Implantation of a trifocal toric intraocular lens to a patient with pigment dispersion syndrome

Abstract

Aim. To present a clinical case of treatment of pigment dispersion syndrome by clear lens extraction and implantation of a toric intraocular lens in a patient with myopic astigmatism. 
 Methods. A 33-year-old patient with a diagnosis of moderate myopia, complex mild myopic astigmatism, pigment dispersion syndrome of both eyes. 
 Results. The first stage was laser peripheral iridotomy of both eyes. On follow-up pathological irido-zonular contact and increases intraocular pressure by 2 mm persisted. The second stage included clear lens extraction and implantation of a toric multifocal intraocular lens to both eyes. In 2 months, distance and near visual acuity was 1.0, intraocular pressure was normal, no pathological irido-zonular contact was observed according to the ultrasound biomicroscopy. 
 Conclusion. Implantation of an intraocular lens in patients with myopia and pigment dispersion syndrome is both a method of preventing pigment glaucoma and myopia correction; patients with pigment dispersion syndrome after peripheral iridotomy should monitor the state of the anterior segment of the eye and the effectiveness of the treatment by ultrasound biomicroscopy.
