Abstract Details


The posterior opacification of the capsular bag after uneventful cataract surgery is a main concern dealing with patients operated for cataract. Our paper evaluates the Posterior Capsule Opacification (PCO) and YAG rates and post-cataract occurrence time of YAG laser treatment for several Posterior Chamber (PC) IOLs (spheric and aspheric, hydrophilic and hydrophobic) implanted at the end of uncomplicated cataract surgeries in our clinic (in eyes operated during 2012 and 2013), in order to be able to establish which is the best IOL design and material available from PCO rate point of view.


Oculus Eye Clinic, Bucharest, Romania


This is a retrospective study which comprises 3287 eyes operated for cataract with the implantation of a PC IOL (spheric and aspheric, hydrophilic and hydrophobic) during 2012 and 2013 with a follow up period of 2-4 years. We formed a data base with the information found in the patients’ files to be able to calculate the PCO and YAG rates and post-cataract occurrence time of YAG laser treatment for all PC IOLs implanted. We also followed all the ocular and nonocular concurent pathology and calculated statistical correlations between these pathologies and PCO rate of occurence.


In 2012 and 2013 we implanted 3287 IOLs of which: 2005 (61%) aspherical, 1282 (39%) spherical, 1500 ( 45,4%) hydrophilic and 1787 (54,6%) hydrophobic. We encountered a very low PCO rate for EnVista (MX60) 1,1% (n= 82) occured in average at 39,9 months postoperatively followed by AcrySof IQ 2,4% rate(n=746) at 21,5 months postoperatively in average and the highest PCO rate for MI60 21%( n=530) at 21.8 months postoperatively followed by Adapt AO 13,2%(n=136) at 22,7 months. The lowest YAG rates were 0% for EnVista and 0,8% for SN60WF and the highest 16,4% for MI60 and 8,1% for AdaptAO.


IOL design and material are the main characteristics influencing PCO and Nd-Yag rates. The EnVista step-vaulted haptics that are designed to vault the optic posteriorly for direct contact with the capsular bag and the 360° square barrier edge gives this lens the lowest PCO rate from our statistics. For the AcrySof® IOL, besides the square edge design, another feature is the material which exhibits great fibronectin binding increasing adhesion to the capsular bag and lowering lens epithelial cell migration. Patient concurrent pathology does not seem to influence the PCO rate, but larger cohorts are needed to confirm these data.
