Different results of phakic intraocular lenses (PIOL) studies.
| Authors | Country | Design (eyes) | Follow-up(m) | Results |
|---|---|---|---|---|
| Kamiya K et al. (2008)114 | Japan | - (4) | – | Preoperatively, manifest refraction was −10.00–6.00 × 100 in case 1 and -8.00–2.75 × 100 in case 2. Postoperatively, the manifest refraction was +0.50–1.00 × 90 in case 1 and -0.25–1.25 × 100 in case 2. |
| Venter J. (2009)115 | UK | Retrospective study (18) | 12 | The implantation of Artisan in patients with keratoconus and myopia, 94% of eyes had a UCVA of 0.63 or better and 72% of eyes gained one or more lines of BCVA. |
| Güell JL et al. (2008)127 | Spain | Case series (399) Four groups |
1,3,60 | Group 4 had a mean preoperative cylinder of −3.24 ± 1.02 D, which decreased to −0.83 ± 0.74 D postoperatively. Implantation of iris-claw PIOLs is an effective procedure. |
| Al-Dreihi MG et al. (2013)128 | Syria | Case report | 12 | Artisan iris-fixated Toric phakic intraocular lens implanted for the correction of high astigmatism following deep anterior lamellar keratoplasty in a 23-year-old woman. UCVA and BCVA were 20/20 after one-year follow-up and refractive cylinder was −1.00 D and endothelial cell count was 1827 cells/mm2. |
| Alfonso JF et al. (2014)129 | Spain | Case series (35) | 12 | Mean sphere was −5.46 ± 4.17 (SD) and mean cylinder was −3.14 ± 1.19 D. Postoperatively, the mean decimal UCVA was 0.89 ± 0.16 and 43% of eyes gained 1 or more lines. More than 50% of eyes had a Snellen UCVA of 20/20. |
| Venter J (2015)130 | UK | Case series (103) Two groups |
60 | The mean BCVA improved from 0.51 ± 0.15 logMAR to 0.34 ± 0.16 logMAR (P < 0.001) in Group 1 and from 0.54 ± 0.17 logMAR to 0.46 ± 0.14 logMAR in Group 2 (P < 0.005). The iris-fixated PIOL was effective option for improving visual acuity in amblyopic eyes. |
| Qin Q et al. (2017)131 | China | Case series (9) | 18 | UCVA and BCVA improved after 6 month after TICL implantation following DALK surgery. The deviation of TICL axis was less than 10° and no severe complication after surgery was found. |
| Tiveron MC Jr et al. (2017)132 | Brazil | Retrospective case series (24) | 12 | UCVA was better in 88% of eyes after Toric Iris Claw phakic intraocular lens implantation following DALK surgery 92% of eyes had spherical equivalent ≤±1.00D with efficacy and safety 0.93 and 1.00, respectively after 12 month. Mean endothelial cell loss was 6.10% and no severe complication was found after surgery. |
BCVA: Best corrected visual acuity, UCVA: Uncorrected visual acuity, D: Diopter, logMAR: The logarithm of the minimum angle of resolution, PIOL: Phakic intraocular lens, TICL: Toric implantable collamer lens, DALK: Deep anterior lamellar keratoplasty.
