System U had the least corneal incision enlargement (mean 0.07 mm ± 0.05 ) and the smallest final incision size (mean 2.31 ± 0.06 mm) (P <. Statistical analysis was performed to determine the significance of differences between groups.Īll systems successfully placed the IOL in the capsular bag. The rate of successful in-the-bag IOL delivery, IOL adherence to the plunger tip, trapped trailing haptic, and presence of nozzle tip splitting were assessed. Corneal incision size was measured before and after delivery. To compare the delivery performance of a new preloaded intraocular lens (IOL) delivery system (Ultrasert ) with that of 2 commercially available preloaded systems (iSert and Tecnis iTec ), and a manual system (Monarch III D).Īlcon Laboratories, Fort Worth, Texas, USA.įreshly excised porcine eyes were randomly assigned to 5 groups of 10 eyes each as follows: preloaded systems U, S, T 2.2 mm incision, T 2.4 mm incision, and manual system. Further studies are needed to assess the possible effects of those superficial damages on the optical quality of the IOLs. After folding and injection process some superficial scratches and tears of the IOL optic were detected in some models. In other cases, small superficial tears were seen in a more peripheral position.Īll lenses showed excellent surface quality. Some IOLs showed superficial scratches and tears on the optic surface, mainly positioned according to the direction of the stress induced by the folding process. After rinsing and metallization process, scanning electron microscopy images were acquired.Īll IOLs presented high-quality construction biomaterials. IOLs were injected through a dedicated 2.2-mm MICS cartridge into a 50-mL vial containing 10 mL of deionized water. Twenty intraocular lenses of each type were studied: ten with a power of + 21 D ± 1 and ten with a power of + 28 D ± 1. In this experimental laboratory study, the following IOLs were studied: Johnson&Johnson PCB00, HOYA iSert 251, Alcon AcrySof IQ SN60WF, Bausch&Lomb enVISTA MX-60. 125000001424 substituent group Chemical group 0.To evaluate possible surface alterations of different models of one-piece foldable acrylic intraocular lenses (IOLs) after folding and ejecting process through 2.2-mm microincisional cataract surgery (MICS) cartridges.239000011796 hollow space material Substances 0.000 claims abstract description 14.238000006460 hydrolysis reaction Methods 0.000 claims abstract description 20.230000002708 enhancing Effects 0.000 claims abstract description 74.238000003780 insertion Methods 0.000 title claims abstract description 32.Status Active legal-status Critical Current Anticipated expiration legal-status Critical Links CHANGE OF NAME (SEE DOCUMENT FOR DETAILS). reassignment Johnson & Johnson Surgical Vision, Inc.
