STUDY OF VISUAL OUTCOME AND POSTOPERATIVE COMPLICATIONS IN SCLERAL FIXATED POSTERIOR CHAMBER INTRAOCULAR LENS IMPLANTATION
Author: Sangeetha T., Narendra P. Datti
Purpose: To assess the visual outcome and complications in patients after scleral fixated posterior chamber intraocular lens implantation. Materials and methods: This hospital based prospective study was conducted at R.L. Jalappa Hospital and Research Centre, Tamaka, Kolarbetween November 2011 and May 2013. Study included 50 patients fulfilling inclusion criteria. All cases were worked up according to the protocol.Andall patients underwent mandatory anterior vitrectomy followed by Ab –externo scleral fixated posterior chamber intraocular lens implantation.10-0 Proline sutures were used for transscleral fixation of lens haptics. Patients were followed up at 1st day, 1st week, 1st month, 3rd month and 6th month. Postoperative evaluation included best corrected visual acuity, Slit lamp Biomicroscopy and Indirect ophthalmoscopic evaluation and Biomicroscopic assessment of macula. Results: Best corrected visual acuity improved in 28 (56%) patients in the range 6/6-6/12 while 18(36%) patients in the range 6/18-6/36. The most common complication observed were striaekeratopathy, iritis and secondary glaucoma; which subsided by two weeks with postoperative medications. Conclusion: Ab–Externo scleral fixated posterior chamber intraocular lens was found to have stable implantation and a true posterior chamber location in eyes having no capsular or zonular support with a low intra and post-operative risk profile. This technique also showed favourable postoperative visual outcome in aphakic eyes.
