ABSTRACT
BACKGROUND:
To evaluate the efficacy and tolerance of two different foldable anterior chamber phakic intraocular lenses for high myopia.DESIGN:
A prospective interventional case series at the Eye Clinic, Kartal Training and Research Hospital, Istanbul, Turkey.PARTICIPANTS:
Sixty-two eyes of 31 patients received iris-claw lens (group 1) (Artiflex AC 401, Ophtec), and 43 eyes of 22 patients received angle-supported lens (group 2) (I-Care, Corneal).METHODS:
The mean preoperative spherical equivalents for group 1 and group 2 were -12.13 D and -18.95 D, respectively. Endothelial cell density was measured at day 1 and at 1, 3, 6, 12 and 18 months for follow ups. MAIN OUTCOMEMEASURES:
Percentage change in endothelial cell density and improvement in visual acuity.RESULTS:
At the 18-months follow up, uncorrected visual acuity improved to logMAR 0.37 ± 0.23 from 1.60 ± 0.10 in group 1, and logMAR 0.47 ± 0.14 from 0.70 ± 0.20 in group 2; best spectacle corrected visual acuity improved to logMAR 0.23 ± 0.22 from logMAR 0.36 ± 0.14) in group 1, and logMAR 0.29 ± 0.18 from logMAR 0.50 ± 0.20) in group 2 (P<0.001, in both groups). Mean decreased endothelial cell density was 241 cells/mm(2) (8.61%) and 223 cells/mm(2) (8.42%) at 18 months follow up in group 1 and 2, respectively (P=0.17) but significant in comparison to preoperative values for both groups (P<0.001).CONCLUSIONS:
Although both iris-claw and angle-supported lenses offer good refractive outcomes significant endothelial cell density was observed at 18 months follow up.
