MICS IOL modification does not affect PCO

Modifying a MICS IOL from a 3-piece to a 1-piece haptic design does not cause any significant changes in PCO amount, according to recently produced data.

A research team led by Dr Birgit Weingessel, Department of Ophthalmology, Hietzing Hospital, Vienna, Austria, studied 80 eyes of 40 patients with age-related cataract.

Each participant received a 1-piece MICS IOL in one eye and a 3-piece MICS IOL in the other. After one year of follow-up patients were assessed using a slit-lamp. High-resolution images were taken to determine PCO amount and visual acuity was measured accordingly.

Mean regeneratory PCO score and the neodymium-yttrium-aluminium-garnet laser capsulotomy rate were significantly low for both IOLs. But capsular folds occurred more often in the eyes that were administered the 3-piece IOL.
