ABSTRACT
PURPOSE: The aim of the study was to evaluate the state of anterior eye segment in postoperative period after PC-IOL transscleral fixation. MATERIAL AND METHODS: The material comprised 31 eyes in 31 patients, (11 women and 20 men), aged 20-80 years (average 61 years), who underwent the primary or secondary PC-IOL implantation with transscleral fixation. The examination was performed 10 to 14 months (average 12 months) after surgery. The clinical state of the corneas was evaluated using endothelial and confocal microscopy. The position of the IOL, its location and symmetry were evaluated with ultrasound biomicroscopy. RESULTS: The visual acuity ranged from 0.1 to 1.0. In 20 eyes (64%) the position of PC-IOL was correct. In the rest of cases the inappropriate position of implants was observed. The decrease of endothelial cells density was 13% in eyes with primary implantation and 7% in cases with secondary implantation of IOL. In the corneal endothelium, there were features of pleomorfism and polymegatism; in a few cases some deposits were observed. CONCLUSION: The implantation of posterior chamber intraocular lenses with transscleral fixation is recommended for some cases of primary or secondary problems with capsule support. The PC-IOL implantation with transscleral fixation can be the alternative method for the anterior IOL implantation.

The aim of the study is to evaluate results of mean deviation of retinal sensitivity obtained in static perimetry threshold test in glaucoma simplex eyes and to compare them with some biomorphometric parameters of the optic disc measured with scanning laser ophthalmoscope. The analysis was performed with the results obtained in 50 glaucomatous eyes with the disease lasting 4 to 15 years. The mean values of mean deviation, cup to disc ratio, mean cup depth and neuroretinal rim area were 6.71, 0.459, 0.031 and 1.464, respectively. The best correlation coefficient value (0.847) was found between mean deviation and neuroretinal rim area. The results confirm the importance of neuroretinal rim area value in evaluation of optic disc in glaucoma cases.
