PURPOSE To evaluate the efficacy and safety of coreoplasty and an iris-supported Artisan intraocular lens (IOL) implantation for mydriasis and aphakic correction in post-traumatic vitrectomized eyes.
METHODS 17 cases of aphakic patients were observed during April 2009 and April 2010. All eyes had lens removed and vitrectomized previously. After the retina stable and corrected visual acuity improved, iris was sutured and artisan IOL was fixated in iris surface. Patients were followed for symptom of photophobia and glare, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), intraocular pressure (IOP), endothelial cell density (ECD). The diameter of pupil and the anterior chamber depth (ACD) were calculated by the segment anterior OCT preoperatively and postoperatively.
RESULTS Artisan IOLs were successful implanted in all aphakic eyes. Patients postoperative follow-up was 3--12 months. The symptom of photophobia and glare improved postoperatively. UCVA improved in all patients (six eyes get better UCVA postoperatively than BCVA preoperatively).However there were no significant changes in IOP. Mean loss of ECD was 336.06/mm2.Mean postoperative pupil diameter was 3.67±0.41mm, whereas it was 5.67±0.57mm preoperatively (P<0.05).Mean ACD reduced by 0.88mm (3.38±0.33mm preoperatively vs 2.50±0.35mm postoperatively<0.05).
CONCLUSION Coreoplasty and artisan IOL implantation were a safe and effective procedure to correct aphakia and mydriasis in post-traumatic vitrectomized eyes. Considering good visual rehabilitation, improvement of photophobia, less injury and low rate of complications, this procedure is recommended in vitrectomized eyes with iris supported.
