Abstract Details


To evaluate the role of posterior capsular opacifications (PCO) and YAG capsulotomy on intraocular aberrations in monofocal psuedophakic patients.


Department of Ophthalmology, Poznan City Hospital, PoznaƄ, Poland.


Studied group consisted of 60 consecutive monofocal pseudophakic patients (eyes) with PCO prepared for YAG procedure. Intraocular aberrations were measured in mydriasis before and after the procedure with KR1W Topcon. Corneal, the lenticular and total astigmatism as well as total ocular aberrations (HOA) were analyzed. Each YAG capsulotomy was based on circular pattern and standard power settings between 1.5- 3.0 mJ, with the total energy for each procedure between 30-70 mJ.


In 30% of eyes it was not possible to measure before capsulotomy the internal astigmatism and HOA. After the YAG capsulotomy corneal and ocular astigmatism were not changed, whereas internal astigmatism decreased significantly (P = 0.022). Although corneal HOA did not change, the total ocular HOA decreased on average by 0,232 dioptres (P < 0.001) and total internal HOA decreased a decrease on average by 0.226 dioptres (P = 0.024).


YAG capsulotomy leads to a decrease in internal astigmatism (lenticular) and total internal and total ocular HOA, what improve probably significantly the quality of vision.
