Clinical features of removing phakic intraocular lenses in cataract at high myopia
Abstract
Purpose: Development and an assessment of efficiency of a technique of phakic intraocular lenses (FIOL) at cataract phacoemul- sification.Methods: 25 FIOL, a pupillary lens RSC-3, a posterior chamber lens, production of MNtK, Russia, and posterior chamber lens ICL S4 StAAR were removed. Before complex surgical intervention (FIOL + phacoemulsification) were carried out standard ophthalmo- logic examination, and also automatic detection of density of endothelial cells.Results: the developed technique of removal of FIOL included subconjunctival anesthesia, formation of a corneal tunnel, filling of the anterior chamber viscoelastic, FIOL mobilization, removal of the bottom haptic element in the anterior chamber, removal of the top haptic element in the of anterior chamber, FIOL removal. In the early postoperative period in 8% transitory hypertensia was observed, in one case (4%) cornea hypostasis developed. In 92.4% of cases of the maximal visual acuity with correction was corresponded to the planned. Loss of endothelial cells after operation made 4.8% that in full corresponds to standard loss of cells after not complicated phacoemulsification.Conclusion: the technique of removal of FIOL developed as part of this research allows enough effectively and to carry out safelyto patients surgical treatment of the complicated cataract with a phakic intraocular lenses explantation.
