The following article was received based on a literature review: article: video analysis of optic-haptic-interaction during hydrophobic acrylic intraocular lens implantation using preloaded injectors an observational, retrospective study was done to compare the optic-haptic interaction of different hydrophobic acrylic intraocular lenses (iols) after using six preloaded injectors.The video-recordings of procedures on a total of 388 eyes (n=388 eyes) that underwent phacoemulsification and intraocular lens (iol) implantation were reviewed.For six preloaded injectors: multisert (hoya surgical optics) [system 1], tecnis simplicity (johnson & johnson vision) [system 2], tecnis itec (johnson & johnson vision) [system 3], autonome (alcon, laboratories) [system 4], bluesert (carl zeiss meditec) [system 5], and prosert (ophthalmopro gmbh) [system 6], the time of iol delivery and observation of iol insertion and optic-haptic-interaction were noted.A centurion (alcon, usa) or whitestar signature (johnson & johnson, usa) phacoemulsification machine were used for the surgeries.Systems 2 and 3 were used in implantation of the tecnis iols (tecnis dib00 and tecnis pcb00).The same ophthalmic viscosurgical device (ovd) (hydroxypropylmethylcellulose [20.0 mg]) at room temperature (20¿23° c) was used in all cases.Events included: deformed delivery behavior: system 2: in the leading haptic (19.5%) and in the trailing haptics (6.1%).System 3: in the leading haptic (14.1%) and in trailing haptics (4%).Adhesions: system 2 (43.9%): adhesion between two haptics (21.9%) and haptic-optic adhesion (21.9%) system 3 (52.5%): between two haptics (22.2%), and between haptic and optic (30.3%) system 2 (28.1%) and system 3 (32.3%) required additional manipulation to release the adhesion and perform rotational adjustments to optimize the iol¿s orientation within the central of the capsular bag.System 3 showed the longest mean delivery time (34.8 ± 9.8).There are no indications in the article of any interventions provided.A copy of the article is attached to this report.A separate report will be submitted for the system 2 lens.
