- Abstract:
- Purpose: To assess the intraoperative complication risks and the rate of secondary surgical interventions¿ necessity of iris fixated intraocular lens implantation for the correction of refractive errors or aphakia. Material and Methods: Retrospective, single-center data analysis of patients who underwent iris fixated intraocular lens implantation. Data was acquired through the intranet of the Medical University of Graz Eye Clinic and the log books. Data of 327 implantations in 233 patients from 2005 to 2012 was reviewed. Mean follow-up period was 4.30 years, ranging from 0.45 up to 8.39 years. Main outcome measures were intraoperative complications (intraocular haemorrhage, early ocular hypotension, pupil ovalization and decentration, immediate luxation or decentration of the lens, and corneal haze) as well as the rate of needed reoperations for reasons like disenclavation or the need of explantation. Results: Intraoperative complications occurred in 19 out of 327 cases (5.81%). Intraocular haemorrhage occurred 9 times (2.75%), immediate decentration or luxation of the lens 5 times (1.53%), pupil ovalization or decentration 3 times (0.92%), and ocular hypotension and corneal haze 1 time each (0.31%). Secondary surgical intervention was performed after 20 implantations (6.12%), whereas in 4 cases (1.22%) follow-up surgery had to be performed a second time. Reasons for secondary surgical intervention were disenclavation of the lens (22 cases, 6.73%), 1 case of endophthalmitis (0.31%) and 1 case of corneal wound leakage (0.31%) with the necessity of secondary suturing. Conclusion: Iris fixated intraocular lens implantation provides a safe way of treating refractive errors and cases of aphakia without adequate capsular support in terms of intraoperative complications and secondary surgical intervention rate.
