Abstract Details


To evaluate changes in the parameters of anterior segment (AS) after cataract surgery and the correlation between these changes and intra ocular pressure (IOP).


Clinical practice, prospective, no comparative study. Barraquer Ophthalmology Center,Barcelona, Spain


Forty-two consecutive cases of Caucasian race were included in the study. Outcome measures were: IOP, anterior chamber depth(ACD),iris curvature (IC), angle opening distance at 500 ┬Ám from the scleral spur (AOD500,),angle recess area (ARA500) and trabecular iris space area (TISA500). The measures were realized before surgery, 2 weeks, and 3 months after surgery.


AOD500 was 0.6 mm and changed to 0, 8 mm and 0,4 at 2 weeks and 3 month respectively. TISA500 was 0.09 mm2 and increased to 0.35mm2 and 0,23mm2 at 2 weeks and 3 month respectively, ARA500 was 0.09 mm2 and increased to 0.38mm2, 0,26mm2 2 weeks and 3 month respectively. IC reduced signeficaly after surgery.The IOP before surgery was 23mmhg and reduced to 19, 18 mmhg during the study.


Parameters of the anterior segment increased at 2 weeks after surgery to reduce slightly again at three month. These changes correlated to IOP lowering.
