[Retropupillary pseudophakia after extracapsular cataract extraction]

Implantation of a retropupillary artificial intraocular lens into the capsule of the lens is from the anatomical aspect the most physiological type of pseudophakia. The authors compare the early results of implantation of two models of retropupillary intraocular lenses, i.e. an intraocular lens made from one piece (PMMA loop) and an intraocular lens with polypropylene loops Intraocular lenses with PMMA loops are more difficult to insert in the capsule, they keep, however, better in position than intraocular lenses with a polypropylene loop. Greater traumatisation of surrounding tissues during implantation of intraocular lenses with a PMMA loop leads to a higher incidence of posterior synechia and deformation of the pupil. The differences between the two groups are statistically significant. No statistical correlation was found when the functional results were compared. The same applies to peroperative and other postoperative complications (uveitis, non-infectious endophthalmitis, sy. of transillumination and dispersion of pigment and CEM. No case of secondary glaucoma, bullous keratopathy or detachment of the retina was recorded. A corrected vision of 5/15 or better was achieved in 97.50%.
