title: Comparison of tilt and decentration between phacoemulsification and phacotrabeculectomy.
abstract: OBJECTIVE
  To determine the extent of intraocular lens (IOL) tilt and decentration values after combined surgery in patients with cataract and glaucoma.
  
  
  METHODS
  A total of 106 cataractous eyes undergoing IOL implantation were divided into 2 groups. Group 1 comprised 42 eyes undergoing phacotrabeculectomy surgery for cataract and primary open-angle glaucoma (POAG), and group 2 comprised 64 eyes undergoing phacoemulsification surgery for senile cataract. The length of IOL decentration and the angle of IOL tilt were quantitated by using Purkinje reflections and photographic documentation.
  
  
  RESULTS
  The differences regarding both the IOL tilt (2.84 +/- 0.37; 2.97 +/- 0.37, respectively) and decentration (0.39 +/- 0.27; 0.49 +/- 0.35, respectively) was insignificant (p > 0.05) between groups.
  
  
  CONCLUSIONS
  There is no increased effect of phacotrabeculectomy on tilt and decentration of IOLs in eyes with POAG when compared with eyes which underwent phacoemulsification surgery.
