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.
