A retrospective study was conducted on 10 eyes of 10 patients who had undergone DALK and subsequently underwent toric RIL implantation. The patients were followed up over a period of 1 year. The parameters compared were uncorrected and best corrected visual acuity, spherical and cylindrical acceptance, mean refractive spherical equivalent, and endothelial cell counts.
There was a significant improvement (P < 0.05) from preoperatively to 1 month postoperatively in the mean log of minimum angle of resolution (logMAR) uncorrected distance visual acuity (UCVA; 1.1 ± 0.1 to 0.3 ± 0.1), spherical refraction (5.4 ± 3.8 to 0.3 ± 0.1 D), cylindrical refraction (5.4 ± 3.2 to 0.8 ± 0.7 D), and MRSE (7.4 ± 3.5 to 0.5 ± 0.4 D). Three patients achieved spectacle independence for distance vision with a residual MRSE less than 1 D in the other cases. A stable refraction was maintained up to 1 year follow-up in all cases. There was a 2.3% mean decline in endothelial cell counts at 1 year of follow-up. No intraoperative or postoperative complications were seen in any case up to 1 year of follow-up.
RIL implantation is an effective and safe procedure for the correction of high ametropia post-DALK.
UNASSIGNED:对10例接受DALK并随后接受复曲面RIL植入的患者的10只眼进行了回顾性研究。对患者进行为期1年的随访。比较的参数是未矫正和最佳矫正视力,球形和圆柱形验收,平均折射球面当量,和内皮细胞计数。
UNASSIGNED:从术前到术后1个月,最小分辨角(logMAR)的平均对数未矫正视力(UCVA;1.1±0.1至0.3±0.1)均有显着改善(P<0.05),球面折射(5.4±3.8至0.3±0.1D),圆柱折射(5.4±3.2至0.8±0.7D),和MRSE(7.4±3.5至0.5±0.4D)。在其他情况下,三名患者实现了远距视力的眼镜独立性,残余MRSE小于1D。在所有情况下,稳定的屈光维持长达1年的随访。随访1年时内皮细胞计数平均下降2.3%。随访1年,均未见术中或术后并发症。
UNASSIGNED:RIL植入是纠正DALK术后高度屈光不正的有效且安全的程序。
