A case of decentered IOL managed with optic buttonholing.

We describe an unusual case which presented with late lateral IOL decentration secondary to bag subluxation in the presence of a posterior capsular defect. Instead of approaching the case with the usual IOL exchange with iris-fixated or anterior chamber IOL or by fixating it to the sclera, a relatively non-invasive sutureless method of IOL re-centration was performed by buttonholing the optic into the posterior capsular defect. It enabled a perfect IOL centration with minimal incidence of astigmatism, inflammation, macular edema, secondary glaucoma, or corneal decompensation.
