“…Внедрение в клиническую практику бифокальных интраокулярных линз (ИОЛ) с двумя точками фокусировки обеспечивает достижение приемлемой остроты зрения вблизи и вдаль, но не на среднем расстоянии [2,3]. Для удовлетворения возрастающих нужд пациентов и получения высокой остроты зрения на среднем расстоянии были внедрены принципы моновидения и трифокальной интраокулярной коррекции [4][5][6][7][8][9][10]. Вместе с тем, несмотря на очевидные преимущества, данные методы имеют и ряд недостатков.…”

Aim. Analysis of the functional results of new IOL with an extended depth of focus implantation a in the short-term (6 months) follow-up period.Patients and methods. The prospective study included 27 patients (40 eyes) after bilateral (n = 12) or monolateral (n = 15) implantation of EDOF IOL Tecnis Symfony with an average follow-up period of 6.5 ± 0.2 (6–7) months. In all cases, IOL implantation was preceded by cataract phacoemulsification or removal of the transparent lens for refractive purposes. The age range was from 39 to 78 (60.6 ± 10.1) years. EDOF IOL Tecnis Symfony ZXR00 was implanted in 30 eyes, and toric EDOF IOL Tecnis Symfony ZXT100, ZXT150, ZTX225, and ZXT300 were implanted in 10 eyes in the presence of clinically significant astigmatism.Results. An increase in UCNVA from 0.18 ± 0.04 to 0.79 ± 0.11, UCIVA from 0.21 ± 0.07 to 0.89 ± 0.10, UCDVA from 0.24 ± 0.06 to 0.95 ± 0.16, BCNVA from 0.61 ± 0.05 to 0.80 ± 0.03, BCIVA from 0.58 ± 0.10 to 0.97 ± 0.19, and BCDVA from 0.65 ± 0.08 to 1.0 ± 0.06 (p < 0.05 in all cases). The spherical equivalent of refraction decreased from –4.5 ± 1.8 in the preoperative period to –0.18 ± 0.92 in the follow-up period of 6 months after implantation of the Tecnis Symfony ZXR00 IOL. In the group with toric IOLs, a decrease in the cylindrical component of refraction was shown from 1.33 ± 1.02 (modulo) to 0.61 ± 0.44 (modulo) during the maximum observation period. In all cases, the rotational stability of the implanted IOLs was noted. In 9 patients out of 24 (37.5 %), permanent or periodic optical phenomena were detected, of which 4 patients (16.7 %) had halos, 3 (12.5 %) had glare, and 2 (8.3 %) had difficulty driving in the dark. These side effects did not affect the overall patient satisfaction — 22 patients (91.7 %) rated the result of the operation as “excellent”, and 2 patients (8.3 %) — as “good”.Conclusion. The paper presents an analysis of the first experience in the Russian Federation of implantation of new IOLs with extended depth of focus and their toric version in 27 patients. Data on the effectiveness of this IOL for vision correction at all distances, low frequency of side optical phenomena, and high patient satisfaction are presented. Further comparative studies with other multifocal IOLs are needed.

Purpose To evaluate the visual performance of an extended depth of focus (EDOF) intraocular lens (IOL) for patient selection. Methods This prospective non-comparative case series evaluated fifty-two eyes (26 patients) after bilateral implantation of the Tecnis Symfony IOL. Exclusion criteria were previous ocular surgeries, corneal astigmatism of >1.5 diopter, and ocular pathologies or corneal abnormalities. Uncorrected (UCVA) and distance-corrected (DCVA) visual acuity (VA) in 4 m, 80 cm, 60 cm and 40 cm (logMAR), defocus curve, contrast sensitivity (CS) and a questionnaire on subjective quality of vision (QoV) were assessed after 3 months. Results UCVA was −0.02 ± 0.071 logMAR at 4 m, 0.01 ± 0.077 logMAR at 80 cm, 0.08 ± 0.187 logMAR at 60 cm and 0.22 ± 0.153 logMAR at 40 cm. Defocus curve testing showed a flat VA range from 0.00 to −1.50 D (−0.05-0.02 logMAR). At near distance from −2.0 to −2.5 D a dip of DCVA was observed (0.14-0.28 logMAR). CS under photopic and mesopic conditions without and with glare was 1.56 logCS, 0.86 logCS, 0.78 logCS, respectively. Spectacle independence was achieved in 100% for distance and intermediate vision and 71% of patients at near distance. Conclusion This EDOF IOL provides excellent intermediate and far (<0.1 logMAR) and acceptable near UCVA (<0.3 logMAR). Defocus curve testing confirmed an EDOF between far and intermediate distance and showed a dip at near distance. It provides good QoV, CS, high spectacle independence, perception of few optical phenomena, and particularly good night-driving capabilities.
