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
hospital.
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

Background: Cataract is the leading cause of blindness worldwide. Out of them traumatic cataract is a common variant occurring in the spectrum of ocular trauma. It is a significant prerequisite of monocular blindness worldwide. Timely management and early intervention are essential in view of traumatic cataract. Different types of lenses such as anterior chamber intraocular lens and posterior chamber intraocular lens, scleral fixated intraocular lens can be used in the management of traumatic cataract. This study will be conducted to find out the correlation between different types of intraocular lenses used in cataract surgery and their potential role in the visual outcome of the patient and meanwhile considering factors such as type of trauma, amount of time interval between trauma and surgery, preoperative and postoperative complications etc. 
Objectives:
1.To know modes of presentation and different injuries causing traumatic cataract.
2.To assess the visual outcome of the patients post traumatic cataract surgery using different types of intraocular lenses.
3. To study the complications occurring in patients undergoing traumatic cataract surgery.
Methods: This study will be conducted in Acharya Vinoba Bhave Hospital, Sawangi (Meghe) associated to Datta Meghe institute of Medical sciences, Wardha, it will be a hospital based Interventional Cross sectional study with a sample size of 40 patients. Clinical history will be taken and Comprehensive ophthalmic examination, including best corrected visual acuity (Snellens chart), slit lamp, IOP measurement (applanation tonometer) and fundoscopy (slit lamp biomicroscopy with 90 D, indirect and direct ophthalmoscopy) and B- scan, IOL power calculation by SRK-T formula will be performed. Following which the patients will under undergo cataract extraction with intraocular lens implantation. Final visual outcome will be assessed by the end of 6 weeks. 3 follow ups will be there after first day, first week and sixth week.
Expected Results: The main objective of this study will be to assess the improvement in visual outcome of each of the 40 patients suffering from traumatic cataract by the use of different types of intraocular lenses depending upon the situation they present in. Studies conducted in the past have shown a considerable improvement in the visual outcome of the patients with the use of different types of intraocular lenses.
