[Surgical treatment of contusive dislocation of the lens]

54 of 60 consecutive cases of contusive lens dislocation (incomplete 45 cases and complete 15 cases) were treated surgically by (1) loop delivery of the lens in 39 cases, (2) double needle fixation (Barraquer's method) in 4 cases, (3) intracapsular cryo- or silicon ball extraction in 5 cases, (4) extracapsular cortical aspiration in 3 cases, and (5) VISC lensectomy and vitrectomy in 3 cases. Surgical treatment is indicated in cases of (1) lens dislocation into the anterior chamber or incarcerated in the pupil; (2) secondary glaucoma induced by pupil block; (3) secondary uveitis; (4) visual impairment due to turbid or eccentric lens; and (5) presence of other complications that require surgical intervention, such as retinal detachment.
