Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Purpose: To compare the posterior capsule opacification (PCO) inhibiting effect of the sharp posterior optic edge design of the Clariflex silicone intraocular lens (IOL) with that of the double-round edge design of the SI40 (Phacoflex) silicone IOL over a period of 3 years.

Setting: Department of Ophthalmology, Medical University of Vienna, Vienna, Austria.

Methods: Fifty-two patients with bilateral age-related cataract (104 eyes) were included in this randomized, prospective, bilateral, patient- and examiner-masked clinical trial with intra-individual comparison. Each study patient had cataract surgery in both eyes and received an SI40 IOL (anterior and posterior round optic edges) in one eye and a Clariflex IOL with OptiEdge (round anterior and sharp posterior optic edge) in the other eye. Follow-up examinations were at one week, one month, six months, one, two, and three years. Digital retroillumination images were taken of each eye. The amount of PCO was assessed subjectively at the slit-lamp and objectively using automated image analysis software (AQUA) one, two, and three years after surgery.
