Abstract Details

Purpose:

To evaluate indications and clinical efficacy of intraocular lens (IOL) explantation procedures in 3-year period at Department of Ophthalmology at Clinical Hospital Center Rijeka, Croatia.

Setting:

Our retrospective study included all rare cases with IOL explantation which had been performed at our institution between March 2010 and March 2013.The study included cases of 14 eyes from 14 patients treated with IOL explantation with or without IOL implantation.

Methods:

Subjects included were 9 men (64%) and 4 women (36%). The time interval between initial IOL implantation and then IOL explantation was 2 to 60 months (mean time 14 months). All explantation surgeries were managed by cataract surgeon through a limbal incision. Explantation was primary in 3 eyes and secondary in 11 eyes. Indications for IOL removal were: IOL subluxation/dislocation in 6 eyes, corneal decompensation with/without reccurent inflammation in 4 eyes, IOL damage in 3 eyes and incorrect IOL power in 1 eye. IOL was removed 'flat' thru 5-6 mm incision or by bisecting the optics thru 3 mm incision.

Results:

Treatment after explantation was: aphakia in 43% of eyes, reimplantation in 57% of eyes: posterior chamber IOL implantation in 5 eyes (36%), anterior chamber IOL implantation in 3 eyes (21%). Postoperative best corrected visual acuity (BCVA) was better or equal to preoperative in 8 eyes (57%). Intraoperative complications were: need for anterior vitrectomy in 5 eyes (36 %), zonular dehiscence in 1 eye (7%),1 iris bleeding (7%), retained haptics in 1 eye (7%).

Conclusions:

There have been a few clinical reports regarding the phenomenon of need for IOL explantation. Decentration-dislocation and incorrect lens power, glare and optical aberrations are leading indications for IOL explantation. IOL exchange is a technically challenging procedure and postoperative visual acuity results are dependent on the preoperative complications. FINANCIAL DISCLOUSRE: NONE
