†The A-constant mentioned above is presented as a guideline only for lens power calculations. It is recommended that the A-constant measurement be customized based on the surgeon‘s experience and measuring equipment.
‡These optimized constants for the calculation of intraocular lens power published by ULIB on their website: http://ocusoft.de/ulib/c1.htm are calculated from 319 clinical results for model 250/251 as of October 31, 2016. These constants are based on actual surgical data and are provided by ULIB as a starting point for individual constant optimizations. The information available on the website is based on data originating from other users and not by HOYA Surgical Optics (HSO). HSO therefore does not warrant the correctness, completeness and currentness of the contents on the said website.

Evaluations included a total of 8 procedures and were graded using the seven-point Likert scale:
ease of preparation (IOL loading for cartridge, OVD injection, advancing into nozzle) and ease of implantation (injector body rotation, nozzle insertion, visibility of IOL haptics and rod in the eye, haptics configuration, IOL delivery).

The priming time for manually loaded IOL delivery systems represents the time needed to load the IOL into the cartridge, inject the OVD and advance the IOL into the nozzle. The priming time for ezSert™ represents the time needed to inject the OVD and advance the IOL into the nozzle (there is no need to load the IOL into the cartridge). The implantation procedure for all three delivery systems represents the time from which the leading haptic exits the nozzle tip, to the time the trailing haptic fully exits the nozzle tip.

A fast approach for your everyday practice
ezSert™ is significantly faster to use than manually loaded IOL delivery systems1
ezSert™ requires just 15.10s to prime. In comparison, two commonly used manually loaded IOL delivery systems require 73.67s and 54.67s, respectively.
79.5% less priming time versus AcrySof® IQ +MONARCH® III + D cartridge (P < 0.01) 72.4% less priming time versus TECNIS® 1-piece (ZCB00) +UNFOLDER® Platinum 1 Series + 1MTEC30
cartridge (P < 0.01)
