Abstract Details

Purpose:

To evaluate the outcomes of Collagen copolymer toric phakic intraocular lens in high hyperopia and compound hyperopic astigmatism.

Setting:

Dunya Eye Hospital, Istanbul ,Turkey

Methods:

13 eyes (7 patients) with high hyperopia and compound hyperopic astigmatism , Preoperative hyperopia was between 5.50 and 11.50 D (mean 6.81D), astigmatism was between 0.50 and 2.75D (mean 1.43 D). implantation of Collagen copolymer toric phakic intraocular lens (pIOL) .In all eyes, anterior chamber depth (ACD) was higher than 3.00 mm. The mean follow up time was 30.2 months (24-35 months) Main outcome measures were UCVA, BCVA , manifest refraction, anterior chamber depth (ACD), axial length (AL), adverse effects, intraoperative and postoperative complications and intraocular pressure(IOP) evaluation.

Results:

Baseline manifest refraction spherical equivalent (MRSE) changed from 6.81 D (+/-1.57) to 0.53 D (+/-0.28) postoperatively. The mean refractive cylinder changed from 1.43 D (+/-0.73) to 0.36 D (+/-0.09) postoperatively. The mean decimal UCVA was significantly improved from 0.26 to 0.78 (P<.0001) . The postoperative UCVA of 11 eyes (84.6%) was equal to preoperative BCVA. Postoperative UCVA of 2 eyes (15.4%) gained 1 line of preoperative BCVA. No eye lost a line of BCVA. No intraoperative or postoperative complications occurred.

Conclusions:

Toric PIOL implantation is an effective, predictable and safe treatment in correction of high hyperopia and compound hyperopic astigmatism. Longer term studies are required for further evaluation and comparison with other methods. However a long-term follow-up of a larger population study is required to validate these findings
