Implantation of anterior chamber intraocular lens at II stage in aphakic eye after vitrectomy combined with lensectomy

Objective To investigate and analyze the clinical effect and safety of implantation of anterior chamber intraocular lens at Ⅱ stage after vitrectomy combined with lensectomy.Methods Scleral tunnel incision was made to perform implantation of anterior chamber intraocular lens at Ⅱ stage in 26 aphakic eyes following vitrectomy combined with lensectomy.The patients were followed up with the main observations of best-corrected visual acuity,intraocular pressure,counting of corneal endothelium and the condition of pupils.All patients were followed up for 4 to 28 months,averaging in 15 months.Results Best corrected visual acuity of 0.5 or better was achieved in 26 cases(38.46%).The mean intraocular pressure were 17.2 mmHg(1 kPa=7.5 mmHg;10.9 mmHg to 20.3 mmHg)at last following up.The mean counting of corneal endothelium was 1 621 mm-2(1 163 mm-2 to 2 133 mm-2).The main complications included pupil distortion(4 eyes),hyphema(3 eyes),mild corneal edema(6 eyes),transient elevation of intraocular pressure(1 eye)and iridocyclitis(1 eye).Conclusions For implantation of intraocular lens at Ⅱ stage in aphakic patients after vitrectiomy combined with lensectomy,anterior chamber intraocular lens implantation is a promising selection with good clinical effect and safety.
