follow-up. The UDVA in 60 % of eyes remained off the preoperative CDVA, 24 % of eyes gained one line and 16% gained two or more lines. About IOP, 30% of the eyes had a decrease of 1 mm Hg, 40% was constant, 20% increase in 1 mm Hg and 10% at 2 mm Hg. The endothelial cell count showed no statistically significant losses. There was no postoperative complication, no need to explant or replacement of the lens.

Conclusions:

Visian ICL lens V4C is useful for a effective correcting moderate and high myopia, predictable, safe and stable manner.
