The visual outcome and surgical complications in posterior capsular rupture following cataract surgery with scleral fixated intraocular lens in tertiary care centre – A prospective study

Abstract

Aim: To analyse the complications as well as the long term functional and visual outcomes of anterior vitrectomy with scleral fixated posterior chamber intraocular lens implantation in patients with inadequate posterior capsular support. Settings and Design: This was a prospective study done at Coimbatore Medical College Hospital, Coimbatore during the period of May 2016 to December 2017. Materials and Methods: 30 eyes of 25 aphakic patients and 5 patients who had primary scleral fixated IOL implantation were included in the study. Anterior segment examination with slit lamp, preoperative visual acuity, intraocular pressure, fundus examination and IOL power calculation was done. Results: Scleral fixation of IOL is a safe procedure with a success rate of 93% and most of the intraoperative and postoperative complications were minor. Postoperative best corrected visual acuity of 6/12 and above was seen in 70% of patients. Conclusion: Anterior vitrectomy with scleral fixated IOL implantation is a safe and effective procedure to correct aphakia in eyes without adequate posterior capsular support. Complications seen with anterior chamber IOL are not seen with SFIOL and dreaded complications like retinal detachment, suture lysis and infection were not encountered in our study. However precise determination of small differences in visual outcome and long-term complication rates would require a large prospective, randomized clinical trial.
