[Postoperative endophthalmitis].

PURPOSE: Is to establish the risk factors, the treatment and the prognostic factors at the patients operated for cataract, who developed earl endophtalmitis after the operation. MATERIAL AND METHOD: We studied 14 eyes which were operated for cataract who developed endophtalmitis after the the operation. RESULTS: At all patients the general treatment associated antibiotics (Cefalosporine) with steroids (high doses) and the local one was with mydriatics and steroids. After the treatment, we obtained a visual acuity between 0.7-1 at 11 eyes, visual acuity between 0.400,6 in 3 eyes and 2 eye had a visual acuity under 0.1. CONCLUSIONS: The postoperative endophthalmities is a complication which affect the functional prognosis of the patients operated for cataract.

[Secondary implantation of posterior chamber intraocular lenses].

PURPOSE: Is to establish the possibilities of secondary implantation of posterior chamber intraocular lenses, complications and functional results obtained. MATERIAL AND METHOD: We revied 26 aphakic eyes which were secondary implanted with posterior chamber intraocular lenses ş PC IoL). RESULTS: At 16 eyes were implanted standard PC IaL and at 1 o eyes we used scleral fixation PC IoL. Early postoperative complications of standard PC IoL were: uveitis in 4 eyes, dislocation at one case and late postoperative complications were: bulous keratopathy in one eye, secondary cataract in 4 eyes and at 3 eyes dislocations. At scleral fixation PC IQL we had in the early postoperative period secondary glaucoma in 2 eyes and in the late period one eye had retinal detchement and in 2 eyes persist ocular hypertonia. CONCLUSIONS: Posterior chamber intraocular lenses is the optimal solution in correction of aphakia.

[Correlations between ocular biometry and post-surgical refraction].

PURPOSE: To show the importance of ocular biometry in establishing the power of intraocular lens. MATERIAL AND METHOD: We studied 212 eyes operated in the University Eye Hospital from Cluj-Napoca by planned extracapsular extraction with intraocular lens implantation. Before operation there was performed ocular biometry, using SRK II formulas for calculation of intraocular lens. At 6 weeks after operation, we checked the ocular refraction by dioptronometry and we established the optical correction of the patients. RESULTS: The standard error was statistically significantly in all cases. In 84.19% of cases it was performed visual acuity with optimal correction over 0.7. CONCLUSION: The ocular biometry represents significant factor in obtaining a very good visual acuity after cataract operation.

[The explantation and implantation of artificial crystalline lenses].

UNLABELLED: THE PURPOSE of the study is to evaluate the causes of explantation and replacement of different types of intraocular lenses. MATERIAL AND METHOD: We performed a study of 1060 eyes operated for cataract in the University Eye Hospital between 1992-1996, following the number of explantation and replacement of intraocular lenses (IOL), the types of IOL and the causes of explantation. RESULTS: We performed 8 explantation of IOL (0.75 g) for pseudophakic bullous keratopathy (1 case), chronic uveitis (3 cases), secondary glaucoma (2 cases), suppurative uveitis (1 case), cystoid macular oedema (1 case). From the 8 explantation of IOL, 3 were anterior chamber intraocular lenses (AC-IOL) and 5 posterior chamber intraocular lenses (PC-IOL). We performed reposition in 4 cases of IOL. The most frequent cause of explantation was chronic uveitis and secondary glaucoma. CONCLUSION: Explantation is indicated in certain cases of IOL complications without response on medical treatment.

[Etiopathogenic consideration in the development of retinal detachment in aphakic and pseudoaphakic eye].

PURPOSE: Is to evaluate the risk factors implicated in the development of retinal detachment in aphakic and pseudophakic eyes. MATERIAL AND METHOD: We studied 46 cases operated for cataract by planned extracapsular cataract extraction with or without intraocular lens, wich developed after the operation retinal detachments. RESULTS: Retinal detachment appeared in 2.98% cases of EEC with AC-IOL and in 0.56% in EEC with PC-IOL. We performed Yag laser capsulotomy in 4 cases. Retinal detachment appeared in 12 cases between 6-12 months. The most frequent breaks causing retinal detachment where "horse shoe tears" in 23.4% of cases and tears in 14.89% cases. CONCLUSIONS: 1. High myopia and peripheral retinal degenerations are risk factors in the development of retinal detachment after the cataract operation. 2. Vitreous loss facilitates the appearing of vitreo-retinal tractions followed by retinal detachment. 3. PC-IOL reduces the frequency of retinal detachment by the stabilisation of the eye and limiting the ophthalmodonesis.

[Postoperative induced astigmatism].

PURPOSE: Is to evaluate the astigmatism induced by cataract surgery, ethiological factors and ways of prophilaxies and treatment. MATERIAL AND METHOD: We followed a number of 211 eyes operated for cataract by planned extracapsular extraction with intraocular lens implantation, in Ophthalmological Clinic from Cluj-Napoca. All the pacients had limbal incision and the suture was performed with 9.0 suture, after the operation the treatment consisted in local drops with steroids. REZULTS: The astigmatism induced by the surgery was direct in 53.08% of cases and indirect in 46.92%. The position of the axes was 0-900 in 72.51% and oblique in 27.48%. The optical correction of astigmatism was with combined spherocylinder glases in 57.34% and only with cilinder in 42.65% of cases. CONCLUSIONS: 1. The induced astigmatism by cataract surgery is in relation with the incision, suture and IOL. 2. Correction of astigmatism is possible with optical correction, repearing the suture or with refractive surgery. 3. The prevention of astigmatism over 1.5 D is by using Troutmann keratometer and to evidence the congenital astigmatism.

[YAG laser capsulotomy in secondary cataract].

UNLABELLED: The purpose of the study is to evaluate the modern possibilities of performed by laser YAG in secondary cataract. MATERIAL AND METHOD: We performed a study on 200 eyes with secondary cataract operated in the University Eye Hospital from Cluj-Napoca during 1991-1997. RESULTS: We had 95 male and 105 female, with age between 30-90 years old. The capsular fibrosis was present in 86% of the cases. Secondary cataract was present in 13.33% of the cases with PC-IOL. Functional results showed a visual acuity between 0.7-1 in cases from the 50 cases review after 1 week after YAG Laser. CONCLUSIONS: 1. Secondary cataract is the most frequent complications of PC-IOL which influence the visual acuity. 2. YAG laser capsulotomy is a modem, efficient and non-invasive method to solve the secondary cataract.

[The therapeutic aspects in intermittent divergent strabismus].

PURPOSE: Is to evaluate the possibilities of treatment in intermittent divergent squint at children and young adults. MATERIALS AND METHOD: We studied an group of 66 patients treated in the University Clinic of Ophthalmology from Cluj-Napoca. RESULTS: The most frequent type of intermiTtent divergent squint (IDS) is the type of excess of divergency (25.76%). In 46.9% the onset was between 2-6 years. In 69.7% visual acuities were equal and stereopsis was present in 74.24%. Hyperopia +/- astigmatism was present in 69.7%. The treatment of intermittent exodeviation was conservative in 51.5% and surgical for first intention in 39.3%. CONCLUSIONS: 1. The most frequent type of intermittent exodeviation is by excess of divergency. 2. The treatment of exodeviation is an optical, orthoptic and surgical treatment. 3. The surgical technique depends on the type of intermittent exodeviation.

[The correction of myopic astigmatism by refractive keratotomy].

PURPOSE: To determine the efficacy and the predictability of refractive keratotomy in the myopic astigmatism. METHOD: 15 patients (23 eyes) who had been operated on with myopic astigmatism; 4 eyes with simple astigmatism and 19 eyes with compound astigmatism, 1 patient had myopia at one eye and myopic astigmatism at the other. It were performed tangential incisions ("T"), curved incisions ("C") and simple Ruiz with or without radial incisions. The patients were reviewed after 3.6 and 12 month from the operation. RESULTS: Better visual acuity with no correction. The only postoperative complication was under correction. CONCLUSIONS: Refractive keratotomy is recommended in myopic astigmatism and especially with anisometropia.

[Chandler's basal iridectomy. Our observations on surgical indications, technic and value].

Basal iridectomy is a pupillary bypass having a prophylactic role, when made on an eye with potential glaucoma, and a curative role when performed on an eye with primary narrow angle glaucoma in the reversible stage of the disease. The authors present their experience on 37 eyes, using Charleux-Etienne's technique that, compared with Chandler's technique is more advantageous: the limb remains intact for a possible future operation, it is simple, rapid, without risks, efficient and elegant.

[The correction of myopia by radial keratotomy].

PURPOSE: to determine the efficiency and the predictability of the operation in different stages of myopia without help from corneal pachymetry. METHOD: 28 patients (43 eyes) who had been operated on with myopia between -1.5 and -12D were reviewed after 3,6 and 12 month from the operation. Simple radial keratotomy was done. RESULTS: better visual acuity with no correction. Visual acuity with admitted correction (max 3D) in comparison with the other eye was substantially improved in all cases. The only postoperative complication was under correction, frequent in myopia more than 6D. CONCLUSIONS: refractive keratotomy seems to be necessary in single eye myopia and anisometropia.
