목적 : To compare the effectiveness of toric foldable iris-fixated phakic intraocular lens (pIOL) implantation and non-toric foldable iris-fixated pIOL implantation with limbal relaxing incisions (LRIs) for correcting moderate-to-high astigmatism in myopic eyes.
방법 : Medical records of 146 patients (195 eyes) with myopic astigmatism who underwent toric foldable iris-fixated pIOL implantation (toric group; 94 eyes in 65 subjects) or non-toric foldable iris-fixated pIOL implantation with concurrent LRIs (LRI group; 101 eyes in 81 subjects) were retrospectively reviewed. For subgroup analysis, two groups were subdivided according to preoperative astigmatic severity (moderate, 2.00 to <3.00 diopters [D]; high, 3.00–4.00 D). Visual and astigmatic outcomes were compared 6 months postoperatively.
결과 : The uncorrected distance visual acuity was at least 20/25 in 100% and 98% of the toric and LRI group eyes, respectively. The toric group had lower mean residual cylindrical error (−0.67 ± 0.39 D vs. −1.14 ± 0.56 D; P < 0.001) and greater mean cylindrical error change (2.17 ± 0.56 D vs. 1.63 ± 0.72 D; P < 0.001) than the LRI group regardless of the preoperative astigmatic severity. The mean correction index (1.10 ± 0.16 vs. 0.72 ± 0.24; P < 0.001) and success index (0.24 ± 0.14 vs. 0.42 ± 0.21; P < 0.001) also significantly differed between the groups.
결론 : Both the surgical techniques considerably reduce astigmatism and have comparable visual outcomes. However, toric foldable iris-fixated pIOL implantation is more reliable for correcting moderate-to-high astigmatism in myopic eyes.
