摘　　要：目的探讨玻璃体切割联合晶状体切除术后无晶状体眼患者行Ⅱ期前房型人工晶状体植入术的临床疗效和安全性。方法 26例患者均采用巩膜隧道切口行Ⅱ期前房型人工晶状体植入术,术后观察患者视力、眼压、角膜内皮细胞计数和瞳孔状态等情况,随访时间平均为15个月（4~28个月）。结果 26例患者术后最佳矫正视力≥0.5者10眼（38.46%）;术后末次随访眼压平均为17.2mmHg（1kPa=7.5mmHg,10.9~20.3mmHg）;术后末次随访角膜内皮计数为（1163~2133）mm-2,平均为1621mm-2。手术并发症主要有瞳孔变形（4例）、少量前房积血（3例）、角膜轻度水肿（6例）、一过性眼压升高（1例）、虹膜睫状体炎（1例）。结论对于玻璃体切割联合晶状体切除术后无晶状体眼的患者而言,选择Ⅱ期前房型人工晶状体植入安全、有效。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.
