Abstract Details


To compare the incidence of posterior capsule opacification (PCO) and the neodymium:YAG (nd:YAG) laser capsulotomy rates after phacoemulsification with implantation 3-piece, single-piece C haptics and single-piece plate haptics intraocular lens (IOL)


Ophthalmology Department, Hospital dos Lus�Ã�­adas, Lisboa - Portugal


Retrospective study that included patients who underwent phacoemulsification and IOL implantation: 3-piece IOL- ZA9003 (group I), single-piece IOL with C haptics - ZCB00, SN60D3and ZXR00 (group II) and single-piece plate IOL- Tri839MP ATTorbi709/MP (group III). Surgeries and capsulotomies were performed by the same surgeon. The postoperative follow-up period was at least 2 years.We evaluated demographic data (age and gender); IOL data (type and power), PCO incidence, neodymium:YAG laser capsulotomy rates, time elapsed between surgery and PCO detection and time between surgery and Nd:YAG laser capsulotom


An Nd:YAG laser posterior capsulotomy was performed in 382 (26,7%) of the 1429 eyes analysed (18,7% in group I; 21,7% in group II and 60,2% in group III). Mean follow-up was 54 months. Average time between surgery and Nd:YAG laser capsulotomy was 34 months in group I, 27 months in group II and 24 months in group III. Overall, 1 year and 2 years capsulotomy rate was 18,7%, 2,5%, 6,5% with ZA9003; 11,4%, 1,6%, 8,7% with ZCB00; 50%, 0%, 12,5% with SN60D3;18,9%, 5,7%, 18,9% with ZXR00; 60,6%, 8,8%, 35,4%with Tri839MP and 57,1%, 0%, 12,5% with ATTorbi 709MP.


No complications were reported after capsulotomies or IOL opacification, however SN60D3 presented glistening, especially with longer follow up, making capsulotomies more difficult. Capsulotomy rate was higher in the single-piece plate haptics group than in the 3-piece and single-piece C haptic group. Nd:YAG laser capsulotomy was performed later in the 3-piece IOL group.
