Russian Experience of Using Different Types of Preloaded Intraocular Lens Delivery System

Abstract

Objectives: To obtain information on the frequency of using preloaded IOL delivery system, the time of the IOL implantation procedure, the convenience of using various preloaded systems, the incidence of complications and the overall level of satisfaction during the work by ophthalmologists during a survey of experts.Methods. A survey was conducted among 14 Russian experts from different regions who already have practical experience with the following preloaded IOL implantation systems: RayOne® Aspheric (RAO600C), iSert® (250/251), iTec (Tecnis®1) and AutonoMe™ (Clareon®). The evaluation was carried out on a 10-point scale for parameters related to IOL implantation safety when using preloaded systems, convenience and intuitive operation, the level of control over the IOL implantation process, and the overall total time required to complete the entire IOL implantation procedure.Results. Among all the parameters, the experts gave the highest safety rating of the IOL implantation when using preloaded systems; in general, quite high scores were also assigned to the other parameters, reflecting satisfaction with the work by the experts. In a comparative analysis of the parameters of IOL implantation safety, convenience and intuitive operation, the level of control over the IOL implantation process, as well as the total time required for the entire IOL implantation procedure, depending on the type of preloaded systems, significant differences were obtained (p = 0.012, p = 0.001, p = 0.003, p = 0.014, p = 0.004, respectively). Frow the 4 analyzed system types, AutonoMe™ (Clareon®) achieved the highest scores across all dimensions (10.0, 9.0, 10.0, 9.0 and 9.5, respectively).Conclusion. This experts’ survey is the first Russian experience of evaluating the real practice of working with different types of preloaded systems for implanting IOLs. The survey indicated that the greatest application experience currently exists with the preloaded AutonoMe™ (Clareon®) system, which scored higher across all analyzed parameters when compared to systems from other manufacturers.
