Purpose. To evaluate clinical and functional results of implantation of a new hydrophobic acrylic monofocal IOL in a preloaded injector.Methods. The prospective study included 60 patients (66 eyes) after Hoya iSert® 250/251 IOL implantation (31 patients, 35 eyes, group 1) and a new Hoya Vivinex Multisert® XY1-SP IOL (29 patients, 31 eyes, group 2). The mean age was 75.1 ± 7.9 years. The mean follow-up period after surgery was 3.1 ± 0.4 months. IOL viscoimplantation was performed in 100 % of cases in group 1, in group 2 — in 45.1 % of cases, and in 54.9 % — hydroimplantation was performed. Intraoperatively, the size of the corneal incision was measured with a ruler before and after IOL implantation. IOL optic power was calculated with SRK/T and Barrett Universal formulas. In the postoperative period, surgically induced astigmatism was assessed.Results. In both groups, there was a statistically significant (p < 0.05) increase of UCDVA from 0.28 ± 0.09 in the preoperative period to 0.70 ± 0.17 3 months after surgery in group 1 and from 0.24 ± 0.10 in the preoperative period to 0.84 ± 0.18 3 months after surgery in group 2. Slightly lower values of UCDVA in group 1 may be associated with a higher level of SIA in this group. Similar dynamics were shown for the BCDVA (from 0.52 ± 0.21 before surgery to 0.95 ± 0.19 after 3 months of follow-up in group 1 and from 0.55 ± 0.20 before surgery to 0.98 ± 0.21 after 3 months of follow-up in group 2). No differences were found between the studied groups. After IOL implantation, there was an increase in incision size to 2.40 ± 0.12 mm in group 1 and 2.10 ± 0.08 mm in group 2 (p = 0.04). In group 1, the mean SIA after 3 months of observation was 1.10 ± 0.16 D and in group 2, 0.48 ± 0.07 D (p = 0.0007).Conclusion. This study presents the first domestic experience with the implantation of a new monofocal hydrophobic acrylic Hoya Vivinex IOL in a Multisert® preloaded injector. A comparative analysis of implantation results with monofocal Hoya 250/251 IOLs in an Isert® injector was performed. The advantage of the new IOL implantation in reducing the incidence of surgically induced astigmatism was shown.

In modern ophthalmic surgery, an intraocular lens (IOL) is commonly implanted into the patientʼs eye with an IOL injector. Many injectors are available, showing various technological differences, from the early manually loaded injector systems to the modern preloaded injectors. This review aims to give a concise overview of the defining characteristics of injector models and draws attention to complications that may occur during IOL implantation. One can differentiate injectors according to their preoperative preparation (manually loaded or preloaded), their implantation mechanism (push-type or screw-type or combined or automated), the size of the nozzle tip, the presence of an insertion depth control feature, and the injectorʼs reusability. Potential complications are IOL misconfigurations such as a haptic-optic adhesion, adherence of the IOL to the injector plunger, an overriding plunger, uncontrolled IOL rotation, a trapped trailing haptic, or damage to the IOL. Additionally, during IOL implantation, the nozzle can become damaged with scratches, extensions, cracks, or bursts to the tip. While these complications rarely produce long-term consequences, manufacturers should try to prevent them by further improving their devices. Similarly, surgeons should evaluate new injectors carefully to ensure the highest possible surgical safety.
