小切口手法碎核治疗小瞳孔硬核白内障

Objective To discuss the effect of new method of nucleus chopping for hard nucleus that over degree Ⅳ in manual small-incision microcoria cataract surgery. Methods All 57 cases(69 eyes)with the hard nucleus of degree Ⅳ-Ⅴ had undergone manual small-incision microcoria cataract surgery with applying intratunnel nucleus chopping method that designed by the author. The vision acuity, astigmatism and complication of postoperative complication had been discussed. Results The visual acuity was ≥ 0.5 in 46 eyes (66.67%), ≥ 0.8 in 14 eyes(20.29%)and <0.25 in 4 eyes(5.80%)one month after operation. After operation cornea astigmatism had none statistics difference(P>0.05)between that of Preoperative. The complications included cornea edema(13.04%), uveitis(13.04%), iris accretion(5.80%), after-cataract(5.80%)and increased tension(2.90%). The complications diminished after symptomatic treatment in one week. Conclusions Scleral-tunnel small incision for hard nucleus in manual small incision microcoria cataract surgery is safe, simple and the less complication. It is virtue of rapid recovery, good outcome and medical expenses.
