Abstract Details

Purpose:

To evaluate the safety and refractive efficiency after posterior chamber diffractive implantable phakic contact lens (IPCL) surgery was performed.

Setting:

Clínica de Ojos Dr. Nano, Olivos, Buenos Aires, Argentina.

Methods:

A prospective non-randomized case-series study was performed in 54 myopic eyes from 27 patients who underwent diffractive IPCL surgery. The corneal endothelial cell density (ECD), central corneal thickness (CCT), intraocular pressure (IOP), vault, uncorrected distance (UDVA), spherical equivalent (SE) and defocus curve, were evaluated 12 months after surgery. By slit-lap, the presence of cataract was evaluated during postoperative follow-up.

Results:

The mean age was 47 ±2.62 years-old. The mean SE decreased from -5.95 ±2.56 D pre-operatively to -0.25 ± 0.25 D at 12 months after surgery. The UDVA achieved was 20/20 in 24.1%, 20/25 in 74.1%, remaining eyes obtained 20/32, and no eye lost lines of vision. The binocular defocus curve was 0.06 ±0.05 logMAR for -3.0 D of defocus, 0.11 ±0.04 logMAR for -1.5 D of defocus and 0.08 ±0.03 logMAR for 0 D of defocus. The mean ECD decreases 1.43% and the mean CCT increases 0.06% at 12 months post-operative, without a statistically significant difference (p: 0.28 and p: 0.93 respectively). No difference (p: 0.86) in the vault was observed at 6 months vs.12 months, as well as between IOP measurements (p: 0.22). Non-intra or postoperative complications occurred, and specifically, cataracts did not develop.

Conclusions:

Diffractive IPCL was implanted safely. The corneal endothelial CD, CCT, vault, and IOP remained stable 12 months after surgery. Visual acuity for distance, intermediate and near sight could be achieved without spectacles.
