THE FIRST EXPERIENCE OF HIGH MYOPIA CORRECTION BY POSTERIOR CHAMBER PHAKIC IOL-3 IMPLANTATION
Purpose. To evaluate an adaptation ability of posterior chamber phakic IOL (pIOL-3) to a lower diameter of sulcus ciliaris in eyes with high myopia.Material and methods. The pIOL-3 was implanted in 3 eyes of 2 patients with high myopia (spherical component: -22.5D), where the sulcus ciliaris diamete...

| Summary: | Purpose. To evaluate an adaptation ability of posterior chamber phakic IOL (pIOL-3) to a lower diameter of sulcus ciliaris in eyes with high myopia.Material and methods. The pIOL-3 was implanted in 3 eyes of 2 patients with high myopia (spherical component: -22.5D), where the sulcus ciliaris diameter was lower than «pIOL-3» length to 0,5mm. The uncorrected visual acuity (UCVA) did not exceed 0.01, the best corrected visual acuity (BCVA) – 0.4. The followup was 1 year.Results. There were no complications intra- and postoperatively in all cases. The UCVA improvement up to 0.1 was noted already first hours after pIOL-3 implantation. The BCVA was limited by available alterations of macular area and did not exceed 0.4. The average loss of posterior epithelial cells did not exceed 2%. Any impact of performed surgical intervention on intraocular pressure was not revealed. The ultrasound biomicroscopy showed a good stable central pIOL-3 localization in the posterior chamber of the myopic eye without any excessive vaulting toward the anterior chamber within the entire follow-up.Conclusion. Constructive features of the pIOL-3 allow to avoid an excessive vaulting in cases of its implantation when the diameter of sulcus ciliaris is lower than the pIOL length. The pIOL-3 implantation in case of high myopia provides an achievement of maximum visual acuity already first hours after surgery. |
