| Popis: | Purpose: to study the results of toric intraocular correction following a surgical treatment of cataract in a 69-year-old patient with the 2nd stage of keratoconus by Amsler-Krumeich classification with intrastromal corneal segments implanted. Methods. During the first visit, the patient had 0.1 best corrected visual acuity (BCVA). The choice of an intraocular lens Tecnis Toric IOL (Abbott, USA) and the optimization of the planned operation was performed on the website of the IOL manufacturer according to the data obtained by partial coherence optical biometry IOL-Master (Carl Zeiss, Germany), dual Scheimpflug Placido keratotopography on the Analyzer of anterior eye segment Galilei G6 (Ziemer, Switzerland), and keratotopography on Magellan Mapper (Nidek, Japan).Results. 6 months after the implantation of intrastromal corneal ring segments, BCVA was 0.2. On the next day after cataract phacoemulsification with implantation of a toric IOL, BCVA was 0.4. 2 years after the implantation of intrastromal corneal segments and phacoemulsification with implantation of a toric IOL, the patient's BCVA was 0.7. Conclusions. We obtained high refractive outcome of a combined staged use of intrastromal corneal segments and correction of aphakiaby a toric IOL in a patient with stable stage 2 keratoconus. A two-year follow-up showed that BCVA and the position of the toric IOL axis remained stable after surgery. For citations: Oganesyan O.G., Romanova L.I., Milash S.V., Penkina A.V.
