To evaluate the changes in intraocular pressure after surgical correction of late in the bag IOL dislocation.

Retrospective (2005-2014) interventional case series including cases of late spontaneous in-the-bag IOL dislocation from two referral centers. The main outcome measure was preoperative/postoperative intraocular pressure and type of surgery.

149 cases of surgeries to correct in-the-bag IOL dislocation were identified. Dislocation was corrected: 1) repositioning using scleral fixated IOL (SFIOL) (73 cases) or iris suturing (1 case); 2) IOL exchange for angle supported IOL (ACIOL) (38 cases) or iris claw IOL (ICIOL) (30 cases); 3) IOL removal (4 case); 4) capsulotomy (3 cases). Mean IOP decreased significantly after surgery from 20.78±8.3 to 16.27±4.4 in the whole group (p=0.0001). Mean pre and postoperative intraocular pressure was 21.9±9 and 16.6 ±4 (p=0.0001), 19.1±4 and 15.7±4.5 (p=0.0001), 19.5±8.8 and 16.5±5.5 (p=0.0001) mmHG in SFIOL, ACIOL and ICIOL groups respectively.

A significant trend towards a decrease in intraocular pressure was found after the surgical management of in the bag dislocated IOLs. This decrease was independent of the technique used to correct the dislocation.
