Implantation of scleral-fixated posterior chamber intraocular lenses in adults.
OBJECTIVE
To report the results of transscleral fixation of posterior chamber intraocular lenses in adults.


METHODS
We carried out a retrospective analysis of 91 eyes of 81 patients who underwent implantation of posterior chamber lenses with transscleral sutures between 1997 and 2006. The mean age of the patients was 62 years (range 19-94 years). Sixty-eight eyes (74.7%) were aphakic at the time of surgery. In 10 patients (11.0%) an intracapsular cataract extraction and in six patients (6.6%) a pars plana lensectomy was performed prior to the fixation of the posterior chamber intraocular lens. In seven eyes (7.7%) a previously implanted IOL was removed. The mean follow-up was 36 months (range 6-116 months).


RESULTS
The mean preoperative best corrected visual acuity (BCVA) was 0.37 (range counting fingers to 1.0), which improved to 0.5 (range light perception to 1.0) postoperatively. At the end of follow-up, BCVA was unchanged or improved in 81 eyes (89.0%), reduced by 2 Snellen lines in four eyes (4.4%), and between finger counting and light perception in four eyes (4.4%). The most serious complication was suprachoroidal haemorrhage, which occurred in two eyes. Retinal detachment occurred in three eyes, all of which successfully reattached after surgery. Suture erosion or spontaneous dislocation caused by suture degradation or breakage was not seen.


CONCLUSIONS
Secondary implantation of posterior chamber intraocular lenses with transscleral fixation is a reasonably safe procedure in adults, with relatively few serious complications. Even in patients with longterm follow-up, suture breakage was not seen.
