Abstract Details

Purpose:

To examine and report the short and long-term safety and efficacy of posterior chamber scleral fixated intraocular lens (SFIOL) technique in adults.

Setting:

Department of Ophthalmology, Universitary Hospital of Basurto, Bilbao, Spain.

Methods:

We carried out a retrospective analysis of 34 eyes of 34 consecutive adult patients who underwent implantation of posterior chamber lenses with transscleral sutures between January 1995 and March 2013 at the Department of Ophthalmology, Universitary Hospital of Basurto, Bilbao, Spain. The mean age of the patients was 68,7 years (range 24 - 97 years). Twenty eyes (58,82%) were aphakic at the time of surgery. The other 14 (41,18%) were pseudophakic, only one had anterior chamber IOL, and all of these lenses where removed in the same SFIOL implantation surgery.

Results:

100% of procedures were performed without intraoperative complications. The mean follow-up was 73,67 months (range 8 - 195,5 months). The early complications (in the first two postoperative weeks) included one retinal detachment, one transient raise of intraocular pressure (IOP) (correctly treated with topical antihypertensive medications), two cases with hiphema one of them with associated acute glaucoma (correctly solved with medication), and one lens tilted. The long term complications (after two postoperative weeks) included one vitreous hemorrhage associated with retinal detachment, four macular cistoid oedema correctly solved, one macular oedema associated with macular hole, two epirretinal membrane, two pupil capture, two spontaneous IOL dislocation and one tilted lens. Mean best corrected visual acuity (BCVA) in decimal scale units improved significantly from 0,3868 (standard deviation [SD] 0,2783) to 0,6074 (SD 0,3053; P=0,002)). Mean spherical equivalent changed from 5,8462 (SD 7,1422) to -1,8125 (SD 1,9479). At the end of follow-up, BCVA was unchanged or improved in 27 patients (79,42%), reduced by three decimal lines in 4 patients (11,76%) and 3 patients (8,82%) worsened more than three decimal lines.

Conclusions:

The secondary implantation of posterior chamber sutured fixed intraocular lens technique was found to be a reasonably safe and effective procedure in adults. The main advantages of this technique include easy intraoperative suture management with good visual acuities. FINANCIAL INTEREST: NONE
