Clear lens extraction is a refractive surgery used to compensate axial myopia. Formerly, intracapsular lens extraction was performed, but the present surgical method is extracapsular lens extraction or phacoemulsification. Clear lens extraction is becoming controversial because of the danger of complications. We retrospectively reviewed the postoperative complications in 33 eyes of 20 patients who underwent clear lens extraction at other institutions between 1966 and 1984. Twelve patients (60%) had motility disturbances. Eight (24%) of 33 eyes suffered secondary glaucoma; ten (30%), retinal detachment; 12 (36%), lens remnants in the pupillary space; and six (18%), blindness caused by clear lens extraction or by additional surgery performed by us while attempting to improve a poor prognosis. Clear lens extraction appears to be contraindicated in the young, in those with axial diameters greater than 29 mm, and in those presenting with peripheral chorioretinal degeneration. Moreover, clear lens extraction does not avoid the progression of myopia at the posterior segment. We suggest the use of safer, noninvasive, reversible alternatives.
透明晶状体摘除术是一种用于矫正轴性近视的屈光手术。以前采用的是囊内晶状体摘除术，但目前的手术方法是囊外晶状体摘除术或超声乳化术。由于存在并发症的风险，透明晶状体摘除术正变得颇具争议。我们回顾性研究了1966年至1984年间在其他机构接受透明晶状体摘除术的20例患者的33只眼睛的术后并发症。12例患者（60%）出现眼球运动障碍。33只眼中有8只（24%）发生继发性青光眼；10只（30%）发生视网膜脱离；12只（36%）在瞳孔区残留晶状体；6只（18%）因透明晶状体摘除术或我们为改善不良预后而进行的附加手术导致失明。透明晶状体摘除术似乎不适用于年轻人、眼轴直径大于29毫米的患者以及存在周边脉络膜视网膜变性的患者。此外，透明晶状体摘除术并不能避免后段近视的进展。我们建议使用更安全、无创、可逆的替代方法。
