The results of clear lens extraction and posterior chamber intraocular lens implantation in 31 eyes with high myopia and six eyes with high hyperopia were reviewed. In the myopic group, 77% of eyes achieved 20/40 or better uncorrected postoperative visual acuity and 97% achieved 20/40 or better corrected acuity. Sixty-eight percent of eyes were within 1.0 diopter (D) of emmetropia and 90% were within 2.0 D. Astigmatic keratotomy (four eyes) and radial keratotomy (one eye) were performed for postoperative refractive errors. Intraocular lens exchange was necessary to correct power in one case. In the hyperopic group, all six eyes achieved 20/40 or better uncorrected postoperative visual acuity and all were within 1.0 D of emmetropia. During the 20-month mean follow-up, no retinal detachment or cystoid macular edema was observed. Posterior capsule opacification was the major complication and it developed faster than reported in other studies.
回顾了31只高度近视眼睛和6只高度远视眼睛的透明晶状体摘除及后房型人工晶状体植入的结果。在近视组中，77%的眼睛术后未矫正视力达到20/40或更好，97%的眼睛矫正视力达到20/40或更好。68%的眼睛屈光不正度数在正视眼1.0屈光度（D）以内，90%在2.0 D以内。对4只眼睛进行了散光性角膜切开术，对1只眼睛进行了放射状角膜切开术以矫正术后屈光不正。有1例需要进行人工晶状体置换以矫正屈光度。在远视组中，所有6只眼睛术后未矫正视力均达到20/40或更好，且所有眼睛的屈光不正度数均在正视眼1.0 D以内。在平均20个月的随访期间，未观察到视网膜脱离或黄斑囊样水肿。后囊膜混浊是主要并发症，其发生速度比其他研究报告的要快。
