Anterior intraocular lens dislocation after combined cataract extraction trabeculectomy.
OBJECTIVE
To evaluate the incidence, cause, and effect of intraocular lens (IOL) dislocation after combined cataract extraction and trabeculectomy.


METHODS
An ophthalmic ambulatory surgery center in Lynwood, California.


METHODS
This retrospective study comprised 150 patients with open-angle glaucoma who had either planned extracapsular cataract extraction (ECCE) (n = 96) or phacoemulsification (n = 54) combined with IOL implantation and trabeculectomy. I reviewed type of cataract extraction, preoperative glaucoma medications, axial length, and amount of filtration achieved postoperatively.


RESULTS
The lens dislocated in 20 eyes (13.3%), with the highest incidence after planned ECCE (18.7%) and the lowest after phacoemulsification with capsulorhexis (3.7%). Eighteen of 30 eyes (60%) that had excessive filtration also had IOL dislocation. Mean induced postoperative myopia in eyes with lens dislocation was-2.25 diopters (D) +/- 0.55 (SD).


CONCLUSIONS
Anterior IOL dislocation was related to increased postoperative filtration and was more common after planned ECCE. In all cases, it caused a distorted pupil, posterior synechias, and induced myopia of over -1.00 D.
