Purpose. To demonstrate the effectiveness of single-step phacoemulsification of cataracts and antiglaucoma surgery in conditions of weakness of the zonular apparatus. Methods. Patient N., 67 years old, came to S. Fyodorov Eye Microsurgery Federal State Institution (Moscow) with complaints of decreased vision, increased intraocular pressure (IOP), and narrowing of the fields of view of the right eye. The diagnoses: OD Primary open-angle glaucoma 3v, Subluxation of the lens grade 1 OS Primary open-angle glaucoma 1a, OU Complicated cataract, Pseudoexfoliation syndrome. Carried out: autorefractokeratometry, visual acuity testing, computerized perimetry, biomicroscopy, gonioscopy, pneumotonometry, tonometry according to Maklakov, optical biometry. Considering the weakness of the lens zonules, the method of fixation of the intraocular lens (IOL) by optic capture technique was used. Results. Examination and evaluation one week post-operation: Visus 0.6 unc, IOP (pneumotonometry) 11 mmHg without hypotensive therapy; biomicroscopy: a calm eye with a well-expressed filtration bleb at the 12 o’clock position, well-adapted sutures, a transparent cornea of average depth, clear aqueous humor, moderate iris atrophy, round 3 mm pupil with pseudophakia at the pupil’s edge, IOL located in the capsular bag with haptics in the iridociliary groove, stable positioning. Fundus examination shows a pale optic nerve head, excavated with 0.8 cup-to-disc ratio, well-defined borders, narrowed vessels. Macular region appears normal. Conclusion. Combined cataract and glaucoma surgery in a patient with subluxated crystalline lens using the «optic capture» technique and Non-penetrating Glaucoma Surgery allowed preserving the correct and stable position of the IOL with normalization of intraocular pressure without the need for hypotensive therapy during a 1-year follow-up period. Key words: one-stage surgery, primary angle-closure glaucoma complicated by cataract, «optic capture»
