Secondary intraocular lens implantation with absence of capsular support: Scleral versus iris fixation

Purpose. - To assess the outcomes of iris fixated (IF) posterior chamber (PC) intraocular tens (IOL) versus scleral-fixated (SF) PC IOL implantation, and compare them with the results reviewed from the literature. Setting. - The study took place in the ophthalmology department of the Eye and Ear Hospital (Lebanon). Design. - This is a retrospective institutional study that collected the records of patients admitted for secondary IOL implantation between January 2007 and December 2016. Methods. - A total of 28 eyes that underwent PC IOL fixation were included, 13 of which underwent trans-scleral PC IOL fixation and 15 of which underwent iris PC IOL fixation. Data were analyzed over a period of 3 years. Results. - Of the 28 patients, 18 (64.3%) were male and 10 (35.7%) were female (mean age at intervention 36.78 +/- 23.47 [standard deviation, SD] years). There were no significant inter-group differences with regard to baseline values and demographic characteristics. Trauma was the most common etiology for posterior capsule insufficiency (82.1%). The mean preoperative baseline BCVA was 0.58 +/- 0.27 logMAR for SF and 0.27 +/- 0.20 logMAR for IF (P= 0.07). Both groups had significant improvement in vision during the follow up period. No significant differences were noted regarding early or late postoperative complications between the two groups. Conclusion. - SF and IF techniques for PC IOL have similar outcomes and result in a significant improvement in BCVA. When compared to AC (anterior chamber) IOL, both techniques seem to yield fewer complications. (C) 2018 Elsevier Masson SAS. All rights reserved.
