Summary:
Abstract. Objective: to analyze the results of implantation of toric posterior chamber phakic intraocular lenses (FIOL) in patients with high-grade myopia with astigmatism and high-grade refractive amblyopia. Material and methods. A toric posterior chamber FIOL was implanted in 52 eyes with a high degree of myopic astigmatism. Of these, 10 are with refractive amblyopia of a high degree. Results. Visual acuity on the first day after surgery was 0.93±0.06, in 7 days, 1 and 6 months — 0.97±0.05. The relative accommodation reserve after surgery in 1 month increased to 5.42±0.62D. The visual acuity of the amblyopic eye on the first day after surgery was 0.46±0.05, in 7 days — 0.52±0.07, in 1 month — 0.75±0.07 and in 6-12 months 0.78±0.07. The absolute accommodation reserve of the amblyopic eye at 6 months was 5.15±0.64D. Unstable binocular vision was revealed in 10 patients with amblyopia. Analysis of postoperative refraction after 12 months showed that emmetropic refraction was achieved in 45 eyes, myopic in (-) 0.25D — in 5, myopic in (-) 0.5D — in 2 eyes. Conclusion. Implantation of toric posterior chamber FIOL in patients with high-grade myopia and astigmatism, refractive amblyopia is justified: visual acuity improves, accommodation is preserved, binocular vision is restored, refractive effect is stable and a short rehabilitation period.
