All patients were informed about the characteristics of the study and signed the informed consent. Additionally, the protocol was reviewed and approved by the Ethics Committees of the respective centers, and the study followed the recommendations of Good Clinical Practice and the principles of the Declaration of Helsinki. This was a prospective observational study conducted in France (3 sites) and Spain (2 sites) under a protocol approved by a Medicinal Research Ethics Committee (Comité Ético de Investigación Clínica) and in compliance with local regulatory bodies (Commission Nationale de l’Informatique et des Libertés). 13 Overall, System U caused less widening of the corneal incision compared with System M and with other preloaded systems, leading to less surgically induced astigmatism. Compared with manually loaded devices, such as the Monarch ® D Cartridge (Alcon Laboratories) system (System M), use of System U led to a smaller final corneal incision size after IOL implantation. The TensionGlide spring was designed to provide a smooth, consistent, and controlled delivery of the IOL in the capsular bag. The depth guard was designed to help surgeons control insertion depth it is intended to provide a counterforce during insertion, minimize the stretch of the incision, and preserve incision architecture. Unlike other delivery systems, System U has a depth guard and a plunger with a TensionGlide TM system. This single-use system, consisting of a nozzle, main body, and plunger, has been designed so that the preloaded IOL is delivered by manually advancing the plunger using a one-handed push mechanism. The UltraSert TM Preloaded Delivery System (System U Alcon Laboratories, Inc., Fort Worth, TX, USA) has been developed for use with the AcrySof ® IQ IOL (Alcon Laboratories) to provide control and reliability, to reduce complications, and improve time efficiency during cataract surgery ( Figure 1). 6, 7, 17 Recently, comparison studies of preloaded and manually loaded IOL delivery systems showed that preloaded systems resulted in fewer surgical delays and reduced total case time. 12–16 However, the use of preloaded systems may also decrease surgical time. 10, 11 Most studies of preloaded versus manual IOL delivery systems have focused on performance, safety, and postoperative results. 8, 9 Preloaded delivery systems also limit the risk of infection caused by manual handling of the IOL and lead to fewer surgical errors. Minimal incision enlargement reduces the risk of surgically induced astigmatism or corneal wound damage. 6, 7 IOL delivery systems have been designed to facilitate implantation of the IOL through microincisions. 5ĭevelopment of new IOL delivery systems may improve surgical time efficiencies. ![]() 5 Increased labor time was associated with an increase in total costs, with each additional hour of labor time leading to an estimated 10% increase in cost. Economic studies in Europe have shown that direct labor contributed from 17% (Denmark) to 58% (Netherlands) of the total cost, whereas overhead costs contributed from 6% (Hungary) to 47% (England). 3 However, the cost of cataract surgery varies globally, 4 and the specific factors that contribute to the economic burden of cataract surgery vary regionally. 2 Cataract surgery to remove the opaque lens (ie, phacoemulsification) followed by the implantation of an intraocular lens (IOL) is an effective treatment to restore and maintain vision. 1 In 2015, cataract was the most common cause of blindness in Central, Eastern, and Western Europe (25%, 21%, and 21%, respectively), and these rates were projected to remain similarly high in 2020. Cataract has been reported to cause 33% of visual impairment cases and 51% of blindness cases worldwide. ![]()
