Introduction: Cataract is one of the most common and established surgical procedure in
Opththalmology in the world with the posterior capsular opacification (PCO) as a very
common complication, which may be present in long term. This study was done to find the
incidence of the posterior capsular opacification after cataract surgery and implantation of
360 square edge PMMA posterior chamber IOL among the patients attending our tertiary care
Materials and Methods: The cataract surgery was done with a careful implantation of a
square edged single piece PMMA IOL within the capsular bag seeing that peripheral 1mm of
the anterior capsular rim covers the optic edge of the IOL. On the 1st postoperative day, the
cases were examined under slit lamp for any postoperative complications. The next visits
were conducted at day 7, 1 month, 3 months, 6months and 8 months. The best-corrected
visual acuity was tested using Snellen chart, both aided and unaided.
Results: Out of 50 patients included in the study, 21 (42%) were females and 29 (58%) were
males. The most common age group of all the patients was 61-70 years wherein 58.6% of the
males and 42.9% of the females were present. Of the total 50 eyes operated for cataract, 90%
of the patients had no posterior capsular opacification, while 4% had fibrous membrane type
of PCO and 6% had Elsching’s Pearl type of PCO.
Conclusion: The square edged PMMA IOL is quite effective in reducing the formation of
posterior capsular opacification after the cataract surgery
