Abstract

We experienced 20 patient's 21 eyes of lens displacement including subluxation(16 eyes) and luxation(5 eyes) which were surgically treated by two methods; trans-scleral fixation(14 eyes) and pars plana approach(7 eyes). The causes of lens displacement were trauma(10 eyes), unknown or spontaneous(6 eyes), congenital(2 eyes) and iatrogenic(3 eyes). All patients were male, except 2 female and aging from 11 to 75 years(mean 48.4 years). Post-operative vision showed varying degrees of improvement although 3 showed no change and 1 eye was enucleated for accompanying disorders. Increased intraocular pressures were noticed in 13/21(61.9%) eyes preoperatively, but 3/12(25%) eyes excluding 1 enucleated eye remained high postoperatively, meaning that the intraocular pressure can be normalized by the removal of lens itself. We concluded that these two methods would be adequate modalities for the management of displaced lens, and these two methods share some benifit/drawback over each other. In case of hard nucleus, the pars plana technique must be done very carefully because the fallen, whirling nuclear debris might damage the posterior pole. It may be necessary to switch to the transfixation mehtod.
