Clinical Trial Summary

On the day of surgery, the the eye with astigmatism of at least 0.75dpt receives a Vivinex XY1A , HOYA Surgical Optics GmbH and the second eye to be operated receives an XY1, HOYA Surgical Optics GmbH.

A complete biomicroscopic examination and visual acuity testing using autorefractometer, will be performed 1 week (7-14days), 6 weeks (30-60days) and 5 month (4-6months) postoperatively.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of FBGC (foreign body giant cells) (slitlamp examination)	The number of foreign body giant cells on the IOLs will be assessed.	5 months
Secondary	Incidence of Monocytes (slitlamp examination)	The number of monocytes on the IOLs will be assessed. The following classification will be used: + = fewer than 10 cells/mm2; ++ = 10 to 25 cells/mm2; +++ = more than 25 cells/mm2	5 months
Secondary	PCO Score (slitlamp examination)	Incidence and development of posterior capsular opacification will be subjectively graded: 0-10 (0= no PCO, 10= maximum PCO)	5 months
Secondary	Grade of Anterior Fibrosis (slitlamp examination)	Grade of anterior fibrosis assessed subjectively at the slitlamp (grade 0=no fibrosis, grade 3=maximum fibrosis)	5 months
Secondary	Anterior chamber reaction (slitlamp examination)	Incidence of cells and tyndall in the anterior chamber (ratet as - to +++ respectively)	5 months
