An important point in cataract surgery, especially in view of performing operations on an outpatient basis and increasing surgical activity, is the need to minimize trauma to the delicate structures of the anterior segment of the eyeball, reduce the likelihood and number of complications and obtain high functional results in the shortest possible time. Purpose of the study: to carry out a comparative assessment of the flowmetry indices dynamics in accordance with the calculation of the tolerant intraocular pressure (TIAP) in patients after femtolaser cataract extraction (FLEK) and ultrasound FEC. The study included 125 patients aged 50 to 60 years, who underwent surgery for cataracts. The patients were divided into two groups. Standard ultrasound PE was performed in patients of group 1, and FLEK in patients of group 2. All patients underwent a standard ophthalmological examination, as well as flowmetry, reflecting the state of the volumetric ocular blood flow (OVF), with the calculation of the tolerant intraocular pressure (TIОP) index, which serves to determine the individually-adequate ophthalmotonus and ocular blood flow. The study was carried out before the operation, after 1 day, on the 3rd, 7th days and 1 month after the operation. Analysis of the data indicates that both during phacosurgery by the method of traditional ultrasound PE and hybrid PE, a transient increase in IOP occurs, which is most pronounced on the 1st and 3rd day. With a transient increase in IOP, a decrease in the OVF indicator was noted, respectively, the calculated TIOP indicator also changed, but the excess was no more than 3–5 mm Hg.
