Lens dislocation after strabismus surgery.

A case of lens dislocation complicating strabismus surgery is described. This complication following scleral perforation is extremely rare. The lens dislocation occurred in the direction of the connective tissue overlying the perforation site to which multiple cryoapplications had been made. Irrigation and aspiration of the clear lens followed by discission of the lens capsule was necessary because of progressive lens dislocation resulting in profound amblyopia. Accurate aphakic optical correction of the involved eye combined with vigorous occlusion of the fellow eye resulted in excellent visual acuity for both eyes. Cosmetic strabismus surgery was then performed. Continued intermittent occlusion of the fellow eye, combined with continued constant aphakic optical correction of the affected eye will be required. The affected eye will be carefully followed for the long-term complication of retinal detachment associated with connective tissue traction.
