Abstract Details
Purpose:
To report the long- term results of topic phakic intraocular lens (pIOL) implantation to correct myopic astigmatism in patients with keratoconus with or without additional traitment.
Setting:
Instituto de Microcirugía Ocular , Barcelona, Spain.
Methods:
For 13 years , 3 different types of treatment were performed in eyes with proven progressive
keratoconus 1) Cross-linking, 2) ICRS, 3) KP. Some of them , once refraction and topography stabilized, toric Artiflex- Artisan pIOL implantation was performed to correct residual myopic astigmatism. A complete ophthalmologic examination, including manifest refraction, uncorrected and corrected distance visual acuities, biomicroscopy, tonometry, fundoscopy, keratometry, corneal tomography, and central endothelial cell count, was performed before each procedure and postoperatively at 3 months and at 6 months. Main outcome measures were accuracy and stability of the spherical equivalent and cylinder, keratometry, distance visual acuities,
Results:
The median follow-up in the 51 patients ( 69eyes) was 36.9 months +/-15.0 . The median interval between corneal treatment and pIOL implantation was 3.9 +/-0.7 months. Fifty five eyes(80%) were within +/-0.50 diopter of the attempted SE correction and 51 eyes (74%) were
within +/-1.00 D of the attempted cylinder correction. The mean difference in simulated keratometry between preoperatively and the last follow-up was 0.17 +/-0.45 D (range 0.55 to1.45 D). The postoperative UDVA was 20/40 or better in 64 eyes (94%). No eye lost lines of CDVA. No significant decrease in central ECC occurred ( P>.05).
Conclusions:
Toric iris-claw pIOL implantation is an efficient tool to safely correct the myopic astigmatism in stable keratoconus, specially in those patients that do not tolerate a contact lens due to anatomical causes or other causes.
