[Comparative evaluation of visual acuity after cataract extraction with monofocal, bifocal or progressive lenses implantation]. / Ocena porównawcza ostrosci wzroku po operacji zacmy z wszczepem soczewek tylnokomorowych jednoogniskowych, dwuogniskowych i progresywnych.

PURPOSE: Evaluation which of the lenses: monofocal, bifocal or progressive, assure the best visual acuity in patients. MATERIAL AND METHODS: 86 patients aged from 21 to 84 years were operated. Monofocal lenses were implanted in 30 cases, bifocal in 32 and progressive in 24 cases. RESULTS: In 90% of patients with monofocal lenses and over 90% of patients in the remaining groups full uncorrected or corrected distance visual acuity was achieved. In groups with bifocal and progressive lenses full near visual acuity without correction, or with the same correction as for distance, was achieved by respectively 65.5% and 75% of patients. CONCLUSIONS: In all three groups very good distance visual acuity was achieved. The best near visual acuity is assured by progressive lenses, in lower degree by bifocal lenses.

[Evaluation of endothelial cells after the usage of gentamycin in irrigation-aspiration fluid during extracapsular cataract extraction]. / Ocena komórek sródblonka rogówki po zastosowaniu gentamycyny w plynie irygacyjno-aspiracyjnym podczas zewnatrztorebkowego usuniecia zacmy.

PURPOSE: Assessment of the density of endothelial cells after usage of gentamicin in irrigation-aspiration fluid. MATERIAL AND METHODS: 60 patients subjected to extracapsular cataract extraction with intraocular lens implantation. In 30 eyes irrigation was performed with Ringer fluid (group I) and in 30 eyes Ringer fluid with gentamicin (group II) 4 mg gentamicin were added to 500 ml of Ringer fluid obtaining the concentration 8 micrograms/ml. Evaluation of endothelial cells density was carried before operation, 1 month and 6 months after. RESULTS: Percentage endothelial cells loss in group I was 7.8% 1 month postoperatively and 14.5% 6 months after operation and in group II 8.5% and 14.87%, respectively. CONCLUSION: Gentamicin added to irrigation-aspiration fluid doesn't cause enhanced endothelial cells loss during extracapsular cataract extraction.

[Comparative evaluation of corneal endothelial cells after extracapsular cataract extraction with PMMA and heparin-surface modified lens implantation]. / Ocena porównawcza komórek sródblonka rogówki po zewnatrztorebkowym usunieciu zacmy z wszczepem soczewek z PMMA i heparynizowanych.

PURPOSE: Comparison of endothelial cells density in eyes after PMMA and heparin-surface-modified lenses (HSfM1) implantation. MATERIAL AND METHODS: 58 patients (26 male and 32 female) aged from 36 to 89 years. In 30 patients PMMA lenses produced by Pharmacia, Storz and Alcon and in 28 HSM (Pharmacia) lenses were implanted, after ECCE. RESULTS: Percentage loss of endothelial cells in eyes with PMMA lenses was 8.61% after month and 13.56% 6 months post-operatively. In eyes with HSM lenses endothelial cell loss was 8.44% and 13.55% respectively. CONCLUSION: Loss of corneal endothelial cells in eyes with PMMA lenses is almost the same in eyes with HSM lenses.

[The effect of selenium and vitamin E on the healing process of experimental corneal lesions in the eye of the rabbit]. / Wplyw selenu i witaminy E na gojenie doswiadczalnego uszkodzenia rogówki w oku królika.

PURPOSE: Evaluation of antioxidants: selenium and vitamin E efficacy in the treatment of experimental corneal lesion. MATERIAL AND METHODS: Solution of selenium in 0.9% NaCl, concentration 0.01 g/L, to which vitamin E was added to obtain suspension of 2.5 g/L was used in 9 rabbits. The cornea was damaged by removing the epithelium from the central area of 7 mm diameter. To the right eye selenium solution with vitamin E was instilled. RESULTS: In two eyes in which antioxidants were used evident prompt healing of corneal ulceration was noticed. Mean lesion diameter in eyes treated with antioxidants was: on 1st day 5.44 mm, in 2nd day 1.61 mm and on the 3rd day 0.33 mm. In control eyes diameters were: 6.67 mm, 2.28 mm and 0.56 mm, respectively. CONCLUSIONS: Solution used in our study was tolerated very well. Faster healing process was noticed in eyes where antioxidants were used.

[Critical evaluation of the treatment of diabetic retinopathy based on personal experience]. / Krytyczna ocena leczenia retinopatii cukrzycowej w oparciu o material wlasny.

The authors present the results of analysis of the treatment of 184 patients (360 eyes) with diabetic retinopathy; it comprises as well the out-patients as the in-patients divided into 4 groups in dependence on the changes and the treatment applied (laser focused photocoagulation, panretinal photocoagulation, cryopexy) the majority of patients reported to the hospital with an advanced proliferative diabetic retinopathy and this allowed only the performance of a panretinal photocoagulation and in a part of cases only cryopexy. The attention is called to the necessity of an early detection of pathological changes and of an early treatment.

[Gentamicin kinetics in the blood and aqueous humor of the rabbit eye after intramuscular and subconjunctival administration]. / Kinetyka gentamycyny w krwi i cieczy wodnistej oka królika podanej domiesniowo i podspojówkowo.

Investigations were performed in rabbits which were given gentamycin intramuscularly and subconjunctivally. After subconjunctival application gentamycin passes quickly into the eye and its therapeutical level persists up to 1 hour. After intramuscular injection gentamycin is passing slower into the aqueous but persists there longer (the therapeutical level--up to 5.5 hours).

[Effect of preoperative intraocular pressure on the course of cataract extraction]. / Wplyw przedoperacyjnego cisnienia wewnatrzgalkowego na przebieg usuniecia zacmy.

The connection between the values of the intraocular pressure before cataract surgery and the number of intraoperative complications was checked. It was established that the preoperative hypotony improves in an essential manner the operative conditions and influences favourably the decrease of the number of complications in the course the surgery. It was confirmed that the manual massage of the eye is equally efficient and less influencing generally the patient than the pharmaceutical lowering of the IOP.

[Intraocular pressure after cataract extraction with implantation of intraocular lenses]. / Cisnienie wewnatrzgalkowe po operacji zacmy z wszczepieniem sztucznej soczewki.

The IOP was measured in large groups of patients with an implanted posterior chamber lens with or without the use of natrium hyaluronate. It was established that implantation of an artificial lens alone does not influence the value of the intraocular pressure. In cases when natrium hyaluronate was used the pressure was slightly higher but only exceptionally it exceeded 35 mm Hg (most frequently in persons with glaucoma existing before the cataract extraction). The IOP was controlled in the course of several days in all the patients without any harmful consequences for the visual function.
