Purpose:To note the incidence of complications of flexible three piece silicone IOL ( Allergan SI 30NB ) in relation to the capsular bag and see if there is any correlation between different age groups . Methods: In this retrospective study , records of 175 patients were reviewed with the criteria that the visual disability was due to age related cataract only and free of any other ocular pathology. All the patients had uncomplicated phacoemulsification by the same surgeon using the same technique over a period of 3 years. In the age group of below 80 years, 53 (48.18%) were between 70–80 years , 42 (38.18 %) were between 60– 70 years and 15 patients (13.63%) were between 55–60 years. In the age group of equal to or over 80 years , 50 ( 77%) were in the range of 80 – 85 years and 15 ( 33% ) were between 86 – 92 years range The follow up ranged from 6 months to 36 months. The IOL induced complications were then statastically analysed by dividing the patients into two different age groups of less than 80 years and more than 80 years using Fisher’s exact test. Results: Capsulorrhexis phimosis , defined as opening of less than 2mm was seen in 5 patients ( 4.54% ) of less than 80 years and in one patient (1.53% ) of more than 80 years . Posterior capsule thickening was seen in 18 patients (16.36%) of less than 80 years and in 6 patients ( 9.23% ) of more than 80 years of age. The complications of silicone intraocular lenses in relation to the capsular bag appear to be lower with increasing age with a statastically significant p value of < 0.05 Conclusions: In our study we found that higher the age group of the patients, better they fared with less number of IOL related complications after implantation of a three piece silicone IOL which could be due to decrease in the reparative ability of the cells and the internal forces related to capsular dynamics.
