Clinical application of knotless scleral-fixated posterior chamber intraocular lens

AIM:To evaluate the safety and stability of knotless scleral-fixated posterior chamber intraocular lens(PCIOL).<p>METHODS:Thirty-nine eyes of 35 patients with dislocation of lens, capsule broken after cataract extraction or aphakic eyes after vitrectomy were retrospectively analyzed. They were undergone knotless scleral-fixated PCIOL without scleral flap from January 2009 to October 2014 at He Eye Hospital in Shenyang. Pre-operative and postoperative best-corrected visual acuity(BCVA), intraocular pressure(IOP), the stability of intraocular lens and complications were observed and analyzed.<p>RESULTS:The BCVA of 9 eyes(23.1%)were 0.1≤BCVA<0.3, 20(51.3%)eyes were 0.3≤BCVA<0.5, 6 eyes(15.4%)were 0.5≤BCVA<0.8, and 4 eyes(10.3%)were 0.8≤BCVA<1.0 at 3mo postoperatively. Two eyes had mild iridemia intraoperatively, which were absorbed in 2wk. Three eyes had transient ocular hypertension, and three eyes had cornea edema postoperatively, all of them were cured through drug treatment in a week. There had no corneal decompensation, ciliary detachment, retinal detachment and endophthalmitis on any patient. The mean follow-up time was 24(3～60)mo. There was no complications of IOL tilting/dislocation, suture exposure, scleral attenuation or scleral dissolution postoperatively. <p>CONCLUSION:The knotless scleral-fixated PCIOL is a safe and effective technique for aphakic eyes with deficient posterior capsular support, which reduces postoperative suture related complications
