Foldable toric IOL safe and effective in high astigmatism

September 12, 2006

According to Omid Kermani from the Augenabteilung der PAN-Klinik am Neumarkt, Köln, Germany, and colleagues, the implantation of a foldable toric intraocular lens (IOL) is a safe and predictable procedure for the correction of high pre-existing corneal astigmatism in cataract surgery.

According to Omid Kermani from the Augenabteilung der PAN-Klinik am Neumarkt, Köln, Germany, and colleagues, the implantation of a foldable toric intraocular lens (IOL) is a safe and predictable procedure for the correction of high pre-existing corneal astigmatism in cataract surgery.

A total of 58 eyes were implanted with the MS 6116 TU IOL (HumanOptics) lens during a retrospective study. The IOL has a 6 mm silicon optic with a toric rear surface and the PMMA-haptics are undulated with a Z-shaped design to prevent secondary rotation. Average preoperative astigmatism was 3.75 D.

Postoperatively, astigmatism was reduced to 0.84 D and surgically induced astigmatism was less than 0.5 D in all cases. 85% of the IOLs remained stable within 10° of the target axis. In 5% of the eyes, secondary rotation was performed three to six weeks postoperatively.

Kermani and his colleagues concluded that implantation of HumanOptics' foldable toric IOL is both safe and effective in treating high corneal astigmatism in cataract surgery.
