我院自1987年以来共行后房人工晶体植入术306眼次,其中白内障囊间摘除及囊袋内植入人工晶体30眼次,报导如下:材料与方法男性13眼次,女性17眼次,平均年龄66.47岁。术前均测K 值及超声测定眼轴及所需人工晶体屈光度。人工晶系美国制IO-LAB 及Oculus 21。襻为J、改良C,改良J及C 型,光学部分直径6mm 及7mm。手术方法:术前面神经阻滞麻醉及球后麻醉,气囊压迫眼球降压,缝上、下直肌固定眼球并开睑,作以穹窿部为基底的结膜瓣,双极电烙器止血。角膜轮部上方1mm 作巩膜半层切口,向前剥离至透明角膜内,11点处作前房穿刺。以角膜刀由此穿刺口刺入前 Since 1987, our hospital co-line posterior chamber intraocular lens implantation 306 times, including cataract removal and intraocular lens implantation intraocular lens 30 times, reported as follows: Materials and Methods Male 13 times, 17 female Times, the average age of 66.47 years old. K values ​​were measured before surgery and ultrasound determination of the ocular axis and the required intraocular lens refraction. IOL-made American IO-LAB and Oculus 21.襻 for J, improved C, improved J and C, the optical part of the diameter of 6mm and 7mm. Surgical methods: preoperative nerve block anesthesia and posterior capsule anesthesia, ophthalmic balloon oppression ophthalmic antihypertensive, sewn, the lower rectus fixed eye and open eyelid, for the dome of the conjunctival flap, bipolar electrocauter to stop bleeding. 1mm above the corneal wheel for scleral half incision, stripping forward to the transparent cornea, at 11 o’clock for the anterior chamber puncture. To puncture the corneal knife piercing before this
