[Refractive surgery of the lens in severe myopia].

PURPOSE: To evaluate the visual outcomes in high myopic eyes undergoing clear lens extraction with intra ocular implant. MATERIAL AND METHODS: 33 high myopic eyes (range: -10 to -25 D) underwent clear corneal lens extraction and implantation of posterior chamber intraocular lens. RESULTS: 84,84 % myopic eyes had postoperative corrected visual acuity > 0,3. In 1 case we had a posterior capsular rupture during the insertion of IOL, requiring a sulcus fixation of the IOL. In 3 eyes we had opacification of the posterior capsule. CONCLUSIONS: 1. Clear lens extraction with PC-IOL performed in high myopic eye at adults older than 45 years is a safe and effective refractive procedure. 2. Preoperative patient education and counseling regarding visual is critical in maximizing patient satisfaction. 3. The functional results depend on the chorioretinal myopic lesions.

[Correction of refractive errors in children with contact lenses].

PURPOSE: To appreciate the indications, complications and visual outcomes in the correction of refractive errors with contact lenses at children. MATERIAL AND METHOD: We studied 15 eyes from nine kids. The times prescription included: history (motivation of wearing contact lenses), ocular refraction (with cycloplegia), best corrected visual acuity, keratometry, the corneal diameter, slit lamp examination, the selection of contact lens and follow up. RESULTS: The age of patients varied between several months to twelve years. The refractive errors in which we used contact lenses were: aphakia--6 eyes, myopia--6 eyes, hyperopia--3 eyes. The types of contact lenses were for permanent use--8 eyes and discontinuity use--7 eyes. We didn't have any major complication. The best corrected visual acuity with contact lenses was: 0.1-0.3 at 4 eyes, 0.4-0.6 at 2 eyes and one at 7 eyes. CONCLUSIONS: (1) Contact lenses represent the optimal correction of anisometropia after congenital or traumatic cataract operation in children. (2) The quality of vision obtained with contact lenses represents an important factor in the prevention and treatment of amblyopia.

[Explantation and replacement of intraocular lenses].

PURPOSE: to evaluate the reasons for explantation of different types of intraocular lenses. MATERIAL AND METHOD: We studied 27 eyes operated previously for cataract and which developed in postoperative period intraocular induced complication, demanding explantation. RESULTS: In 51.85% cases we explanted anterior chamber IOL, in 40.74% eyes posterior chamber IOL and in the rest pupillary IOL. Reasons of explantation were according to the artificial lens: in 4 cases for edematous keratopathy, chronic uveitis in 2 eyes and descentration in 8 eyes. Reimplantation was performed at 19 eyes, in 10 cases with standard posterior chamber IOL and in 9 cases with scleral sutured posterior chamber IOL. CONCLUSIONS: The main reason for explantation in anterior chamber IOL is the edematous keratopathy and malpositions for posterior chamber IOL.

[Postoperative complications of refractive cornea surgery with excimer laser, Lasik technique].

PURPOSE: To determine the postoperative complications of laser Excimer surgery, LASIK technique. MATERIAL AND METHOD: We studied 142 eyes with different refractive defects operated with laser Excimer. RESULTS: The early postoperative complications were: DLK stage II/III--6 eyes, Hase--24 eyes, Epitelial Ingrowth in 2 eyes and Central Islands in 2 cases. Late postoperative complications were: secondary glaucoma after steroids administration in 1 case and subcorrection in 19 eyes. CONCLUSION: A quickly treatment of postoperative complications after LASIK technique assure the estimated functional results.

[Endothelial dysfunction in patients with open-angle glaucoma and atheromatous lesions].

UNLABELLED: A number of observations revealed that the haemodynamic alteration may contribute to pathogenesis of glaucomatous neuropathy. Endothelial dysfunction associated with atherosclerosis impaired the endothelial dependent vasodilatation. PURPOSE: To evaluate the relationship between the endothelial dysfunction (assessed by plasma NO level) and carotid stenosis degree în primary open angle-glaucoma patients. METHODS: Carotid ultrasonography and plasma NOx level (nitrite and nitrate) were obtained from 3 groups of patients: group 1-patients with primary open angle-glaucoma and carotid stenosis; group 2-patients with carotid stenosis and group 3-healthy subjects. RESULTS: A significant lower NO level (compared with group 3) and a significant higher carotid stenosis (compared with group 2) were found în primary open angle-glaucoma patients. There was a significant correlation between the NOx level and carotid stenosis. CONCLUSIONS: Assessing the carotid atherosclerotic plaques may be benefical for the patients with primary open angle-glaucoma. Pharmacological neuroprotection with NO precursors may be useful for the patients with carotid stenosis associated with primary open angle-glaucoma.

[Arterial hypotension-risk factor in nonarteritic anterior ischemic optic neuropathy].

PURPOSE: To determine whether a decrease a arterial blood pressure may be a risk factor in occurrence of non-arteritic anterior ischemic optic neuropathy (NAION). METHODS: Two groups of patients were followed up: group I--with arterial hypertension treated with hypotensive therapy and without NAION.; group II--with arterial hypertension treated with hypotensive drugs and NAION previously diagnosticated--Ophthalmologic evaluation (including visual acuity, visual fields, intraocular pressure, slit lamp and ophthalmoscopic evaluation, relative afferent pupillary defect) was performed. Systemic evaluation consist in blood tests (including erythrocyte sedimentation rate and Creative protein), echocardiography and 24-hours blood pressure monitoring. RESULTS: A significant low blood pressure was found at the patients with affected eyes (with NAION) in comparison to the patients with unaffected eyes. CONCLUSIONS: Decrease of blood pressure may be considered a characteristic risk factor of NAION, leading to a vascular insufficiency in the optic nerve head.

[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.

[Phacoemulsification and diabetic eye].

THE PURPOSE OF THIS STUDY: Is to display the influence of diabetes on the course of the operation, postoperative complications and functionals results in operated primary cataract. MATERIAL AND METHODS: We performed a study on 134 eyes with cataract and diabetes operated in the Universitary Eye Hospital and Optilens Eye Clinic from Cluj-Napoca. RESULTS: The majority of patients (83.58%) had noninsulinodependent diabetes. Background diabetic retinopathy was present in 27 cases, associated with the diabetic maculopathy in 8 eyes. In 3 cases was present preproliferative diabetic retinopathy and in one eye it was discovered proliferative retinopathy. EEC + PC-IOL was performed in 81 eyes, mini-nuc in 37 cases and in 16 eyes phacoemulsification with PC-IOL. Postoperative the complications were less in the cases operated with mini-nuc and phacoemulsification. Visual acuity was better in eyes without diabetic retinopathy. CONCLUSIONS: 1. The modern surgical techniques of cataract surgery reduce significant the frequency of postoperative complications. 2. Functional results depends on the presence of diabetic retinopathy.
