This pseudo-experimental, prospective, and longitudinal pilot study was conducted to characterize the optical and visual changes occurring in the short-term wear of a hydrophilic contact lens (CL) based on extended focus technology (EDOF). A total of 30 eyes of 15 children (age, 6–16 years) were fitted with the EDOF CL Mylo (Mark’ennovy Care SL), performing an exhaustive follow-up for one month evaluating changes in visual acuity (VA), accommodation, binocularity, ocular aberrometry, visual quality, pupillometry, keratometry and biometry. Far and near VA with the CL improved progressively (p < 0.001), obtaining mean final binocular values of −0.08 ± 0.01 and −0.07 ± 0.01 LogMAR, respectively. There was a mean reduction in the accommodative LAG of 0.30 D (p < 0.001), without associated alterations in the magnitude of the phoria and fusional vergences (p ≥ 0.066). A controlled but statistically significant increase (p ≤ 0.005) of ocular high order aberration (HOA) root mean square (RMS), primary coma RMS, primary spherical aberration Zernike term and secondary astigmatism RMS was found with the CL wear. In conclusion, the EDOF CL evaluated provides adequate visual acuity and quality, with associated increased of several HOAs and a trend to reduction in the accommodative LAG that should be confirmed in future studies.

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.
