Authors monitored changes of anatomical relationships of the anterior segment of the eye, following after the cataract surgery (standard phacoemulsification with implantation of the posterior chamber intraocular lens). They monitored especially the depth of the anterior chamber and angle width, and further anatomical relationships and configurations of anterior chamber structures. The results show, the cataract surgery may significantly change anatomical relationships and that these changes are advantageous (the anterior chamber goes deeper and the angle more width).
